Therefore, the film should be used as soon as possible when opened. The recommended temperature is 15 -25ºC with humidity less than 60%RH after opening.With original sealed package, and stored as mentioned above, the storage time can be as following: Al metallized film: 12 months from the delivery date. Al/Zn Alloy metallized film: As zinc is quite unstable , the storage period (from delivery date) depends on the resistance of the film:≤10 Ohm/sq: 6 months 10 ~30Ohm/sq: 3 months >30Ohm/sq: 1monthAppliactions of Metallised filmCompany HonorOur company has obtained ISO9001 quality management system certificate, ISO14001 environment management system certificate, OHSAS18001 occupational health and safety management system certificate.A Tour of metallised film plant Metallised film MetalliserMetallised Film slitterOur Advantages: Aim : Quality first, Customer formost, knight service, Sustainable improvement, to be reliable supplier of metallised film.  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
