Patent ID: 8163127

Claim:
A process for manufacturing a packaging material with two films ( 12 , 16 ) or foils bonded via an adhesive layer to form a multi-layer laminate ( 10 ) whereby the adhesive layer ( 13 ) is cured, radiating with electrons the adhesive layer ( 13 ) of an electron-beam-curable adhesive and the laminate ( 10 ) to cure the adhesive, the adhesive layer ( 13 ) of the electron-beam-curable adhesive is cured at a high voltage of 70 to 100 kV by means of an electron-beam directed at the surface of the laminate ( 10 ) delivering a radiation dose amounting to 10 to 50 kGy, the laminate ( 10 ) has the following structure: oPP-film ( 12 )/printing ( 11 )/adhesive ( 13 ) of an electron-beam-curable adhesive/oPP-film ( 16 ).
