  • Process for producing thermoformable polypropylene films and sheets
    Patent number: 5209892
    Abstract: A process for thermoforming thermo-plastics including a random copolymer of polypropylene and polyethylene. The process including stretching in at least one direction, a film or sheet containing polypropylene and polyethylene random copolymer to partially orient the sheet sufficiently as to reduce sag during thermoforming and thermoforming the stretched sheet.

  • Coextruded heat sealable laminar thermoplastic films
    Patent number: 4197150
    Abstract: Laminar thermoplastic films are provided which exhibit improved heat seal strengths as well as heat seal temperature ranges. The laminates comprise a predominantly propylene-based polymer substrate or core, the propylene core layer being coated with continuous skins, the skins being fabricated from ethylene based resin with a density of less than 0.939.

  • Packaging film with improved heat sealability
    Patent number: 4125662
    Abstract: A packaging film composition having an improved heat seal range. The film comprises a core, which is preferably propylene homopolymer or copolymer but which may be a blend of polypropylene with any other compatible polymer, such core being coated on one or both sides with butene-1 homopolymer or with a copolymer of butene-1 with ethylene.
