What are the cosmetic tube materials in the cosmetics we usually use?

Many people know that most of our current cosmetic packaging is tube packaging, the advantage of this packaging is that it is easy to carry and not easy to waste. Just like our facial cleanser, because of the soft tube, it is easy to take away even if the cosmetic capacity is large. When the product is about to run out, by squeezing it, we can use it a few more times, which is also the benefit of the tube.

There are mainly three kinds of cosmetic plastic tubes in popular cosmetic packaging materials, namely: aluminum-plastic composite tube all-plastic composite tube, and plastic co-extrusion tube. These three materials have their own advantages and disadvantages for cosmetic packaging. However, the materials need to be non-toxic and tasteless, and they must be strictly sterilized before they can be put into use because they usually contain some ointments, skin care products, and cosmetics that we use on the face, toothpaste, etc., we must pay attention to hygiene issues. The most commonly used are plastic tubes, which are widely used in the packaging of facial cleansers, conditioners, hair dyes, toothpaste, and other cream cosmetics in the cosmetics industry, as well as the packaging of creams and plasters in the pharmaceutical industry. And the plastic tube packaging is economical, convenient, and easy to carry. Even after high-strength extrusion, it can be restored to its original state and maintain a good appearance. According to data, 60%-70% of tubes are used in the cosmetic industry, 10%-15% are used in the pharmaceutical industry, and about 5% are used in the food industry. So in fact, cosmetic tubes are not only used in the cosmetics industry but also very common in other industries, because they have many advantages and are relatively cheap.

How does a lipstick tube work?

The birth of cosmetic tube packaging--metal tube lipstick is a milestone revolution in the cosmetic industry.

In 1915, American Morris Levy invented a metal cylinder with a small lever on the side of the cylinder to squeeze out lipstick. Women must use the edge of their nail to slide a lever on one side of the tube to move the lipstick to the top of the box. Until then, lip colors were sold in jars or color tubes.

In 1923, James Bruce Mason Jr patented the first rotatable lipstick tube. The lipstick is called a "Mason tube" and has a decorated screw at the bottom for extruding the stick. This rotating lipstick tube design has been used until now. Mrs. Elizabeth Arden and Mrs. Estée Lauder also began selling lipstick in their salons during this period, and these two major brands have been producing lipsticks in rotating tubes to this day.

The composition of the lipstick tube is very simple and can be roughly divided into three parts: the lipstick body, the chute sleeve, and the pushing part. When you use it, you should keep the sleeve of the chute fixed, and then rotate and push the parts. The push part will move in the spiral groove of the sleeve with the pin on the lipstick so that the lipstick can be raised and lowered. There are two horizontal grooves at the beginning and end of the chute sleeve, which allows the lipstick to be positioned when it is rotated to the end. The movement process of rotating lipstick is very simple.

Cosmetic packaging and printing technology

Silkscreen: Silkscreen will produce obvious bumps because of the ink. Regular bottles (cylindrical) can be printed at one time. Other irregular packages require one piece at a time. Multiple colors need different times of fees. It is divided into self-drying ink and UV ink. The self-drying ink is easy to fall off and can be wiped off with alcohol. UV ink has obvious bumps and is difficult to wipe off.

Hot stamping: Hot stamping refers to the process of transferring the hot stamping material or hot plate pattern to the object to be hot by hot pressing on objects such as paper, cardboard, fabric, coating, etc., so there will be no unevenness of silk screen printing. But hot stamping cannot be directly implemented on PE and PP materials. It needs to be heat-transferred first and then hot-stamped. If there is a good hot stamping paper, it can also be hot stamped directly. Hot stamping is not allowed on aluminum-plastic. The choice of material should be careful.

3.Water transfer printing: Water transfer printing refers to printing the required color lines on the film that has undergone special chemical treatment, and sending it flat to the surface of the water. The action of water pressure uniformly transfers the color pattern to the surface of the product, and then the film is automatically dissolved in water. After washing and drying, a transparent protective coating is added to the surface of the packaging, giving the product a completely different visual effect.

4.Thermal transfer printing: The transfer printing process transfers the exquisite pattern on the transfer film to the surface of the product through one-time processing (heating and pressure) of the thermal transfer machine. The product quality will largely be improved,. However, due to the high technical content of this process, many materials need to be imported, which is expensive.

5.Offset printing: Offset printing is mostly used in the polyfoil tube or plastic tube. The silk screen printing must be used if the color is white because the offset printing will have the background color showing through, and sometimes a layer of bright film or sub-film will be attached to the surface of the tube.
