Provided are a film and an electric device comprising the same. The film comprises at least one modified polyolefin resin layer. A resin forming the modified polyolefin resin layer comprises 1-100% of modified polyolefin resin. A main chain in the modified polyolefin resin is an ethylene--olefin copolymer. A grafted branched chain in the modified polyolefin resin is selected from a compound formed by a vinyl monomer comprising one or more of anhydride group, hydroxyl, ester group, carbonyl, acylamino, pyridyl, epoxy, pyrrolidonyl and glycidyl. A molecular weight of the grafted branched chain is 150-8000 g/mol. The film prepared from the modified POE layer with the main chain and the grafted branched chain has excellent anti-PID performance. The layers have a better adhesive property without a laminated interface therebetween. The co-extruded film further has an excellent water vapor barrier property, a relatively high insulating property and a relatively high light transmittance.

The present invention comprises a single-component binder for heat-sealing applications which can be used for the sealing of polyester foils, in particular of polyethylene terephthalate foils (PET foils) with respect to containers made of polystyrene, of PVC, and of polyester. These polyesters can in particular be polyethylene terephthalate (PET) or polylactic acid (PLA). The binders here feature not only good seal seam strengths but also in particular good transparency and excellent application properties. A substantive aspect of the invention is that the sealing can be achieved without addition of adhesion promoters, in particular without addition of adhesion promoters based on polyvinyl chloride (PVC) or on polyester, and that barrier properties and sealing properties achieved in respect of containers made of PS and of PET are nevertheless at least comparable with, and sometimes better than, those achieved with heat-sealing systems already marketed.
