Certificates
- tesa® 4965 Original Next Gen contains a total of 62% biocarbon content (including red MOPP liner), which is composed of 20% bio-based carbon content directly derived from biological sources and 42% bio-attributed carbon content from the use of biomass balanced adhesive components that are ISCC PLUS certified.
- The double-sided mounting tape contains a 90% recycled PET backing, resulting in an average of 5% post-consumer recycled content (including red MOPP liner) in the tape. This is a third-party environmental claim validated against the UL Environmental Claim Validation Procedure 2809 for recycled content. The UL Environmental Claim Validation Program falls under UL’s ISO/IEC 17025 accreditation.
