破袋は認められなかった。From Tables 1 and 2, it can be seen that the strength is improved by increasing the water content of the water-soluble film. Especially, the water content of the water-soluble film
When the amount is 5 parts by weight or more with respect to 00 parts by weight, good results are obtained, and particularly when the amount is 7 parts by weight or more, no bag breakage is observed even at low temperature storage.
