日本JSP公司最近在世界上首次研制成功直链状低密度聚乙烯(LLDPE)的无交联中空颗粒发泡材料(简称L板材),并已正式投放市场。这种以直链状低密度聚乙烯为原料的L板材具有一些以往的聚乙烯发泡材料所没有的特点。它在反复使用后,仍不会出现材料疲劳的现象,因而最适合用作周转箱。而且可用带锯、切片刀和水果刀等切断或剖开,又无粉末飞散开来。该材料有较好的耐油、耐酸和耐碱性,适合包装那些沾附有油脂的 Japan’s JSP company recently successfully developed the world’s first straight-chain low density polyethylene (LLDPE) non-crosslinked hollow particle foaming material (referred to as L plate), and has been officially on the market. This linear low-density polyethylene as raw material L plate with some conventional polyethylene foam material does not have the characteristics. It does not appear material fatigue after repeated use, and therefore most suitable for use as a turnover box. But also with band saws, slicing knife and fruit knife cut off or cut open, and no powder to fly away. The material has good oil, acid and alkali resistance, suitable for packaging those with grease
