How to choose the inner support of the electronic product box

1. High-density sponge, when picking inner support for electronic product boxes, the first consideration must be safety. Why EVA was sought after in those years is because EVA has very strong protective performance and excellent cushioning capacity, otherwise Cosmetics packaging mainly based on bottles and cans will not choose EVA as the material so much, and then it is why high-density sponge replaces EVA's internal support function, because the current price of high-density sponge is relatively cheap. I have been disliked before because the appearance of the high-density sponge is really very general, and it can even be said to be a bit ugly, like a sieve that a dog has gnawed through. So in 2018, everyone had relatively sufficient funds and added a little cost. It can be changed to a configuration that is equivalent to the industry’s internal support and top configuration, and the price/performance ratio is not bad. But now because all walks of life have been impacted, on the premise of ensuring functionality, the appearance is the first choice to be discarded, so EVA will naturally Not competitive anymore

2. Cardboard inner support. I did not expect that only two or three years have passed. The trend of electronic product box inner support has returned to paper inner support. Paper inner support is really the biggest winner among various materials, because paper inner support The production process is relatively simple, so the price is relatively cheap. However, if the paper inner support is passed through a different slotted beer, a relatively stable structure can be formed. Compared with the high-density sponge mentioned above, the protection of the paper inner support The performance mainly depends on the paper thickness of the inner support, but remember 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. Will make a better choice.
