First of all, we need to understand the characteristics of these two materials, and then choose which material to use in combination with the actual packaging needs of intelligent robots.
EVA is an ethylene-vinyl acetate copolymer that is typically soft and elastic, has good cushioning properties, and is chemically resistant and weather-resistant. EPE is pearl cotton, or polyethylene foam, which is lightweight, cushioning and shock-resistant, as well as good thermal insulation and waterproofing properties. The robot packaging is mainly to prevent it from being damaged during transportation, so it is also important to whether its processed shape can fit the product, because the robot shape is mostly irregular structure, and the lining needs to fit the contour of the fuselage, so as to provide stable support and avoid shaking.

There is another issue, which is cost. The material cost of EVA will be much higher than that of EPE. Of course, EVA material is also more suitable. Therefore, it is difficult for us to directly say which material to use, and we must actually consider it in combination with the final positioning of the product. If you are positioned at the high-end, consider using EVA, and if it is an economy model, then we should consider EPE.
