自动缠绕膜机器，也称为上下断膜缠绕包装机，是一种现代化的自动化包装设备。这种机器主要用于对托盘上堆放的产品进行均匀、紧实且稳定的拉伸膜缠绕包装，以达到防尘、防潮、加固和减少运输过程中货物散落或破损的目的。

上下断膜缠绕包装机的特点在于其能够在托盘货物顶部和底部自动切断缠绕膜，确保包装过程连续且无须人工干预，提高了生产效率和包装质量。这类机器通常配备有预拉伸系统，可以根据需要调整薄膜张力和层数，并通过PLC控制实现多种包装模式，适应不同规格和形状的货物。

在实际应用中，上下断膜缠绕包装机适用于物流、仓储、制造等多个行业的大批量货物出库前的打包作业。

The automatic stretch film machine, also known as the upper and lower broken film wrapping machine, is a modern automatic packaging equipment. This kind of machine is mainly used for even, tight and stable stretch film wrapping and packaging of products stacked on pallets, so as to achieve the purpose of dustproof, moisture-proof, reinforcement and reducing the scattering or damage of goods during transportation.

The upper and lower stretch wrapping machine is characterized by its ability to automatically cut the stretch film at the top and bottom of the pallet goods, ensuring that the packaging process is continuous and without manual intervention, improving production efficiency and packaging quality. This type of machine is usually equipped with a pre-stretching system, which can adjust the film tension and number of layers as needed, and realize a variety of packaging modes through PLC control to adapt to different specifications and shapes of goods.

In practical application, the upper and lower broken film stretching packaging machine is suitable for the packaging operation of large quantities of goods before leaving the warehouse in logistics, warehousing, manufacturing and other industries.
