摘要:
The present invention relates to a non-foil packaging laminate for liquid food packaging comprising two or more layers of paper or other cellulose-based material, outermost liquid tight, heat sealable layers of polyolefin-based polymers, and barrier layers coated onto the inner side of the first layer of paper or cellulose-based material. The invention also relates to a method for manufacturing the packaging laminate and to a packaging container that is made from the packaging laminate.
摘要:
A packaging laminate (10a) comprising a core layer of paper or carton (11) with through -going holes, openings or slits (11a), a first layer of heat sealable thermoplastic material applied on the outermost side of the packaging laminate (10a), a second layer of heat sealable thermoplastic material (13) applied on the other, innermost side of the packaging laminate (10a), one or more barrier layers (14) applied between the core layer (11) and the innermost thermoplastic layer (13), the thermoplastic material (12,13) and barrier layers (14) all being laminated to each other within the regions of said holes (Ha) to form a membrane of barrier and thermoplastic material layers. A method for manufacturing of the packaging laminate and a packaging container that is made from the packaging laminate.
摘要:
The present invention relates to a non-foil packaging laminate for liquid food packaging comprising a layer of paper or other cellulose-based material (11), outermost liquid tight, heat sealable layers of polyolefin-based polymers (14, 15) and, vapour-deposition coated onto the inner side of the layer of paper or cellulose-based material, an induction heat susceptible metal coating (12). The invention also relates to a method for manufacturing of the packaging laminate, to a packaging container that is made from the packaging laminate and to a method of induction heat sealing the packaging laminate into packaging containers.
摘要:
A low scalping laminate material [24] for a container for food packaging includes a core layer of paper or paperboard [26], a polymeric coating [30] applied to one side of the core layer and a combination of layers [34] disposed on an opposing side of the core layer. The combination of layers includes a first barrier layer [36] disposed adjacent the core layer, a first tie layer [38] adjacent the first barrier layer, a second barrier layer [40] adjacent the first tie layer, a second tie layer [42] adjacent the second barrier layer and a second polymeric coating [44] adjacent the second tie layer. The second polymeric coating is configured for a food contacting surface. The first and second barrier layers are formed from an admixture of an aromatic polyamide resin and polyamide 6, and the first and second tie layers are formed from one of a modified polyethylene and a polyolefin. A carton formed from the low scalping laminate is disclosed.
