At present, most of the back surfaces of the base papers of PET release materials in the market are not printed with patterns, and when the glue-coated composite surface material is formed into products, the glue-coated composite surface material is plagued to company brands and meanwhile cannot form brands.
When the pattern is printed on the back surface of the common single-layer PET release type base paper and the composite surface material is glued, after the pattern is printed on the back surface of the base paper and the surface material is contacted (particularly, the surface material is semi-hard PVC) ink is easily transferred to the surface material layer, and the appearance and the use of the material are affected, so that the material applied by a commercially available engraving machine (household or commercial) at present has a substrate structure formed by compositing double-layer PET, the ink is between the two layers of PET during compositing, and the ink cannot be transferred to the surface material. However, the shrinkage ratio of the two PET layers is different, and the material is curled and other defects occur during processing. The existing commercial materials have the defects of high price, complex process, poor temperature resistance, easy generation of inertial curling after long-time shelf placement and the like when being sold in a roll shape.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model aims to provide the laser bottom printing release base material, and the laser printing layer is arranged on the back surface of the single-layer base material layer, so that the laser layer cannot be transferred to the surface of the rubberizing surface material, the same effect as that of the double-composite-layer PET base material is achieved, the product stability is improved, the material loss is reduced, and the cost is reduced.
The first object of the utility model is achieved by the following technical scheme:
a laser underprinting release base material comprises a release silicon oil layer, a base material layer and a laser printing layer which are sequentially arranged; wherein the substrate layer has a single-layer structure.
Further, the thickness of the base material is 25um-300um.
Further, the total thickness of the substrate is 50um-180um.
Further, the release silicon oil layer is one of an addition type release silicon oil layer, a condensation type release silicon oil layer, an ultraviolet light curing type organic release silicon oil layer and an electron beam curing type organic release silicon oil layer.
Further, the substrate layer is one of a matte transparent substrate layer and a white substrate layer.
Further, the substrate layer is one of a polycarbonate substrate layer, a polyethylene naphthalate substrate layer, a polyethylene terephthalate substrate layer, an oxalic acid modified-polyethylene terephthalate substrate layer, a polylactic acid substrate layer, a cellulose substrate layer and a polypropylene substrate layer.
Further, the substrate layer is a white PET layer.
Further, the thickness of the substrate layer is 50um-180um.
Further, the laser printing layer is provided with laser patterns.
Further, the laser pattern comprises one or more of pattern, color, company name and design icon.
Compared with the prior art, the utility model has the beneficial effects that:
the substrate comprises a release silicon oil layer, a substrate layer and a laser printing layer which are sequentially arranged; wherein the substrate layer has a single-layer structure. Because the thickness of the laser printing layer is lower, and the substrate layer is of a single-layer structure, the laser printing layer cannot be transferred to the surface of the rubberized surface material, namely the printing ink of the laser printing layer cannot be transferred to the substrate layer. The appearance and the application of the surface material are not affected while the information printing is carried out, so that the same technical effect as that of the double-composite-layer PET substrate ink coating is achieved. And the substrate layer is of a single-layer structure, so that the problem of poor material curling and the like caused by different shrinkage ratios of two layers of PET (polyethylene terephthalate) is avoided during processing, the stability of the product is improved, the material loss is reduced, and the production cost is reduced.
