Plastics are also divided into many kinds of materials. Plastic bottles can be seen everywhere in our lives. So what are the materials of expensive plastic bottles for skin care products used on the face?
The material of plastic bottles is usually PP, PE, AS, ABS, Acrylic, PET, etc. Usually used in cosmetics containers with thicker walls, cream bottles, caps, stoppers, gaskets, pump heads, and dust caps are injection molding; PET blow molding is two-step molding, tube embryos are injection molding, and the finished packaging is blow molding. bottle. Others, such as emulsion bottles and washing bottles with thin container walls, are blown bottles. PET material PET material is an environmentally friendly material with high barrier properties, light weight, non-breaking characteristics, chemical resistance, and strong transparency. It can be made into pearlescent, colored, magnetic white, and transparent. It is widely used in gel water.
Acrylic material is an injection-molded bottle, which has poor chemical resistance. Generally, it cannot be directly filled with paste. It needs to be equipped with an inner tank to block it. The filling is not easy to be too full to prevent the paste from entering the inner tank and the acrylic bottle. In order to avoid cracks, the packaging requirements are high during transportation. It looks particularly obvious after scratching, has high permeability, and the sensory upper wall is extraordinarily thick, but the price is quite expensive.
AS, ABSAS, ABS: The transparency of AS is better than that of ABS, and the toughness is better. Usually the primary color frosted and magnetic white are the main ones, or the pearl powder effect is added. Although the bottle and cap are matched with the same color masterbatch, sometimes the color of the bottle and cap is different because of the difference in color.
UV ink screen printing has ordinary ink and UV ink. UV ink has better effect, gloss and three-dimensional effect. It should be printed to confirm the color during production. The effect of screen printing on different materials will be different.
There are differences in the effect of hot stamping and silver hot stamping on gold powder and silver powder. Hard materials and smooth surfaces are more suitable for hot stamping and silver hot stamping, while soft surfaces have poor hot stamping effects and are easy to fall off.
