Polyethylene Terephthalate
PET
Polyethylene Terephthalate
(PET, PETE or polyester) is commonly used for carbonated beverages, water bottles and many food products. PET provides very good alcohol and essential oil barrier properties, generally good chemical resistance (although acetone’s and ketones will attack PET), a high degree of impact resistance and tensile strength. The orienting process serves to improve gas and moisture barrier properties and impact strength. This material does not provide resistance to very high temperature applications—max. temp. 200 °F (93 °C).PET
