Plastic Bottles Are Divided Into Various Materials Of Plastic

Common cosmetic packaging materials are plastic bottles(See more products), glass bottles, hoses and so on, the packaging materials of different materials have different characteristics, suitable for different texture and composition of cosmetics.Today we are going to take a closer look at plastic bottles

Plastic bottles: Plastic bottles are made of a variety of materials, including PET (polyethylene terephthalate), PP (polypropylene), PE (polyethylene), AS (styrene-acrylonitrile copolymer), acrylic, etc.

PET material: PET material transparency is high, the bottle body is soft, can be concave but harder than PP.PET material is environmentally friendly material, with high barrier, light weight, non-shattering characteristics, chemical resistance, strong transparency, can be made into pearl, color, magnetic white, transparent, widely used in gel water.Plastic bottles made of PET material The mouth of the bottle is generally standard 16#, 18#, 22#, 24# caliber, which can be used with pump head.

PP: Plastic bottles made of PP material are softer than PET, easier to pinch, transparency is worse than PET, so some opaque shampoo bottles are more commonly used (easy to squeeze).

PE: Plastic bottles made of PE material is almost opaque and not as smooth as PET.PP and PE materials are similar. They both belong to environmental protection materials, so they can directly contact with cosmetics and food materials. These two materials have a white visual appearance and a certain transparency, which are basically used in the filling of organic skin care products.

Acrylic: Thick and hard, the most like glass is acrylic.Acrylic material for plastic bottle, chemical resistance is poorer, generally cannot directly paste, need to match the tank, filling not too full, prevent the paste into the bladder and acrylic bottle, lest produce cracks, transport packaging of the demand is higher, because of the cut after look particularly evident, high permeability, sensory on wall thickness, the price is more expensive.

AS: Its hardness is not high, the material is brittle and transparent, which can directly contact with cosmetics and food materials. It is generally used AS the body of emulsion plastic bottle vacuum bottle.
