Problems solved by technology

However, the sealing tape made by this process has the following defects: one is that the conventional adhesive has poor water resistance, and once it is damp, the glue is prone to foaming and loses its bonding performance; The process of cutting into strips after gluing leads to shear stress at the edge of the tape, and the tape is very prone to flanging at the edge during use

Abstract

The invention discloses a preparation method of a bubble-resistant box sealing tape. The preparation method comprises the following operation steps: (1) cutting a biaxially-oriented polypropylene (BOPP) thin film so as to enable the thin film to have a width of 48-72mm; then, putting the cut BOPP thin film into a mixed solution, heating the mixed solution up to 40-50 DEG C, and carrying out heat insulation treatment for 5-7min; (2) coating the BOPP thin film treated in the step (1) with an adhesive, then naturally drying, and winding to obtain a finished product. The bubble-resistant box sealing tape prepared by the method provided by the invention is high in adhesive property, and all performance indexes of the bubble-resistant box sealing tape meet the JB/T 10456-2004 industry requirements; furthermore, the bubble-resistant box sealing tape is excellent in bubble resistance, thus not having the phenomenon of blistering and the like after being wetted.

Description

technical field [0001] The invention belongs to the field of preparation of sealing tapes, in particular to a method for preparing blister-resistant sealing tapes. Background technique [0002] Sealing tape is also called BOPP tape, packaging tape, etc. It is based on BOPP biaxially oriented polypropylene film, and is evenly coated with pressure-sensitive adhesive emulsion after heating to form a glue layer ranging from 8 μm to 28 μm. It is an indispensable product in the life of light industry enterprises, companies and individuals. The common preparation method of sealing tape is as follows: after the BOPP original film is treated with high-voltage corona, one side of the surface is roughened, and then the glue is applied on it to form a tape master roll, and then cut into different specifications by a slitting machine. The small roll is the tape we use every day. The pressure-sensitive adhesive emulsion is mainly composed of butyl ester. However, the sealing tape made b...
