Double-layered composite package material

Abstract

The double-layered composite package material is one kind of packing and printing material, and consists of color printed plastic film layer and paper layer. It features that the color printed plastic film layer has its color printed side facing the paper layer and is adhered to the paper layer. The present invention is superior to available technology in that the combination of color printed plastic film layer, which may be printed in intaglio printing, and paper layer results in lowered cost and raised product quality.

Description

technical field [0001] The invention belongs to a packaging printing material. Background technique [0002] At present, it is disclosed that the double-layer composite packaging materials used are mostly plastic film and plastic film composite, plastic film and aluminum film composite, and plastic film paper or cardboard composite, but in this case, paper or cardboard printing is used. Finally, the printed surface is combined with the plastic film. This product adopts lithographic printing, also known as offset printing, which requires a large investment in equipment and strict requirements on paper quality, resulting in high product costs. It is limited to single-sheet printing and the printing area is limited. The printing effect is also not ideal.
