It can protect products, prevent products from being physically damaged, ensure product quality, fix and display products, and help attract consumers; moreover, it is convenient for transportation and storage, effectively improving logistics efficiency.
[0004] At present, there are many types of packaging stretch films, such as polyethylene film, BOPP film, CPP film, PET film, etc. These packaging stretch films generally have a single-layer structure. The single-layer film is relatively thin. When using these packaging stretch films to package electronic products, the electronic products will be affected by external forces during transportation, generating vibrations or squeezing each other. Due to the unreasonable structural design of the packaging stretch film, the anti-stretching performance is not good, and the buffering performance is poor, resulting in the packaging stretch film being easily damaged and unable to protect the electronic products well, causing damage to the electronic products; in addition, the current packaging stretch film has poor shielding performance, and the electronic products are easily interfered by external electromagnetic waves, resulting in the quality of the electronic products not being guaranteed. Moreover, static electricity is easily generated on the outer surface of the packaging stretch film, which adsorbs dust, bringing a negative impact on the quality of the electronic products and causing inconvenience to production. The quality of the packaging stretch film is average and cannot meet the existing needs. Therefore, it is necessary to study a new technical solution to improve the current packaging stretch film.
