TAFMER™ XM is a high-quality low-crystallinity propylene and α-olefin copolymer, suitable for biaxially oriented polypropylene (PP) and cast film sealants, as well as a modifier for polyolefin resins. TAFMER XM is developed using metallocene catalysts. This material exhibits excellent low-temperature sealing properties, good sealing performance over a wide temperature range, and good anti-blocking properties. As a heat-seal layer for OPP films, TAFMER XM is an excellent packaging sealer, suitable for products such as chocolate, biscuits, and crackers. Additionally, TAFMER XM can improve the low-temperature shrinkage characteristics of PP.
