What’s the difference between a UV barrier and UV stabilization when it comes to protecting your goods with UV inhibitor shrink film?
It’s important to note that low-density polyethylene (LDPE) in its standard form is not inherently UV-resistant. This property is obtained by adding specific additives during the extrusion or co-extrusion process.
UV stabilization involves incorporating UV-absorbing agents into LDPE granules. This ensures that the UV inhibitor shrink film will not degrade under ultraviolet radiation for several months. Typically, such stabilization provides resistance ranging from 12 to 18 months, which is more than sufficient for outdoor storage—even in demanding environments.
Find the right solution for your needs
UV inhibitor shrink film can be applied to both transparent and opaque materials. However, only the opaque version—achieved by adding opacifying pigments to the LDPE granules—also acts as a UV barrier. This barrier not only protects the shrink film itself but also shields the covered products by blocking ultraviolet rays.
To effectively prevent product discoloration, degradation, or changes in appearance, it is recommended to use opaque UV inhibitor shrink film, in either light or dark colors depending on the product type and exposure conditions.
The effectiveness of the UV barrier is directly linked to the quality of the film’s UV stabilization. In other words, for a UV inhibitor shrink film to protect your goods for 12 months, the film itself must be stabilized to perform over that period—or longer.
This type of UV inhibitor shrink film is ideal for long-term outdoor storage in industrial, agricultural, maritime, or construction applications. It ensures the mechanical performance of the film is maintained while offering both structural and visual protection for your products.
Finally, items wrapped in UV inhibitor shrink film are protected not only from sunlight but also from moisture, dust, and surface scratches.
