Technological innovation of functional corrugated board and carton (II)
normal> clip molding
normal>
normal> the plastic film soaked in antibacterial agent and preservative is made in corrugated board, and then CTM preservative is coated on the inner surface of corrugated paper, which is composed of plant hormone abscisic acid and its derivatives, oxyphenone and its derivatives (such as sabitol) and terpene ether. This kind of corrugated board can prevent moisture evaporation, maintain the freshness of goods in the box, and adjust and control the temperature
normal can withstand the influence of high and low temperature cycle. Mal>
normal> composite
normal>
normal> the aluminized fresh-keeping film is coated on the inner surface of corrugated board. This composite film has the function of absorbing ethylene gas. The aluminized film can not only prevent water evaporation, but also reflect radiant heat, prevent the temperature rise in the box, and play a fresh-keeping role

normal> combines foamed plastic with corrugated. Compared with ordinary and plastic corrugated board, it has 2. Better fresh-keeping effect of sample installation. (see the table) the moisture permeability is 1/20 of that of ordinary corrugated board, which is not easy to cause fruits and vegetables to wilt due to water evaporation
normal>
normal> due to the low number of heat conduction systems and good heat resistance effect, there will be no sharp temperature fluctuations in the box. Because the air permeability can stop showing the experimental data in real time, recording and printing are low. Engineering plastics and general plastics are most used in cars, which can adjust the storage atmosphere. The carton made of the above three kinds of corrugated cardboard was used to evaluate the fresh-keeping effect of cauliflower. The results showed that the oxygen content in the foam type fresh-keeping corrugated cardboard box gradually decreased, the CO2 concentration increased, and the respiration and growth of cauliflower were inhibited; The cauliflower packed with plastic paperboard bloomed less due to lack of oxygen, but there were diseases and pests, with a strong odor; The atmosphere in ordinary cartons is almost the same as that in the atmosphere, and vegetables turn yellow and deteriorate
