上光、覆膜是两种不同的工艺。上光是对印刷品表面涂布上光油，罩上一层亮膜，和平工艺比较简单，成本也低，但效果不及覆膜好。覆膜是用热压加工方法在印刷品表面粘贴一层聚乙烯或聚丙烯薄膜，形成一种纸塑合层的印刷品，具有十分良好的光亮度和耐磨性能。覆膜板采用高温压制复合而成，它的致密性和强度都很高，韧性也很好。与木材相比，其静态弯曲强度是木材的两倍以上。覆膜板幅宽，拼接部位少，与铝钢模板相比，支撑和拆卸速度会快很多。同时，其建设成本会相对较低，可以有效缩短工期。另外，这种材料的重量更轻，剪钉性能会更好，所以使用起来非常方便，速度也会更快。覆膜板耐水性强，在制造过程中，每层都使用酚醛树脂，然后热压，因此面板使用后不易变形。同时，其导热系数远低于钢膜，因此无论是夏季还是冬季都可以正常施工。
Upper light and film coating are two different processes.The light is to paint the surface of the printing product with light oil, covering a bright film, the peace process is relatively simple, the cost is also low, but the effect is not as good as the film.Cover film is a layer of polyethylene or polypropylene film pasted on the surface of the printing product, forming a paper-plastic layer of printed product, with very good brightness and wear resistance.The film cover plate is made of high temperature suppression composite, it is very high density and strength, the toughness is also very good.Its static bending strength is more than twice that of wood.The coating plate is wide and has less splicing parts, and the support and disassembly speed will be much faster than the aluminum steel formwork.At the same time, its construction cost will be relatively low, which can effectively shorten the construction period.In addition, the material is lighter and cuts the nails better, so it is very easy to use and is faster.The coated plate has strong water resistance. During the manufacturing process, phenolic resin is used in each layer, and then hot pressure, so the panel is not easy to deformation after use.At the same time, its thermal conductivity is much lower than the steel film, so whether in summer or winter can be normal construction.
