PET (Polyethylene terephthalate ) is a general-purpose thermoplastic in the polyester family. PET plastic is lightweight, strong, and impact-resistant. It is often used in food processing machinery due to its low moisture absorption, low thermal expansion, and chemical-resistant properties.

Lower impact strength than PBT Lower moldability than PBT, due to its slow crystallization rate Affected by boiling water Attacked by alkalis and strong bases Attacked at high temperatures (>60°C) by ketones, aromatic and chlorinated hydrocarbons, and diluted acids and bases Poor burning behavior.

● Light specific gravity: The specific gravity of A-PET is 1.33 which is 3.7% lower than that of PVC.
● High strength: The strength of A-PET sheet is more than 20% higher than that of PVC sheet, and it has better low-temperature impact resistance. It can withstand -40°C without brittleness, so it is usually 10% thinner than the sheet to replace PVC .
● Good folding resistance: A-PET sheet will not show self-cracking creases like PVC, and it is more suitable for surface decoration such as documents.
● A-PET sheet has high transparency (PVC sheet is blueish), especially gloss is better than PVC sheet, and is more suitable for exquisite packaging.

Polyethylene Terephthalate is used in several packaging applications as mentioned below: Because Polyethylene Terephthalate is an excellent water and moisture barrier material, plastic bottles made from PET are widely used for mineral water and carbonated soft drinks. Its high mechanical strength, makes Polyethylene Terephthalate films ideal for use in tape applications. Non-oriented PET sheet can be thermoformed to make packaging trays and blisters. Its chemical inertness, together with other physical properties, has made it particularly suitable for food packaging applications Other packaging applications include rigid cosmetic jars, microwavable containers, transparent films, etc.
