EVOH copolymer is defined by the mole % ethylene content: lower ethylene content grades have higher barrier properties; higher ethylene content grades have lower temperatures for extrusion. The plastic resin is commonly used as an oxygen barrier in food packaging. It is better than other plastics at keeping air out and flavors in, is highly ...
LED wallpaper. LED wallpaper is the integration of light-emitting diodes into flat substrates suitable to be applied to walls for interior decoration purposes..
