Manufacturing process for PET cat eye seamless non-positioning aluminized composite paper

Abstract

The invention discloses a manufacturing process for a PET cat eye seamless non-positioning aluminized composite paper. The manufacturing process comprises the following steps of designing a pluralityof cat eye arrangement patterns; copying and transfer-printing the patterns on a nickel plate to a PET mould pressing plate; fixing a covering film to a second traction film such that the printing surface of the covering film faces upwards, and fixing a PET mould pressing plate to the covering film such that the pattern surface faces upwards; printing UV gloss oil on the PET mould pressing plate overlapped with a transparent area; mould-pressing the pattern of the PET mould pressing plate onto a plate roller to form a plate roller without plate seams; coating one side of the film material withcoatings, and drying the film material to form a coating; mould-pressing and transfer-printing the pattern to the coating on one side of the film material through the plate roller; aluminizing the coating on one side of the film material; and gluing one side of the film material, and laminating the film material with the paper to form the composite paper. According to the manufacturing process, the cat eye pattern is transferred to the PET mould pressing plate, the plate roller, the coating on one side of the film material and the composite paper in sequence from the nickel plate, and the seamless plate roller is manufactured by mould pressing, so that the aluminized composite paper with the seamless mould pressing cat eye pattern can be obtained.

Description

technical field [0001] The invention relates to the technical field of cat's eye composite paper, in particular to a production process of PET cat's eye seamless non-positioning aluminized composite paper. Background technique [0002] At present, when making cat-eye composite paper, the sheet-sheet plate is pasted on the plate roller, and the plate roll then molds the film material. However, the sheet-sheet plate will cause molded products to be damaged at the place where the head and tail of the plate roll rotate once. The cat's eye pattern has a very obvious stitching line, which causes the cat's eye pattern to be incomplete, and the quality of the composite paper compounded with the paper is unqualified. For some small patterns, two sets of plate rollers can be used for positioning and repeated molding to make molded products with hidden plate seams. However, for cat’s eye patterns, the outline is usually required to be clear and obvious. At the same time, two embossings...

[0002] At present, when making cat-eye composite paper, the sheet-sheet plate is pasted on the plate roller, and the plate roll then molds the film material. However, the sheet-sheet plate will cause molded products to be damaged at the place where the head and tail of the plate roll rotate once. The cat's eye pattern has an obvious stitching line, which leads to the incomplete cat's eye pattern, resulting in substandard quality of the composite paper combined with the paper

For some small patterns, two sets of plate rollers can be used for positioning and repeated molding to make molded products with hidden plate seams. However, for cat’s eye patterns, the outline is usually required to be clear and obvious. At the same time, two embossings will cause double images of the cat’s eye pattern and affect the cat’s eye. pattern effect
