Historically, polyethylene and wax coatings have been used to seal porous paper, corrugated boxes, and sheets to provide a
moisture barrier and/or moisture-vapor barrier to these substrates.
His findings are contained in a paper, "Sealable Seal Films with Enhanced
Moisture Barrier Properties for Flexible Packaging Applications," presented at the SPE ANTEC in Orlando in March.
To keep your protective keep your protective T
moisture barrier intact, top up throughout the day or switch your foundation for BB or CC creams with SPF50.
Typical applications include coating of medical micro circuits, also sealing and
moisture barriers encompassing substrates such as glass, FR-4, metal, ceramic, glass filled epoxy, CAP, PS, TPU and aluminium.
Other potential problems include a substandard
moisture barrier or insufficient support from the subflooring.
NatureFlex NVR is a two-side coated, heat sealable renewable and certified compostable film with an intermediate
moisture barrier, ideally suited to box overwrap and individual flow wrap applications.
It's a bit pricey but this improved version of their original Surge product not only hydrates skin (used over eight weeks moisture is increased by over 40%) but it also contains
moisture barrier technology to retain and bind moisture to the skin.
Innovia Films manufactures cellulose-based renewable and compostable filmic solutions that offer the necessary oxygen and
moisture barrier properties required for dried foods.
Two polyethylene grades for barrier film extrusion from Nova Chemicals are said to bring up to 50 per cent higher
moisture barrier performance than existing materials.
