定义
拉伸膜黄大仙精选资料三天肖三码又叫缠绕膜,国内最早以PVC为基材,DOA为增塑剂兼起自粘作 用生产PVC缠绕膜。由于环保问题、成本高(相对PE比重大,单位包装面积少)、拉伸性差等原因,当1994~1995年国内开始生产PE拉伸膜时逐步被 淘汰。PE拉伸膜先是以EVA为自粘材料,但其成本高,又有味道,后发展用PIB、VLDPE为自粘材料,基材现在以LLDPE为方,包括C4、C6、 C8及茂金属PE(MPE)。

生产工艺条件
黄大仙精选资料三天肖三码 流延法生产由于流道长 而窄,流动速度快,熔体温度范围一般控制在<?xml:namespace prefix = st1 />250℃~280℃,流延冷却辊的温度控制在20℃~30℃,收卷张力要低,一般在10kg以内,以利粘性剂迁 出,同时减少成品膜内应力。

应用
拉伸膜的应用领域很广,主要是与托盘配合使用,对零散商品进行整集包装,代替小型集装箱。由于它可降低批量货物运输包装成本30%以上,因而被广泛应用于五金、矿产、化工、医药、食品、机械等多种产品的整集包装上;在仓库贮存领域,国外也较多地利用拉伸缠绕膜托盘包装进行立体贮运,以节省空间和占地。主要使用形式如下:

拉伸膜的包装都须经过拉伸,托盘机械包装的拉伸形式有直接拉伸和预拉伸。综上所述,拉伸膜的应用领域非常之 广,而国内很多的领域还未涉及,已涉及的许多领域也未普遍使用,随着应用领域的扩大,拉伸膜的用量必将大大增长,其市场潜力是不可估量的。所以我们有必要大力推广拉伸膜的生产和应用
