Compositions of polyethylene and ethylene/ethylacrylate copolymers for improved heat sealability

A polymer composition comprises a blend of a polyolefin, e.g polyethylene, and a copolymer of ethylene and ethyl acrylate of melt index 15 to 100. Optional ingredients are polyterpene resins, paraffin wax, hydrocarbon resins, rosin, oleamide, and/or acetylated monoglycerides. The compositions find a...

Beschreibung
Zusammenfassung:	A polymer composition comprises a blend of a polyolefin, e.g polyethylene, and a copolymer of ethylene and ethyl acrylate of melt index 15 to 100. Optional ingredients are polyterpene resins, paraffin wax, hydrocarbon resins, rosin, oleamide, and/or acetylated monoglycerides. The compositions find application as coated or laminated products, e.g. in the production of lenticulated pictures.ALSO:Substrates such as Kraft paper "Cellophane" (Registered Trade Mark), aluminium foil, cellulose acetate butyrate, polyesters, polyvinyl chloride, polyvinylidene chloride, polystyrene, acrylic resins, phenolic resins and polyolefins, may be coated with a blend of a polyolefin, e.g. polyethylene, and a copolymer of ethylene and ethyl acrylate of melt index 15 to 100. The products find application in heat sealing and in the production of lenticulated pictures.
