Abstract

Se refiere a películas poliméricas termoplásticas utiles para empaquetar productos alimenticios y otros productos lácteos y más específicamente en el campo de las películas termoplásticas poliméricas de formacion térmica, es decir, que puedan ablandarse mediante la aplicacion de calor, deformarse para lograr una forma deseada, y enfriarse. Una estructura de película termoplástica que tiene al menos dos capas que comprende: (a) una primer capa que comprende un polímero o mezcla de polímeros seleccionados del grupo que consiste de poli(propileno), poli(etileno) de alta densidad, poli(acrilonitrilo), PVC, PET, o HIPS; y (b) una segunda capa selladora que comprende un polímero sellador seleccionado del grupo que consiste de poli(etileno) lineal de baja densidad, poli(etileno) de baja densidad o un copolímero de acetato de vinil etileno y un aditivo de separacion de queso. Una estructura rígida realizada a partir de dicha película, termoplástica. Dicha estructura rígida en forma de envase de 4'' X 9'' x 2, 5''. Una estructura de película termoplástica de cinco capas que comprende una primer capa de un polímero seleccionado a partir de un copolímero de alcohol de vinil etileno o dicloruro de polivinilideno; una segunda capa que comprende una poli(olefina) modificada de anhídrido maleico donde dicha poliolefina se selecciona del grupo que consiste de polietileno de alta densidad, polietileno de baja densidad, polietileno de baja densidad lineal, copolímero de acetato de vinil etileno o poli(propileno) y donde dicha segunda capa está dispuesta en contacto con dicha primera capa; una tercera capa que comprende una poli(olefina) modificada de anhídrido maleico donde dicha poliolefina se selecciona del grupo que consiste de polietileno de alta densidad, polietileno de baja densidad, polietileno de baja densidad lineal, copolímero de acetato de vinil etileno de poli(propileno) y donde dicha tercera capa está dispuesta en contacto con dicha primera capa y opuesta a dicha segunda capa; una cuarta capa que comprende un polímero seleccionado del grupo que consiste de poli(propileno), poli(etileno) de alta densidad, PVC, PET; poli(acrilonitrilo) o HIPS donde dicha cuarta capa está dispuesta en contacto con dicha segunda capa; y una quinta capa que comprende un polímero seleccionado del grupo que consiste de LLDPE, LDPE o EVA donde dicha quinta capa está dispuesta en contacto con dicha tercera capa y donde dicha quinta capa contiene un aditivo de separacion de queso.It refers to thermoplastic polymer films useful for packaging food products and other dairy products and more specifically in the field of thermally formed polymer thermoplastic films, that is, they can be softened by heat application, deformed to achieve a desired shape, and cool down. A thermoplastic film structure having at least two layers comprising: (a) a first layer comprising a polymer or mixture of polymers selected from the group consisting of poly (propylene), high density poly (ethylene), poly (acrylonitrile) ), PVC, PET, or HIPS; and (b) a second sealing layer comprising a sealing polymer selected from the group consisting of linear low density poly (ethylene), low density poly (ethylene) or a copolymer of vinyl ethylene acetate and a cheese separating additive . A rigid structure made from said thermoplastic film. Said rigid structure in the form of a 4 '' X 9 '' x 2, 5 '' container. A five layer thermoplastic film structure comprising a first layer of a polymer selected from a copolymer of vinyl ethylene alcohol or polyvinylidene dichloride; a second layer comprising a modified poly (olefin) of maleic anhydride wherein said polyolefin is selected from the group consisting of high density polyethylene, low density polyethylene, linear low density polyethylene, vinyl ethylene acetate copolymer or poly (propylene ) and wherein said second layer is arranged in contact with said first layer; a third layer comprising a modified maleic anhydride poly (olefin) wherein said polyolefin is selected from the group consisting of high density polyethylene, low density polyethylene, linear low density polyethylene, polyvinyl ethylene vinyl acetate copolymer ) and wherein said third layer is arranged in contact with said first layer and opposite said second layer; a fourth layer comprising a polymer selected from the group consisting of poly (propylene), high density poly (ethylene), PVC, PET; poly (acrylonitrile) or HIPS where said fourth layer is disposed in contact with said second layer; and a fifth layer comprising a polymer selected from the group consisting of LLDPE, LDPE or EVA where said fifth layer is arranged in contact with said third layer and where said fifth layer contains a cheese separating additive.
