Abstract: A packaging material is formed by a substrate, and an inner sealing layer comprising a polyolefin layer and an aqueous dispersion-type polyester resin layer successively disposed on the substrate. The aqueous dispersion-type amorphous polyester resin layer contains an anionic surfactant or an amphoteric surfactant and is substantially free from an organic solvent having a boiling point of at most 100° C. The thus-formed packaging material is excellent in aroma-retentivity, aroma non-adsorptivity, particulate non-adhesion, low residual solvent and sealability. The packaging material is also free from environmental problem and is therefore suitable as a packaging material for particulate medical supplies and health foodstuff.

Abstract: A press-through pack and a sealing sheet for use in the same capable of easily taking out solid material such as tablet or the like contained storage recesses by only pushing action of fingers. The pack comprises an accommodation body (2) with plural storage recesses (2a) defined by sheet like portions (2b) for a containing solid material therein and sealing sheet (5). The sealing sheet (5) is made of such material that a recess (2a) in which solid material (T) contained, is partly ruptured without causing floating and peeling at the adhesion portion of the adhesive layer (4) and the sheet like portions (2b) when pushing the projecting portion (2c) of the outer side of the recess (2a) with fingers, whereby the solid material (T) contained in the recess (2a) is easily taken out and the sealing sheet is partially bonded to the accommodation body at sheet like portions (2b) in a manner that the whole parts of sealing sheet (5) is easily peeled off from the accommodation body.
