Embodiment Construction

[0043] Such as figure 1 As shown, the present invention is a coated kraft cardboard, which consists of a coating layer 1, a surface layer 2, a core layer 3, a bottom layer 4 and a starch sizing layer 5.

[0044] The coating layer 1, the surface layer 2, the core layer 3, the bottom layer 4 and the starch sizing layer 5 are sequentially stacked together. The surface layer 2 is bleached chemical wood pulp, wherein bleached chemical hardwood pulp accounts for 20%-80%, and bleached chemical softwood pulp accounts for 20%-80%; the core layer 3 is mixed pulp, wherein natural color wood pulp Pulp accounts for 30%-70%, and mechanical wood pulp accounts for 30%-70%. The bottom layer 4 is 100% natural color wood pulp.

[0045]The main components of the coating layer 1 are calcium carbonate, china clay and latex, and the mass proportions of each component are 40-60%, 30-50%, 5-20%, and the remaining components are 5-10%. The remaining components are one or more of water-retaining agent...

Abstract

The invention discloses coated kraft paper and a production technology thereof. The coated kraft paper comprises a coated layer, a surface layer, a core layer, a bottom layer and a starch gluing layer, wherein the coated layer, the surface layer, the core layer, the bottom layer and the starch gluing layer are sequentially stacked together; the surface layer is bleached chemical wood pulp; the bleached chemical wood pulp comprises the following ingredients in percentage by weight: 20%-80% of bleached chemical hardwood pulp and 20%-80% of bleached chemical needle pulp; the core layer is mixed pulp; the mixed pulp comprises the following ingredients in percentage by weight: 30%-70% of ecru pulp and 30%-70% of mechanical pulp; and the bottom layer is 100% of ecru pulp. Because the coated kraft paper is manufactured by a three-layered net, 100% of native wood pulp is used, a front surface of the coated draft paper is a coating layer, the back surface of the coated draft paper is the starch gluing layer, the proportion of long fibers and short fibers of the pulp is reasonable, an efficient technological control means is adopted, and the strength of paper and the tenderness of paper surfaces can be guaranteed simultaneously.

Description

technical field [0001] The invention relates to the field of papermaking, in particular to a coated kraft cardboard and a production process thereof. Background technique [0002] Cluster packaging, also known as multipack, is a combination of multiple products packaged as an independent sales unit. Through the bundled packaging of products, the sales of products can bring many benefits: [0003] 1. Stimulate consumers' buying enthusiasm, and the large-area shelf performance has attracted consumers' attention. [0004] 2. Convenience in price management. The price reduction of a single product is often irreversible. After consumers remember the low unit price, it is difficult for them to accept the so-called normal price. However, combined with the price promotion of cluster packaging, the unit price of a single product can be protected and the price system can be maintained. [0005] 3. Establishment of brand image. A good cluster packaging can enhance the brand image....
