PET AlOx Film can be evaluated for dried-fruit packaging when brands want product visibility with oxygen and moisture control. Color change may also involve light, formulation and seal leakage, so the barrier film should be tested within the complete pack.
An AlOx Film Supplier needs the fruit type, target shelf life, required OTR and WVTR, light exposure and storage climate. Cailong lists transparent PET AlOx grades for dried food and other high-barrier applications.
Compare oxidation, moisture gain and light exposure under controlled conditions. Record preservatives, headspace and any oxygen absorber so their effects are not assigned to the film.
Confirm the print layer, AlOx orientation, adhesive and sealant. Inspect seal contamination from sugar or fruit particles and test pouch corners separately.
Track color, aroma, texture and package integrity through storage. Send Cailong the structure, conditions, barrier targets and failed packs.
