Oxygen Barrier
Oxygen-barrier needs vary by product, target shelf life, filling method, seal quality, storage and distribution. Compare candidate structures using project-specific data and finished-pack validation.
Moisture Barrier
Moisture-barrier requirements depend on the packed product, ambient exposure, seal design and distribution conditions. Review material data together with seal and finished-pouch performance.
Light Protection
Foil, metallized film or an opaque printed structure may be considered when light exposure matters. Compare light protection with sealing, equipment, recycling and market needs, then validate the actual filled pack.
