PE Shink Film
PE heat shrink film is commonly used in various industries, including food and beverage, pharmaceuticals, electronics, and retail. It provides protection and tamper-evident packaging for products, ensuring their integrity during transportation and storage.
The film is typically applied using heat shrink machines or heat guns, which apply heat to the film, causing it to shrink and conform to the shape of the product. The film has excellent clarity, allowing for easy visibility of the packaged item, and it can be printed on for branding and labeling purposes.

Swing Check Valve is designed to prevent backflow in pipelines. The flow passes straight through the valve, resulting in minimal pressure drop. The disc swings open as media flows through the line, and back pressure keeps it closed. These valves can be installed in horizontal or vertical lines but must be aligned with the flow direction indicated by the arrow on the body.
