A drug solution filling plastic ampoule having gas, steam and light ray barrier properties, a drug permeation preventing capability and an absorption/adsorption preventing capability, and a production method for the plastic ampoule. The drug solution filling plastic ampoule includes a container body, a fusion-bonded portion which seals a mouth of the container body, and a wrench-off holder tab connected to the fusion-bonded portion. The ampoule is formed from a parison including two or more layers, at least one of which is a functional layer having at least one characteristic property selected from the group consisting of a gas permeation preventing capability, a steam permeation preventing capability, a light ray permeation preventing capability, a drug permeation preventing capability and a drug absorption/adsorption preventing capability.

Drug solution filling plastic ampoule and process for producing the same

A multilayer sealant film for use in the medical field at least comprises as its innermost layer a first layer comprising at least one resin selected from the group consisting of linear low-density polyethylene, low-density polyethylene, polypropylene and polybutene-1, and a third layer comprising an ethylene-vinyl alcohol copolymer and laminated to the outer side of the first layer with a second layer serving as an adhesive layer and comprising a resin containing, as a main component, at least one of an amorphous polyolefin, adherent polyolefin and ethylene-vinyl acetate copolymer. The ethylene-vinyl alcohol copolymer forming the third layer functions as a barrier for preventing contaminants from migrating from outside of the third layer toward the first layer (innermost layer). Further, it is possible to improve the formability of the multilayer film since the difference in density between the resin for forming the first layer and the resin for forming the second layer is set to be 0.02 g/cm or less.

The invention provides a polyolefin drug packaging material characterized in that the content, in the polyolefin, of substances containing 12 to 26 carbon atoms is not more than 150 ppm. The packaging material of the invention is useful because the risk of its reacting with and adversely affecting the drug packaged therewith is minimum.
