1. Packing Inlay In fact, many inner trays are currently divided into three materials occupying the supply chain of the mobile phone packaging box. One is the more common blister, which is used by Apple and Samsung. and the second is that everyone usually EVA is also seen in other packaging box customization,like Custom packing box,shipping box, but EVA is more likely to appear in some cosmetic packaging, or in some very high-end electronic product gift boxes, so this material is rarely seen in the general mobile phone market. As we recommend,most of the used phone wholesaler,they are willing to use EVA to custom there own mobile phone package box.The third is the material that has been eliminated, paper inner support, paper inner support is generally used in the still or corrugated box, because the thickness of the paper inner support is very thick, much thicker than single copper paper, so if you use In the current box of electronic product packaging box manufacturers, it will appear out of place, so the wind direction of inner support has always been dominated by blister.Materials Before 2012, when Nokia occupied the mobile phone market share, the corrugated box was basically the standard configuration of the mobile phone packaging box. Because of the double-layered nature of the corrugated box, its shock-absorbing ability was relatively high, and it was pasted with a layer of rich colors. In fact, it has reached people's consumption aesthetic standards. However, due to the innovation of products, Android and IOS systems quickly occupied the market. Their market changes also brought about obvious changes in packaging styles. The corrugated boxes of the previous mobile phone packaging box factories were directly eliminated. It is the tacit understanding between each other. The unification has been replaced by the cardboard + paper-laminated model. The operation of changing the dynasty was completed almost in 2011, which is really shocking.
