随着物流业的兴起， 拉伸膜 也得到了广泛的应用。拉伸膜主要用于包装和捆绑一些零散的物品。具有防水、防潮、防腐等功能。反观拉伸膜断裂现象，很多客户会认为拉伸膜的质量是在生产过程中改变了生产原料造成的。缠绕膜在包装过程中处理不当，一拉就断了怎么办？
如何防止手拉膜破裂的细节如下：
包装时要注意保护拉伸膜的边缘不被磕碰，避免出现边缘开裂和质量问题的现象。此外，要切割的周边整齐，切割时均匀。制作时，要把两面卷起来整齐。制作时，将模头清洗干净，以免有黑色污染，不要将烧焦的塑料掉入拉伸膜中。
With the help of the retraction force of the stretch film, the product is wrapped and packaged to form a compact unit that does not take up space so that the trays of the product are tightly wrapped together, which can effectively prevent the products from being misaligned during transportation. With the movement, the elastic stretching force can make the complex products close to each other and the soft products tighten, especially in the tobacco and textile industries, which have a packaging effect.
Stretch film has high tensile strength, significant elongation, good flexibility, and high transparency and can be widely used in the centralized packaging of various goods. It will not be scattered, damaged, or polluted during storage and transportation. At the same time, due to its high transparency, it is easy to identify and reduce distribution errors. It is also convenient for containerized storage and transportation, especially for pallet packaging. It can realize mechanized loading and unloading operations and significantly improve the packaging and transportation speed. This product is mainly suitable for pallet packaging goods, such as electronics, building materials, chemicals, metal products, auto parts, and wires—bundled packaging for cables, daily necessities, food, and other industries.
一般来说，透气率和透气系数是衡量渗透率的主要指标。恒温下的透气性决定了拉伸膜的透气性。也可以利用测试设置高压室和低压室，分别测试和销售，用压力表检测低压室的压力上升和变化。其中，要注意高低压的压差，确保在高低压两个腔的压差下进行检验过程。因此，为保证测试数据的准确性，拉伸膜保持恒定的透气性。注意工作仪器中各系统的密封性。
