The packing laminated wood, the packing container which is produced from the production method, and its packing laminated wood

摘要

Being the packing laminated wood, core layer of the paper or the cardboard make which possesses the hole which it penetrates (11), the thermoplastic physical layer which is provided on the surface outside one of core layer (12), it is provided on the surface inside one more of core layer, the aluminum foil which is connected to core layer center of the thermoplastic substance (14) by (13), the first gluing formation layer which is provided on the surface inside the aluminum foil (the 15-1), adjoining to first gluing formation layer, it is provided, it includes the substance which gives barrier characteristic at the same time vis-a-vis the movement of the fatty acid of freeThe metallocene polyethylene (m-PE) including intermediate formation layer (the 15-2), mainly most formation layer inside (the 15-3) it includes, at the same time 2 layer of the thermoplastic substance (12 and 14), is sealed mutually in the territory of the hole and the packing laminated wood which forms the aluminum foil and the membrane which consists of the thermoplastic substance (10) is offered. This packing laminated wood has the seal quality which is improved, at the same time, is produced from this laminated wood for example sterile mothballing of the fruit juice as a purpose, was improved to the packing container which has opening expedient, or gives packing integrity and the opening characteristic which are maintained. This opening expedient when opening, removes the membrane which consists of the aluminum foil and the layer where the thermoplastic substance is laminated from the territory of the hole of core layer. The substance which is desirable, gives the barrier characteristic for the movement of the fatty acid of free cycloolefin copolymer (COC) and/or is the bulking agent.
