Best Energy Product
CPP and Pouch Film
Hygienic, heat-sealable material with
excellent transparency and gloss
CPP Film Description
CPP film refers to a non-stretched film that has not undergone a stretching operation, which is an operation that uniformly applies heat to the molecular chain direction of a polypropylene material in one direction. The CPP film manufactured in this way is hygienic, has heat sealing properties, and has excellent transparency and gloss, making it an important material that accounts for 40% of the price not only for food packaging but also for pouch films, which are exterior materials for secondary batteries.
In the meantime, there was no CPP film suitable for medium and large-sized pouch-type secondary batteries in Korea, so all products made in Japan were used.
A bridgehead for secondary battery technology independence, pouch film
Pouch film is an exterior material used for pouch-type secondary batteries. The reason that pouch-type secondary batteries can be used for a long time due to their high space efficiency and high energy density is because the pouch film, which is a packaging material, can be freely molded, making it easy to design secondary batteries. Best Energy has localized CPP film, which is essential for pouch film, and based on this, is the only domestic attempt to localize all materials for pouch film.
Through this, Best Energy is developing with the goal of diversifying the domestic market, which has had no choice but to rely heavily on materials made in Japan, and providing a stable supply chain for domestic secondary battery manufacturers.
Graphene pouch film
newly made with
new material graphene
The challenge of Best Energy does not stop here.
Best Energy is challenging to develop a graphene pouch film using a new material, graphene, beyond the simple localization of pouch film.
Graphene is a hexagonal carbon structure that is 200 times stronger than steel. Graphene, which has good ductility, heat dissipation and electrolyte resistance, and strong resistance to external shocks, is expected to solve the problem of internal heat dissipation of secondary batteries and extend battery life thanks to its excellent thermal conductivity.
Best Energy will try to give a fresh shock to the existing pouch film market by diversifying its products by combining a film made of graphene material with our CPP film.
