| 摘要 |
The invention relates to a method of laminating a sheet material, especially a laminating film material, onto a substrate with a hot melt adhesive, by in-line coating said hot melt adhesive onto said sheet material and/or said substrate, at or above the lowest processing temperature of said hot melt, and laminating the sheet material onto said substrate, said hot melt adhesive comprising a thermoplastic polymer selected from copolymers of olefins, especially ethylene, and (meth-)acrylic acid; copolymers of olefins, especially ethylene, and (meth-)acrylic acid derivatives, especially (meth-)acrylic acid esters; copolymers of olefins, especially ethylene, and vinylic compounds, especially vinyl carboxylates such as vinyl acetate; poly- alpha -olefins, especially atactic poly- alpha -olefins (APAO's); thermoplastic rubbers; metallocene-catalyzed polymers, especially based on ethylene and/or propylene; ionomers and corresponding copolymers; and mixtures thereof. The invention further relates to a hot melt laminating adhesive as above indicated, suitable for in-line coating in an in-line lamination process.
