The technical field to which the invention belongs ... The present invention relates to a biodegradable resin sheet formed by using the biodegradable laminated resin sheet molded article variety biodegradable laminated resin sheet Previous technology: With μ # like a, laminated resin sheets are added on both sides of the base fabric. The resin layer is composed of: water resistance, abrasion resistance, cut-off properties, and fusion properties. Different laminates are widely used in various fields, such as tarpaulins or multi-layer laminates, for industrial use and general goods. For example, in industrial applications, flexible containers or flexible packaging materials used for logistics; in the field of wood construction, it can be used for earthen wood panels, outdoor storage panels, 訑 ° panels, or in the field of daily grocery. It can be used for leisure boards, special packaging materials, and even large vertical banners for indoor and outdoor publicity media.

This laminated resin sheet is composed of two components of a base cloth. And this laminated resin sheet is used for the purpose of strengthening the base cloth system. Laminate the resin layer in order to achieve the integrity of the laminated resin sheet. In the past, the base fabric of the laminated resin sheet was made of cotton wool, hemp fiber, polyester fiber, polyamide fiber, polyolefin fiber, and stone. Long fibers or short fibers of synthetic fibers such as Y natural fibers, or open fibers or flat yarns of polyolefin such as polyethylene = acid fibers, etc. are composed of 1f acrylic cloth or knitted fabrics alone or mixed; or It is made of natural fiber, polyester, or non-woven fabric made of synthetic resin fiber. 1st grade

Description of the invention (2) Therefore, by using this resin, polyurethane; , Fat plate. f fat layer to give raw materials for waste ;: The plate is a structure that is discarded after use, but it is gradually becoming = monthly weight: should be perfectly natural in a recycling-oriented society J: In particular, the problem of system requirements . Packaging materials; flexible materials containers and soft materials for civil construction purposes. Γ2 is composed of processability and applicable films, except for ethylene, and diao when incinerated = the problem of using soft polychloride. Therefore, although the most endocrine disrupting agent is vinyl resin, it is a common situation with non-polychloride incineration treatment such as smoke. / Disadvantages, while still applying this view, there is a need for biodegradability. This biodegradable plastic, or placed in the soil in the second stage, is mixed with fertilizers (composting devices) to enter, and =, or the substance is decomposed into water and carbon dioxide, so as a solution to dioxin: secondary disruption The composition of the problematic material is proposed. As an example of using such a biodegradable plastic, for example, Japanese Unexamined Patent Publication No. 2000: 1 29646 discloses that a biodegradable flat yarn is woven into a soil bag made of a woven fabric. The decomposition rate of this soil bag varies depending on the ambient temperature or temperature, but it usually decomposes within 2 to 3 years. While there

Description of the invention (3) However, it is suitable for the above-mentioned and sometimes' for example, when processing, high-frequency welding , Leakage or needle, and the subject of the present invention is a biodegradable molded article. The sheet is fracture-resistant, and the machineability is quite excellent. Laminated resin sheet == bag! ‘Because it has a tensile strength as a soil bag # θ ^ It is generally considered to be used for its function, but it is used for functional surfaces, but it does not have a thin film layer, so it is certainly not used for tarpaulin = laminated sheet. Two: Use as a material instead of polyvinyl chloride = The laminated resin sheet formed is used for joining: i :: ί The degree of heat is large and the heat treatment can be easily performed. Even if it is a biodegradable plastic material, there is a problem in sewing or foot strength, and a structure capable of maintaining strength and having a soft fusion bonding process is desired. In view of the aforementioned application, the present invention provides a laminated resin sheet that is biodegradable as a whole, and a biodegradable laminated resin sheet. In addition, another aspect of the present invention is: An object is to provide a laminated resin sheet having excellent laminated sheet strength, peel strength, and even high-frequency welding and laminated peel strength of 180 degrees after processing and shear peel strength, which are biodegradable, and Biodegradable shaped article. SUMMARY OF THE INVENTION The biodegradable laminated resin sheet according to the present invention is composed of the following. That is, a resin base cloth for reinforcement and a resin laminate laminated on both sides of the resin base cloth are formed to form the resin.

200303264 V. Description of the invention (4) ___ The base cloth and the aforementioned resin laminates are laminated resin plates made of biodegradable plastic and biodegradable. The structure can be formed in this way. Because the overall laminated resin sheet has properties, the whole laminated resin sheet shows that it can be decomposed by the product, and the resin base cloth and the resin laminate are fused and formed. S fire. Furthermore, it is convenient to use the biodegradable laminated resin sheet.
