  • Sequential bio-oriented film, which can layer up to 5 types 7 layers.

01

Pinhole-resistant nylon for the frozen environment

Recently, cold chain(low temperature transportation network) has expanded for the purpose of extending the shelf life of food. However, because of the low temperature, the burden on the packaging is getting bigger.

Food loss reduction

Advantage (layer composition)

Added cold-resistant function to the conventional pinhole-resistant grade, which are barrier (type PF) and non-barrier (type PG). Selectable depending on the application.

  1. Strengthen pinhole-resistant: Effective in preventing all pinholes.
  2. Add cold-resistant: Maintains flexibility in freezing and refrigerating environments.
  3. Multi-layered: Add multiple functions by multi-layer technology.
