The plastic film impregnated with antibacterial agents and preservatives is made in corrugated paperboard, and then the inner surface of the corrugated paper is coated with CTM preservative, the components of which are phytohormone and its derivatives, tropolone and its Derivatives are beneficial to substances (such as cerberol) and terpene ethers. This type of corrugated board prevents moisture from evaporating, maintains the freshness of the merchandise inside the box, and also regulates and controls the temperature.

Normal> Laminating aluminum-coated cling film on the inner surface of corrugated paperboard. This composite film has the function of absorbing ethylene gas. The aluminized film can not only prevent water from evaporating but also reflect radiant heat and prevent the temperature inside the box from rising. Preservation effect.

Normal > Combines foam and corrugated. Compared with ordinary type, sandwiched corrugated board, it has better preservation effect. (See the table) The moisture permeability is 1/20 of that of ordinary corrugated cardboard . It is not easy to cause fruits and vegetables to shrink due to moisture evaporation.

Normal > Due to the low number of heat-conducting systems, the heat-resistance effect is good, and no sharp temperature fluctuations occur inside the box. Due to the low air permeability, it can adjust the storage atmosphere. The use of the above three kinds of corrugated board to make cardboard boxes, and evaluate the preservation effect of cauliflower. As a result, the oxygen content in the foam type fresh-keeping corrugated board boxes gradually decreased, the concentration of CO2 increased, and the respiration and growth of the cauliflower were suppressed; the sandwiched cardboard was used for packaging. Although cauliflower blooms due to lack of oxygen, there are pests and diseases, and there are strong offensive odors; while the atmosphere in the ordinary carton is almost the same as that in the atmosphere, and the seasoning of the carton turns yellow.
