  生产技术与特点: 环保收缩膜的生产通常采用挤出吹塑或挤出流延法生产出厚膜,然后在软化温度以上、熔融温度以下的一个高弹态温度下进行纵向和横向拉伸,或者只在其中的一个方向上拉伸定向,而另一个方向上不拉伸,前者叫双轴拉伸收缩膜,而后者叫单向收缩膜。使用时,在大于拉伸温度或接近于拉伸温度时就可靠收缩力把被包装商品包扎住。收缩包装具有以下优点:

  (7) 透明性好,顾客可以直接看到商品内容。市场发展与典型应用热缩膜所用材料主要为各种热塑性薄膜。最初以PVC收缩膜为主,随着市场需求不断发展,PVC收缩膜逐渐减少,而各种PE、PP、POF等多层共挤热缩膜发展迅速,成为市场主流。,市场正在进一步扩大。据专家预测,国内热缩薄膜市场将以20%以上的速度增长。食品工业是热缩包装最大的市场。热缩薄膜广泛应用于各种快餐食品、乳酸类食品、饮料、PVC收缩膜、小食品、啤酒罐、各种酒类、农副产品、干食品、土特产等的包装。在非食品领域应用也日渐增多,如标签及瓶盖、封口、纤维及衣物、气溶胶制品、体育用品、电气制品、化妆品、医药品、油脂、洗涤剂、文具、玩具、办公用品、厨房用品、日用品、杂品、建筑材料等。

  热收缩膜标签有两种使用方法:整体套标收缩法(full-body shrink sleeves)和滚标(roll-fed)法。这两种方法有一个共同特征是都将平均50微米厚度的塑料膜围先绕在一个瓶体上然后进行加热,产生的热量使膜沿着瓶体轮廓收缩。其中套标收缩法是比较常用的工艺,而滚标法正在快速发展之中。整体套标收缩膜的挤出过程通常都含有一个横向的取向工序。薄膜在印刷好后做成筒状标签,然后加工机器将筒状标签分切成具有一定长度的套标,接着将瓶子放在套标内部,接下来让瓶子和套标一起通过一个以蒸汽或红外光为加热媒质的烘道,热量促使套标收缩并生成紧贴在瓶体上的标签。薄膜的典型收缩率范围为50%-80%。具有不规则几何外形的瓶体适合使用这种具有高收缩率的套标系统。套标PVC收缩膜最常用的树脂材料有PVC、乙二醇改性聚酯(PETG)和取向聚苯乙烯(OPS)。滚标工艺首先要有一个预先印好的薄膜,通过拾取工序和热熔胶的粘结支撑作用将膜材料环绕在瓶体上并形成闭合结构,然后将被包袱的瓶体送进一个热烘道,烘道里的热量使薄膜收缩紧紧贴到瓶体表面。双轴取向聚丙烯 (OPP)是最常用的滚标系统用树脂材料。由于OPP热缩膜在机器上产生了取向作用,因此滚标法收缩膜最终的收缩率比套标法的小,在5%-20%的范围内。常用的瓶体材料有PET、PP、HDPE或者玻璃等。滚标法一般适用于收缩率不高、结构不太复杂的瓶体结构。文章来源:http://jadigg.com/
