What is Thermoforming Tray?

Thermoformed trays are also called plastic inner trays. Thermoformed trays are plastics that use thermoforming manufacturing process to make hard plastic sheets into specific grooves. The products are placed in the grooves to protect and beautify the products.

Thermoformed trays also have material handling trays. Thermoformed trays are mostly used for convenience.

Compared with other types of packaging on the market, thermoformed plastic trays are hygienic, environmentally friendly, low-cost, and easy to clean.

They are widely used in electronics, pharmaceuticals, food and other industries to play the role of anti-static, foil, shockproof, separation and fixation.

The types of thermoforming trays mainly include plastic drip trays, plastic shipping trays, disposable shipping trays, foam trays, automation trays recycling thermoformed trays, vacuum forming trays, etc. This article will take you to learn more about thermoforming plastic trays.

Thermoforming Trays Materials

The raw materials of thermoformed products are only plastic sheet, and the thickness of the film generally does not exceed 1.5mm. Commonly used sheets include: PVC, PET, PP, PS and based on this, flocking sheets, gold-plated sheets and anti-static sheets.

Environmental advantages of thermoformed trays

Reusable

Most thermoformed trays are made of environmentally friendly plastic materials, which greatly reduces environmental pollution and resource consumption, and meets the environmental protection requirements of modern society.

Reusable trays are used frequently in corporate logistics, so recycling within the company is a common method.

Enterprises can reuse used recyclable vacuum forming trays after cleaning, disinfecting and other procedures. In addition to recycling within the company, it is also a common method to send recyclable thermoformed trays to other factories for recycling.

Enterprises can classify and package used recyclable thermoformed trays and send them to other factories that have cooperative relationships with the enterprise for recycling.

Environmentally Friendly

Recyclable thermoformed trays are made of degradable materials, which will not cause pollution to the environment and comply with the environmental protection requirements of modern society.

Save Costs

Recyclable thermoformed trays adopt a reusable design, which can reduce logistics costs and save enterprises' operating costs.

High Reliability

Recyclable thermoformed trays have strong carrying capacity, light weight and good durability, which can meet the logistics needs of enterprises and bring greater value to enterprises.

Twin Sheet Thermoformed Trays

The twin sheet thermoformed tray consists of a top cover and bottom bracket with a lock and a foldable enclosure to form a complete set of combined plastic trays. The top cover and bottom bracket are made of HDPE.

It is formed using a one-time twin sheet thermoforming process. The middle hoarding can be made of PP (polypropylene resin) plastic hollow board or seven-layer corrugated cardboard to make a foldable hoarding.

The entire series is designed to be recycled, and the top cover and bottom bracket can be recycled for up to ten years.

Plastic hoardings and corrugated paper hoardings can also be recycled multiple times and replaced.

This design can greatly reduce customers' logistics operations and warehousing costs.

The middle panels of the tray are designed to be foldable, and the top cover and bottom bracket can be embedded or stacked, which can save 50% of storage space compared with traditional packaging.

The thermoformed top cover and bottom bracket are both thermoformed from two HDPE sheets at one time, which is strong and durable.

Is the assembly or disassembly of thermoformed trays extremely convenient?

One person can complete the disassembly or assembly in a few minutes without using any tools. The top cover and bottom bracket are each designed with four quick locks, which can lock the hoarding, so there is no need to bundle it, saving packing materials and labor costs.

Constraints on the Development of Thermoformed Trays

The Usage Method is Backward

The advantages of thermoforming trays cannot be fully utilized. The thermoformed tray itself is a unitized logistics device born to cooperate with efficient logistics.

It can be said that the tray is the connection point throughout all aspects of the modern logistics system.

However, in our actual use, due to the inconsistent specifications, trays cannot be circulated and used in the logistics operation chain, and are only limited to within the enterprise.

The Cost of the Circulation Process is Too High

From the survey, it can be found that the vast majority of companies' PVC pressure forming trays are recycled within the company, so that the company's products undergo manual handling and loading and unloading many times, which greatly reduces work efficiency and correspondingly increases the circulation cost of the products, thus Reducing the competitiveness of the product in the market.

Difficult to Conform to International Standards

Due to the inconsistent specifications and standards of PVC thermoformed trays, the use of trays in various countries cannot match international transportation equipment (such as international containers, etc.).

In order to adapt to relevant international transportation tools, companies have to order trays from tray manufacturers that are inconsistent with the company's turnover specifications, thereby increasing the company's export costs and reducing the international competitiveness of its products.

Application of Thermoformed Trays

There are many types of thermoformed trays. Trays are one of the types of thermoforming in the thermoforming industry. This type of tray has a strong bearing capacity.

According to the shape, structure and weight of the item, thermoforming tray is suitable for withstanding the force. There are also many thicknesses of materials used.

The choice depends on the packaging material needs of the packaged items. This type of thermoformed tray is commonly used in the electronics industry, toy industry, stationery industry, technology product industry, cosmetics industry, health care products industry, etc.

In terms of use, the commonly used materials for this type of trays include PVC and PS hard film. Generally, transparent thermoformed trays are more commonly used in thermoformed packaging. Other colors can be selected according to individual needs.

Thermoformed trays are widely used in food, medicine, electronics, chemicals, logistics and other industries. They have the advantages of light weight, beautiful appearance, moisture-proof, shock-proof, and anti-oxidation.

Compared with traditional wooden trays, thermoformed trays are more hygienic, durable, easy to clean and disinfect, and meet the environmental protection and hygiene requirements of modern enterprises.

How to Choose High-Quality Thermoformed Trays

When choosing a high-quality thermoformed tray, you need to comprehensively consider the actual needs and choose the tray that suits you.

At the same time, it is also very important to choose a regular thermoformed tray manufacturer.

Thermoforming Trays Material

Thermoformed trays are typically made from polyethylene (PE) or polypropylene (PP), both of which are highly durable and recyclable. You can choose according to your specific needs when choosing.

Tray Size and Shape

The size and shape of thermoformed trays should be determined based on the cargo required to be loaded.

The size of the tray should be slightly larger than the size of the goods so that the goods can be placed stably on the tray.

Tray Load-Bearing Capacity

The load-bearing capacity of a thermoforming tray is determined by its material and construction. When selecting a tray, you should consider whether its load-bearing capacity can meet the requirements of the goods.

Tray Price

The price of thermoformed trays varies based on factors such as material, size, shape, and load-bearing capacity.

When choosing a tray, you should consider its cost performance and choose a tray that suits you.

Cases

Automobile Industry

Twin sheet thermoforming: dedicated thermoforming trays for the automotive industry

For Tier 1 automotive suppliers, in the process of transporting those large mechanical parts or bulk small parts from their factories to the OEM automotive assembly line, they usually need to use large customized trays in order to stack the goods in an orderly manner. Avoid collision damage.

For example, the custom-made tray below is very suitable for transporting those precision mechanical parts to the OEM's automobile assembly line. The forminging process includes the following processes:

First, two sheets are placed at designated positions on the orifice plate of the thermoforming machine, and then the clamp automatically lowers and a moving intermediate frame brings in the other two sheets.

Two sets of halogen lamp heaters will quickly heat the four sheets according to the heating path set by the computer. Precise temperature control is achieved through a fine-hole grid of photocells.

During this process, it is necessary to ensure that the sheet is flat when heated.

Then, the mold is closed. Under the action of a clamping force of hundreds of thousands of Newtons, the two sheets are combined into a strong structural panel.

By introducing a certain pressure of air between the two layers of sheets, the sheets and the mold can fit more closely, and it can also have a certain cooling effect.

After the mold has cooled, immediately open the moving middle frame and remove the two formed trays.

Finally, the robot takes the formed product out of the mold, and then puts the next set of four preheated sheets into the mold to start the next production cycle. One product can be produced every 5 minutes.

Chemical Industry

For the chemical industry, the issue of safe transportation of goods is very important. Thermoformed trays solve this problem with their natural advantages and improve the safety and stability of cargo transportation. The advantages of thermoformed trays include the following:

1. Durability

Thermoformed plastic trays are more sturdy and durable because they can not only bear a large weight but also avoid corrosion by chemical products, so they are widely used in the chemical industry.

2. Lightweight

The main materials of thermoformed trays are thermoplastics, so they are lighter. Whether in cargo transportation, stacking, or storage, labor intensity is greatly reduced. At the same time, it also brings great convenience to the logistics industry.

3. Environmentally friendly materials

Compared with traditional wood or paper materials, thermoformed trays are a more environmentally friendly material. Using thermoformed trays reduces logging and felling of trees and reduces the impact on the environment.

4. Recyclability

The thermoformed plastic tray is made of ultra-high molecular weight polyethylene and can be recycled. Used thermoforming trays can be recycled into new trays, reducing the waste of resources and better protecting the environment.

5. Hygiene

Product transportation in the chemical industry often requires attention to the hygienic environment. The surface of the thermoformed tray has almost no pores and gaps, so it will not accumulate bacteria and viruses, and is highly safe. It is also easy to keep clean and has a long service life.

Conclusion

As an important logistics packaging tool, thermoformed trays play an important role in logistics, manufacturing and retail industries. Its lightweight, durable, easy to clean and environmentally friendly features make it an ideal alternative to traditional wooden and metal trays.

At the same time, with the development of science and technology and the increase in demand, the application prospects of thermoforming trays will be broader. We believe that in the future development, thermoformed trays will have more applications and innovations.

The Rise of Heavy Gauge Thermoforming in Medical Manufacturing

With the continuous emergence of new materials and new technologies, multi-layer heavy gauge thermoforming is used in the field of hospital medical equipment shell molding and manufacturing, opening a new chapter in structured products for hospital medical equipment shells.

To this end, it is necessary to explore the relevant elements of heavy gauge thermoforming products for hospital medical equipment casings, consider the optimization path of the thick gauge thermoforming process for medical equipment casings, and improve the quality of hospital medical equipment casing products.

As a plastic processing technology, the main principle of pressure forming is to heat a flat hard plastic sheet to soften it, then use vacuum to adsorb it to the surface of the mold, and then cool it into shape. It is widely used in plastic packaging industry, pharmaceutical packaging sectors, healthcare sector, medical device packaging trays, food packaging industries, pharmaceutical industry, advertising, automotive industry decoration and other industries.

After a whole product is produced, it must be separated into individual small products, and then there will be some leftover edges of the product. Commonly used materials in blister packaging factories include PP, PET, PVC, PE, etc. As a sterile barrier system, medical packaging blister boxes are accepted by more and more medical devices, and PETG material used in medical applications is favored due to its strong. The market growth is significantly.

Ⅰ. Analysis of Design Elements of Medical Equipment Shells

Geometry and Accuracy

The geometric dimensions of the thermoformed shell include: the dimensions from the cutting surface to the molding surface of the thermoformed product, and the dimensions from the cutting surface to the cutting surface, which are directly related to the plate thickness, material properties, and molding process.

Draft Angle

The thermoforming mold consists of a concave mold and a convex mold with different demoulding angles. Generally speaking, the demoulding angle of the concave mold is 0.5°-1°, and the demoulding angle of the convex mold is 2°-5°.

Shell Rounded Corners

The thermoformed shell should be designed with as large rounded corners as possible, and should not be designed with sharp corners and should be chamfered to ensure that the stress of the thermoformed shell product is appropriate.

Aspect Ratio

The width-to-depth ratio of thermoformed products for medical equipment shells is an important indicator to measure the ease of thermoforming. It represents the ratio of the minimum width to depth of the product. The larger the value, the easier it is to form the thin gauge thermoformed plastics product. The smaller the value, the easier it is to form the thermoformed product. It shows that the thermoformed products are more difficult to form.

Ⅱ. Defects

1. Partial Molding of the Product is Insufficient.

The main causes of defects that lead to insufficient local molding of thermoformed shell thick plate products are:

The plasticity of the board itself is poor. There is insufficient vacuum between the sheet and the mold. The sheet has stretched too much. The mold temperature is low, etc.

2. Product Surface Color Defects.

The main causes of product surface color defects include:

Insufficient heating. Overheating. The mold heating temperature is not high.

3. Product Flow Mark Defects.

The main causes of flow mark defects in products include:

The temperature of the mold and plate is not high. Poor mold temperature control. There is a deviation in the molding process.

4. Product Wrinkle Defects.

The main causes of wrinkle defects in products include: The board sags too much. The plate heating time is too long. The molding angle of the mold is too large.

5. Product Surface Flatness is Insufficient.

The main causes of uneven surface defects on products are as follows:

Insufficient cleanliness of the sheet or mold. The mold vacuum hole is too large. The mold does not have enough vacuum holes. There is a lamellar structure on the mold.

Ⅲ. How to Optimize the Production of Medical Device Shells

Optimization of Product Structure

The shell of hospital medical equipment has a large volume and surface area, so it can be designed in a curved shape to maintain the external beauty of the product structure and better avoid the defects of the thermoforming manufacturing process. The optimization of its structure mainly includes the following aspects:

1. Optimize the depth of the product.

Since there are many products with large barrel depths in hospital medical equipment, this brings great challenges to medical device manufacturers. In order to optimize the product molding effect, concave molding and punch-assisted pressing can be used to make the product sheet The material is heated between the upper and lower molds and a small amount of air is sucked out of the punch and the sheet, so that the sheet is adsorbed on the punch, and then the punch is gradually pressed down so that the sheet is completely adsorbed on the concave mold, and finally demoulded. Through this concave and convex mold-assisted molding method, the draft angle of the equipment shell product can be increased and the width-to-depth ratio of the shell product can be reduced.

2. Optimize the rounding of corners.

Based on the actual requirements of assembly, the corner rounding can be optimized at the junction of medical equipment shell products.

3. Adopt assembly bonding.

For thermoformed shells of hospital medical equipment, assembly bonding can be used instead of undercut designs. Double-layer thermoforming technology is used to replace the optimized process of single-layer thermoforming plate bonding to enhance the strength of the shell product.

Optimization of Process Parameters

Since the materials for hospital medical equipment shells are mainly ABS and ABS/PC, and assembly materials such as PC, HIPS, PET, and PP are used, it is necessary to analyze and optimize the process parameters of these different materials, including the following:

1. Sheet drying time.

This is the shrinkage characteristic parameter of the thermoformed sheet in the dry state, which is directly related to and affects the thermoforming of thick plates for medical equipment shells. When the drying times of different materials are: HDPE is 8 hours, PE is 6 hours, ABS is 8 hours, PC is 6 hours, and ABS/PC is 8 hours, it indicates that the performance of the medical equipment shell thick plate thermoforming product is relatively Stablize.

2. Thermoforming temperature. This is mainly analyzed and optimized from the two aspects of sheet heating temperature and pressure forming mold temperature. Among them: double-sided heating is usually used to heat the plastic sheet, and different molding temperatures are set according to different shapes of products. , making the product consistent with the design requirements. The temperature of the thermoforming mold should be kept appropriate and should not be too high or too low. If the mold temperature is too high, the product will adhere to the mold, causing the product to demould and deform. If the mold temperature is too low, the plate will be deformed. Improper molding may cause defects such as black spots, wrinkles, and cracks in the product. Generally speaking, when the medical equipment shell is thermoformed, the mold temperature is controlled at: HDPE is 50°C, PE is 50°C, PVC is 50°C, ABS is 70-80°C, PC is 120°C, and ABS/PC is 110°C. , indicating that the temperature of the thermoforming mold is appropriate.

Optimization of Mold Design

1. Optimize high-pressure thermoforming mold.

The high-pressure frame thermoforming mold structure can be used to fully form the thick plate thermoforming products of medical equipment shells.

2. Add upper mold to assist molding.

You can add an upper mold to assist in molding to produce cylindrical medical device packaging with large depth and complex shapes to avoid defects such as surface breakage or wrinkles on the surface of thermoformed products.

3. Add mold core-pulling structure.

By adding hinges, bonding blocks and cylinders to the design, the demoulding of thermoformed products can be better assisted.

Raw Material Selection

The selection of raw materials is the basis for ensuring quality. From particles to thermoformed finished products, its requirements are much higher than those of food grade and industrial grade. The material selection of medical-grade vacuum forming boxes must meet ROHS requirements, and meet the requirements of IS010993 "Biological Evaluation of Medical Devices" and ISO11607 "Packaging of Terminal Sterilized Medical Devices" to achieve a complete sterile barrier system and microbial barrier function.

At present, there are many categories of food packaging materials produced in our country, with varying degrees of good and bad, and there are many hidden safety hazards. In particular, industrial PVC replaces PETG (material characteristics, usually medical blue), RPET (a recycled PET material) replaces APET, etc. After high-temperature molding and sterilization, a large amount of harmful substances will be precipitated, including pain-causing substances. , causing the device that was originally used to save lives and heal the wounded to eventually become a "killing" weapon. Therefore, we must choose materials carefully. At present, the main medical PETG include American Eastman 6763 and Korean SKS2008.

Thermoformed Box Structural Design

Before design and development, comprehensive factors such as demand for thermoformed plastics, forecast period, raw material selection, packaged equipment, sterilization methods, and clean opening by medical staff should be fully considered. And ensure the ability of sterilized medical device packaging to maintain sterility levels during the validity period. Therefore, details such as the design of edge banding width, hand tearing position, buckling method, etc. all need to be considered in the design stage.

Thermoforming Mold Selection

Medical thermoforming boxes use aluminum alloy molds. There are many kinds of aluminum materials. However, in terms of overall mold processing accuracy and various performance, 6061 is a better aluminum material. The aluminum material is processed into a mold by CNC. Since the inner core is aluminum, it is easy to achieve thermal balance. Cold water flows around it, which allows the mold to cool down quickly and improves the production efficiency of the vacuum forming box. Because the inner core is aluminum, it is easy to achieve thermal balance and cold water flows around it. Let the mold cool down quickly, increase the speed of goods production, and increase the smoothness of the thermoformed box. Because the cost of aluminum molds is high and the general service life is long, Martin Medical Packaging promises customers that the aluminum molds can be used for 10 years and can be produced repeatedly. can maintain high accuracy. There are many master molds on the thermoformed plastics market made of gypsum powder with a layer of copper on the outer electroplating surface. Not to mention the accuracy and appearance of the finished product, the cleanliness cannot meet the requirements of medical device packaging. The quality of the mold making of the thermoformed box directly affects the details of the finished thermoformed box, so it is recommended to choose carefully.

Conclusion

To sum up, the production of hospital medical equipment shells and medical thermoforming boxes is inseparable from the efficient and advanced thick plate thermoforming process. Vacuum forming must be better adopted by optimizing product structure, molding process parameters, mold design, etc. technology to meet the needs of hospital medical equipment shell use.
