1.PP
PP material is a polymer polypropylene, plastic is a polymer compound, non-toxic, harmless, odorless, heat resistance is relatively good, cold resistance is also good, chemical stability is very good, encounter strong acid strong alkali chemical properties are not easy to change.
Features
Milky white translucent, lubricated, no slippery feeling; PP bottle is softer than PET, easier to pinch, transparency is worse than PET, so some opaque shampoo bottles are more commonly used (convenient to squeeze up).
2.PE
PE: polyethylene. The material is basically opaque, the material will be softer and not as smooth as PET.
Cosmetic applications:tubes, lotion bottles, caps, etc.
3.PET
PET is polyethylene terephthalate, a thermoplastic polyester with a smooth and glossy surface, resistant to friction, good dimensional stability and high hardness, but not resistant to water immersion or alkali. It is an environmentally friendly material with high barrier properties, light weight, non-shattering properties, chemical resistance and excellent transparency, and can be made into pearlescent, coloured, magnetic white or transparent, and is widely used in jellies.
Features
PET has a high transparency, the bottle has a softness, can be pinched concave but harder than PP.
4. PETG
PETG is more transparent than PET, but it is not commonly used in China, has a high cost, high scrap, once formed, not recyclable material. The purchase cost is 2-3 times higher than PET.
5. AS
AS, also known as SAN, is a styrene acrylonitrile copolymer with higher impact strength and better heat resistance, oil resistance and chemical resistance than polystyrene (PS). It is not very hard, brittle (crisp sound when struck), good transparency, can be in direct contact with cosmetics, food, in ordinary lotion bottles, vacuum bottles are generally the material of the bottle, but also can be made of small capacity cream bottles. It has a transparent appearance. Cream bottles, powder cases, eye shadow cases.
6. ABS
ABS is an engineering plastic, not environmentally friendly, high hardness, can not be directly in contact with cosmetics, food, in acrylic cosmetic packaging materials are generally the material of the inner lid, shoulder cover. The colour is yellowish or milky white.
Note that if the ABS package will be in direct contact with the material, please note that the material must not contain alkane lubricants, because it will lead to ABS non-crystalline area absorption swelling, brittle, cracked.
7. Acrylics
Acrylic is thick and hard, most like glass.
Acrylic material for injection molding bottles, chemical resistance is poor, generally can not be directly filled with cream, need to match the liner barrier, filling is not easy too full, to prevent the cream into the liner and acrylic bottle between, so as not to crack, transportation in the packaging requirements are high, because the scratch looks particularly obvious, high permeability, the sense of the wall is particularly thick, but the price is quite expensive.
