Packaging laminate, method for manufacturing of the packaging laminate and packaging container produced there from

摘要

The present invention relates to a non-foil packaging laminate for liquid food packaging comprising a core layer of paper or paperboard, outermost liquid tight, heat sealable layers of polyolefin and, applied onto the inner side of the layer of paper or paperboard, an oxygen gas barrier layer formed by liquid film coating of a liquid gas barrier composition and subsequent drying, the liquid composition containing a polymer binder dispersed or dissolved in a liquid medium. The laminate further comprises a layer of a polyolefin-based matrix polymer with inorganic filler particles distributed therein and inorganic particles dispersed also in the gas barrier layer from the liquid gas barrier composition. The invention also relates to a method for manufacturing of the packaging laminate and to a packaging container made from the packaging laminate.
