Problems solved by technology

Generally, to endow the tape with anti-static function, anti-static masterbatch is directly added to the raw material of the tape or an additional conductive adhesive layer is added. However, this method will greatly increase the production cost and greatly reduce the production efficiency, and the anti-static effect Not obvious

Abstract

An anti-static pressure-sensitive adhesive tape comprises a BOPP base material, a corona layer, a decorative layer, an aluminized layer and a pressure-sensitive adhesive layer in sequence from bottomto top. By means of the special layer structure, the pressure-sensitive adhesive tape layer is simple in structure, has a remarkable anti-static effect and is particularly suitable for box sealing andpackaging operation with strict dustproof and anti-static requirements for the workshop environment. The invention further discloses a preparation method of the anti-static pressure-sensitive adhesive tape. By additionally arranging the process steps with low cost, high efficiency and strong controllability, the pressure-sensitive box sealing adhesive tape is endowed with excellent anti-static performance on the basis of not greatly changing the process flow of the existing pressure-sensitive box sealing adhesive tape, and the preparation method is simple and suitable for large-scale industrial production.

Description

technical field [0001] The invention relates to the field of packaging materials, in particular to a pressure-sensitive adhesive tape. Background technique [0002] There are many kinds of adhesive tapes on the market, and the materials and properties of the adhesive tapes are also similar according to different usage requirements. Among them, the sealing tape has attracted the attention of the industry because of its strong practicability, wide application range and large usage. Sealing tape is also known as 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 an adhesive layer ranging from 8 to 28 μm. It is one of the indispensable supplies in light industry enterprises, companies and personal life. Existing sealing tapes generally only have simple adhesive functions and decoration and marking functions, which are increasingly unable to meet people's...
