Something About Plastic Bottles

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

     2.Usually used for cosmetic container wall thick cream bottles, caps, corks, 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 16mm, 18mm, 22mm, 24mm 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 be equipped with a liner barrier, filling is not easy too full to prevent the cream into the liner and acrylic bottle between, so as not to crack, the transportation of 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.Mold development costs: blowing mold for $250 - $400, injection mold for $1400 - $3500 ranging, mold with stainless steel materials than with alloy materials to expensive, but durable, mold once out of several, depending on the demand for production volume, such as a larger production volume, you can choose a four or one out of six molds.

  7.Can customize the color, usually do the original color frosted and magnetic white, or add pearl 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, internal plug, very few with a small spoon or dropper, which is mainly to consider its tightness and ease of use.

  11.The production cycle is more 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, usually to charge the first screen printing screen fee or jig fee.

  It's all different materials, the main difference between knowing these.

PET: PET high transparency, the bottle has a softness, can pinch concave but a little harder than PP.


PP: PP bottle is softer than PET, easier to pinch, transparency is worse than PET, so some opaque shampoo bottles are more commonly used (squeeze up convenient).


PE: the bottle is basically opaque, and not so smooth as PET.


Acrylics Yak: and thick and hard, most like glass is acrylic.
