Cosmetic packaging materials are divided into several materials?
General plastic

Generally refers to plastics with large output, wide application, good formability and low price. There are five major varieties of general-purpose plastics, namely polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS) and acrylonitrile-butadiene-styrene copolymer (ABS).

20 engineering plastics

Generally speaking, it can bear a certain external force, has good mechanical properties, high and low temperature resistance, good dimensional stability, and can be used as engineering plastics, such as polyamide and polysulfone.

3. Special plastics

Generally refers to plastics with special functions that can be used in special applications such as aviation and aerospace. For example, fluoroplastics and silicones have outstanding special functions such as high temperature resistance and self-lubrication, and reinforced plastics and foams have special properties such as high strength and high cushioning properties. These plastics belong to the category of special plastics.

What is the material of the plastic bottle for cosmetics?
Generally there are PET plastic, PP plastic, PETG plastic. Ordinary cosmetics and detergent packaging containers are mostly made of high-density polyethylene. In order to meet the packaging requirements of different products, the materials used in plastic bottles are also increasingly enriched.

1. PET material is environmentally friendly material, it is polyethylene terephthalate, has high barrier property, light weight, non-breaking property, chemical resistance, strong transparency, can be made into pearlescent, colored, magnetic white, Transparent, widely used in the installation of gel water. The bottle mouth is generally standard 16#, 18#, 22#, 24# caliber, and can be used with the pump head.

2. The development of pp transparent packaging bottles is a hot spot in plastic bottle packaging at home and abroad in recent years. Highly transparent polypropylene container (PP plastic) with good transparency and gloss, and is very popular and popular.

3. PETG is polyethylene terephthalate-1,4-cyclohexanedimethanol ester. PETG is used in a variety of long-term daily necessities, such as cosmetic bottles, perfume bottles, pharmaceutical packaging containers and so on.

Ways to identify the safety of plastic containers:

The bottom of ordinary mineral water bottles is mostly "1-PET" (also known as "1-PETE"); the bottom of products containing shampoo, shower gel, laundry detergent and so on is marked "2-HDPE". In the plastic cup, the bottom of the bottle, the number "7" is written in the triangle with the arrow. At the same time, the reporter also found that there are some plastic bottles on the market, there is no logo at the bottom.

When PET is heat resistant to 70 ° C and is easily deformed, it will dissolve substances harmful to the human body. At the same time, it should not be exposed to the car, and should not be filled with alcohol or oil. It can be filled with normal temperature water in a short period of time, but it cannot be filled with high temperature water, and it is not suitable for acid and alkaline beverages.

PP polypropylene, which can be used to make microwave lunch boxes, is the only plastic box that can be placed in a microwave oven and can be reused. The plastic product marked with No. 6 is made of PS polystyrene. When the temperature is too high, it will release chemicals and cannot be used for strong acid and strong alkaline substances. No. 7 OTHER is made of other plastics. If such containers are damaged, they should be stopped because of the fine pits on the surface, which tend to hide bacteria.

When using a plastic container, be sure to look at the numbers marked in the triangle at the bottom of the bottle. Only understand the material properties before using it in a suitable environment. A triangle consisting of three arrows is usually printed on the bottom of the plastic bottle, with a number ranging from 1 to 7.
