What is stand up pouch?

Stand-up pouch refers to a flexible packaging bag with a horizontal support structure at the bottom, which does not rely on any support and can stand on its own regardless of whether the bag is opened or not. The English name of the stand-up pouch originated from the French Thimonier company. In 1963, Mr. M.Louis Doyen, the CEO of the French Thimonier company, successfully applied for the patent of the Doypack stand-up pouch. Since then, stand up pouch has become the official name application of the stand-up pouch. to date. By the 1990s, it was widely recognized in the American market and then popularized all over the world. The stand-up pouch is a relatively novel form of packaging, which has advantages in improving product quality, strengthening the visual effect of shelves, portability, ease of use, preservation and sealability. The stand-up pouch is made of PET/foil/PET/PE structure laminated, and can also have 2 layers, 3 layers and other materials of other specifications. It depends on the different products of the package. The oxygen barrier protective layer can be added as needed to reduce the oxygen permeability. , extending the shelf life of the product.

Stand-up pouch packaging is mainly used in fruit juice drinks, sports drinks, bottled drinking water, absorbable jelly, condiments and other products. In addition to the food industry, the application of some washing products, daily cosmetics, medical supplies and other products has gradually increased .

Stand-up bags are basically divided into the following five types:

Ordinary stand-up bag: And the general form of a stand-up pouch, adopts the form of four-sealed edges and cannot be re-closed and repeatedly opened. This kind of stand-up pouch is generally used in the industrial supplies industry.

Stand-up pouch with suction nozzle: The stand-up pouch with the suction nozzle is more convenient to pour or absorb the contents and can be re-closed and re-opened at the same time, which can be considered as the combination of the stand-up pouch and the ordinary bottle mouth. This kind of stand-up pouch is generally used in the packaging of daily necessities, for beverages, shower gels, shampoos, ketchup, edible oils, jelly and other liquid, colloidal, semi-solid products, such as the famous CiCi.

Stand up pouch with zipper: Self-supporting pouches with zippers can also be re-closed and re-opened. Since the zipper form is not closed and the sealing strength is limited, this form is not suitable for encapsulating liquids and volatile substances. According to the different edge sealing methods, it is divided into four edge sealing and three edge sealing. Four edge sealing means that the product packaging has a layer of ordinary edge sealing in addition to the zipper seal when it leaves the factory. The zipper is then used to achieve repeated sealing and opening, which solves the disadvantage that the zipper edge sealing strength is small and is not conducive to transportation. The three-sealed edge is directly sealed with a zipper edge, which is generally used to hold lightweight products. Self-supporting pouches with zippers are generally used to package some light solids, such as candy, biscuits, jelly, etc., but four-sided self-supporting pouches can also be used to package heavier products such as rice and cat litter.

Imitation mouth-shaped stand-up bag: Imitation mouth stand-up pouches combine the convenience of stand-up pouches with suction nozzles and the cheapness of ordinary stand-up pouches. That is, the function of the suction nozzle is realized by the shape of the bag body itself. However, the mouth-shaped stand-up pouch cannot be re-sealed. Therefore, it is generally used in the packaging of single-use liquid, colloidal and semi-solid products such as beverages and jelly.

Special-shaped stand-up bag: That is, according to the needs of packaging, new stand-up bags of various shapes produced by changing on the basis of traditional bag types, such as waist design, bottom deformation design, handle design, etc. It is the main direction of the value-added development of self-supporting bags. With the progress of society and the improvement of people's aesthetic level and the intensification of competition in various industries, the design and printing of stand-up bags have become more and more colorful, and their forms are more and more. The development of special-shaped stand-up bags has gradually replaced the status of traditional stand-up bags. the trend of.

What are false eyelashes?

False eyelashes are artificial eyelashes used to beautify the eyes. Generally, by lengthening and thickening the eyelashes, the eyes look bigger, brighter, fuller, and more divine. False eyelashes have a long history, and records of false eyelashes can be found in ancient Egyptian and Roman documents as early as 2000 BC. The materials for making false eyelashes include plastic, cotton, feathers and other materials, and with the use of false eyelashes made of different materials, the effects displayed (for example, exaggerated stage effects) are also different.

False eyelashes are a type of beauty products. The artistic design is used for the eyes, and the eyelashes show a fairy-like temperament. It is specially designed to be transparent, and the color of the colored eyelashes is completely shot on the face. Many fashionable ladies like to use false eyelashes to beautify their eyes, and the correct use will make the eyes beautiful.

Product Usage

It can be used to beautify the eyes every day, make the eyes beautiful, and can also be used to create various stage effects.

Instructions

According to the curvature and length of the eyes, trim off the eyelashes that are too long at the end of the false eyelashes; apply an appropriate amount of eyelash glue evenly to the roots, and let it stand for 20 seconds to maximize the viscosity of the eyelashes; Gently press and fit the real eyelashes at the top, middle, and end of the eye, adjust the eye shape with small tweezers before the eyelash glue is completely dry, and then determine the position; use an eyelash curler to gently clamp the real and false eyelashes together, and the force should not be too large , the separation of true and false eyelashes will weaken the eyes; choose a long type of mascara to fit the true and false eyelashes closely; use eyeliner to fill the gap between the true and false eyelashes, and then adjust the eye shape completely.

The difference between the steam eye mask and the eye mask improved directly through the thermal patch

In addition to the steam eye mask, there is also an eye mask improved by a thermal paste. The appearance of the eye mask is similar to the steam eye mask, and some even have "steam", but it is still very different from the steam eye mask. You should pay attention to the difference. . There are three main differences: (1) Process formula: Generally, the steam eye mask is strictly in accordance with a certain proportion. When the raw material ratio is designed, the amount of iron powder, carbon powder, water and other substances in the internal material is determined, and the amount is precisely fixed. And the eye mask that is directly improved by the thermal paste, its formula is mainly the formula of thermal paste, if it is a "steam" eye mask, a certain amount of water is directly added on the basis of the original formula, such a design itself is unreasonable of. (2) Purity of raw materials: The purity of the internal materials of the steam goggles is generally above chemical purity, so that the heat generation, heat generation time, heat generation stability, etc. are guaranteed, while the purity of the internal materials used in the improved goggles with thermal paste generally cannot reach this level. Requirements, will lead to a series of problems such as insufficient heat generation, short heating time, poor heat generation stability, and uncontrollable steam volume and steam temperature. (3) Safety: As mentioned above, the steam eye mask has strict requirements on the amount of steam, steam temperature, and heating time. For the eye mask improved by the general thermal paste, these are not guaranteed, so that the steam temperature may be too high or suddenly become high, and it is easy to cause burns due to the sensitivity of the eyes. In addition, since the thickness and area of ​​the improved eye mask of the thermal patch are larger, there is a risk of leakage of the inner material.

What is steam eye mask?

The steam eye mask adopts advanced self-heating temperature control technology, which allows the moisture in the air and the iron powder to chemically react inside the eye mask to form a heating body and generate subtle and moist water vapor that cannot be seen by the naked eye. It is a generic name product developed in response to the needs of the eye care market, named for its ability to spontaneously generate heat and steam.

Reaction principle

The reaction principle of the steam eye mask is the reaction principle of rapid oxidation of carbonyl iron powder after contact with oxygen in the air. In order to make the temperature last longer and more constant, the product uses a very precise breathable membrane. Because the product cannot react before use, the material of the bag should be very special. When in use, remove the outer bag and allow the product to be exposed to the air for 30 seconds, the oxygen in the air enters the inside through the micro-permeable membrane. The time and temperature of the heat released is controlled by the oxygen transmission rate of the breathable membrane. If the oxygen permeation is too fast, then there will be too much heat, which is very likely to burn the skin. If the oxygen permeation is too slow, the temperature is too low. After use, it is a dark brown solid, which contains carbon powder, solid (this is edible salt), solid and salts containing magnesium and aluminum. (1) The external reaction principle of the steam eye mask The steam is evenly released through the high-grade medical non-woven fabric, and the warmth of the steam is used to promote the microcirculation of blood in the eyes, relax the tense eye muscles, and relieve eye fatigue and discomfort. (2) The internal reaction principle of the steam eye mask The galvanic battery reaction is used to speed up the oxidation reaction, convert chemical energy into heat energy, and then use the generated heat to stably evaporate the water in the internal material, so as to use the heat and humidity of the steam to relieve eye fatigue and promote eye fatigue. Blood circulation, bright eyesight and other effects. In order to make the temperature last, and the inner bag of the produced heating sheet is exposed to the air, the oxygen in the air enters the inside through the breathable film, reacts with the iron powder, and releases heat. The time and temperature of the heat release are controlled by the oxygen transmission rate of the breathable membrane. If the oxygen permeates too quickly, too much heat is released and the skin may burn. If the oxygen permeation is too slow, there is no temperature. The process of generating steam is the heat release of the internal material, which greatly accelerates the evaporation rate of the water content in the interior, and the evaporated water vapor quickly liquefies when cooled to form steam.
