APPEEL™ 53021 is a modified ethylene vinyl acetate copolymer resin designed to function as a sealing layer for lidding applications. It is most often suggested to provide strong peelable seals to polypropylene, and moderate seals to polystyrene, polyester, PVC and is available in pellet form for use in conventional extrusion or coextrusion equipment designed to process polyethylene resins.

Uses

• Lidding Sealant

Applications

• Low temperature heat seal. APPEEL™ 53021 offers low temperature heat seals with adequate seal strength at 90oC.

• Heat sealability to various materials including PE, PP, PS, and Rigid PVC. APPEEL™ 53021 can also be sealed to paper, paperboard, woven fabrics, non-woven fabrics, wood and photographic papers.

• APPEEL™ 53021 allows a peelable seal from most plastic materials excluding PE.

• High transparency.

• APPEEL™ 53021 conforms to Code #20 of the Ministry of Health and Welfare Japan.

• APPEEL™ 53021 is used as a heat seal layer in lidding material for injection molded and vacuum molded plastic containers, especially HIPS and PS used in the packaging of yogurts, jams, butter and other food items.

Typical structures for this lidding would be:
OPP/PE/ APPEEL™ 53021
PET/PE/ APPEEL™ 53021
Over lacquer/Print/Foil/PE/ APPEEL™ 53021
Paper/PE/Foil/PE/ APPEEL™ 53021

APPEEL™ 53021 can also be used as a sealant in general flexible packaging. It provides low temperature seals for snacks and confectionery.
