The above-mentioned components, as well as other features and advantages of the present invention, will be more prominent after reading the contents of the embodiments and the drawings: The first drawing is a schematic diagram according to a preferred embodiment of the present invention.

The present invention will be described in detail below in conjunction with its preferred embodiments and the accompanying drawings. It should be understood that all preferred embodiments in the present invention are for illustrative purposes only, so except for the preferred embodiments herein, the present invention It can also be widely used in other embodiments. And the present invention is not limited to any embodiment, and should be determined by the scope of the attached patent application and its equivalent fields.

Please refer to the first figure. In one point of view, the present invention discloses an environmentally friendly edible container manufacturing method and its composition. The present invention does not contain plastic, does not harm the human body and the environment, and even has a beneficial additive effect on the human body. The aforementioned food container generally refers to any food or drinking container.

The steps of the present invention include preparing a paper substrate. Please refer to step 110 in the first figure. In the process or after the pulp is completed, natural enzyme or nano silver is added to facilitate sterilization after the product is completed, step 120.

Coating a water-repellent (hydrophobic) material on the above-mentioned substrate, step 130, coating at least one side (or both sides) as the inner (outer) layer coating, water-repellent (hydrophobic) film, for example, The use of hydrophobic materials, including alkanes, oils, fatty substances, or any combination of the above, can increase the durability in the liquid. In one embodiment, coconut oil, palm oil, olive oil, bitter tea oil, linseed oil, etc. may be used. Coconut oil, olive oil, bitter tea oil, and linseed oil are rich in Omega-3. In addition, coconut oil is used in the prevention of cardiovascular diseases and dementia. Coconut oil has the following characteristics: low trans fat content and high proportion of medium-chain fatty acids to help absorption. Most of the fatty acids in coconut oil are medium-chain fatty acids (MCT), which can be directly fed into the liver to be converted into energy and will not accumulate in blood vessels. Rich in lauric acid: Lauric acid is a fatty acid with antibacterial effect. In coconut oil, the content of lauric acid reaches 47%, such a high content is rare in other fats. Strong anti-oxidation ability: The most feared thing about edible oil is repeated frying and cooking, which easily oxidizes and produces harmful substances such as peroxides, dioxin, and PCBs. Coconut oil has a particularly good antioxidant capacity due to its high content of medium chain fatty acids. Good solubility: Coconut oil has small molecules and can be easily dissolved in food, so that the flavor of the ingredients is better.

In one embodiment, the lotus effect can be utilized, and a bionic superhydrophobic substance such as a nanopin film made by Nanotechnology can be used based on this principle. When the contact angle of the cone material is large enough, Cassie's law predicts the large contact angle of the composite material. This special nano film can use borosilicate glass as the main substrate, using CoCl ₂ . A solution of 6H ₂ O or cobalt chloride hexahydrate is deposited in a chemical bath and heated at 60° C. for 24 hours to form a composition having a brucite-type cobalt (II) hydroxide layer CoOH _1.13 Cl _0.09 (CO ₃ ) _0.39 .0.05 H ₂ 0. This step can be implemented before step 130.

After the lamination process, in step 140, the required patterns and colors will be printed on the paper roll again. The present invention uses vegetable ink. It can also be "printed in ink". After printing, the film is coated and the ink is wrapped in the film. Regardless of the printing method, the printing materials of containers that come into contact with food must be food-grade to ensure food safety. Sex. In step 150, the printed paper enters the knife mold to produce a fan-shaped paper sheet, that is, the container wall is unfolded. This piece of fan-shaped paper is fed into the forming machine, and the paper is then rolled into a paper cup shape outside the cup mold. The bottom of the paper cup is then glued. Immediately after the mold pushes the mouth of the cup, the paper at the mouth of the cup is rolled down and fixed with heat to form the edge of the paper cup.

In another embodiment, a film coating step may be applied after forming.

In another embodiment, the coated film may use polylactic acid, which is formed by fermentation and polymerization, and may use poly D-type lactic acid, poly L-type lactic acid, or poly DL-type lactic acid. The starch biomass material further includes any combination of one or more of bamboo, corn stalks, wheat stalks, rice stalks, orange straw, coffee grounds, bagasse. The material further includes cellulose, and the environmental protection film includes poly D-type lactic acid (PDLA type), poly L-type lactic acid (PLLA type), poly DL-type lactic acid or any combination of the above, which can improve heat resistance. The mixing of poly L-lactic acid and poly D-lactic acid can raise the melting point, which is about 50 degrees C higher than that of pure poly L-lactic acid or poly D-lactic acid. Reducing the content of D-type lactic acid in poly DL-type lactic acid can increase the crystallinity, and its heat resistance temperature increases accordingly, which can reach 90 to 120.

The above polylactic acid raw materials come from corn, wheat, sweet potato and other crops, and corn stalks, wheat stems, rice stems, bagasse, etc. can be used as raw materials. Starch is completely extracted from plant raw materials, and after fermentation, polymerization and other processes, it can be completely decomposed by microorganisms, and eventually produce carbon dioxide and water. Mixing two types of poly D-lactic acid and poly L-lactic acid in a specific ratio can make the material properties of poly lactic acid stronger and longer-lasting. In another embodiment, the above-mentioned poly D-type lactic acid (PDLA type) and poly L-type lactic acid (PLLA type) can be taken from poly D-type lactic acid (PDLA type) and poly L-type lactic acid (PLLA type) resins at a low temperature. Polylactic acid is mixed and mixed with nucleating agent and glass fiber, and then molded.

An environmentally friendly edible container, comprising: a base; a container wall, which contains paper components; and a polylactic acid film, which is coated on at least one or both of the inner and outer surfaces of the container wall. Wherein the polylactic acid comprises a mixture of poly D-type lactic acid and poly L-type lactic acid, wherein the amount of the poly D-type lactic acid is less than that of the poly L-type lactic acid.

The advantages of the present invention include the use of a plastic-free coating, which does not cause human burden or pollute the environment, and uses a natural beneficial oil film, which can be hydrophobic and can be absorbed between meals. In this case, natural enzymes were also used for bacteriostasis, while traditional paper cups etc. had no natural bacteriostasis effect.

For those familiar with the art in this field, although the present invention is illustrated above with preferred examples, it is not intended to limit the spirit of the present invention. Modifications and similar configurations made without departing from the spirit and scope of the present invention should be included in the scope of the following patent application. This range should cover all similar modifications and similar structures, and should be interpreted in the broadest possible manner.
