What are the packaging properties of TPU packaging films?

TPU packaging film has a variety of packaging properties, the following are the main aspects:
Good sealing: It can closely fit the packaged items, effectively prevent moisture, dust, impurities, etc. from entering, and provide reliable protection for products that need to be moisture-proof and dust-proof, such as electronic products and precision instruments. For example, in mobile phone packaging, TPU packaging film ensures that the mobile phone is not affected by the external environment during transportation and storage, and maintains good performance and appearance.
High toughness and puncture resistance: It has strong toughness, is not easy to break, and can withstand certain external force extrusion and impact. At the same time, it has a good resistance to the puncture of sharp objects, which can avoid the contents of the package being punctured by sharp objects when handling or being accidentally squeezed. This is important for packaging fragile or angular items, effectively reducing the risk of packaging damage and reducing the loss of goods.
Suitable stretchability: It can be stretched according to the shape and size of the packaged item, perfectly fitting all corners of the item, and providing a full range of wrapping effects. Whether it is an irregularly shaped item or a large object, TPU packaging film can be used for effective packaging, reducing packaging voids, saving packaging space and improving packaging efficiency.
Excellent chemical resistance: It has good resistance to most chemical substances and will not deteriorate or be damaged by contact with common chemical reagents, solvents, etc. This gives TPU packaging films a unique advantage when packaging chemical products, pharmaceutical products, etc., to ensure the safety and stability of the contents of the package.
Optical transparency (some products): Some TPU packaging films have high optical transparency and do not affect the appearance of the packaged items, which is suitable for products that require packaging transparency, such as cosmetics, food, etc. Consumers can directly see the contents of the package, adding to the attractiveness of the product.
Heat sealability: Convenient for heat sealing, which can quickly and securely seal the packaging film to ensure the integrity of the package. The heat sealing process is simple and fast, which improves the production efficiency of the package, and also ensures the tightness and stability of the package.
Eco-friendliness: With the improvement of environmental awareness, the environmental performance of TPU packaging film has also attracted much attention. Many TPU packaging films are available and can be processed through corresponding treatment processes after use, reducing pollution to the environment and meeting the requirements of modern society for sustainable development.
In short, TPU packaging film has been widely used in the packaging field of various industries due to its good sealing, high toughness, suitable stretchability, chemical resistance, optical transparency (partial), heat sealability and environmental protection and other packaging properties, providing a strong guarantee for the safe transportation and storage of products.
