Problems solved by technology

[0004] However, it is very difficult to achieve a packaging material that can simultaneously meet the requirements of preventing the transfer of easily oxidizable components and oily components in the patch to the packaging material and the stability of the medicinal ingredients in the patch that are easily affected by oxygen.

preparation example Construction

[0043] In the production of packaging materials, extrusion molding methods known per se can be used. For example, it is possible to form a laminate by performing extrusion molding with a multi-layer multi-die using the number of extruders corresponding to the type of resin. Furthermore, an extrusion coating method, a sandwich lamination method can be used, and a laminate can also be produced by a dry lamination method of a film formed in advance.

[0044] The laminated body can be formed into common three-side or four-side sealed flat bags, gusseted bags (ガセット付パウチ), stand-up pouches, pillow-shaped packaging bags, etc. by bagging, and thus can be made into packaging bags. Bag making can be performed by a known bag making method.

[0045] The patch packaged with the above-mentioned packaging material is composed of a support layer and an adhesive layer, and the adhesive layer is mixed with drugs to allow the drugs to be absorbed through the skin to treat or prevent various dise...

Embodiment 1

[0067] The obtained oxygen-absorbing laminated film was cut into two 7 cm x 7 cm squares, their non-stretched PET film layers were opposed so that the two oxygen-absorbing laminated films were superimposed, and the prepared one sheet was filled inside. The four sides are heat-sealed with a sealing width of 5mm, and a packaging structure with a volume of 2ml is made into the patch.

[0068] The quality change of the patch was evaluated according to the following method. The results are shown in Table 1.

Abstract

An object of the present invention is to provide a packaging material that is capable of long term storage by preventing adsorption or transfer of an easily oxidizable component and an oily component in an adhesive of a patch to the packaging material, and also preventing discoloration and decrease in drug effect due to oxidization. The present invention provides the packaging material for a patch including: an inner layer made of polyethylene terephthalate having heat sealing properties; an oxygen-absorbing layer that includes an oxygen-absorbing resin having an unsaturated alicyclic structure as an oxygen-absorbing part; and an oxygen barrier layer made of aluminum foil as an outer layer.

Description

technical field [0001] The invention relates to a packaging material for an adhesive agent, in particular to a packaging material for an adhesive agent which contains easily oxidizable components and oily components and is easily affected by oxygen. Background technique [0002] Patch preparations, especially percutaneous absorption preparations containing drugs in the adhesive layer, are currently hermetically packaged using airtight packaging materials from the viewpoint of quality maintenance during storage. However, in the case of packaging a patch containing an easily oxidizable component and an oily component in the adhesive, the patch is in contact with the inner surface of the packaging material, and the easily oxidizable component and the oily component are adsorbed or transferred. On packaging materials, the content of easily oxidizable components and oily components in the adhesive changes, resulting in changes in the adhesive properties. Furthermore, it has been...
