The material of plastic bottles is usually PP, PE, K-material, AS, ABS, acrylic, PET, etc.
2. Incosol is usually used for cosmetic containers with thicker wall, such as cream bottles, caps, stoppers, liners, pump heads, dust covers, which are injection molding; PET blow molding is a two-step process, with the tube molding being injection molding, and the finished product packaging being blow molding. Other containers with thinner walls, such as milk bottles and washing bottles, are blow molded.
3. PET material is an eco-friendly material with high barrier properties, light weight, non-fragility, excellent chemical resistance, and extremely high transparency. It can be made into luster, colored, matte white, and transparent, and is widely used in the application of gel water. The mouth of the bottle is usually standard 16#, 18#, 22#, or 24# diameter, which can be paired with a pump head for use.
4. Acrylic material is used for injection molding bottles, which have poor resistance to chemicals. Generally, they cannot be directly used to contain pastes, and an inner liner is required to prevent contamination. It is not recommended to fill the bottles too full, to prevent the paste from entering between the inner liner and the acrylic bottle, which could cause cracking. The packaging requirements during transportation are relatively high, as any scratches are particularly noticeable. Acrylic bottles have high transparency and appear to have a particularly thick wall, but they are quite expensive.
5. AS and ABS: AS has better transparency and better toughness than ABS.
