Abstract:Ethylene vinyl acetate hot melt adhesive was used as anti-skid coating to combine with PE packaging film, EVA sprayed PE anti-skid packaging material (E-S-PE) and heat treatment EVA sprayed PE anti-skid packaging material (HE-S-PE) were prepared after thermal spraying and heat treatment. The effects of spray quantity and heat treatment process on the anti-skid performance, bond strength and mechanical properties of the composites material were studied by means of scanning electron microscope, friction coefficient/peel tester, and intelligent electronic tensile testing machine, and the optimum quantity of spray coating was obtained. The results showed that the friction coefficient of E-S-PE and HE-S-PE increased then stabilized with the increase in spray quantity , and the friction coefficient reach the maximum when spray quantity was 40 g/m2 and 70 g/m2 respectively. However, the mechanical properties of the composite films decreased with the increase in spray quantity, and the mechanical properties of HE-S-PE further decreased more than those of E-S-PE. Therefore, the optimal spraying quantity of the anti-skid material was 40 g/m2.
