Patent KR-910009515-B1 (KR)
Title: Flexible packing laminate in the form of sheet or of a web and packing conteines from the laminate
Inventor: PRISK PETER
IPC: B32B15/08
Filed: 1988-11-28
Granted: 1991-11-21
Abstract: 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 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 on 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 ethylvinylalcohol layer (6) which otherwise diminish with increasing moisture content.

Granted: 1995-03-08
Abstract: A hot compress structure is produced by sealing a heat generating compsn. which generates heat in the presence of air into a flat bag-like member whose one side is made of a gas-permeable film and which has no open portion. A wet compress layer is disposed on the other surface of the flat bag-like member. The moisture permeability of the gas-permeable film according to an ASTM method (E-96-80D) is limited to 100-400 g/m2.24 hrs. so that when the structure is put on the human body in close contact, mild heat of the heat generating compsn. can be transmitted uniformly to the entire surface of the skin through the wet compress layer. Keeps a safe temp. at which no low temp. burn occurs for a long period, and moreover promotes local blood circulation and improves local metabolism.
