Definitions

  • the present invention relates to a water-soluble packaging film made of a polyvinyl alcohol film and a package formed from the water-soluble packaging film.
  • the modified PVA has structural units other than the structural units derived from polyvinyl ester. More specifically, the modified PVA is obtained by saponifying a polymer of a vinyl ester and another unsaturated monomer. Other unsaturated monomers include monomers other than vinyl esters, such as monomers having a carbon-carbon double bond such as a vinyl group.
  • the sulfonic acid group-modified PVA may be one in which a sulfonic acid group is introduced by modification, and is preferably one in which a sulfonic acid group is bonded to a polymer main chain via a linking group.
  • the linking group include an amide group, an alkylene group, an ester group, and an ether group. Of these, a combination of an amide group and an alkylene group is preferred.
  • the above-mentioned (meth) acrylamidoalkanesulfonic acid or a salt thereof may be used as an unsaturated monomer.
  • the saponification degree of PVA is preferably 80 mol% or more and 99.9 mol% or less.
  • the suitable range of the degree of saponification of PVA also differs depending on the presence or absence of modification and the type of modifying group.
  • the unmodified PVA is preferably at least 80 mol% and at most 99.9 mol% as described above, but from the viewpoint of further improving the water solubility, more preferably at least 80 mol% and at most 95 mol%, and at least 85 mol% It is more preferably at most 92 mol%.
  • the water-soluble packaging film of the present invention further contains a plasticizer. Since the water-soluble packaging film contains a plasticizer, it has appropriate flexibility and improves water solubility. And, when used in combination with the water surface diffusing agent, the diffusing property of the above-mentioned agent becomes excellent. Further, the glass transition point is lowered, and the durability at low temperatures is improved.
  • the plasticizer is not particularly limited and includes, for example, polyhydric alcohols such as glycerin, diglycerin, diethylene glycol, trimethylolpropane, triethylene glycol, dipropylene glycol, propylene glycol, and glucose; and polyhydric alcohols such as polyethylene glycol and polypropylene glycol.
  • Examples thereof include ethers, phenol derivatives such as bisphenol A and bisphenol S, amide compounds such as N-methylpyrrolidone, compounds in which ethylene oxide is added to polyhydric alcohols such as glycerin, pentaerythritol and sorbitol, and water. These may be used alone or in combination of two or more.
  • plasticizers glycerin, diglycerin, trimethylolpropane, polyethylene glycol, polypropylene glycol, triethylene glycol, dipropylene glycol, and propylene glycol are preferred from the viewpoint of improving water solubility and drug diffusibility.
  • diglycerin and trimethylolpropane are particularly preferable from the viewpoint of suppressing stickiness under high temperature and high humidity and improving workability. Diglycerin and trimethylolpropane may be used alone or in combination.
  • the molecular weight of the plasticizer is preferably 90 or more, more preferably 120 or more, and further preferably 130 or more. When it is 90 or more, the water solubility and the diffusibility of the drug can be easily improved. Moreover, by setting it to 120 or more, it is easy to suppress stickiness under high temperature and high humidity and to improve workability.
  • the molecular weight of the plasticizer is preferably 1200 or less, more preferably 1000 or less, and further preferably 500 or less.
  • the content of the water surface diffusing agent is preferably 0.9 parts by mass or more, and more preferably 2 parts by mass or more.
  • the content of the water surface diffusing agent is preferably 9 parts by mass or less, more preferably 6 parts by mass or less, and more preferably 4.5 parts by mass or less, from the viewpoint of improving the mechanical strength while improving the diffusibility of the drug. More preferred.
  • the present invention by using the above-mentioned modified PVA, even if the content of the water surface diffusing agent is relatively small, it is easy to make the diffusing property of the drug excellent.
  • the method of using the packaging material as a bag is not particularly limited.
  • a bag may be formed by folding a single film and bonding the periphery thereof, or by laminating two films and bonding the periphery to form a bag. Or a bag in another way.
  • the method for bonding the film is not particularly limited, and the film may be bonded by heat sealing, an adhesive, or the like, but heat sealing is preferable.
  • the temperature of the heat sealing is not particularly limited, but is, for example, 70 ° C or more and 160 ° C or less, and preferably 80 ° C or more and 150 ° C or less. In general, when heat sealing is performed, particularly when heat sealing is performed under high temperature and high humidity (for example, at 30 ° C.
