PET AlOx Film can be evaluated for transparent jerky packs when buyers want product visibility without giving up oxygen and moisture control. The laminate must also protect color, flavor and texture through storage.
An AlOx Film Supplier needs the jerky formulation, water activity, target shelf life, required OTR and WVTR, and storage climate. Cailong lists transparent PET AlOx grades for food packaging, but the grade must match the thermal and converting process.
Record whether the main risk is oxidation, moisture gain, moisture loss or aroma change. Include oxygen absorbers or other pack components in the trial plan instead of evaluating the film alone.
Confirm the print layer, AlOx orientation, adhesive and sealant. Check seals for contamination from oil, seasoning or product particles.
Monitor appearance, seal integrity and product condition under the intended storage profile. Send Cailong the structure, barrier target, filling method and failed packs.
