Gelbo-Flex test is one of the durability indication against fabricating process, transportation and handling. Please find test data comprising some comparison with aluminum foil and aluminum metallized film on Table 1. For your reference, test results of Gelbo-Flex depend on equipment and condition sensitively.
1.
TECHBARRIER has superior Gelbo-Flex durability compared with aluminum foil and aluminum metallized film.
2.
TECHBARRIER-S especially has superior durability due to its base film, OPVA. We recommend it when toughness is required.
3.
TECHBARRIER-V, H, P2, T and TZ have almost same durability each other.
