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
• The Polyethylene top layer enables easy sealing which has become
industry standard in the meat sector.
• The PE is a mutli-layered laminate to give the best possible sealing.
• The PE becomes soft at a lower temperature than PET which
enables the film to seal securely.
