Oxide Coating Delivers Foil Barrier Without the Foil
Aluminium oxide and silicon oxide deposited a few nanometres thick onto polyester or polypropylene deliver oxygen and moisture barrier approaching foil, while staying transparent and microwaveable, neither of which foil manages. That combination is what pulls volume across: brands get the pack window consumers want and the shelf life the category demands from one structure. Growth runs at 9.6% against 6.4% for the market overall. Deposition capacity and flex-crack resistance are the two constraints holding it back. Foil still holds the applications where a pinhole cannot be tolerated at any price, and that boundary has moved slowly.
