Plastic Cosmetic Hose Packaging Technology - Cosmetic Tube Manufacturer

2021-11-02

Plastic cosmetic tube from cosmetic tube manufacturer is widely used in many fields. It is not in industry or life, but no matter what raw materials you choose to make cream plastic cosmetic tube, you need to meet the requirements of clean, no strange taste and so on. To be clean and free of strange odors, clean cosmetic tube is important. Secondary material production plastic cosmetic tube is some plastic cosmetic tube produced by raw materials made of waste plastic without strict recycling and cleaning.

These plastic cosmetic tubes are difficult to meet in terms of hygiene and quality. The reason why these two makings can prevail in the market lies in its low price, compared with new makings, these two makings that do not reach the standard are even less than half of the price. Some plastic cosmetic tube manufacturers use them or mix them with new ingredients to cut costs. These plastic cosmetic tube if the circulation of cosmetics, skin care products and other packaging areas, direct contact with cosmetics, then the harm to people is greater. It also creates an unfair competition for manufacturers of plastic cosmetic tubes that use new materials, and the environmental problems associated with producing these secondary materials.

The quality standards of plastic cosmetic tube are as follows:

1) Wholesale Cosmetic Tube system. The audit of cosmetic tube suppliers has become an indispensable and important link in the procurement of cream plastic cosmetic tube. Through the audit, the software and hardware facilities, technical equipment and comprehensive quality level of the factory can be evaluated correctly.

(2) the sealing and steam permeability of the cosmetic tube body and cover. Sealing and water vapor permeability are two important technical indicators of cream plastic cosmetic tube, they play an important role in the stability of the packaged product.

(3) Cream plastic cosmetic tube product quality standard. The standard of cosmetic Tube can be used to determine the quality of a product.

At present, plastic cosmetic tube shapes are round, square, oval and so on. The usage of circular cosmetic tube body is larger, which is characterized by more uniform wall thickness, higher ability to absorb impact energy, lower production cost, but low utilization rate of storage or transportation area. Square or rectangular cosmetic tube body storage area of high utilization, good stability, but more prone to bulge phenomenon.

The specifications and sizes of plastic cosmetic tubes have not been clearly and uniformly stipulated at present, but are usually determined according to the needs of users and the nature of cosmetics. Plastic cosmetic tube capacity in addition to the nominal capacity, there is a full capacity, it is larger than the nominal capacity, specific requirements depending on the diameter of the cosmetic tube mouth and the height of the cosmetic tube. The following wholesale Cosmetic Tube manufacturer takes small and medium-sized plastic cosmetic tube as an example, and analyzes its structural characteristics from the plastic cosmetic tube mouth, cosmetic tube neck, cosmetic tube shoulder, cosmetic tube body and cosmetic tube bottom.

Plastic cosmetic tube in cosmetic tube factory is mainly made of polyethylene or polypropylene and other materials and added a variety of solvents. There are many ways to make polyethylene, and one of the most common is to polymerize ethylene at 200-300 ℃ and 1,000-2,000 atmospheres. In polyethylene, there is no doping. The polyethylene density that makes so is low, quality of a material is soft, to sunshine, air, moisture and chemical reagent, have taller stability, do not need to add stabilizing agent, plasticizer so, and stabilizing agent and plasticizer are mostly poisonous or have extremely poisonous. Cosmetic tube is mostly plastic products, polyethylene, polypropylene these two materials clean no taste, used to fill drinks and other very stable to the human body. But polyethylene once subjected to high temperature or acid corrosion will slowly dissolve, and release solvents, will cause harm to the human body. Plastic cosmetic tube can be melted and spun, dissolved to make unsaturated resin, or re-granulation, but if the transparent products are made again, it is easy to find poor transparency and poor light transmission particles. Polyethylene has no smell, clean, feel like wax, has excellent low temperature resistance (low temperature can reach -70 ~ -100℃), good chemical stability, can withstand the erosion of most acid and alkali (not resistant to oxidizing acid), insoluble in general solvents at room temperature, small water absorption, excellent electrical insulation performance. But polyethylene for environmental stress (chemical and mechanical action) is very sensitive, heat aging poor. The properties of polyethylene vary from species to species, mainly depending on molecular structure and density.

There are a lot of plastic cosmetic tubes on the market that are recycled, reprocessed and put back on the market. If the wholesale Cosmetic Tube manufacturer is not careful, it will not distinguish whether the quality is bad or harmful to human health. The so-called secondary material production plastic cosmetic tube, is some plastic cosmetic tube produced by raw materials made of waste plastic without strict recycling and cleaning. But if you look closely, the Wholesale Cosmetic Tube manufacturer sometimes finds a poor gloss or impurity in a cosmetic tube, that's right, you're looking at a cosmetic tube made from secondary material.
