摘要

"Multi-component structure, methods for cooking a food product, for joining a first layer to a second layer in a film, and to improve the adhesion between a first layer or structure comprising a polymer of vinylidene chloride and a second layer or structure c Ontu00edgua and use of a composition.The present invention includes a multi-component structure comprising at least two components having a layer of an adhesive layer directly between the mooring or both, the layer of mooring comprising at least a copolymer of olefin unsaturated ester and at least one fotoinicia Pain and optionally a crosslinking enhancer.The layer is preferably irradiated with sufficient mooring actinic radiation to result in a resistance of accession intercamadas increased between the two components compared with the resistance of accession intercamadas before treatment with actinic radiation, or between the Components having a layer of mooring of the same composition except that without a photoinitiator and enhancerCrosslinking added. Without a photoinitiator, optionally cross-linking radiation enhancer, and the accession intercamadas of components is preferably less than 55 n / m.At least one of the components (the first component or layer) preferably comprises a halopolu00edmero, more preferably a vinylidene chloride polymer, more preferably at least a preponderance of a polymer of vinylidene chloride.In another implementation, at least one component exhibits resistance to join intercamadas similar to polymer of vinylidene chloride. The structure optionally is or includes such structures in the form of a film, a bag, or a multi-layer packaging, coated or composite pipe, or other structure having more than one component.The layer of the mooring is advantageously irradiated with a quantity of UV effective to increase the resistance of adhesion between the first and second components.
