EVA insert is often seen in electronic product paper packaging boxes. EVA has very strong protection performance and good buffering ability, which can well protect electronic products from damage.
High-density sponges are also often found in electronic product boxes. Compared with EVA, high-density sponges are softer and have better cushioning properties, but they do not have the same effect as EVA fixed products. At present, the price of high-density sponges is relatively cheap, which is very popular of the electronics packaging box insert options.
Cardboard inner tray, the inner tray trend of electronic product boxes, paper inner tray is really the biggest winner among various materials, because the production process of paper inner tray is more simple, so the price is cheaper. If the same slotted goes down, it can form a relatively stable structure. Compared with the high-density sponge mentioned above, the protective performance of the paper inserts mainly depends on the paper thickness of the paper inserts, but remember, and It's not that the thicker the better, the thicker the cardboard, the more troublesome it will be to fold, so you should make full use of the characteristics of the corners to design, which will make a better choice.
