COPOLYAMIDE 6/66 FOR DEEP THERMOFORMING
Deep thermoforming is a process used to create high-depth packaging for bulky products like whole cuts of meat or cured items. These applications require materials that combine excellent flexibility, strength, and formability with optical clarity and durability.
Promyde BF840 L is specifically engineered for these needs, offering superior tear strength, puncture resistance, and high transparency. It enables secure, visually appealing packaging that maintains product integrity in the most demanding thermoforming conditions.
PROMYDE® BF840L
Promyde BF840 L is a lubricated, high-viscosity copolyamide 6/66, specifically designed for deep thermoforming applications. This advanced copolyamide offers enhanced processability, greater flexibility, and exceptional transparency, along with superior mechanical properties.
Its unique formulation ensures excellent tear strength and outstanding puncture resistance, making it an ideal choice for the production of high-performance films used in demanding packaging applications.
