Transparent Oxide Barrier Replaces Metallised Film Steadily
Aluminium foil delivers absolute barrier and cannot be sorted or recycled in a polyolefin stream. Metallised film is lighter and cheaper but reads as metal to sorting equipment and pinholes when flexed. Silicon and aluminium oxide coatings applied to polyester or polypropylene give usable oxygen and moisture barrier while remaining transparent and sortable as plastic. Coating cost is higher and barrier performance still trails foil, which restricts application to products with moderate rather than extreme shelf life requirements. Growth runs at 9.0% against a market rate of 6.0%. Brand owners can also show the product through it.
Market Impact: India grows at 10.2% annually
