Plastic bottles are usually made of PP, PE, K material, AS, abs, acrylic, PET, etc. All plastic bottles used for cosmetic packaging materials are divided into PP, PE, K materials, AS, ABS, acrylic, PET, etc. The PET material is used for cosmetic packaging plastic bottle molding, tube embryo injection molding, and bottle blowing product packaging.
Acrylic radiant bottles have poor chemical resistance. Generally, they cannot be placed and pasted directly. They should be equipped with spacers to prevent them from being too full to prevent sticking between the liner and the acrylic bottle to facilitate transportation and packaging. The scratches look smaller, the permeability is high, and the wall feels super thick, but it is quite expensive.
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 and can be equipped Use on the pump head.
Acrylic is made of injection-molded bottle, which has poor chemical resistance. Generally, it cannot be directly filled with paste. It needs to be blocked by an inner tank. The filling is not easy to be too full to prevent the paste from entering between the inner tank and the acrylic bottle to avoid occurrence Cracking, high packaging requirements during transportation, because it looks particularly obvious after scratches, has high permeability, and the sensory upper wall is very thick, but the price is quite expensive.
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.
