The major advantage of a nine-layer blown film line is
capable to split film layers into thin ones. It improves
barrier performance, as well as the ability for the film to be
thermoformed and more uniform gauge. Sealant layers can be thinner,
which increases the likelihood of down gauging and cost reduction.
These thinner layers can also reduce film curling, a common problem
with five- and seven-layer nylon films.
