2-layer laminated sheets (PE/18-8) with Polyethylene (PE) and austenitic 18-8 stainless steels (18-8) were prepared by a new adhesion method, a double-step treatment consisting of applying low dose (≦0.43 MGy) homogeneous low energy electron beam irradiation (HLEBI) prior to hot-press under 5 MPa and 343 K. Although the weak hot-press adhesion of the PE/18-8 was observed without HLEBI, the new adhesion raised the bonding forces as evidenced by the mean adhesive forces of peeling resistance (oFp). Based on the 3-parameter Weibull equation, the lowest oFp value at peeling probability (Pp) of zero (Fs) could be estimated. An increasing trend in Fs occurred by the double-step treatment applying HLEBI up to 0.30 MGy reaching a maximum at 0.85 N m−1, improving the safety level without radiation damage. When HLEBI cut the chemical bonds in PE polymer and generated terminated atoms with dangling bonds, they probably induced the chemical bonding. Therefore, increasing adhesion force between the laminated sheets could be explained.
