Problems solved by technology

[0006] To sum up, the existing sealing labels that can be repeatedly peeled and pasted mainly have the following problems: 1) The commonly used film substrate has too high oxygen permeability and moisture permeability, resulting in low barrier performance and poor sealing effect of the label; 2) Some labels There is no defense barrier for antibacterial and disinfection, which causes the label to be easily eroded by microorganisms after being opened many times, and the hygiene and safety are not up to standard; 3) The adhesive force of the existing label is reduced or even lost after repeated tearing, opening and pasting, resulting in sealing failure; 4 ) Due to the insufficient surface tension of the adhesive surface of the surface material, when the sealed label is pasted on a layered bag and / or container with a high surface tension, it is easy to cause the adhesive to be torn and pasted many times to transfer and remain on the object to be pasted

Abstract

The invention discloses an antimicrobial sealing label capable of being torn and stuck for a plurality of times and a preparation method and application of the antimicrobial sealing label. The antimicrobial sealing label capable of being torn and stuck for the plurality of times comprises a thin film base material which has oxygen permeability lower than 5.0mL / (m<2> 24h 0.1MPa) and moisture permeability lower than 5g / (m<2> 24h) and contains a PVDC (Polyvinyl Dichloride) coating material, an antimicrobial pressure-sensitive adhesive composition with viscous force greater than 44mN / m and adhesive force greater than 2N / inch, and a release type substrate which has release force smaller than 25g / inch and contains a silicone oil coating. After an antimicrobial sealing label material is cut into a label, the label is used for sealing a product package and has an antibiotic inhibition effect; the sanitation and safety can be effectively ensured, the number of times of tearing and sticking the sealing label and the sealing effect are improved, and a phenomenon that the sealing label is torn from and stuck on an stuck object and an adhesive is remained is avoided.

Description

technical field [0001] The invention belongs to the technical field of labels and materials thereof, and in particular relates to an antimicrobial sealing label material capable of being torn and pasted multiple times, a label and a preparation method and application thereof. Background technique [0002] Pressure-sensitive adhesive labels, as the body of information, can be seen everywhere in daily life. Its basic function is to carry the information of the posted product and its manufacturer, embellish and beautify the posted product.
