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.
The 6-mil (152.4-micron) PCTFE film can be laminated to a variety of substrate materials including PVC, PP, COC, PETG, PE, and EVOH, resulting in several innovative structures that offer improvements in moisture barrier
of up to 71 percent.
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.
Because PLA is hydrophilic and wants to absorb moisture, Frito Lay needed to also develop a high moisture barrier
lamination film, applied between a metallic barrier layer and the PLA inner layer, to prevent damage to the food.
The system utilizes components that are both self-priming and feature a built-in moisture barrier
, which can save several days in installation time.
