FEATURES OF PET
• Outstanding clarity
• Strong yet lightweight
• PET in its natural state is colourless and based on how it is processed can be semi-rigid
to rigid, and it is very lightweight. It makes a good gas and moisture barrier
• Excellent barrier properties especially for Modified Atmosphere Packaging
• Hygenic and safe for direct food contact
• Resistant to cracking
• Can be coloured or tinted
• Not temperature resistant as softens and deforms at 65-70°C, therefore PET cannot
be used for cooking
• Can be difficult to seal against unless specialist sealing film and/or
SharpSeal®
is used
