Common questions
Will this tape work with our automatic case sealing equipment?
Yes. The 3M 425 is engineered for dispenser use with standard 3-inch cores found on most case sealers. The acrylic adhesive activates cleanly without residue buildup, reducing downtime and maintenance on your packing line.
What makes the 4.6 mil thickness important for case sealing?
The 4.6 mil aluminum backing provides adequate rigidity to prevent tearing during high-speed application while maintaining flex for irregular cardboard surfaces. This thickness balances durability with cost-per-case efficiency on volume operations.
How does this tape seal water and air leaks?
The aluminum foil layer acts as a moisture barrier blocking water vapor ingress, while the acrylic adhesive creates an airtight seal on case edges and seams. This dual protection is critical for refrigerated shipments or products sensitive to humidity.
Is this tape suitable for outdoor storage or transit?
Yes. The UV-resistant formulation prevents adhesive degradation and foil oxidation during weather exposure or extended outdoor holding. UL 723 flame resistance also meets safety requirements for certain hazmat and temperature-controlled applications.
