Molded pulp tray with composite structure and production method thereof

Abstract

The invention relates to the technical field of logistical conveying tools and discloses a molded pulp tray with a composite structure. According to the arrangement, a molded pulp body structure, a honeycomb cardboard and a corrugated board are combined and packaged; the honeycomb cardboard is light, cheap, high-strength and the like, and a honeycomb structure is large in bearing ratio, so that the molded pulp tray is high in strength, recycled or thoroughly degraded and simple in structure. The invention further provides a production method of the molded pulp. In the simple production method, the molded pulp body, the honeycomb cardboard and the corrugated boards are packaged to achieve the molded pulp tray high in bearing strength. The production method is simple in method, easy to operate, high in production efficiency and cost saving.

Description

Technical field [0001] The invention relates to the technical field of logistics conveying tools, in particular to a pulp molded tray with a composite structure and a manufacturing method. Background technique [0002] Pulp molding is a three-dimensional papermaking technology. It is a paper product with a certain shape formed by a special mold on a molding machine. The pulp molding structure is an open three-dimensional space and has a uniform thin-walled structure. Large-scale pulp molded structures have poor strength and rigidity and are easily deformed. Therefore, the current pulp molding on the market is mainly used as the inner packaging of the product, and it is rarely used as the logistics pallet that bears heavy loads. Therefore, in the logistics industry, wood pallets or plastic pallets are commonly used. The use of wooden pallets requires cutting down a lot of trees, which is easy to destroy the natural ecology, while the pallets of plastic products are obtained throu...

Large pulp molded structures have poor strength and rigidity and are easily deformed

Therefore, pulp molding in the market is mainly used as the inner lining packaging of products, and it is rarely used as a heavy-duty logistics pallet. Therefore, in the logistics industry, wooden pallets or plastic product pallets are more commonly used. The use of wooden pallets needs to cut down a lot of trees, which is easy to damage the natural ecology, while the pallets of plastic products are obtained through petroleum refining. This kind of plastic products is not easy to degrade after use, and a large number of discarded plastics are easy to cause damage to the environment. Therefore, combined with the current Due to the current situation of pallet use in the logistics industry and the shortcomings of existing pulp molding, the inventor has invented a pulp molding pallet with a composite structure and a manufacturing method after repeated tests and demonstrations.
