New DEVEX film is composed of total 11 layer films (PET, PA, Aluminum, PE, etc) with thickness around 75um thinner than
Aluminium-plastic(multi-layer)gas sampling bags and better elasticity,can't become hard-brittle when cold like
Aluminium-plastic(multi-layer)gas sampling bag, it has superb strength and low permeability,meanwhile it possesses excellent
chemical inertness and stability.Especially when Aluminium-plastic(multi-layer)gas sampling bag cannot meet the requirements and
using fluorine polymer cost too much,DEVEX gas sampling bag is the best choice.Being detected by authoritative organizations DEVEX
film is superior to Aluminium-plastic composite film,so DEVEX gas sampling bags are of the most value for money at home and
abroad,and widely used by customers abroad.
Features:•composed of total 11 layer films
•very low background,little contamination and good elasticity
•superb strength and low permeability
•excellent chemical inertness and stability
•wide range of applications
•low price and good value for money
•Normal Aluminium-plastic composite film is glued of solvent adhesive,can volatile alarge number of organic volatile impurities
that can pollute the sample gas no doubt,DEVEX film is glued of environmental protection adhesive,precipitationamount of organic
volatile chemicals(VOCs)by inner layers is extremely low,thereby avoid sample gas inside the bag being polluted and prevent the
interference of analysis data.The organic solvent remnant amount of DEVEX film is 0.1mg~0.3mg/㎡,which is 5% of Aluminium-plastic
composite film,so DEVEX film is the ideal high performance substitute for Aluminium-plastic composite film.
•Standard Devex(multi-layer) Gas Sampling Bag Sizes:0.5L,1L,2L,3L,4L,5L,8L,10L,15L,20L,30L, 40L~6000L or customized size.
