Abstract

"MATERIAL DE ACONDICIONAMENTO LAMINADO, E, MéTODO PARA FABRICAR O MESMO". Material de acondicionamento laminado, na forma de uma lâmina, faixa ou folha contínua, do qual se produz uma embalagem estável na forma, impermeável a fluido mediante formação de dobras, termoformação ou outro processo mecânico para configuração do material. O material tem uma primeira e uma segunda camada extrusada; a primeira camada inclui um primeiro material termoplástico selecionado do grupo que consiste de polímeros com base em propileno e, preferivelmente, um homopolímero de propileno ou um copolímero obtido de propileno e etileno e inclui 5 % a 85 % em peso de uma carga mineral inorgânica, preferivelmente dolomita e talco. A segunda camada inclui um segundo material termoplástico selecionado do grupo que consiste de polímeros com base em etileno, e preferivelmente, polietileno de baixa densidade (LDPE). De acordo com a presente invenção, a primeira camada e a segunda camada são laminadas diretamente uma na outra e nenhum adesivo é necessário entre elas."LAMINATED PACKAGING MATERIAL, AND, METHOD FOR MANUFACTURING THE SAME". Laminated packaging material, in the form of a blade, strip or continuous sheet, from which a stable packaging is produced in the form, impermeable to fluid through the formation of folds, thermoforming or other mechanical process for configuring the material. The material has a first and a second extruded layer; the first layer includes a first thermoplastic material selected from the group consisting of propylene-based polymers and, preferably, a propylene homopolymer or a copolymer obtained from propylene and ethylene and includes 5% to 85% by weight of an inorganic mineral filler, preferably dolomite and talc. The second layer includes a second thermoplastic material selected from the group consisting of polymers based on ethylene, and preferably low density polyethylene (LDPE). According to the present invention, the first layer and the second layer are laminated directly to each other and no adhesive is needed between them.
