FAQs
When do I need a liner?
Use liners when products are oily, moist, aromatic, or light-sensitive—or when regulations demand migration control.
PE vs MetPET—how to choose?
PE/greaseproof protects from oil/moisture at best cost. MetPET/foil adds light/aroma barrier and a premium metallic base. We’ll recommend based on your product.
Can I add windows or inserts?
Yes—window patching and board/micro-flute inserts are available; liner maps are adjusted accordingly.
What details do you need to quote?
Style, dimensions, board GSM, liner type/coverage, finishes, artwork status, and quantities per SKU.
