Cailong

PET AlOx Film can be evaluated for transparent tea packaging when the pack needs oxygen and moisture control without hiding the product. Aroma loss may still come from seals, headspace or storage exposure rather than the flat film alone.

An AlOx Film Supplier needs the tea type, target shelf life, required OTR and WVTR, pack size and storage climate. Cailong lists transparent PET AlOx grades for tea and other food-barrier applications.

Define the Tea's Main Risk

Record whether the priority is aroma retention, moisture pickup, oxidation or color protection. Include headspace gas and any desiccant in the trial plan.

Review the Packaging Structure

Confirm the print layer, AlOx orientation, adhesive and sealant. Check zipper ends, gussets and seals for leakage where loose tea or powder may contaminate the seal area.

Test the Filled Pouch

Monitor aroma, moisture-related change and package integrity during storage. Send Cailong the structure, targets, filling conditions and failed packs.
