Description

Starch container structure with silicone layer

This creation is about starchy containers, especially a starchy container structure with a silicone layer. It can meet environmental requirements at the same time and be used in high temperature environments.

Generally, the starchy foaming material is composed of at least 50% to 90% starch material, at least 0.5% to 5% foaming agent, at least 0.2% to 3% stabilizer, and at least 5% to 25% fiber reinforcement. The agent and 5%~40% of the filler powder are combined, and the mixing environment must be carried out under high humidity environment (such as relative humidity higher than 80%), and the starchy foaming material is kneaded to form a block. In order to uniformly disperse the moisture in the starchy foaming material, the kneading action must be repeated continuously until the surface hardness of the starchy foaming material reaches an appropriate value (about 10 HA to 20 HA).

Common starchy materials come from potato starch, corn starch, tapioca starch or other vegetable starch. Because of the poor cohesiveness of starch granules, it is necessary to add water to make it a plastic block, so water is similar to the role of plasticizer. When the starchy foamed material is placed in a molding space and heated to 100 ° C at the same time, the moisture contained in the starchy foaming material gradually evaporates to form a plurality of pores, thereby forming a porous starchy container. structure.

The starch foaming material and its products can be completely biodegraded after use, and can realize garbage composting and harmless treatment. Biodegradable in the presence of microorganisms in suitable moist soil, fresh water, seawater, and activated sludge (according to EN13432 Standard Part 2) Form compost. More than 90% of starchy foaming materials have been successfully converted to carbon dioxide, water, energy and biochar in just 80 days.

In addition, the starchy foaming material can also be incinerated. A detailed test report from the National Plastics Quality Supervision and Inspection Center in Beijing, China shows that CO2 emissions per ton of ordinary plastics (such as polypropylene (PP)) are 3.13 tons, and net CO2 emissions per ton of starchy foaming materials are 0.6. Tons, so only 10-20% of the carbon dioxide emissions of traditional plastics can effectively reduce carbon dioxide emissions. In addition, only non-toxic fumes and white residues are produced when burned, and the residue can be used as a fertilizer.

Traditionally, paper is used as a food container. Generally, the paper machine is not a good biological material. In addition, in the prior art, in order to make the paper cup can withstand moisture, PP or PE is applied to the paper cup for waterproofing, but the materials themselves are It is a plasticizer that has an adverse effect on the human body. Furthermore, it cannot be decomposed in nature, so it pollutes the environment.

The inventors have used such materials in large quantities for the production of food containers based on years of research and development of starchy materials. However, the starchy material itself does not have a waterproof function, and when it encounters water or other liquid, it is easily softened to cause deformation or leakage of the liquid. Therefore, the food containers manufactured by the conventional starchy materials can only be used for containing dry foods, and are not suitable for filling liquid foods, thereby greatly limiting the scope of use of such containers.

However, such materials have environmental advantages. When discarded in nature, they will decompose and return to nature without causing environmental problems. Applicants therefore wish to be able to promote such containers to enable them to hold liquids.

Therefore, the present invention hopes to propose a brand new starchy container structure with a silicone layer to solve the defects of the prior art.

Therefore, the purpose of the present invention is to solve the above-mentioned problems in the prior art, and to provide a starchy container structure with a silicone layer, which is attached to the surface of the starchy container to make a starchy container which is not waterproof. Produces a short-term waterproofing effect. Moreover, in nature, the outer layer of the silicone rubber and the starchy container can be naturally decomposed and returned to nature without polluting the environment. Therefore, when the starchy container is coated with the outer layer of the silicone, the liquid can be contained, and the reuse rate is also improved. This allows the container to be used a greater number of times. On the one hand, it reduces the cost of use, and on the other hand, it also reduces the damage to the environment. The biomaterials and silicones used in this case will not cause pollution on the one hand, and will not cause adverse effects on the human body, so the utility is far superior to the paper cups with PP or PE in the prior art. In addition, the outer layer of the silicone rubber in this case can withstand high temperatures above 250 °C. Because the medical use must withstand high temperature sterilization, the traditional container can withstand a temperature of 120 ° C using plastic materials such as PE or PU. In this case, a layer of silicone is coated on the starch container, so the whole can withstand The temperature can be raised to a high temperature of 250 ° C or higher, so the medical device packaged in the container of the present application can be used in a medical environment that is sterilized by high temperature, which cannot be achieved by conventional conventional techniques. In order to achieve the above object, a starchy container structure having a silicone layer is proposed, comprising: a starchy container, which is mainly made of starchy material; and an outer layer of silicone rubber attached to the surface of the starchy container; The outer layer of the silicone rubber is used to make the starchy container which is not waterproof enough to produce a short-term waterproofing effect; in addition, the outer layer of the silicone rubber and the starchy container can be naturally decomposed without polluting the environment; The rate is also increased; the starchy container structure can be used more often; on the one hand, the cost of use is reduced, and the damage to the environment is also reduced.
