Specification 3.2.3 · Paper 1
Revise: Packaging LaminatesA familiar example is a Tetra Pak™ carton containing paperboard, polyethylene and aluminium foil.
Link each material to its particular function: paperboard provides stiffness, polyethylene controls moisture movement and bonds layers, and aluminium foil blocks oxygen and light.
For an explanation, connect the property to the product: ‘Polyethylene provides a moisture barrier, so the paperboard does not become wet and lose stiffness.’
