Introduction to cosmetic plastic cosmetic tube production

Plastic cosmetic tube manufacturer introduces the main components of plastic cosmetic tube: plastic cosmetic tube is mainly made of polyethylene or polypropylene and other materials added with a variety of organic solvents. Plastic cosmetic tubes are mostly plastic products. The two materials, polyethylene and polypropylene, are tasteless and used to fill cosmetics. However, once polyethylene is corroded by high temperature or acid, it will slowly dissolve and release organic solvents, which will cause harm to the human body. Plastic cosmetic tube is made of polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, and after adding corresponding organic solvents, after high temperature heating, it is blown, extruded, or injected through a plastic mold Molded plastic container. Plastic cosmetic tube has the characteristics of not easily broken, low cost, high transparency, and food-grade raw materials.

l. Regardless of what raw material the plastic cosmetic tube manufacturer chooses, the plastic cosmetic tube must first meet the requirements of no peculiar smell. Due to the wide variety of main raw materials available, it is necessary to select the comprehensive performance of the raw materials. Generally, the selection of tablets is high. Density polyethylene, polypropylene cosmetic tube, if transparency is required, polyester cosmetic tube (PET cosmetic tube) can be used, if high barrier performance is required, and light-blocking, opaque, brown PET cosmetic tube is used, and liquid formulation drugs generally use polypropylene Cosmetic tube or polyester cosmetic tube is used as the main raw material. At present, the domestic nutritional health products and food packaging cosmetic tubes are mainly made of PET or HPDE, and the cover of the cosmetic tube is made of PP.

2. The tightness and water vapor permeability of the cosmetic tube and cover. Tightness and water vapor permeability are two important technical indicators of plastic cosmetic tube, and they have an important influence on the stability of the packaged product.

3. The plastic cosmetic tube supplier guarantees the quality system. Auditing suppliers has become an important part of purchasing plastic cosmetic tubes. Through the audit, it is possible to make a comprehensive and correct assessment of the comprehensive level of software and hardware facilities, technical equipment and quality of the cosmetic tube production plant.

4. Quality standards for plastic cosmetic tube products. From the product quality standards of the cosmetic tube suppliers, the pros and cons of the product quality can be analyzed and judged.

There are four major trends in the development of plastic cosmetic tubes at this stage, including enhancing recyclability, saving energy and reducing consumption, extending the preservation period of nutrients, and broadening the scope of application. With the aid of new additives, the easily recyclable PET plastic cosmetic tube can replace glass cosmetic tube and polyethylene PE plastic cosmetic tube in more fields. The concepts of recycling, energy saving, and sustainable development have become more and more popular, and plastic cosmetic tube manufacturers are also working hard to find such solutions. To

It is understood that plastic cosmetic tube manufacturers have begun to widely use PET plastic cosmetic tubes. At present, when the PET plastic cosmetic tube is recycled, it can only be used in a downgrade, from transparent products to colored product packaging. To

How is the plastic cosmetic tube produced, and what process is there for the plastic cosmetic tube?

Manufacturers of plastic cosmetic tubes have certain production processes and methods during production. Among them, plastic cosmetic tube processing methods include: extrusion blow, injection molding, calendering, blow molding, molding, lamination, casting, and many other methods.

How are plastic cosmetic tubes produced? There are two commonly used production processes for plastic cosmetic tubes:

The first is the extrusion and blowing process, that is, the plastic raw materials are added to the extruder, the molten parison is extruded by heating, melting and plasticizing, and then placed in the cosmetic tube mold for inflation molding. After cooling and shaping, it is taken out of the mold and repaired. The finished product is obtained after scrapping. This process is mainly used to produce polyethylene and polyvinyl chloride plastic cosmetic tubes, such as cosmetic tubes; The second is the injection stretch-blow process, that is, plastic raw materials are injected into a tubular parison through an injection molding machine, and then placed into the cosmetic tube mold After stretch blow molding, the finished product is obtained after cooling. This process is mainly used to produce PET plastic cosmetic tubes, such as cosmetic tubes.

How is the plastic cosmetic tube produced, and what process does the plastic cosmetic tube have? After the plastic cosmetic tube is passed, blow molding, the plastic is heated and melted, and then pressed into a special blow molding mold and the internal air pressure, pressure, and mold plastic form the shape of the final product, because the shape of the cosmetic tube is pressured outward Time, so it is emphasized that when the cosmetic tube itself is inward, the heating temperature reaches a certain level, it will soften the plastic, and the pressure resistance will decrease, so the cosmetic tube will become smaller and smaller.

At present, the cosmetics packaging industry is developing rapidly, especially plastic packaging. It is not unfamiliar to everyone how to mention plastic cosmetic tube. We can see the use of plastic cosmetic tube everywhere in our daily life. For example, skin care products and cosmetics are all made of plastic. The cosmetic tube is packaged. Plastic cosmetic tube has a strong competitive advantage in the choice of product packaging materials. This is mainly reflected in the following aspects:

On the one hand, the selection of raw materials for the plastic cosmetic tube has been tested and approved by the cosmetic tube supplier and the quality certification body; on the other hand, in terms of material, the plastic cosmetic tube is mainly made of plastic, and the plastic produced by the plastic cosmetic tube manufacturer The most prominent feature of cosmetic tube is its light weight and it is not afraid of falling. Therefore, plastic cosmetic tube is widely used in various fields with its unique competitive advantages. For example, in the medical field, plastic cosmetic tubes are the main medicine packaging equipment, especially solid or powder medicines. Plastic tube packaging is often used, which not only guarantees the safety of medicines, but also greatly reduces the cost of use.

Plastic cosmetic tube must be non-toxic and odorless

Plastic cosmetic tubes are widely used in many fields, whether in industry or life, but no matter what raw materials are selected for liquid plastic cosmetic tubes, they must first meet the requirements of non-toxicity and odor-free. It must be non-toxic and odorless, and environmental protection and health are the most important.

Plastic cosmetic tube manufacturers recycle secondary materials to produce plastic cosmetic tubes, which are plastic cosmetic tubes made from raw materials made from waste plastics that have not been strictly recycled, cleaned and disinfected. These plastic cosmetic tubes need to meet standards in terms of hygiene and quality. The reason why these secondary materials can prevail in the market lies in their extremely low prices. Compared with new materials, these substandard secondary materials are even less than half the price. Some plastic cosmetic tube manufacturers use or mix them with new materials in order to reduce costs. If these plastic cosmetic tubes are circulated into packaging fields such as medicine, they will be more harmful to people if they come into direct contact with medicines. At the same time, competition is unfair for manufacturers who use new materials to produce plastic cosmetic tubes. In addition, the production of these secondary materials often creates harsh environmental problems.

For the plastic cosmetic tubes on the market, if we generally do not pay attention to them, we will not distinguish between the quality of them and whether they are harmful to human health. However, if you look closely, we sometimes find that some plastic cosmetic tubes have poor gloss and contain impurities. Yes, what you see is a plastic cosmetic tube made of secondary materials.

2. The tightness and water vapor permeability of the cosmetic tube body and cover. Tightness and water vapor permeability are two important technical indicators of liquid plastic cosmetic tube, and they have a vital impact on the stability of the packaged product.

3. Quality standards for plastic cosmetic tube products. The pros and cons of product quality can be analyzed and judged from the product quality standards of the manufacturer.

4. Quality assurance system. Auditing suppliers has become an indispensable part of purchasing liquid plastic cosmetic tubes. Through the audit, a comprehensive and correct assessment of the comprehensive level of the plastic cosmetic tube manufacturer's software and hardware facilities, technical equipment, and quality can be made.
