Abstract

Problema Proporcionar una película selladora que sea menos probable de que adsorba componentes formados de varios tipos de compuestos orgánicos, tenga excelentes características de sellado térmico a 140 ºC, mientras que tenga una fuerza de sellado térmico baja a 100 ºC y sea menos probable de que las capas de sellado térmico se adhieran entre sí incluso cuando la película se utiliza como una bolsa de empaquetado y el contenido de la misma se caliente en agua hirviendo. Solución Una película selladora que tiene baja adsorción que comprende; la película tiene al menos una capa de sellado térmico que consiste de un componente de poliéster, en donde la película cumple con los siguientes requisitos (1) a (3): (1) una fuerza de sellado térmico de la capa de sellado térmico que se sella térmicamente a otra capa de sellado térmico a 100 ºC y 0.2 MPa durante 2 segundos es 0 N/15 mm o más y 5 N/15 mm o menos; (2) una fuerza de sellado térmico de la capa de sellado térmico que se sella térmicamente a otra capa de sellado térmico a 140 ºC y 0.2 MPa durante 2 segundos es 8 N/15 mm o más y 30 N/15 mm o menos; (3) una densidad de película que incluye todas las capas es 1.20 o más y menos de 1.39.
