In addition, there are also differences in performance between EPS foam boxes and EPP insulation boxes. They all have good thermal insulation properties and can effectively isolate temperature changes and keep the temperature of items stable. However, EPP material has stronger impact resistance and shock-absorbing properties than EPS material, and can effectively protect items from external impacts.

The main reasons why EPS foam boxes are gradually being eliminated are as follows. First of all, EPS materials will produce a large amount of harmful substances during the production and processing process, causing certain pollution to the environment. Secondly, EPS foam boxes are easily damaged during use and cannot be reused, resulting in a waste of resources. In addition, because EPP insulated boxes have better durability and re-usability, they have more advantages in cost and environmental protection, gradually replacing EPS foam boxes.
