Environment friendly release paper coated with silicon partially and preparation method thereof

Abstract

The invention belongs to the technical field of self-adhesive label materials, in particular to an environment friendly release paper coated with silicon partially and a preparation method thereof. The release paper sequentially comprises backing paper, a silicon oil layer, a first gum layer, barrier paper, a partial location dyeing silicon oil layer, a second gum layer and a heat sensitive paper plane materiel from bottom to top, wherein the part which is arranged between the barrier paper and the second gum layer and not coated with a dyeing silicon oil layer is a release surface without silicon oil, and the size and the color of the dyeing silicon oil layer are confirmed according to the use requirement; the silicon oil layer is obtained by coating solvent-free silicon oil layer solution, and the dyeing silicon oil layer is obtained by coating dyeing solvent-free silicon oil solution. The release paper which can be used as a self-adhesive label material brings great convenience to on-line working staffs on the aspects of final application, on-line quality tracking and process regulating in the manufacturing process, greatly improves the working efficiency, lowers the product testing error frequency and also satisfies special requirements of clients.

Description

technical field [0001] The invention belongs to the technical field of self-adhesive label materials, and in particular relates to a release paper for two-layer or multi-layer label materials and a preparation method thereof. Background technique [0002] Self-adhesive labels are loved by people because of their convenient use and good sticking effect. At present, there are many kinds of self-adhesive materials sold on the market, with a wide range of applications, and the overall structure is the same. [0003] With the continuous development of society, some customers have higher and higher requirements for the types and labels of labels. When the same product information is used in multiple production processes, the structure of such labels is generally two or more layers of labels. The requirements for the material are also very strict, and the quality of the release force determines the quality of the label; the general method of silicon coating is full coating, and the...

Problems solved by technology

Detection methods for labels and release paper: one is to separate the label from the substrate to detect the release force of the label, and the other is to test the uniformity of silicon coating with a water pen. This quality inspection method is very inefficient , and the probability of error is high, the label after inspection cannot be used again, causing serious waste, thereby increasing the production cost
