Moistop Barrier Foils
Barrier foils are a 3 or 4 ply laminate consisting of Polyester, Aluminium Foil, and Polyethylene which are used to prevent corrosion and moisture damage. The key to the product is the Aluminium foil layer which acts as a gas barrier making the laminate a form of flexible ‘tin can’. Often used for lining showcases as a barrier against gas emissions from wood or MDF board. The benefits of using Barrier Foil are as follows. Benefits - Up to 80 times more effective at preventing water vapour ingress than polythene
- Substantial reduction in desiccant usage offers overall savings.
- Resistant to physical damage, U.V., acid, alkalis, chemical and biological degradation.
- Saves costs on outer pack quality, case linings and preservatives.
- Much quicker to heat seal with better seal integrity.
- Approved to U.K., DEF, STAN 81/41 & USA MILB131H
