Abstract: The invention provides a laminated film. The laminated film includes a polyester substrate film, and a coating layer on/over at least one surface of the substrate film. The coating layer includes a resin composition including a resin having an oxazoline group. The laminated film has an inorganic thin-film layer on/over the coating layer, and a protective layer that has a urethane resin and has an adhesion amount of 0.15 to 0.60 g/m2 on/over the inorganic thin-film layer. The laminated film shows a total reflection infrared absorption spectrum having a ratio P1/P2 ranging from 1.5 to 3.5 wherein P1 is the intensity of a peak having an absorption maximum in a range of 1530±10 cm−1, and P2 is that in a range of 1410±10 cm−1. The laminated film further has an oxygen permeability of 5 ml/m2·d·MPa or less under conditions of 23° C.×65% RH.

Abstract: The present invention provides an environment-responsive laminated film including an inorganic thin film layer and a protective layer in this order on a substrate film layer using a polyester resin recycled from PET bottles. The laminated film has excellent barrier properties and adhesiveness even after a severe wet heat treatment and has less deterioration in appearance of the film even after retorting. The laminated film comprises a substrate film; an inorganic thin film layer on at least one surface of the substrate film; and a protective layer containing a urethane resin on the inorganic thin film layer, wherein (a) the substrate film contains 50% by weight or more of a polyester resin recycled from PET bottles; (b) standard deviation of a haze after retorting the laminated film at 130° C. for 30 minutes is 0.5% or less; and (c) an adhesion amount of the protective layer is 0.5 g/m2 or less.

Abstract: The invention provides a laminated body which contains an environmentally friendly recycled material, has a lamination constitution composed of substantially a single resin type mainly composed of polyester and having a low environmental load, and has required performances such as gas barrier properties, sealability, toughness, and transparency required for a packaging material.
The laminated body is formed by laminating a polyester substrate film containing 50% by weight or more of a polyester resin recycled from PET bottles and a heat sealable resin layer in this order,
wherein the substrate film is a laminated film including an inorganic thin film layer (A) and a protective layer (a) containing a urethane resin on one surface thereof, and
the heat sealable resin layer is formed of a polyester-based resin mainly composed of ethylene terephthalate, and has a piercing strength of 10 N or more and a haze of 20% or less.
