Detail Specifications / Descriptions

P.E.T material has characteristics of good chemical effect tolerance, nice transparency, and satisfied the food safety grade standard, which has been used in many products, such as mineral bottle, fruit juice bottle, carbonate drink bottle..., etc. If it is used for cosmetic containers, it is better to use P.E.T.G. material since P.E.T.G has even better chemical effect tolerance. unlike for acrylic container, which the internal must fix with PP material container.
The biggest issue for P.E.T material is that it absorbs humidity from the air, therefore, one must dehumidify the material to be below 0.05%. Otherwise, the product will become easily destroyable with also crystal white finishing surface. Based on this issue, a P.E.T injection machine must come with a complete set of dehumidifier, which dries the air between -29 to -40 degree, and for dryer machine it's about 180°C. Furthermore, in order to prevent the mold gets sweaty, the mold must have dew preventing equipment, which normally uses cool air to blow, but sometimes using dry/hot air process system. The workshop should also include air condition and dehumidifier.
