当将淋膜纸作为离型纸或诱虫纸等用途时,一般必须使用具有特定颜色的有色淋膜纸。目前有色淋膜纸的制造步骤大致包括:(1)选用有色原纸:依据淋膜纸的功能选用适当厚度、规格、材质及颜色的有色原纸,一般是选用韧性强且表面较为粗糙的道林纸类来作为原纸,藉以增强淋膜的渗入及附着力;(2)淋膜:以聚乙烯或聚丙烯进行淋膜,于原纸的一侧或两侧的表面形成一淋膜层;(3)液压及冷却定型:最后经过液压轧平及冷却定型,即可制造出具有颜色的淋膜纸。现有的淋膜纸构造以染色的有色原纸构成淋膜纸的色彩层,不仅染色的有色原纸存在有颜色及光泽不均匀的问题,导致淋膜纸的质量不稳定,并且无法在淋
When using a lamination paper as a release paper or an insect-attracting paper, etc., it is generally necessary to use colored lamination paper having a specific color. At present, the manufacturing steps of the colored lamination paper generally include: (1) The selection of colored base paper: According to the function of the lamination paper, the appropriate thickness, size, material and color of the colored base paper are generally selected. (2) Lin Mo: polyethylene or polypropylene lamination, the base paper on one or both sides of the surface to form a coating layer; (3) Hydraulic and cooling stereotypes: Finally, after hydraulic flattening and cooling stereotypes, you can create a color coated paper. The prior art lamination paper structure uses colored dyed base paper to form a color layer of lamination paper. Not only colored dyed base paper has problems of uneven color and luster, resulting in unstable quality of lamination paper,
