Problems solved by technology

In addition, due to the heterogeneity of the paper, the ink penetrates unevenly into the paper, causing mottling, which further degrades the image quality
[0019] However, when further attempts are made to surface-laminate the printed substrate to another thermoplastic polymer layer or film, it has been observed that the adhesion between the printed ink and the outermost protective thermoplastic polymer layer is insufficient

Embodiment Construction

[0032] Thus, the laminated packaging material for food packaging according to the invention comprises a substrate layer on its surface intended to be directed towards the outside of a packaging container made of the packaging material on its first side surface, A precoat for receiving a printed decorative layer of an aqueous pigment-based inkjet printing ink, a pigmented inkjet printed decorative layer, and an outermost thermoplastic polymer layer further laminated to said printed decorative layer are applied in this order to Thereon, wherein the precoat composition comprises a water-soluble polyvalent cationic salt and the salt concentration applied on the substrate surface is 0.02 g / m 2 to 0.1g / m 2 , preferably from 0.02g / m 2 to 0.05g / m 2 dry coating weight.

[0033] According to one embodiment of the invention, said substrate is paper or paperboard constituting the core layer of said laminated packaging material.

[0034] According to a further embodiment, the precoat c...

Abstract

The invention relates to a laminated packaging material for food packaging, comprising a core layer of paper or paperboard, which on a first side intended to be directed towards the outside of a packaging container, has, in the following order, a dry pre-coating for receiving a printed decor of an aqueous, pigment-based, ink-jet printing ink, a pigment-based ink-jet printed ink decor layer and further laminated onto the printed decor layer, a protective outermost layer of a thermoplastic polymer. The invention also relates to a method for manufacturing of the packaging laminate and to a packaging container that is made from the laminated packaging material as well as to a pre-coating composition for use in the laminated packaging material and in the manufacturing thereof.

Description

technical field [0001] The present invention relates to a laminated packaging material for food packaging comprising a paper or paperboard core layer, on a first side intended to be directed towards the outside of the packaging container, with inkjet printing for receiving an aqueous pigment base in the following sequence A dry precoat of a printed decorative layer of ink, a pigment based inkjet printed decorative layer and an outermost thermoplastic polymer layer further laminated to said printed decorative layer. The invention also relates to a method of making the laminated packaging material, and to a packaging container made from the laminated packaging material, and to a precoat combination for use in said laminated packaging material and in the manufacture of a packaging container thing. Background technique [0002] Single-use disposable type packaging containers for liquid food products are usually manufactured from paperboard or cartonboard based packaging laminat...
