Frequently Asked Questions

Yes. The 2-inch width and standard paper core are compatible with most industrial tape dispensers used on packing lines. The 4.6 mil thickness feeds smoothly without binding or slippage issues.

The acrylic adhesive maintains excellent adhesion in freezer and refrigerated conditions (down to -20°F). Thermal conductivity prevents adhesive failure during temperature cycling, ensuring case seals remain intact throughout the cold chain.

This tape meets UL 723 and UL 764c safety standards. For direct food contact applications, verify compliance with your specific regulatory requirements. It is best suited for structural sealing of shipping cases rather than direct product contact.

The aluminum backing provides a moisture and air barrier that improves case integrity, especially for refrigerated or outdoor shipments. It also offers light reflectivity for visibility and UV resistance that extends tape durability, reducing seal failures on your packing line.
