Cosmetic packaging - plastic type | NAMEI
Plastic packaging materials are commonly used in cosmetics, and plastic packaging materials include: PP, PE, PS, PET, PETG, PVC, ABS, acrylic and so on.
1. PP
PP material is polymer polypropylene, plastic is a polymer compound, non-toxic, harmless, no odor, better heat resistance, cold resistance is also good, chemical stability is very good, encounter strong acid and alkali chemical properties are not easy to change, more environmentally friendly.
Features: milky white translucent, lubrication, no slippiness; PP material is softer than PET, easier to pinch, and less transparent than PET.
How to color PP material: The color masterbatch produced by a special manufacturer, (a particle with a high color concentration composed of coloring agent, carrier resin, dispersant) it has a good color effect, and the color masterbatch is directly added to the product in the production process of PP plastic, and it can enter the next process normally after mixing, and the product will have color.
Makeup application: liquid eyeliner, liquid eyebrow pencil, nail polish pen, teeth pencil
2. PE
PE: polyethylene. The material is basically opaque, the material is a little softer, and it's not as smooth as PET.
Cosmetic applications: hose, lotion bottle, bottle cap, etc.
3. PET
PET is polyethylene terephthalate, a thermoplastic polyester, the surface is relatively smooth and shiny, can resist friction, and dimensional stability is good, high hardness, but not heat resistant water immersion, nor alkali resistance. The material is environmentally friendly, with high barrier property, light weight, non-breakable characteristics, chemical resistance, strong transparency, can be made into pearlescent, colored, magnetic white, transparent, widely used in gel water.
Features: PET transparency is high, the bottle body has softness, can pinch concave but harder than PP.
4. PETG
PETG transparency is better than PET, but it is not commonly used in China, the cost is high, the waste is high, and the material is not recyclable. PETG is used for all kinds of permanent daily necessities, such as cosmetics bottles, perfume bottles, medicine packaging containers and so on. Compared with PET, PETG has higher transparency, better chemical resistance, better oil resistance and better weather (yellowing) resistance than PET. The purchase cost of PETG is 2-3 times that of PET.
5. ABS
ABS: belongs to the engineering plastic, not environmentally friendly, high hardness, can not directly contact with cosmetics, food, in the acrylic cosmetic packaging material is generally the inner cover, shoulder cover material. The color is yellowish or cream white.
It is important to note that if the ABS cladding material will directly contact the material body, please note that the material body must not contain alkane lubricating oil, because it will cause the ABS amorphous zone to absorb swelling, brittle, crack.
Makeup application: Eyebrow pencil, glue pen
6. Acrylics
Acrylics: Thick and hard, the most glass-like acrylic.
Acrylic material for injection molding bottle, poor chemical resistance, generally can not be directly loaded paste, need to match the liner barrier, filling is not easy to be too full, prevent the paste into the liner and acrylic bottle between, so as to avoid cracking, transportation packaging requirements are higher, because of scratches look particularly obvious, high permeability, the perception of the wall is thick, but the price is quite expensive.
Second, pipe process
Color:
1, can customize the color, usually do the primary color scrub and magnetic white, or add pearlite powder effect. Although the bottle and the lid are matched with the same color masterbatch, sometimes the color is different due to the different material used by the bottle and the lid.
2, PP and ABS material bottle body with more solid color, PETG material and acrylic bottle multi-transparent color, clear sense, acrylic bottle wall multi-spray color, can refract light, good effect.
Printing: screen printing has ordinary ink and UV ink, UV ink effect is better, luster and three-dimensional, in the production should first print to confirm the color, in different materials of screen printing effect will be different.
Hot stamping silver: hot stamping, hot silver and other processing technology and printing gold powder, silver powder effect is different, hard material and smooth surface is more suitable for hot stamping, hot silver, soft surface hot stamping effect is not good, easy to fall off, hot stamping silver gloss is better than printing gold printing silver.
Third, mold cost, order quantity, production cycle
Mold development costs: injection mold for 80,000 yuan - 200,000 yuan range, mold stainless steel materials than alloy materials are more expensive, but durable, mold out of a few, see the demand for production, such as production is larger, you can choose a four or a six mold, customers can decide.
Order quantity: more than 12 thousand
Production cycle: more moderate, about 30 days cycle.
