근거 범위

Kraft-style laminate description, food-contact inner layers, window conversion, sealing checks and post-approval change control.

적용 범위와 한계

No paper, laminate or window route is universally suitable. Barrier, odour, migration, seal and shelf-life results require the exact materials and intended use.

핵심 요약

A kraft appearance does not identify the full laminate.
Food-contact status depends on each component and its conditions of use.
Converted-pouch sealing and window performance require sample validation.
