Description
技术领域
本发明涉及包装材料，特别是涉及一种环保隔热型复合保温包装材料。
背景技术
包装材料是工、农及家用中不可缺少的材料，而塑料包装是包装业中四大材料之一：纸及纸板占30%，塑料占25%，金属占25%，玻璃占15%。以上两个25%充分说明了塑料包装业的重要性。塑料包装业虽然是第二位包装材料，其实用面还不如纸及纸板的包装。但是塑料包装业每年按5%的速度在发展，可以肯定的讲，即使在塑料包装业受到责难最多的国家。塑料仍将以比其它包装材料快得多的速度在不段地发展，因为塑料的不少特性是其它任何一种包装材料所不能替代的。
众所周知，塑料是“白色垃圾”的主要来源，是影响人们环境的污染物之一。但对塑料的应用却无法禁止，如何对包装行业的塑料进行环保性及功能性生产制造，是塑料包装材料的主要研究方向。
