Title:
FILM, LAMINATE, PACKAGING MATERIAL, AND METHOD OF PRODUCING FILM
Document Type and Number:
Japanese Patent JP2022031161
Kind Code:
A
Abstract:
To provide a highly biodegradable vapor-deposited film that is high in biodegradability at room temperature, and also excellent in marine biodegradability, and provide an industrially advantageous laminate that has excellent gas barrier properties even with a small layer constitution by using the vapor-deposited film and is suitable for packaging materials, particularly a food packaging material and a medicine packaging material.SOLUTION: The inventive film has an inorganic vapor-deposited film on at least one surface of a resin layer obtained using a resin composition containing an aliphatic polyester-based resin (A) including a repeating unit derived from an aliphatic diol, and a repeating unit derived from an aliphatic carboxylic acid as main constitutional units. The inventive laminate has a vapor-deposited film on a substrate layer, and a resin layer including a resin composition containing the aliphatic polyester-based resin (A) on the vapor-deposited film.SELECTED DRAWING: None
