These containers can prevent oxygen from entering and keep the food unchanged for a more extended period. Multilayer containers and bottles can also be made using preforms. It will then be shaped as desired with high-pressure air. It is enough to heat the Preform’s body to about 100 degrees Celsius and put it in the mold.

This small volume contributes a lot to environmental measures and reduces costs.Īnother advantage of Preform is that it can be used to produce bottles and containers with various designs. It is possible to carry 300,000 to 400,000 preforms with a 10-ton truck. Although the preform volume depends on the shape of the final bottle, there is a volume difference of about 1/5 to 1/10 between the Preform and the final product. One of the advantages of Preform is its small volume. In the second stage, the PET preform hollow tubes are placed in a unique mold and turned into different containers and bottles. The size of the mouth of the PET preform produced at this stage will not change after the production of the bottle, and its size is the same as the final size of the mouth of the bottle. This long tube is the same as the PET preform. In the first stage, the PET becomes a long tube similar to a laboratory tube. Therefore, the production of plastic bottles with PET raw material is done in two stages: Therefore it is not possible to produce containers and plastic bottles of PET preform by extrusion of melt and blowing polymer in the mold. These are the favorable properties of PET that have led to using this material as a suitable material in the plastics industry.Īnother unique feature of PET is that this material in the molten state, unlike other raw materials for plastic production, lacks sufficient strength. Some of these features are transparency, lightness, high strength, optimal creep properties, low flavor absorption, high chemical resistance, beautiful appearance, more accessible access, and low price. Some of these materials are polyvinyl chloride or PVC, polyethylene or PE, polyethylene terephthalate or PET, etc.Īmong these materials, PET has its characteristics. Many of the bottles are made from PET preform.ĭifferent types of materials are used to make plastic bottles.

The Preform is an intermediate product that Preform can convert into a variety of bottles.
