Cosmetic packaging material knowledge of plastic bottles

Plastic bottles are mainly made of polyethylene or polypropylene and a variety of organic solvents. Plastic bottles are widely used polyester (PET), polyethylene (PE), and polypropylene (PP) as raw materials, adding the corresponding organic solvent, after high-temperature heating, through the plastic mold through blow molding, extrusion blowing, or injection molding plastic containers.

The generalized plastic bottle is mainly used for beverages, food, pickles, cosmetics, agricultural and veterinary drugs and other liquid or solid disposable plastic packaging containers. Plastic bottles are not easy to break, low cost, high transparency, food-grade raw materials and so on.

Cosmetic packaging materials of plastic bottles

1. cosmetic plastic bottles are usually made of PP, PE, K, AS, ABS, acrylic, PET and so on.

2. usually used for cosmetics container wall thick cream bottles, caps, stoppers, gaskets, pump head, dust cover for injection molding; PET blowing bottle is two-step molding, tube embryo is injection molding, finished product packaging is blowing bottle. Other such as thin container wall emulsion bottles, washing bottles for blowing bottles.

3. PET material is environmental protection material, with high barriers, light weight, non-breaking characteristics, chemical resistance, strong transparency, can be made into pearl, color, magnetic white, transparent, and widely used in gel water. The mouth of the bottle is generally standard 16#, 18#, 22#, 24# caliber, which can be used with pump head.

4. 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, but the price is quite expensive.

5. AS, ABS: AS transparency is better than ABS, and toughness is better.

6. the order quantity is generally 3 thousand - 10 thousand, can customize the color, usually do primary color grinding and magnetic white, or add pearl powder effect, although the bottle and cover with the same color master, but sometimes because the bottle and cover with the material is not the same, the performance of the color is some difference.

7. screen printing with ordinary ink and UV ink, UV ink effect is better, gloss and three-dimensional, in production should be the first version to confirm the color, screen printing effect in different materials will be different.
