Description

Technical Field

[0001] The utility model relates to the field of winding films, in particular to a waterproof and corrosion-resistant winding film. Background Art

[0002] Stretch film is used for wrapping to make the package more stable and neat. It is used in foreign trade export, papermaking, hardware, plastic chemicals, building materials, food and medicine industries.

[0003] Freighters travel at sea for a long time, which also causes the goods to be in a humid environment for a long time. The existing stretch film does not have good waterproof performance. External moisture can easily penetrate through the stretch film and penetrate into the product, causing water to seep into the product. In addition, the existing stretch film has weak anti-corrosion ability. After the stretch film is wrapped around the product, it is easily damaged by external corrosion, making the packaging ineffective. Therefore, it is necessary to improve the existing stretch film.
