A highly transparent and dimensionally stable glassine, which is used as window material for envelopes and for the manufacture of medicine bags. Thanks to its high transparency and dimensional stability and the fact that it is free of chlorine and acid, it is well suited for windowing material for envelopes, for the manufacture of medicine bags, as pouches for negatives and as protection for stamps in stamp albums.
ECHO® WIN is 100% recyclable, so it can either be added to the compost or the waste paper.
Only an envelope with a glassine window is 100% paper!
