[0002] Foam boxes are box-type packaging containers made of foam plastics. Boxes made of foam are often used to pack fragile items or items that need to be kept cold. Foam boxes are the most commonly used packaging tools for transporting seafood. Frozen seafood, or fresh seafood and ice cubes are placed in the packaging box, and then sealed for transportation, which can effectively reduce the heat exchange inside and outside the foam packaging box, ensure the low temperature environment in the foam packaging box, and achieve the effect of freshness; but The existing foam packaging box has a low reuse rate. After repeated use, its overall shape is prone to deformation or breakage, making it difficult to use it multiple times, thereby increasing the number of foam boxes used, which is very harmful to environmental protection. friendly

Abstract

The invention belongs to the field of foam packaging boxes, particularly relates to a processing method of an environment-friendly foam packaging box, and aims to solve the problems that an existing foam packaging box is low in reuse rate, the overall shape of the existing foam packaging box is prone to deformation or breakage after the foam packaging box is transferred and used for multiple times, and the existing foam packaging box is difficult to use for multiple times, so that the use number of foam boxes is increased, and the environment protection is not friendly. The following scheme is provided: the method comprises the following steps: S1, sequentially weighing the following raw materials in parts by weight: 50-80 parts of polystyrene particles, 30-50 parts of modified starch, 20-40 parts of a strong solvent, 10-20 parts of a flame retardant, 20-40 parts of absolute ethyl alcohol, 10-30 parts of methyl tert-butyl ether and 10-20 parts of azodicarbonamide. The foam packaging box is high in reuse rate, the overall shape of the foam packaging box is not prone to deformation or breakage, the foam packaging box can be used repeatedly, and meanwhile the foam packaging box is high in degradability and quite friendly to environment protection.
