    • In the manufacture of packing containers by means of folding of laminate in the form of sheets or of a web of the type which comprises a relatively thick carrier layer (2) of paper or cardboard and a gas-tight, thin metal foil (5) the laminate is subjected to stresses which, particularly within folding regions comprising multiple material thicknesses, may be so strong that crack formations occur in the metal foils protecting against gas which are sensitive to tension, thus entailing the risk of the intended gas barrier characteristics of the packing container being impaired or wholly lost. To counteract this risk the packing laminate is provided with a layer (6) of ethylvinyl alcohol laminated between the metal foil (5) and the carrier layer (2) which for one thing is mechanically sufficiently durable to withstand the external stresses during the folding of the laminate, and for another has sufficiently good gas barrier properties to compensate for the loss in gas tightness which thus may arise if the integrity of the metal foil (5) is lost during the manufacture of the container. Preferably the laminate is provided also with a further layer (7) of a material permeable to moisture which is laminated between the ethylvinyl alcohol layer (6) and the carrier layer (2) and which is adapted to let through moisture which from the liquid-filled inside of the container might be able to penetrate into the ethylvinyl alcohol layer (5) through such crack formations in the metal foil (5). As a result the moisture content in the ethylvinyl alcohol layer (6) can be kept at a sufficiently low level so as not to have a negative effect on the gas barrier characteristics of the ethylvinyl alcohol layer (6) which otherwise diminish with increasing moisture content.

    • A sliding member is provided which comprises a base body made of a firmly entangled and collapsed metal fine wire, with the voids formed between the metal fine wires constituting the metal mesh being filled compactly with a heat resistant material, the sliding surface of the base body being formed into a smooth surface with either a lubricant that fills a number of small holes formed in the heat resistant material as well as covering the surface thereof or the lubricant and the metal fine wires being exposed. A manufacturing method of the same is also disclosed which basically comprises the steps of preparing a metal mesh as a reinforcing material, preparing a sheet-like heat resistant material with a plurality of small holes being formed through the thickness, applying a lubricant on the sheet-like heat resistant material in a given thickness so as to simultaneously fill the small holes, putting the sheet-like heat resistant material on the metal mesh to provide a laminate in which the lubricant is directed towards the sliding surface to be formed, convoluting the laminate about a cylindrical mandrel so as to represent a cylindrical preform and putting the preform in a metal die to axially compress it to provide the final product.
