Description

XT repair (more) Α啐 page change, invention description: [Technical field of the invention] The present invention refers to a method for synthesizing a decomposable packaging container by a synthetic paper process, which means that a moisture barrier film is formed on a paperboard as a synthetic paper. The method of production is generally used for food packaging. "Tolerance, commonly known as disposable tableware, this creation is on the single or double-sided surface of the cardboard surface - anti-fine, the hybrid film is biodegradable material. [Prior Art] According to the new patent application No. 094206557 “Decomposable cardboard for food preparation” proposed by the applicant in this case, the application patent scope is 1 separate item and 2 subsidiary items. The independent item package & is provided on the surface of the paperboard of the base paper roll with a biodegradable pLA (polylactic acid) moisture-proof film coated on the surface to provide a cuttable paper-making utensil. The subsidiary items are: bio-ageable age film can be a kind of PE moisture-proof film. The biodegradable moisture barrier film can be a starch layer. The above-mentioned PLA moisture-proof membrane structure on the surface of the paperboard mainly has the characteristics of conforming to the food-grade H regulations, and can be automated when the production is performed. In the initial cultivation, the system directly feeds the thin tube to read the convenience of subsequent storage, transportation, and cutting; however, in the process of laminating, the finished product is cold when the biodegradable material is film-like. The empty county produces crystallization, so when the temperature in the waste room drops due to climate change, the organism can be separated from the lining body. Some of the crystal particles and bubbles are generated in the film body before the paperboard, so that the film body is coated on the cardboard/ The surface of the combined sister made by the press-fit system is prone to the fatigue of the film body. SUMMARY OF THE INVENTION [SOLVED] Solving the problem of the upper surface: the disadvantage of the sloping work pressure, the present invention provides a process for the decomposition of the packaged synthetic paper, which is on the end surface of the original paper roll, PLA, or starch-based biodegradable material f 'after heating into liquid, and then made by T_DIE (extrusion / hot pressing) film-forming unit - moisture-proof film, the moisture-proof film source is continuously applied to the cardboard The surface allows the moisture-proof film to be closely integrated with the fibers on the paper surface. Main features: After the film is coated on at least one surface or both surfaces of the paperboard, the double-metal roller clamps are placed on the surface. The metal roller strongly presses the moisture-proof film and paperboard after bonding, so that each of them can maintain the same thickness and thickness, ', σ δ can be used to clamp the moisture-proof film before the slope The clock that is crystallized due to the local age of the edge, or the part of the bubble that is trapped in the shape of the air after the cardboard is flattened, and finally another roller. And 'roll the cold part' and read dry The device is dried and shaped, that is, after the finished product reel is received, the λ wire is combined. Heteroaryl kinds of food containers with green paper container of paper process. Wherein, the above-mentioned bimetal roller can be an iron roller, and can be connected and purely in the bimetal roller (10), and the heating temperature of the bimetallic roller can be maintained, so that the pressing process can bring the creature. The decomposable moisture-proof membrane maintains the melting temperature of the thawing-reducing crystallization reaction of biodegradability. [Embodiment] The following drawings are further described in conjunction with the preferred embodiments of the present invention, and are intended to enable those skilled in the art to practice the invention. First of all, please refer to the first figure, the decomposable packaging container of the present invention uses a synthetic paper to make a good manufacturing flow, and further elaborates the manufacturing process of the present invention as follows: Before explaining the manufacturing process, The material of the moisture-proof film used in the present invention is as follows. The material of the moisture-proof film is made of a biodegradable plastic material, which is made of all biodegradable polyethylene (PE) materials, or similar to polyethylene (PE). Effective material, this creation emphasizes the use of Biomax PE produced by DuPont Group of the United States or biodegradable polyethylene (pE) particles produced by Taiwan Far East Textile, or the use of all biodegradable PLA (PLAPOLYLACTIC ACID) material 'named' Lactic acid, such as bio-produced by Nature Works LLC

Decompose polylactic acid (PLA) particles...etc.; or use all CORN STARCH materials. In the present invention, the paper 1 of the paper roll (Prepering) is preheated, and then subjected to a Corona treatment as the first system 1334459, all biodegradable polyethylene (PE) or polylactic acid ( PLA) Particles (called: green plastic) or starch (CORN STARCH) Any one of the materials is placed in a funnel, heated by a screw (EXTRUDER), and then passed through a coating machine (T-DIE) The device transports the molten material to the laminating unit a to form the moisture-proof film 20 of the lamellar film layer as the second process.

The moisture-proof film 20 made of biodegradable polyethylene (PE), or polylactic acid (pLA) ' or starch in the above process is dripped on the original paper roll which has been preheated and electrostatically treated in the above first process. The cardboard is placed on a surface, and then it is pressed with a strong rolling (squeezing) pressure between the bimetallic rollers B and C, so that the moisture-proof film 2〇 can be closely adhered to the surface of the fiber of the cardboard, and then electrostatically treated (c(10)〇 Treatment ) The cardboard 10 is attached with a capillary hole made of biodegradable polyethylene (PE) or polylactic acid (10), and finally rolled into a bundle of paper rolls for cutting. After the flat sheet is formed, it is convenient for paper-made disposable table makers of various sizes.

Wherein the above-mentioned bimetal rollers B and c can be provided with a connecting heater inside thereof, thereby providing a heating temperature of the metal miscellaneous B, c_maintaining, so that the biodegradable process can be decomposed during the pressing process. The moisture-proof film 2G continues to maintain a certain temperature of f to reduce the bio-separable anti- 2G production of the junction: - the bi-metal roller B, C, in the preferred embodiment of the invention '疋" Roller, or stainless steel roller. 8 1334459

The coating is provided with a Weilong anti-staining layer, thereby preventing the film 2 () from sticking to the surface of the metal roller C in the process of rolling, and speeding up the rolling process.

For the finished product structure after the above process is improved, please refer to the second drawing, which is a cross-sectional view of the product of the decomposable packaging capacity _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ A moisture-proof film 2G made of biodegradable starch, or polyethylene (10)) or polylactic acid (pu). In addition, as shown in the third figure, it is a cross-sectional view of the finished product, a kind of decomposable packaging capacity, and a modified product. The main description shows that the moisture-proof film can be coated on the upper and lower sides of the cardboard 10 by laminating. The structure is mainly made up of the moisture-proof film 20 made of the material of the paperboard 1G-surface surface, the biodegradable powder-killing, the silk-thin (four), the silk lactic acid (10). After the film, the laminating process of the other side of the cardboard 1() can be continued, that is, the double-sided cardboard 1G has a structure of covering the moisture-proof film 20; the 俾 is used to reduce the use of high-priced green plastic, thereby effectively saving manufacturing costs. To prevent the pollution of the land, the adhesion and other improvements. To sum up the above-mentioned examples of the practical implementation of the 'Innovative Structure', the structure of the creation is fine, so that any change that can achieve the equivalent structure is included in the creation of the nuclear. It is guaranteed by the scope of patent application. In summary, the implementation of the structure of the invention is indeed innovative and practically effective. It is supposed to be in the essence of the invention patent, and the handle is clear, 9 1334459
