description

CPP film refers to a non-stretched film without stretching, which is the work of applying heat in the molecular chain direction of polypropylene material in one direction and making it even. CPP film thus produced is hygienic, heat-sealing, and has excellent transparency and gloss, making it an important material that has a 40% price weight not only for food packaging but also for pouch film, an exterior material for secondary batteries.
Until now, in Korea, there was no CPP film suitable for medium and large pouch type secondary batteries, so all of them were made in Japan, but Best Energy contributed to the localization of materials by localizing CPP films for medium and large pouch type secondary batteries in Korea.

Korea’s only lead tab film localization and manufacturing success

Japanese companies occupy more than 90% of the global lead tab film market.
Under these circumstances, Best Energy is the only company that specializes in manufacturing lead tab films in Korea. Best Energy has succeeded in developing lead tab films for secondary batteries through many years of polymer research.

In particular, we contributed to the localization of secondary battery materials by using all raw materials used to manufacture them only domestically.
The lead tab film manufactured in this way has been tested in the safety field by China's top three secondary battery manufacturers for 6 months and its performance has been recognized.

FEATURES

Graphene pouch film newly made of New material graphene

Best Energy's challenge does not stop here.
Best Energy is challenging the development of graphene pouch films using the new material graphene, beyond simply localizing pouch films.

Graphene is a hexagonal carbon structure that is about 200 times stronger than steel.
Graphene, which has good ductility, heat resistance, and electrolyte resistance, is expected to extend the battery life by solving the heat dissipation problem inside the secondary battery, especially thanks to its excellent thermal conductivity.

Best Energy will try to combine films made of graphene with our CPP films to give a fresh shock to the existing pouch film market with product diversification.
