Packaging box and single-sheet packaging box prefabricating material and forming method and system thereof

Abstract

The invention discloses a packaging box, a single-sheet packaging box prefabricating material and a forming method and system thereof. The forming method of the single-sheet packaging box prefabricating material comprises the following steps that S10, patterns are printed on packaging paper, indenting is carried out, the packaging paper and an aluminum plastic laminating film are compounded, and arolled packaging material is obtained; and S20, paper of the rolled packaging material is discharged, cutting is carried out, and a single-sheet packaging material is obtained; S30, the outer side ofthe first longitudinal side of the single-sheet packaging material is thinned, the thinned first side is turned outwards to be in lap joint with the inner side of the longitudinal second side of thesingle-sheet packaging material, steam heat sealing connection is adopted, and a barrel-shaped single-sheet packaging material is formed. According to the packaging box, the single-sheet packaging boxprefabricating material and the forming method and system thereof, the packaging paper is printed and indented, and then combining, cutting, edge cutting and steam heat sealing are carried out; on one hand, the problem that printed content is likely to be separated is avoided; and on the other hand, the yield of the single-sheet packaging box is increased, and the problem of packaging box leakageis relieved.

Description

technical field [0001] The invention relates to the field of liquid food packaging, in particular to a prefabricated material for a packaging box and a single-piece packaging box, a forming method and a forming system thereof. Background technique [0002] In the field of liquid food (such as yogurt and juice) in small-volume packaging containers, during the forming process of the single-piece packaging box used by the single-box filling machine, printing is performed on the plastic surface of the composite layer close to the paper, which increases the difficulty of printing. And easy to fall off, affecting product quality. [0003] The term "sterile" means the absence or removal of any microorganisms in a product, package or other specified area; "package" means filled and sealed and is used to denote suitable mechanical properties that do not allow any microorganisms to enter the package, Or strictly speaking, prevent microorganisms and gases and vapors from entering the ...
