<p>A printable thermoplastic multilayer laminate is a coextruded and multilayered laminate, and comprises a polyolefin sealing layer (1), a gas-barrier layer (4) and/or a resin material layer. The laminate has modulus of 4000 kg/cm2> or more at room temperature of 23[deg]C. The resin material layer has glass transition temperature of 70-150[deg]C, more preferably 70-100[deg]C, and tensile modulus of 1900 MPa or more.

The multilayer laminate has modulus of 4000 kg/cm2> or more at room temperature of 23[deg]C. The resin material layer has glass transition temperature of 70-150[deg]C, preferably 70-125[deg]C, and more preferably 70-100[deg]C, and tensile modulus of 1900 MPa or more evaluated according to ASTM D882 on a sheet (250 mu m). Independent claims are included for the following: (1) vacuum skin packaging process which involves using the multilayer laminate as top skin web; (2) vacuum skin package comprising a support, a product positioned on the support, and coextruded multilayer laminate covering the product, conforming to its shape and sealing to the support around periphery of the product.</p> |
