AFFINITY™ PL 1845G is a cast-film polyolefin plastomer (POP) from Dow, produced via INSITE™ Technology. Designed specifically as a low-temperature heat-seal layer for BOPP composite films, it offers ultra-low seal initiation temperature, outstanding optics, and coextrusion compatibility. With no antiblock agents, it meets high-purity requirements for food packaging and complies with global food contact standards.
Ultra-low heat-seal initiation temperature:Reliable sealing at 95.0°C, 5–10°C lower than traditional materials, boosting packaging efficiency and reducing seal shrinkage
Excellent optical performance:Ultra-low haze (0.700%) and high gloss (145%), enhancing content visibility and packaging aesthetics
Superior mechanical properties:High tensile strength, elongation, dart impact, and tear resistance to prevent damage during transport
Antiblock-free formulation:No antiblock agents; slip/antiblock masterbatches based on polyolefin plastomers are recommended for optimal performance, meeting high-purity requirements
Excellent coextrusion compatibility:Works seamlessly with BOPP and other polypropylene polymers to improve interlayer adhesion and structural stability
Regulatory compliance:Compliant with Canadian HPFB, EU No 10/2011, and U.S. FDA FCN 424 food contact standards
Heat-seal layer for BOPP composite films:For flexible packaging of food, tobacco, and personal care products, delivering low-temperature sealing and high clarity
High-clarity food packaging:Cast films for baked goods and snacks, balancing optical performance and impact resistance
Tobacco packaging:Heat-seal layer for cigarette cartons/packs, ensuring reliable sealing and premium appearance
Personal care packaging:Composite tubes for shampoos/skincare and mask pouches, enhancing packaging quality and seal integrity
High-purity packaging:For medical and electronic component packaging, meeting additive-free, low-residue requirements
