To provide a standing pouch for storing a pyrethroid insecticidal spray liquid which pouch does not allow a reduction in the concentration of a drug in the pouch or allows a slight reduction in the concentration to the extent that affects no practical application of the drug even when filled with a spray liquid containing a low-concentrated pyrethroid insecticide, and retains flexibility making the pouch foldable as a basic performance of a standing pouch.
The standing pouch is of a multilayer structure comprising an innermost layer of a low-density polyester layer, an intermediate layer, and an outermost layer of a polyethylene terephthalate layer. The standing pouch includes at least one resin layer containing an inorganic-layer-like compound as the intermediate layer, the resin layer containing the inorganic-layer-like compound and a high hydrogen-bonded resin at an aspect ratio of 200 to 3,000 and a volume ratio of 5/95 to 50/50.
