气体隔离热封复合膜和包括其的真空绝热板

Gas-barrier heat-seal composite films and vacuum insulation panels comprising the same
Abstract:
A gas-barrier heat-seal composite film is provided. The gas-barrier heat-seal composite film includes a heat-seal layer including very low density polyethylene (VLDPE), low density polyethylene (LDPE), linear low density polyethylene (LLDPE), high density polyethylene (HDPE), metallocene polyethylene (mPE), metallocene linear low density polyethylene (mLLDPE), ethylene vinyl acetate (EVA) copolymer, ethylene-propylene (EP) copolymer or ethylene-propylene-butene (EPB) terpolymer, and a gas-barrier layer formed on the heat-seal layer, wherein the gas-barrier layer includes a plurality of composite layers, each including a polymer substrate and a single layer or multiple layers of metal or oxide thereof which is formed on one side or both sides of the polymer substrate, and the polymer substrate includes uniaxial-stretched or biaxial-stretched polyethylene terephthalate (PET), polybutylene terephthalate (PBT), polyimide (PI), ethylene/vinyl alcohol (EVOH) copolymer or a combination thereof. The invention also provides a vacuum insulation panel including the composite film.
