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.
