Express bags are one of the commonly used packaging materials in the express industry. They are used to package and protect goods so that they are not damaged during transportation.
There are many types of express bags, among which plastic express bags are the most widely used. Because they are lightweight, waterproof, and easy to process, they are often used to wrap lightweight items.
Express bags are made of plastic materials such as polyethylene and polypropylene. These materials are lightweight, waterproof, and easy to process. At the same time, some express bags also add materials such as air cushion film to increase their pressure resistance, earthquake resistance and other properties.
The characteristics of express bags are mainly reflected in the following aspects:
• Lightweight: Express bags are usually made of lightweight materials to reduce shipping weight and reduce shipping costs.
• Waterproof: The material of the express bag is usually waterproof, which can effectively protect the packaged items from moisture.
• Compression resistance: The material of the express bag has certain compression resistance, which can protect the packaged items from external forces such as extrusion during transportation.
• Transparency: The material of the express bag is usually highly transparent, making it easier for the recipient to view the package contents.
• Environmental protection: Some express bags are made of recyclable materials, which meet environmental protection requirements and help reduce environmental pollution.
