Abstract: A multilayer laminated film for packages, constituted by a first layer made of plastic material and by at least one second layer made of material chosen among plastic material, metallic material, paper-like material or equivalent materials; each layer is coupled to the adjacent layer by means of an intercalated layer of adhesive material. The multilayer laminated film has, on at least one face of the more rigid layer of plastic material, a plurality of continuous, parallel, side-by-side incisions, which are adapted to facilitate a reduction of the breaking load at right angles to the direction of the incisions. The incisions are obtained by removing material and affect only partially the thickness of the more rigid layer.

Abstract: A multilayer film for the production of flexible packaging for thermal treatment has a plastic layer as outer layer and a sealable layer as inner layer, and middle layers. The outer layer, the inner layer and the middle layers are coextruded to form a biaxially oriented film, and the multilayer film has a maximum degree of dimensional change of 2% at most when exposed to temperature.

Abstract: In a process for continuously manufacturing a flexible laminate for food packagings at least one plastic film and at least one further plastic film, metal foil or paper as laminate layers are continuously coated with an adhesive and brought together to form a laminate. Subsequently, the laminate is continuously irradiated in line in a microwave irradiation station in order to cure the adhesive. With the process according to the invention the curing time is significantly reduced in comparison to the standard thermal energy used nowadays and provided by a curing room warmed at 40-45° C.
