What is PET Preform
PET double wall bottle and jar are made by PET double wall Preform. PET preform is a raw material used to make PET plastic bottles/jars. PET, short for polyethylene terephthalate, is a common plastic material with excellent transparency, heat resistance and chemical resistance. PET preform are usually in the shape of a tube, and their inner diameter and wall thickness can be adjusted according to needs.
The production process of PET preform usually includes the following steps: first, the PET raw material is heated to a molten state, and then the molten PET raw material is extruded into a tube shape through an extruder. Next, the extruded tubular PET is quickly cooled through a cooling device to solidify it. Finally, the cured PET preform are cut to the required length for further processing into PET plastic bottles/jar.
PET preform embryos have many advantages, such as: First, the PET material has good transparency, so that the made PET plastic bottle and jar can clearly show its internal contents. Secondly, PET material has high heat resistance and can withstand the high-temperature filling process. In addition, PET material also has good chemical resistance and can resist the erosion of chemicals such as acids and alkalis.
Our PET preform are widely used in plastic bottle and jar packaging in food, beverage, cosmetics, pharmaceutical and other industries. Its production cost is relatively low, its production efficiency is high, and it meets environmental protection requirements. Therefore, PET preform have an important position and application prospects in the plastic bottle and jar packaging industry.
