Abstract
El invento se refiere a un substrato de una película degradable pero que no es sellable por calor se convierte a una película sellable por calor recubriéndola en forma discontinua, con una formulación termoplástica no degradable o degradable. La degradabilidad deseada del substrato se determina por la forma de descarte propuesta para el producto en el que se usará la película. La discontinuidad del recubrimiento expone el substrato degradable, haciendo que dicho substrato sea suceptible a la degradación causada por microorganismos o por medios hidrolizantes. La invención se lleva a cabo adhiriendo un recubrimiento termoplástico discontinuo no degradable o degradable a uno o ambos lados de una pelicula bio-degradable o hidrolizable, a fin de obtener una película sellable por calor cuya capacidad inherente a la degradación no está comprometida y cuyo régimen de degradación no está materialmente afectado. Las películas según está invención puede ser compinentes pérmeables o impermeables de productos medicinales y de consumo descartables y materiales de envase para dichos productos.The invention relates to a degradable but not heat sealable film substrate is converted to a heat sealable film by coating it discontinuously with a non-degradable or degradable thermoplastic formulation. The desired degradability of the substrate is determined by the proposed form of discard for the product in which the film will be used. The discontinuity of the coating exposes the degradable substrate, making said substrate susceptible to degradation caused by microorganisms or by hydrolyzing means. The invention is carried out by adhering a non-degradable or degradable discontinuous thermoplastic coating to one or both sides of a biodegradable or hydrolyzable film, in order to obtain a heat sealable film whose inherent degradation capacity is not compromised and whose regime degradation is not materially affected. The films according to this invention can be permeable or waterproof components of disposable medicinal and consumer products and packaging materials for said products.
