Description
Technical Field
The patent of the utility model relates to a straw fiber material and packaging material field, concretely relates to degradable straw fiber packing boxboard.
Background
With the rapid development of the logistics industry in China in recent years, the demand on packing boxes for transporting goods is increasing, at present, most packing boxes are made of corrugated paper and cannot carry heavy goods, the waterproof and anticorrosive performances are very poor, and packing boxes made of special goods such as agricultural products, precision instruments and the like are mainly made of solid wood, metal or plastic, most of the packing boxes are abandoned after being used, so that certain resource shortage and solid pollution are caused. On the other hand, the yield of crop residues and straws in China is huge, the raw materials of fiberboards made of the straws are wide in source and low in cost, and if the straw fiberboards are used as the base materials to make the packing box boards, the whole weight of the packing box can be reduced, and the logistics cost is reduced. The straw fiber belongs to a natural degradable material, and the packing box made of the straw fiber has no solid pollution problem even if the straw fiber cannot be recycled after being discarded. The invention has the advantages that the waterproof and heat-insulating properties of the straw fiber board are innovated, the prepared degradable straw fiber packing case board can be applied to the manufacture of packing cases of agricultural products, refrigerated goods and the like, and the degradable straw fiber packing case board has good fresh-keeping effect in food transportation. Compared with other non-degradable plastic or foam plates, the packing box plate has the advantages of stronger functionality, good performance and easy degradation, and the problem of solid pollution does not need to be worried about after use.
