BOPP AlOx Film can enter evaluation for PP-oriented detergent refill pouches that need printing and barrier performance. Chemical compatibility cannot be assumed because surfactants, fragrance oils and storage temperature may affect the laminate.
An AlOx Film Supplier needs the formulation, pouch structure, fill temperature, storage conditions and required barrier. Cailong positions BOPP AlOx for transparent PP-based high-barrier structures, while the final pack requires customer validation.
Define the Contact Risk
List the detergent form, fragrance content, pH range and expected contact time. Include product on the seal area and exterior splash exposure in the test plan.
Check the PP Structure
Confirm print, adhesive and sealant compatibility. Inspect swelling, whitening, delamination and seal creep after upright and inverted storage.
Qualify the Filled Pouch
Run leakage, drop and storage tests using the real formulation. Send Cailong the structure, conditions, observations and failed samples.
