Abstract

"PELìCULA TUBULAR E PROCESSO PARA FABRICAçãO DA MESMA". Uma película tubular para envolver alimentos. A película tubular consiste de um material que tenha sido regenerado a partir de uma solução de viscose. O material tubular é esticado longitudinalmente por +8 até +40 por cento e esticado transversalmente por -20 até +40 por cento enquanto úmido e o esticamento é mantido durante a secagem, os mencionados esticamentos longitudinal e transversal sendo suficientes para se obter um aumento de área superficial de pelo menos 10 por cento do ponto de regeneração. Em geral, o material tubular possui uma espessura de parede de cerca de 60 até cerca de 90 por cento do mesmo material tubular exceto sem o esticamento combinado. A invenção inclui também o processo de fabricação do material tubular pelo esticamento do material tubular regenerado enquanto úmido e mantendo o esticamento durante a secagem.
