Cosmetic packaging materials knowledge of plastic bottle introduction

Plastic bottles are mainly made of materials such as polyethylene or polypropylene with the addition of a variety of organic solvents. Plastic bottles are widely used polyester (PET), polyethylene (PE), polypropylene (PP) as raw materials, after adding the corresponding organic solvents, after high temperature heating, through the plastic mold after blow molding, extrusion, or injection molding of plastic containers.

General plastic bottles are mainly used for beverage, food, cosmetics, agricultural and veterinary medicine and other liquid or solid disposable plastic packaging containers. Plastic bottles have the characteristics of not easy to break, low cost, high transparency, food-grade raw materials, etc.

Introduction of plastic bottles for cosmetic packaging materials

1.cosmetic plastic bottles are usually made of PP, PE, AS, ABS, acrylic, PET, etc.

2.Usually used for cosmetic containers with thick walls cream bottles, caps, stoppers, gaskets, pump heads, dust covers for injection molding; PET blowing bottles for two-step molding, tube embryo for injection molding, finished packaging for blowing bottles. Other bottles such as lotion bottles and washing bottles with thin container walls are blow bottles.

3. PET material is environmentally friendly material, with high barrier, light weight, non-shattering characteristics, chemical resistance, transparency is very strong, can be made into pearlescent, colored, magnetic white, transparent, widely used in containing gel water. Bottle mouth is generally standard 16 #, 18 #, 22 #, 24 # caliber, can be used with the pump head.

4.acrylic material for injection molding bottles, chemical resistance is poor, generally can not be directly filled with cream, need to match the liner barrier, filling is not easy too full to prevent the cream into the liner and acrylic bottle between, so as not to crack, transportation in the packaging requirements are high, because the scratch looks particularly obvious, high permeability, the sense of the wall is particularly thick, but the price is quite expensive.

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

6.Mould development cost: blowing mould is 1500RMB-4000RMB, injection mould is 8000RMB-20000RMB, customers can decide by themselves.

7.Order quantity is generally 10,000, can be customized color, usually do the original color frosted and magnetic white, or add pearlescent powder effect, although the bottle and cover with the same color master, but sometimes due to the bottle and cover with different materials, the performance of the color some differences.

8.screen printing with ordinary ink and UV ink, UV ink effect is better, glossy and three-dimensional, in the production should first hit the plate to confirm the color, the screen printing effect in different materials will be different.

9. hot stamping, hot silver and other processing and printing gold powder, silver powder effect is different, hard material and smooth surface is more suitable for hot stamping, hot silver, soft surface stamping effect is not good, easy to fall off, hot gold silver gloss is better than the printing gold printing silver.

10. the cap is generally equipped with internal gaskets, pull the cap, the inner plug, very few with a small spoon or dropper, which is mainly to consider its tightness and ease of use.

11.production cycle is moderate, about 15 days cycle, screen printing cylindrical bottles for single-color calculation, flat bottles or shaped bottles by two-color or multi-color calculation.
