Abstract

The invention provides a BOPP detachable and undetachable label and a preparation process thereof. The label consists of a detachable area and an undetachable area. The detachable area includes thermal sensitive paper, a polyacrylic acid glue layer, a barrier varnish layer, BOPP, a hot melt pressure sensitive adhesive layer, a solvent-free water-based silicone oil layer, and glassine bottom paperfrom top to bottom. The undetachable area includes the thermal sensitive paper, the BOPP, a hot melt pressure sensitive adhesive layer, a solvent-free water-based silicone oil layer, and the glassinebottom paper from top to bottom. During preparation, the glassine paper is coated with silicone oil and a hot melt pressure sensitive adhesive, composited with the BOPP, coated with barrier varnish and polyacrylic acid glue with high viscosity, and composited with the thermal sensitive paper. The label is simple in structure, meets the requirements of express logistics, and avoids headless parts during transportation. Furthermore, the preparation method is simple and the cost is low.

Description

technical field [0001] The invention relates to a label and a preparation process thereof, in particular to a BOPP detachable and non-detachable label and a preparation process thereof. Background technique [0002] Due to the relatively low surface energy and weak polarity of BOPP, the difficulty of label production is increased. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a BOPP detachable and non-detachable label with simple structure and low preparation cost and its preparation process. [0004] To achieve the above object, the technical scheme of the present invention is as follows: [0005] A BOPP detachable and non-detachable label. The label is composed of a detachable area and a non-detachable area. The detachable area includes thermal paper, polyacrylic glue layer, barrier varnish layer, BOPP, hot-melt pressure Sensitive adhesive layer, solvent-free water-based silicone oil layer and glassine back...
