Water Vaper Permeability Tester for Food Industries Plastic Film Composite
Applications Specifications

Basic Applications	Films	Including plastic films, plastic composite films, paper-plastic composite films, geomembranes coextruded films, aluminized films, aluminum foils, aluminum foil composite films and many others
	Sheeting	Including engineering plastics, rubber and building materials, e.g. PP, PVC and PVDC
	Paper and PaperBoard	Including paper and paper board, e.g. aluminum foil paper for cigarette packages and Tetra Pak materials
	Textiles and Nonwovens	Including textiles and non-woven materials, e.g. waterproof breathable fabric, non-woven fabric for diapers and hygienic products

 

Extended Applications	Inverted Cup Method	Mount film or sheeting in test dish, cover upper surface of specimen with distilled water, and make the lower side in certain humidity. Generate a constant humidity difference between two sides; water vapor permeates through specimen and measure weight changes in different time to obtain the water vapor transmission rate. NOTE: inverted cups are required
	Artificial Skin	Artificial skin has to meet standard requirements for water vapor transmission rate to ensure better breath performance. This instrument can be used to test  water vapor permeability of artificial skin
	Medical Products and Accessories	Including plasters, aseptic wound protecting films, face masks and scar sticks
	Solar Back-Sheets	Including solar back-sheets
	LCD Monitor Films	Including LCD monitor films
	Paint Films	Test water vapor permeability of various sorts of paint films
	Cosmetics	Test water vapor permeability of cosmetics
	Biodegradable Films	Test water vapor permeability of various sorts of biodegradable films, e.g. starch-based packaging films
