| 普通吹膜生产工艺属于单泡法，由于无法精确控制薄膜在纵向和横向上的吹胀和拉伸比例，且吹胀比一般在2~3左右，薄膜的热收缩率不高，因此一泡法生产的产品主要用于产品物流中的包装，如啤酒饮料、日用电子产品的外包装等。 The ordinary blown film production process belongs to the single-bubble process. Because the blown and stretched ratio of the film in the vertical and horizontal direction can not be accurately controlled, and the blown ratio is generally about 2-3, the thermal shrinkage rate of the film is not high, so the products produced by one-bubble process are mainly used in the packaging of product logistics, such as beer beverage, daily electronic products, etc. |
