摘要： A packaging material is provided including a substrate, and an oxygen transmission inhibiting layer that is carried by the substrate. The oxygen transmission inhibiting layer is formed of a composite material including a linear polysaccharide medium within which one or more additives are dispersed. The composite material is capable of forming a substantially continuous film to provide a barrier to transmission of oxygen gas. The oxygen transmission inhibiting layer is configured within the packaging material at a thickness that is efficacious in inhibiting the transmission of oxygen gas therethrough. A packaging device has two or more component parts, at least one of which is formed of the packaging material. The component parts of the packaging device are shaped and/or configured to be assembled to define an interior region within which goods are to be contained.

摘要： A rotating pulp suction and robot transfer molding machine includes: a frame and a pulp container located at an inner bottom of the frame. A pulp container drive mechanism is connected to the pulp container and drives the pulp container to move up and down. A pulp suction vacuum pipeline is arranged horizontally and two ends thereof are rotatably connected on the frame. A pulp suction mold is fixed on the middle of the pulp suction vacuum pipeline and connected thereto by a vacuumizing connecting structure. An extrusion mechanism downwardly engages with the pulp suction mold and extrudes pulp to prepare a wet blank of pulp product. A robot is mounted with a transfer mold and used to transfer the wet blank to outside of the frame. A high-low pressure sprinkler pipe is horizontally slidably connected with the frame and transversely arranged above the pulp suction vacuum pipeline.

摘要： A pulp paper formed flange cover is provided. The pulp paper flange cover is adapted for protecting hydraulic motor/pump housing ports and openings, and surrounding surfaces. The flange cover may be infused with corrosion-preventive chemicals to protect the housing from corrosion. Additionally, the flange cover protects the housing surface from damage while preventing infiltration of the openings of the housing by contaminants.

摘要： The present invention relates to a plant molding process and device which the process includes: forming a pulp enveloping layer of molding products by dewatering paper serous fluid; forming a plant pulp layer of molding products by dewatering plant serous fluid; laminating the pulp enveloping layer and the plant pulp layer and processing non-fibrous material of the plant pulp layer to make it migrate toward the pulp envelope layer thereby combining them together. The plant molding device includes a vessel for containing slurry, a mold unit connected to the vessel by a transmission line and realized product transmission by a guiding device. This process can use different components of plants to help shape and improve strength, and to achieve 99% plant material utilization rate, energy conservation and environmental protection. The device is of intelligent operation, low manual intervention, low cost, high production efficiency and product yield.

摘要： A dredging slurry system with a pulp tank is introduced, which is applied for a wet paper pulp molding apparatus. The system comprises the pulp tank, a dredging slurry mold seat, an activating unit, a slurry-physical-feature detection unit and at least one inflow unit and a control unit. The slurry-physical-feature detection unit is used to detect at least one physical feature from a slurry within the pulp tank, during a plurality of different stages, thereby relatively outputting a physical feature data. The control unit is used to control the at least one inflow unit to a manner whether to pour a newly-added slurry into the pulp tank or not, depending upon the physical feature data.
