Ordering carton customers may often hear from manufacturers such words as "do not recommend large-scale printing" or "can not do large-scale printing". What is the reason?

　　一，纸箱进行大面积印刷会增加生产成本，印刷版跟水墨的用量会增大，这样直接增加了生产成本。其次，废品率会随印刷面积的增大而提高，间接增加了成本。

　　First, large-scale printing of cartons will increase production costs. First, the amount of printing plate and ink will increase, which directly increases production costs. Secondly, the scrap rate will increase with the increase of printing area, indirectly increasing the cost.

　　第二，对纸板有很高的要求，纸板厂的原料水平不一样，造成了纸板可能有透楞、楞硬、楞软等问题，这些都会影响到纸板的印刷。既然如此，选择好一点的纸板不行么？对于这个问题，经过向人员了解得知，纸板受天气湿度影响，涂胶量多或少的影响，都会造成纸板不平整，而且稍微出现不平整，纸板厂是不予退换的。

　　Secondly, there are high requirements for cardboard. The different raw material levels of the cardboard mills have resulted in problems such as corrugated, corrugated, corrugated and soft cardboard, which will affect the printing of cardboard. In that case, can't we choose better cardboard? For this problem, we know from the professional staff that the paperboard is affected by the weather and humidity, and the amount of glue coating is more or less, which will cause the paperboard to be uneven, and slightly uneven, and the paperboard factory will not be replaced.

　　第三，大面积印刷对印刷机有严苛的要求。这么来说，一般的纸箱厂的印刷机械也就20万左右。能做出效果好的大面积额印刷的印刷机差不多要800万左右。

　　Thirdly, large area printing has strict requirements for printing presses. In this way, the average carton factory printing machinery is about 200,000. About 8 million printing presses can produce large-area printing with good results.

　　纸箱可以用于存放或包装一些易损的产品，但是一些穿透能力很强的粮食害虫，能够将包装纸板穿透，不仅损害其中的食品，也会损害食品生产厂家和销售商的声誉，因此纸箱包装可以采用两种防虫方法。

　　Cartons can be used to store or package some vulnerable products, but some insect pests with strong penetration ability can penetrate the packaged cardboard, which not only damages the food, but also damages the reputation of food manufacturers and sellers. Therefore, carton packaging can adopt two methods of insect prevention.

　　1、物理法，通过强度较高的薄膜包装单个食品，使虫子穿不透而防虫。但这种方法必须改变现有的包装生产线，另外也格外增加了薄膜的成本。

　　1. Physical method, packaging individual food with high strength film, so that insects can not penetrate and prevent insects. But this method must change the existing packaging production line, in addition to increasing the cost of film.

　　2、化学法，用涂有化学药剂的纸板包装食品以防虫，其具体做法是在纸板的表面，涂上防虫漆。这种防虫漆并非杀虫剂，而是可以作为食品添加剂的天然精油，其作用不是杀虫，而是驱虫，从外部防止虫子的侵入。这样可以不改变现有的包装生产线，保持较低的成本。其加简单，可以用苯胺印刷机印到纸板表面上，适于小批量生产，废纸板可以回收再生。

　　2. Chemically, food is packaged with cardboard coated with chemicals to prevent insects. The specific method is to coat the surface of cardboard with insect-proof paint. This anti-insect paint is not an insecticide, but a natural essential oil which can be used as food additives. Its function is not to kill insects, but to repel insects from the outside to prevent the invasion of insects. This will not change the existing packaging production line, maintain a lower cost. It is simple and can be printed on the surface of cardboard by aniline printer. It is suitable for small batch production. Waste cardboard can be recycled.
