热熔型纸塑复合预涂膜的研制

Hot melt type precoated adhesive film used in composite of paper and plastic

以EVA弹性体为主体材料,配以适宜的增粘树脂及其他助剂,制成热熔胶粘剂并涂于BOPP或聚酯膜上,用于纸塑复合。讨论了各种基料对热熔胶软化点、熔融粘度的影响。该预涂膜性能优良,无毒无污染,复合工艺简单,可提高生产效率。

The hot melt adhesive of EVA elastomer mixed with suitable tackifying resin and other auxiliary agent was studied in this paper. The effect of various materials on soften point and melt viscosity of hot melt adhesive were discussed. The hot melt adhesive was spreaded on BOPP or polyester film used in composite of paper and plastic. The precoated adhesive film has good performance, simple technics of compound, nonpoisonous, pollutionfree and high production efficiency.
