In the production process of cross-linked film, radiation cross-linking technology is used to transform the polymer chain of the resin from a linear structure to a network structure, which significantly improves the performance of the shrink film, mainly reflected in the following aspects.
Increased Puncture Resistance - One of the primary benefits of a cross linked shrink film over normal POF shrink film. The cross linking of polymers increases puncture resistance enabling users to use thinner film while still obtaining the same strength. A thinner film offers a variety of benefits with the primary benefit being cost. Thinner shrink film also offers better clarity, faster sealing, and faster shrinking.
Stronger Seal Strength - The weakest point in a shrink wrapped package is the seal seams. A standard shrink film does not obtain the same seal strength as a cross linked shrink film. Stronger seals reduce damaged packages and ensures customers are purchasing a product that has not been tampered with.
Less Residue - Over time a shrink film will leave residue behind on the sealing wire or blade. The left-behind residue causes the need to replace sealing wires and blades. For fully automatic machines making thousands of seals daily, a reduced residue is ideal for saving time and reducing the amount of replacement sealing blades.
Increased Clarity - The ability to use a thinner film with comparable strength increases the clarity of the shrink film. Irradiated cross linked shrink film also has less haze for better clarity.
Longer Rolls - For Cross-linked film,the thinnest thickness we can make is 12mic,the standard length is 1667meter. Longer rolls mean less downtime for roll changes and more time for production.
