The plastic turnover box is the most characteristic type of plastic packaging box. It has the characteristics of small size, lightweight, beautiful and durable, easy cleaning, corrosion resistance, easy molding and processing, convenient use and management, safety and hygiene, etc. It is widely used for beer. soda, fresh fruits, vegetables, milk, eggs, aquatic products, etc.

China Corrugated Plastic Bin Manufacturers introduced that most of the materials used in plastic crates are PP and HDPE. HDPE turnover box has better low-temperature resistance; PP turnover box has better compressive performance and is more suitable for food that needs to be stored for a long time. Because the turnover box is exposed to the sun, rain, and the external environment, it is easy to age and brittle. During manufacture, the raw materials should be selected and appropriate additives should be selected. Generally, resins with a wide molecular mass distribution are used, or HDPE and LDPE are mixed. It needs to be modified by adding antioxidants, pigments, ultraviolet absorbers, etc. to improve the service life of plastic turnover boxes.

At present, EPS foamed plastic turnover boxes are widely used as low-temperature fresh-keeping packaging for fresh fruits and vegetables because of their advantages such as heat insulation, shock-proof buffering, etc.
