Plastic bottles were mainly made of polyethylene or polypropylene and other organic solvents. Plastic bottles are widely used as raw materials, such as polyester (PET), polyethylene (PE), and polypropylene (PP). After adding corresponding organic solvents, the plastic containers are blown, extruded and molded through plastic moulds after high temperature heating. It is mainly used for liquid or solid disposable plastic packaging containers for beverages, food and cosmetics. Plastic bottle has the characteristics of not broken, low cost, high transparency, food grade raw material and so on.

Two. The main material of cosmetic plastic bottle

Plastic bottles are usually made of PP, PE, K, AS, ABS, acrylic, PET and so on. PET is a kind of environmental protection material. It has high barrier property, light quality, unbreakable property, resistance to chemical resistance and strong transparency. It can be made into pearlite, colored, magnetic white and transparent, and is widely used in gel water. The bottle for the general standard of 16#, 18#, 22#, 24# diameter, can be equipped with a pump head. The transparency of AS and ABS:AS is better than ABS, and the toughness is better. Acrylic material for injection bottle, poor chemical resistance, generally can not directly install the paste, need to match the internal gallbladder barrier, filling not easily too full, prevent the ointment into the inner gallbladder and acrylic bottle, so as to avoid cracking, the transportation in the high packaging requirements, because of the scratch, it looks particularly obvious, high permeability, the sense of the thickness of the wall thickness But the price is quite expensive.

Three. Category and technology of cosmetic plastic bottle

1. The cream bottle, cap, bottle plug, gasket, pump head and dust cover for the thick wall of cosmetics container are injection molding. The PET blowing bottle is two step molding, the tube embryo is injection molding, and the finished product is packed into a bottle. Others, such as latex bottle with thin container wall and washing bottle, are blowing bottles.

2. hot gold, hot silver and other processing technology is different from the effect of gold powder and silver powder. Hard material and smooth surface are more suitable for stamping gold and iron. The soft surface is not good, easy to fall off, and the glossiness of the hot gold and silver is better than the Indo gold silver. The screen is transparent, the color is transparent, the gold is hot, and the process of hot silver is made out of the sun. The effect of the graphic and the text is transparent, and the background color is the color. The proportion of characters and patterns should not be too small or too small, otherwise they will not print.

3, the bottle cap is usually equipped with an inner gasket, a lid and an inner stopper, and a few are equipped with small spoons or dropper, which is mainly concerned with its tightness and convenience.
