High-viscosity box-sealing tape

Abstract

The invention discloses a high-viscosity box-sealing tape. The box-sealing tape comprises a substrate layer and a glue layer, wherein the glue layer is pasted on the surface of the substrate layer; the material of the substrate layer is a glass fiber cloth; and the material of the glue layer is an emulsion formed by mixing an acrylic acid emulsion and a vinyl acetate based emulsion, the acrylic acid emulsion accounts for 30-40%, and the vinyl acetate based emulsion accounts for 60-70%. In the above manner, the viscous force of the box-sealing tape can be greatly increased. The middle of the glue layer is provided with a strip-shaped groove arranged in the length direction thereof, and paraffin mixed with staining agent is filled in the strip-shaped groove; and the high-viscosity box-sealing tape is heated by a blower before being used. According to the invention, the forgery prevention mode of the strip-shaped groove is used, thereby furthest ensuring that a consumer can know whether the box-sealing tape has been torn by others in advance at the first time.

Description

technical field [0001] The invention relates to a packaging material, in particular to a high-viscosity sealing tape. Background technique [0002] At this stage, adhesive tape is widely used in various fields by virtue of its unique convenience and stickiness, especially in the packaging field, where its use frequency is particularly frequent, but now the ordinary sealing tape is not viscous enough, resulting in the sealing effect They are all relatively poor, and with the development of science and technology, ordinary sealing tapes can no longer keep up with people's needs, so a high-viscosity sealing tape has a good market prospect. [0003] At the same time, the traditional sealing tape has almost no anti-counterfeiting performance. When it is opened and then pasted again, there is almost no trace of being opened on the surface, thus providing an opportunity for unscrupulous merchants. Therefore, finding a kind of possessing good anti-counterfeiting performance, avoids...
