简介 Introduction

简单的讲就是卷起来的包装膜，对包装生产企业而言只是比生产成品袋少了一道工序而已，其材质种类也与塑料包装袋一致，常见的有PVC收缩膜卷膜，opp卷膜，pe卷膜，pet保护膜，复合卷膜等。卷膜应用于自动包装机，如常见的袋装洗发水，部分湿巾等就采用这种包装模式。采用卷膜包装成本相对较低但需要配套自动包装机。

Introduction Simply put, it is the rolling up packaging film, for packaging manufacturers is only less than the production of finished bags, its material types are also consistent with plastic packaging bags, common PVC shrink film roll film, OPP roll film, PE roll film, PET protective film, composite roll film, etc. Roll film is used in automatic packaging machines, such as common bagged shampoo, some wet wipes, etc. use this packaging mode. The cost of using roll film packaging is relatively low, but it needs to be equipped with automatic packaging machine.

优势 Advantage：

The main advantage of rolling film application in the packaging industry is to save the cost of the entire packaging process. Roll film is used in automatic packaging machinery, without any edge banding work in packaging manufacturers, only one-time edge banding operations in production enterprises. As a result, packaging manufacturers only need to carry out printing operations, and transportation costs are reduced due to the supply of rolls. When the roll film appears, the entire process of plastic packaging is simplified into three major steps of printing-transportation-packaging, which greatly simplifies the packaging process and reduces the cost of the entire industry, and is the first choice for small packaging.
