连卷的方便袋是我们日常生活中很常见的一种塑料袋，例如在里买的东西的时候看到的都是用这种连卷的方便袋包装好以后销售的食品。连卷的方便袋一般使用HDPE材质为原料，是一种结晶度高、非性的热塑性树脂。高密度聚乙烯为无味、无臭的白色颗粒，熔点约为130℃，它具有良好的耐热性和耐寒性，化学稳定性好，还具有较高的刚性和韧性，机械强度好。

The continuous roll convenience bag is a very common plastic bag in our daily life. For example, when we buy things in the supermarket, we see the food packaged with this continuous roll convenience bag. Continuous roll convenience bags generally use HDPE as raw material, which is a thermoplastic resin with high crystallinity and non plasticity. HDPE is tasteless and odorless white particles with a melting point of about 130 ℃. It has good heat and cold resistance, good chemical stability, high rigidity and toughness and good mechanical strength.
