Freeze-dried food shrinkage rate is far lower than other dried food, fresh food to maintain shape. Freeze-dried food without surface hardening, moon cake carton packaging, and in the rehydration water can quickly penetrate into the interior freeze-dried food, it has excellent rehydration properties. Freeze-dried food during processing to avoid common food processing heat-sensitive components are damaged, easily oxidized components are oxidized phenomenon. Triangle cylindrical carton tray and seal type categories, and a variety of boxes to choose from. Compared with the general corrugated boxes, corrugated triangular prism in the standard state, the compressive strength can be increased by 20% -30%, humidity and the state increased by 40% -60%; convex drum casing does not occur, fruit cartons in the wet state is particularly evident; from the structural point of view, Zhoukou carton, the corner part of the more robust, so the drop shock and vibration, the contents breakage rate is very low; when the load is applied, carton deformation stable, easy to cause the stack to collapse ; tray-type triangular prism of corrugated boxes retail display is good.
