  • Patent Document 2 discloses that the base material layer is composed of a laminate in which at least a base material layer, an adhesive layer, a metal layer, and a sealant layer are sequentially laminated, and the base material layer has a stress at 50% elongation/5% elongation in the MD direction. Good formability can be obtained by setting the sum (A+B) of the stress value A at 50% elongation/stress value B at 5% elongation in the TD direction to a specific range. Disclosed.

Furthermore, it is excellent in dimensional accuracy reduction and warpage resistance after molding due to springback, resulting in excellent dimensional accuracy in molding processing, and furthermore, by using carbon-neutral raw materials, it can also contribute to reducing environmental impact.

  • the biomass-derived polyamide resin used in the present invention is preferably one or more polyamide resins selected from the group consisting of polyamide 11, polyamide 410, polyamide 610, and polyamide 1010.
  • Polyamide 410 is a polyamide resin having a structure in which a monomer having 4 carbon atoms and a diamine having 10 carbon atoms are copolymerized.
  • polyamide 410 is made of sebacic acid and tetramethylene diamine.
  • sebacic acid is preferably one made from castor oil, a vegetable oil.

  • Polyamide 1010 is a polyamide resin having a structure in which a diamine having 10 carbon atoms and a dicarboxylic acid having 10 carbon atoms are polymerized.
  • 1,10-decanediamine (decamethylene diamine) and sebacic acid are used for polyamide 1010. Since decamethylene diamine and sebacic acid are monomers obtained from castor oil, they are desirable from the viewpoint of carbon neutrality.

If the stretching ratio in the MD preliminary stretching is too low, it is difficult to obtain the effect of improving hygroscopic distortion, which will be described later. On the other hand, by setting the preliminary stretching ratio to 1.15 times or less, the progress of oriented crystallization is prevented, and the stretching stress in the subsequent MD main drawing becomes too high and breakage occurs during the main drawing or TD drawing.

When the stretching temperature in the TD direction exceeds 140° C., not only the film formability deteriorates, but also the orientation of the obtained film in the TD direction becomes weak, so that the moldability may deteriorate.
