High Barrier Film for Humid-Climate Exports

High Barrier Film selected for humid-climate exports must be evaluated beyond a dry laboratory. Long transit, warm storage, condensation and seal variation can expose weaknesses that do not appear in incoming-film data.

A Metallized Film Supplier needs the laminate, product sensitivity, target WVTR, route and storage profile. Cailong publishes grade-specific information for VPET-GZ, but finished-package performance must match the customer's conditions.

Build the Exposure Profile

Record transport duration, temperature, relative humidity, warehouse conditions and possible condensation. Include carton and pallet configuration where they affect pouch compression.

Inspect the Whole Package

Check seals, folds, abrasion zones and laminate bonds after exposure. Separate panel transmission from leakage or delamination.

Compare Product Condition

Measure moisture-related product change with package integrity through the trial. Send Cailong the structure, exposure cycle, results and failed packs.
