Description

a biodegradable composition

technical field

The present invention relates to a biodegradable composition, especially a biodegradable composition using a starch material, a degradable material and an adhesive material mixed.

Background technique

According to the recent increase in environmental awareness, governments in various countries are also implementing plastic reduction policies to reduce the use of plastic tableware such as plastic straws, plastic spoons or plastic chopsticks or plastic bags. Large plastic waste, and the above-mentioned plastic waste has a great impact on the environment and also increases the cost of recycling and disposal in many countries. Therefore, existing players in the market are promoting the application of environmentally friendly alternative materials such as paper straws and decomposable plant fiber materials. However, when the above-mentioned straws such as paper straws or fiber materials are made, there will be some materials that cannot overcome the temperature and softening problems, and other plastics can be used instead of straws or straws. Stainless steel straws face high recycling and disposal costs.

[Correction 16.10.2020 in accordance with Rule 9.2]
Another example is the "biodegradable straw and its manufacturing method" disclosed in Taiwan Patent Publication No. 200833279, a biodegradable straw and its manufacturing method. Lactic acid is used as raw material, and polyester polyol is added as modifier to produce a biodegradable straw with high flexibility. The biodegradable straw contains 70-99.9 wt% polylactic acid and 0.1-30 wt% polyester polyol. The previous molding step did not focus on the cooling treatment and shaping after the straw was formed, which may cause the straw in the manufacturing process. The production yield problem occurs. In addition, the biodegradable material patented in the previous case is a polymer material, which needs further confirmation for food safety.

Another example is the "environmentally friendly drinking straw" disclosed in Taiwan Patent Publication No. 201838566, an environmental protection straw, comprising: a hollow tube body, wherein the hollow tube body includes a paper component; a hydrophobic material, at least coated with Distributed on one or both of the inner and outer surfaces of the pipe, wherein the hydrophobic material includes alkane, oil, grease, PP, PE or any combination of the above. The hydrophobic material mentioned in the above patent still needs to be further confirmed whether it can be quickly Decomposition and whether it is a harmful substance still needs further confirmation on the environmental impact.

In view of the above shortcomings, the inventor feels that it has not been perfected, so he exhausted his mind to study and overcome it. With his accumulated experience in the industry for many years, he has developed a biodegradable composition, using a starch material, a The degradable material, an adhesive material and a vegetable material are adjusted according to the mixing ratios, so that the biodegradable composition of the present invention can achieve a rapid recovery and decomposition effect and cause the biodegradable composition to not remain harmful. Substances affect environmental pollution.
