MULTI-LAYER FILM OR SHEET MATERIAL |
摘要 |
<p>The invention provides a multi-layer film or sheet material of thermoplastic resins having a high adhesive bonding strength between layers as well as excellent heat-sealability The multi-layer film or sheet material comprises a layer A formed of a resin composition composed of a polypropylenebased resin and a linear low-density ethylene .alpha.-olefin copolymer having specified density and a layer B formed of a polypropylene-based resin or a layer formed of a resin composition of a polypropylene-based resin and a lowcrystallinity .alpha.-olefin copolymer. The invention also provides a laminated film or sheet material comprising a base material, e.g. plastic film, paper, aluminum foil, etc., and the above defined multi-layer film or sheet material bonded together through an intermediate layer of an adhesive in such a manner that the layer A in the multilayer film or sheet material faces the base material.</p> |
