Definitions

  • the eighth aspect of the present invention is defined as follows. That is, in the aqueous dispersion defined in any of the fifth to seventh aspects, the aqueous dispersion medium contains partially saponified polyvinyl alcohol as a dispersant in an amount of 2.0 to 10.0 mass with respect to the dispersoid. % Is blended. When the partially saponified polyvinyl alcohol of the above formulation is used as the dispersant, it has been confirmed that both heat sealability and blocking resistance are compatible.
  • the compounding ratio of the polylactic acid and the plasticizer and the carbana wax in the sheet material can be 6 to 14% by mass (the 19th aspect).
  • high block king resistance 50 ° C. or higher
  • practical heat-sealing properties the 20th aspect.
  • Examples of the oil resistance improving aid for the biodegradable resin film include styrene-acrylic copolymer, starch and wax.
  • the styrene-based monomer of the styrene-acrylic copolymer is not particularly limited, and for example, styrene, ⁇ -methylstyrene, ⁇ -methylstyrene, 2,4-dimethylstyrene, ⁇ -ethylstyrene, ⁇ -butylstyrene, 4 -Methylstyrene, vinyltoluene and the like can be mentioned.
  • starch examples include modified starches such as corn starch, potato starch, tapioca starch, oxidized starch, phosphate starch, etherified starch, dialdehyded starch and esterified starch.
  • waxes such as natural wax and synthetic wax can be used.
  • Natural waxes include plant-based natural waxes such as candelilla wax, rice wax, wood wax, and jojoba solid wax, animal-based natural waxes such as honey wax, lanolin, and whale wax, and mineral-based natural waxes such as montan wax, ozokelite, and selecin. , Paraffin wax, microcrystallin wax, petrolatum wax and other petroleum-based natural waxes and the like.
  • Polylactic acid Luminy LX930 manufactured by Total Corbion Co., Ltd.
  • DAIFATTY-101 Mixed group dibasic acid ester serosol 524 manufactured by Daihachi Chemical Industry Co., Ltd .: 30% by mass carnauba wax emulsion hydrin W-188 manufactured by Chukyo Yushi Co., Ltd .30: 30 mass% manufactured by Chukyo Yushi Co., Ltd.

  • the blending amount of carnauba wax with respect to polylactic acid is preferably 1% by mass or more and 14% by mass or less.
  • the blocking resistance is poor, and when it exceeds 14% by mass, the effect of improving the blocking resistance can be sufficiently obtained, but under the temperature condition of 130 ° C. It can be seen that the heat-sealing property is not exhibited and the processability is poor.
