簡(jiǎn)介 Introduction

簡(jiǎn)單的講就是卷起來(lái)的包裝膜，對(duì)包裝生產(chǎn)企業(yè)而言只是比生產(chǎn)成品袋少了一道工序而已，其材質(zhì)種類也與塑料包裝袋一致，常見的有PVC收縮膜卷膜，opp卷膜，pe卷膜，pet保護(hù)膜，復(fù)合卷膜等。卷膜應(yīng)用于自動(dòng)包裝機(jī)，如常見的袋裝洗發(fā)水，部分濕巾等就采用這種包裝模式。采用卷膜包裝成本相對(duì)較低但需要配套自動(dòng)包裝機(jī)。

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.

優(yōu)勢(shì) 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.
