Large-scale self-adhesive sticker supplier
Large supplier of stickers. The edges of the sticker paper are smooth and undamaged, which is the basis for ensuring the printing quality of the sticker paper. Therefore, you must carefully check whether the slitting edge of the sticker paper material has burrs before printing and whether it is due to storage. Damage occurred due to improper transportation, and the adhesive label material should be rolled down 4-5 times, and the slitting edge should be carefully checked. When cutting the self-adhesive label paper material, if the cutting tool is not adjusted properly or the blade is not sharp enough, cracks will appear on the top or bottom paper of the self-adhesive label paper material, and the fibers pulled out from the crack will be cracked again. The adhesive is stuck. The occurrence of cracks may be continuous or random, and may occur on one side or both sides of the sticker paper material. Therefore, before the sticker paper material is printed on the machine, it is necessary to carefully check its appearance. Check for small cracks in the backing paper and the face paper.
Self-adhesive label paper materials are stuck at the edges or some areas of the bottom paper are leak-coated with silicone oil, which will cause the paper to break during waste processing during printing and cannot be produced normally. Therefore, before printing, take a piece of self-adhesive label paper about 1 meter in length and peel it by hand to see if there are any parts that cannot be peeled off smoothly and uniformly at the edges or other parts. Self-adhesive label paper manufacturers point out that the adhesion of the edges of the top and bottom paper occurs on a slit roll of the entire roll of self-adhesive label paper material, and generally only occurs at the outer layer of 7 to 10 meters, so When encountering the cut edge of the adhesive label paper material, there is adhesion on the edges, do not immediately assert that the entire roll of paper has this problem. Self-adhesive label paper manufacturers point out that the peeling of light-weight tissue paper (such as 60g / m2 and 80g / m2) requires more force than the heavy-weight tissue paper. The lighter the tissue paper, the tighter the feel when peeling . Because of this, sometimes the self-adhesive label paper material selected by the customer in the shape required by the customer cannot be completed at the normal printing speed.
Self-adhesive label paper manufacturers point out that bar code technology labels currently use more bar code varieties, anti-counterfeiting bar codes mainly have two-dimensional bar code and two-dimensional bar code. Sunwind barcode technology can not only promote better and faster application, but also achieve the purpose of not pretending to be impersonal and protecting consumer interests. Self-adhesive label paper manufacturers point out that fragile paper labels use special fragile paper or fragile adhesive materials, which can be printed with trademarks, text clarifications and barcodes, and cannot be lifted completely after being pasted on the packaging. Lift it up and the paper shatters. Letter-type anti-counterfeit polyester film labels, before being lifted, are aluminum foil without words. After being lifted, there are obvious colored handwriting on the label paper and packaging materials.
