Dongguan box custom designed to determine the final effect of the product is what Dongguan box customized product design decisions is what the ultimate effect of Dongguan box customized product design decisions ultimate effect: on the carton is particularly important in terms of design, it would be difficult to meet customer requirements may occur returned, causing heavy losses to the enterprise. Calculate the lowermost carton can withstand the maximum stacking load Ps namely Ps = (Nmax-1) · G, which, Nmax is the maximum stacking layers of packaging box, G for the contents and container weight. Select the appropriate safety factor K. Of course, for safety reasons, the safety factor is usually taken 3 or more. However, the safety factor has made too large, the indices of raw materials is relatively high, the price of paper will be significantly increased, resulting in increased costs and unfavorable market development. Again, if the safety factor chosen is too large, there will be mass excess coefficient is too small mouse gift packing box, and other quality problems caused by the collapse box. Therefore, according to the actual requirements of customers, select the appropriate safety factor. Calculated to be achieved according to the maximum compressive strength value of the safety factor P, according to Kelicutt formula, select the appropriate paper combinations. What is it boxed printing ink additives ink additives is used to adjust the ink industry to adapt to different printing conditions supporting material. Color box packaging and printing ink additives use of many different types of commonly used agents have withdrawn sticky, sprinkle light, drying agents, anti-desiccant, thinner, rubbing agents, varnish, anti-offset agent, varnish and so on, a brief introduction and its use of the following common ink additives. First, sprinkle withdraw sticky sticky agent has little adhesive agent, generally used for lithography and sudden printing ink to reduce its viscosity. In offset printing, due to changes in the performance of paper and printing conditions, such as oil absorption, surface strength is poor, there are positive and negative coating conditions fall phenomenon, when desiccant excessive or printing workshop room temperature is too low, can cause paper galling, printing heap version, paste version of such failure, affecting the quality of printed products. Therefore, when the above phenomenon occurs when the hair dryer packaging box, you can add the right amount of withdrawal sticky agent, you can play weaken and eliminate the role of the above failure. Second, talk about agents withdraw withdrawal pale agents known as diluent, is used in offset printing larger than the aid. Common withdrawal pale agents, there are two: one is the transparent oil-based ink for light; a light resinous withdrawal packaging box factory in Dongguan agent for the resin ink. If it is found too can not restore the original color of the ink in printing, you can add the right amount of light agent, so as to achieve the desired effect.
