[0002] Labels often carry specific information about the corresponding products, and generally need to be attached to the products for users to understand the information about the products. Currently, most product information labels have been replaced by product QR codes. Therefore, you only need to attach a label with a product QR code to the product, and users can scan it with their mobile phones to understand the relevant information about the product. The area of ​​each label of this type of label is relatively small. Currently, most of them are in the form of self-adhesive label paper tape rolls in which several labels are neatly arranged on a release paper tape to form a roll. The composition usually includes a label printed with a QR code or related information, a self-adhesive adhesive adhered to the back of the label, and a release paper tape attached to the self-adhesive adhesive. The release paper tape can be affixed to only one column of labels or multiple columns of labels in parallel. When it is necessary to attach it to the product, the label and the release paper need to be peeled off first, and then the label needs to be attached to the product.
