摘　　要：概述了从源头减少消费后塑料包装材料的各种减量化技术,包括薄膜与容器等的减薄、包装结构的简化、反复使用与循环利用、使用回收料等;阐释了为便于回收利用使用尽可能减少材料种类的理念——单一材质化与相应措施等。This paper introduced the technologies and solutions for raw material use‐reduction in the production of plastics packaging materials,which included the thinning of plastics films and containers,the structure simplification of packaging articles,the reusing and recycling of plastics packaging products and the use of recycled plastics materials as much as pos‐sible.The ideas and ways of large‐scale using one‐component materials in the manufacturing of plastics packaging materi‐als were described.

关 键 词：塑料包装材料 减量化 单材质化 反复使用 循环利用 回收料
