1. Plastic bottles are usually made of PP, PE, K material, AS, ABS, acrylic, PET and so on.
2. For cosmetic containers with thicker wall cream bottles, caps, stoppers, gaskets, pump head, dust cover for injection moulding; PET blow molding is divided into two steps, the embryo tube for injection moulding, the finished product for blowing process. Other bottles such as thinner lotion bottles, washing bottles for blow moulding.
3.PET material is an environmentally friendly material, with high barrier, lightweight, non-crushing properties, chemical resistance, transparency is very strong, can be made into pearl, coloured, solid white, transparent, in the essence of water is widely used. Bottle neck is generally divided into 20/410, 24/410, 28/410, 32/410, can be used with the same neck pump sprayer.
4. acrylic material for injection moulding bottles, chemical resistance is poor, generally can not directly load cream, need to match the liner barrier, filling cream is not easy too full, to prevents the cream from seeping between the bottle and the liner, so as to avoid cracking, the transport of the packaging requirements of the higher, due to scratches look particularly obvious, high translucency, canisters are also heavier, and therefore the price is quite expensive.
5… AS, ABS is mostly used to make the bottle cap, or bottle shell, but AS transparency is better than ABS, and better toughness.
6. Mould development: moulds made of stainless steel are more expensive than those made of alloy materials, but durable, moulds once out of a few, depending on the demand of the production volume, such as production volume is large, you can choose one out of four cavity or one out of six cavity, the customer can decide for themselves.
7. Bottle MOQ is 1W, can be self-colour, usually do transparent and solid white mainly, or other frosted effect, bottle and cover with the same colour, but sometimes due to the bottle and cover with different materials, the performance of the colour is a little different.
8. Screen printing with ordinary ink and UV ink, UV ink effect is better, glossy and three-dimensional sense, in the production will be the first plate to confirm the colour, screen printing effect will be different in different materials.
9. Bottle caps are generally equipped with gaskets, hand-pulled gaskets, inner plugs, which is mainly to consider its sealing and ease of use.
10. The production cycle is moderate, about 25-30 days, screen printing cylindrical bottles for single-colour calculation, flat bottles or shaped bottles according to two-colour or multi-colour calculation.
