It is typically supplied in a center-folded format, where a large roll of film is folded in half, resulting in a more manageable and convenient 400mm roll width. This center-fold design allows for easy handling and wrapping of products.
To use the shrink film, the product is placed between the two layers of film, and the open sides are sealed. This can be done using heat sealing equipment or other suitable sealing methods. Once the product is securely wrapped, it is ready to be subjected to heat for the shrinking process.
The wrapped product is then placed in a shrink tunnel or chamber, where controlled heat is applied. As the heat is distributed evenly, the shrink film begins to shrink and conform tightly around the product, creating a snug and protective packaging layer. The shrinking process not only provides a secure hold but also enhances the visual appeal of the packaged item.
Shrink film is widely used for packaging a variety of products, including food items, beverages, cosmetics, electronics, and more. It offers several advantages such as tamper-evident sealing, moisture protection, and improved product presentation. Additionally, the shrink film is compatible with automated packaging machinery, allowing for efficient and streamlined packaging operations.
Overall, the shrink film provides a reliable and cost-effective packaging solution that ensures product integrity, enhances shelf appeal, and meets the diverse packaging needs of different industries.
