Contains amides for slip / chill roll release, but less than in Appeel® 53070. Low temperature heat seal. Appeel® 53071 offers low temperature heat seals with adequate seal strength at 90C. Heat sealability to various materials including PE, PP, PS, and Rigid PVC. Appeel® 53071 can also be sealed to paper, paperboard, woven fabrics, non-woven fabrics, wood and photographic papers. Appeel® 53071 allows a peelable seal from most plastic materials excluding PE. High transparency. Boiling resistance. Appeel® 53071 endures boiling process, whose conditions are 90C / 30min.
