Abstract: A unit portion pack is made from two webs, at least one of which is a laminate (2) having layer (4) of tear resistant material, such as polyester film, and a layer (6) of rupturable material, such as aluminum foil. The two webs (2, 26) are bonded together by way of heat seals, (38, 40) to define a plurality of cavity-forming regions (34) in each of which a single pill (36) or other solid product item is received. A longitudinally extending score or slit line (10) extends along each longitudinally arranged row of regions (34) inwardly of the peripheries of the regions. The pill (36) is released by manipulating the pack such that the score or slitline is located on or outboard of the periphery of the pill by movement of the latter. The area of the cavity-forming region on the other side of the score or slit line to the pill is then squeezed to fracture the rupturable material at the score or slit line. This forms a dispensing opening through which the pill may be pushed.

Abstract: In a method of producing uniaxially oriented polymer material, particularly a uniaxially oriented film, from a high density polyethylene, in which the material is put under tension and is drawn from a transverse heated portion with a draw ratio of 5:1 or higher (preferably 7:1 to 20:1), the drawing temperature is selected to be between 80.degree. C. and 110.degree. C., and preferably below 105.degree. C., whereby excellent gas barrier characteristics are obtained in the drawn material.
