1.What is PET sheet?

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

2.What is advantages of PET?

It has higher strength and stiffness than PBT
It is very strong and lightweight & hence easy and efficient to transport
It is known for its good gas (oxygen, carbon dioxide) and moisture barrier properties
It exhibits excellent electrical insulating properties
PET has broad range of use temperature, from -60 to 130°C
As compared to PBT, it also has higher heat distortion temperature (HDT)
It has low gas permeability, in particularly with carbon dioxide
PET is suitable for transparent applications, when quenching during processing
PET doesn’t not break or fracture. It is practically shatter-resistant and hence, a suitable glass-replacement in some applications
It is recyclable and transparent to microwave radiation
PET is approved as safe for contact with foods and beverages by the FDA, Health Canada, EFSA & other health agencie

3.What is the disadvantages of PET?

Lower impact strength than PBT 
Lower moldability than PBT, due 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

4.What are the main applications of PET? 

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.
