Introduction to Plastic Bottles of Cosmetic Packaging Material Knowledge

Plastic bottles are mainly made of materials such as polyethylene or polypropylene and added with a variety of organic solvents. Plastic bottles are widely used polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, and after adding corresponding organic solvents, after high temperature heating, they are blow molded, extruded, or injection molded through plastic molds Plastic container.

Introduction of plastic bottles for cosmetic packaging materials

1. The material of cosmetic plastic bottle is usually PP, PE, K material, AS, ABS, acrylic, PET, etc.

2. Generally used in cosmetics containers with thicker walls, cream bottles, bottle caps, stoppers, gaskets, pump heads, and dust covers are injection molded; PET blow molding is two-step molding, tube embryos are injection molding, and the finished product is packaged For blowing. Others, such as lotion bottles and washing bottles with thin container walls, are blown bottles.

3. The 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, and is widely used in gel water. The bottle mouth is generally standard 16#, 18#, 22#, 24# caliber, which can be used with a pump head.

4. Acrylic is made of injection molding bottle, which has poor chemical resistance. Generally, it cannot be directly filled with paste. It needs to be blocked by an inner liner. The filling is not easy to be too full to prevent the paste from entering between the liner and the acrylic bottle to avoid cracks. , Packaging requirements are high during transportation. It looks particularly obvious after scratches, has high permeability, and the sensory upper wall is very thick, but the price is quite expensive.

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

6. Mold development costs: blowing molds are 1,500 yuan-4,000 yuan, injection molds are 8,000 yuan-20,000 yuan, molds made of stainless steel are more expensive than alloy materials, but they are durable. Several molds can be produced at a time. The demand for production volume, if the production volume is large, you can choose a mold with four or six molds, and the customer can decide by himself.

7. The order quantity is generally 30,000-10,000, and the color can be customized. Usually the primary color is frosted and magnetic white, or the pearl powder effect is added. Although the bottle and cap are matched with the same color master, sometimes it is due to the bottle and cap. The materials used are different, and the colors displayed are somewhat different.

8. The screen printing has ordinary ink and UV ink. UV ink has good effect, gloss and three-dimensional effect. You should make a plate to confirm the color during production. The effect of screen printing on different materials will be different.

9. The processing technology of bronzing and silver bronzing is different from that of printing gold powder and silver powder. Hard materials and smooth surfaces are more suitable for bronzing and silver bronzing. The soft surface is not good for bronzing and is easy to fall off. The gloss of bronzing silver Degree is better than printing gold and silver.

10. Bottle caps are generally equipped with inner gaskets, pull caps, and inner plugs. Very few are equipped with small spoons or droppers. This is mainly due to its sealing and ease of use.

11. The production cycle is relatively moderate, about 15 days. The silk-screened cylindrical bottle is calculated as a single color, and the flat bottle or special-shaped bottle is calculated as two-color or multi-color. Usually, the first silk-screening fee or fixture fee is charged. The unit price is generally 0.1 yuan/color order to 0.15 yuan/color order, the screen version is 100 yuan-200 yuan/model, and the fixture is about 50 yuan/piece.
