How to choose plastic cosmetic packaging materials?

July 23,2022

Cosmetic packaging materials are divided into main containers and auxiliary materials
The main containers are usually: plastic bottles, glass bottles, hoses, vacuum bottles.
Auxiliary materials usually include: color box, box, middle box
At present, the materials of plastic bottles are usually PP, PE, AS, ABS, acrylic, PET, etc. How should customers choose the material of plastic bottles?

1. It is usually used for cream bottles, bottle caps, bottle stoppers, gaskets, pump heads and dust covers with thick walls in cosmetic containers. Injection molding; PET bottle blowing is two-step molding, tube blank is injection molding, and finished product packaging for blowing the bottle. Others, such as lotion bottles and washing bottles with thin container walls, are blowing bottles.
2. PET material is an environmentally friendly material, with high barrier properties, light weight, non-breaking properties, chemical resistance, and strong transparency. It can be made into pearlescent, colored, magnetic white, and transparent. The bottle mouth is generally standard 16#, 18#, 22#, 24# diameter, which can be used with a pump head.

3. AS, ABS: The transparency of AS is better than that of ABS, and the toughness is better.

4. The acrylic material is an injection-molded bottle, which has poor chemical resistance. Generally, the paste cannot be directly loaded. It needs to be equipped with an inner tank to block the filling. It is not easy to be too full to prevent the paste from entering between the inner tank and the acrylic bottle. In order to avoid cracks, the packaging requirements during transportation are relatively high, because it looks particularly obvious after scratches, has high permeability, and feels extra thick on the upper wall, but the price is quite expensive.

5. Bottle caps are generally equipped with inner gaskets, pull caps and inner plugs, and very few are equipped with spoons or droppers, which are mainly due to their tightness and convenience of use.
6. The screen printing film should have a negative film, the picture and text effect should be black, the background color should be transparent, the hot stamping and hot silver process should produce a positive film, the picture and text effect should be transparent, and the background color should be black. The proportion of text and patterns should not be too small or too thin, otherwise the effect will not be printed.

7. The processing technology of hot stamping and hot silver is different from that of printing gold powder and silver powder. Hard material and smooth surface are more suitable for hot stamping, hot silver and soft surface hot stamping.
The effect is not good, it is easy to fall off, and the gloss of bronzing silver is better than that of printing gold and silver.

8. There are ordinary ink and UV ink for silk screen printing. UV ink has better effect, glossy and three-dimensional effect. During production, you should make a plate to confirm the color. The screen printing effect of different materials will be different.
