Molecular structure

There are basically two types of plastic: the first is a linear structure, a polymer compound having such a structure is called a linear polymer compound; the second body structure, a polymer cosmetic gift box  compound having such a structure is called a high figure molecular compounds. Some polymer having a branched chain, a branched polymer known as belonging to the linear structure. Although some high molecular crosslinking between molecules, but less cross-linking, called reticular structure, the body structure belongs.
Two different structures exhibit wholesale cosmetic bags two opposite properties. Linear structure, heat can be melted, the smaller the hardness and brittleness characteristics. Body structure hardness and brittleness. Polymer plastic then two structures are, by the linear polymer is made ​​of thermoplastic polymer made ​​by the body is a thermosetting plastic.

The molding material of the container

The most common forming methods are: injection molding, blow molding, injection stretch blow molding.
2 container molding methods:  wholesale cosmetic bags  molding, blow molding, injection stretch blow molding.
3 surface decoration and post-processing effects: a container after surface treatment can printing, hot stamping, labeling (IML also)
4 Scope of application: inner timber with cosmetics good compatibility. Suitable cover, inside cover, liner, sealing film, plastic plugs, shampoo bottles, etc. But do not solvent-based nail polish, to water containers and other products.
Injection molding  small cosmetic bag  structure design must focus on the appearance of plastic products will affect the quality of the content: gate location, type of position, the wall thickness.

Cosmetic containers

The most commonly used plastic  cosmetic containers wholesale  containers from the texture of the material can be divided into two categories: hard and soft materials materials.
Typical materials are soft polyethylene PE, PP polypropylene.
The apparent post-processing features: PE polyethylene translucent white waxy material, soft and tough, a little can done, the material is lighter than water, non-toxic. Can color, but the color vividness poor. PP polypropylene transparent or translucent material, excellent resistance to winding performance. After the material better color brightness color. Shen Xiaoming Jahwa United Co., Ltd.
Typical rigid materials are ABS acrylonitrile - butadiene - styrene copolymer, PMMA polymethyl methacrylate, etc.

Plastic glass cosmetic bottles

With the rapid development of modern industry and public opinion continue to enhance environmental protection , paper packaging applications more widely in the commodity , demand is growing . Metallized paper is one of them . Metallized paper mainly consists of paper , aluminum layer and the coating composition, due to good gloss and smoothness , flexibility, sprayed aluminum layer fastness, beautiful environment. cosmetic jarmajor consumer groups are women , cosmetics packaging is attractive to a large extent influence the minds of women status in the cosmetics as well as their preference for a particular brand . Colorful transparent vacuum aluminum printing inks, can revealing splendid noble metallic luster , while giving a psychological hint : use cosmetics after this I could be brilliant, and easy printing. Easy to carry laser holographic vacuum aluminum handle , with good security role. According to the different needs of cosmetic packaging printed on a laser flash LOCO or specific pretty patterns, both beautiful and fresh and easy to identify , but also to discourage counterfeiting . But for now the whole cosmetics market, plastic and glass packaging materials still dominated .
