Provided are a manufacturing and quality testing method and a manufacturing device for a printed product capable of resisting abnormal environmental changes and operating in all weather and suitable for hygiene management operations, as well as the printed product, which relate to the technical field of printing. The manufacturing and quality testing method for the printed product includes the following steps: selecting a material for producing a content component of the product, the material having a structure that exhibits bi-characteristics; preparing a polyurethane adhesive; forming waterproof and weather-resistant images on a sheet material of the content component of the product by an appropriate printing method; performing connecting between the content component of the weather-resistant product and a cover; and sampling and testing are performed to assure quality during the process of manufacturing the product capable of operating in all weather and capable of being disinfected and washed. The printed product can resist extreme temperatures and operate in all weather under abnormal environments, and is cost-effective and durable.

A water-dispersible composite structure, which comprises one or more layers, and a method of producing the same. At least a part of the layers is formed by a fibrous web or sheet containing 50-90 parts by weight of wood fibers and 10-90 parts by weight of annual or perennial plant fibers and/or 10-50 parts by weight of synthetic short-cut fibers, and 0.1-20% by weight of a binder, calculated from the weight of the fibers, and at least a part of the binder being a water-soluble polymer and another part a water dispersible binder, and the fibrous sheet or web being produced by wet forming. By means of the invention, the fibers of the composite structure can be recovered and recycled by equipment conventionally used in the paper and paperboard industry.
