BOPP AlOx Film can enter evaluation for transparent microwave pouches where a PP-oriented barrier structure is being considered. Microwave suitability must be proven with the food, seals and venting method, not inferred from the film name.
An AlOx Film Supplier needs the package structure, fill weight, heating instructions, peak product temperature and required OTR/WVTR. Cailong lists BOPP AlOx for transparent high-barrier packaging and states microwave use among its applications.
Record microwave power, heating time, starting temperature and whether the pouch is opened, vented or heated closed. Include uneven food heating in the risk review.
Inspect folds, gussets, seals and the coated interface before and after heating. Evaluate distortion, delamination, leakage and barrier change.
Run repeated trials with the actual product and consumer instructions. Send Cailong the grade, structure, heating cycle and failed samples.
