description | filme coextrudado compreendendo pelo menos 3 camadas e seu uso. a presente invenção resolve os problemas da técnica através de um filme coextrudado compreendendo pelo menos 3 camadas, caracterizado por compreender 50 a 80% em espessura na camada interna (a) compreendendo polietileno ou polipropileno, 10 a 25% em espessura nas camadas externas (b) compreendendo uma mistura de pelo menos dois copolímeros em bloco de estireno-butadieno, em que a dita mistura de copolímeros em bloco compreende entre 5 a 20% de um copolímero em bloco elastomérico termoplástico e entre 80 a 95% de um copolímero em bloco termoplástico. os ditos filmes podendo ser usados como filmes para embalagens de bala e quando mono-orientados como embalagens termos encolhíveis.
The present invention solves the problems found in the prior art by means of a co-extruded film comprising at least three layers, and characterised in that the inner layer (A) made of polyethylene or polypropylene accounts for 50-80% of the thickness thereof, the outer layers (B) made of a mixture of at least two styrene-butadiene block copolymers account for 10-25% of the thickness thereof, and in that the mixture of block copolymers comprises 5-20% elastomeric thermoplastic block copolymer and 80-95% thermoplastic block copolymer. These films can be used for wrapping candy, and when they are monoaxially oriented they can be used as heat-shrinkable packaging. |
