Fresh vegetables are prone to decay during transport, and now it is well protected that the Polyolefin Shrink Film product packaging is so intact. The respiration intensity of broccoli is high, and the post-harvest physiological metabolism activity is very strong. In a short time, it will lose water and turn yellow, which will affect the commodity value of the vegetable itself. Therefore, vegetables must be pre-cooled in time to remove field heat quickly, reduce the temperature and respiration intensity of broccoli, so as to slow down the metabolism of vegetables and extend the shelf life.
POF Shrink Film is widely used in daily necessities, food and beverage, and household chemicals. The application of heat shrinkable film packaging can greatly reduce the material and labor costs of box packaging and has important economic significance.
