Description

Extruded straw with tea powder

The present invention is a straw, especially an extruded straw with tea powder. By mixing different weight percentage substrates, fillers and toughening materials, the straw made is decomposable and environmentally friendly, and at the same time has a natural tea fragrance.

Most of the conventional straws are mainly made of plastic. Although the manufacturing cost is low, their biological indegradability and burning produce black smoke and smell are toxic. They are discarded arbitrarily because of the cost of recycling and reuse, which has caused harm to the ecological environment. Hand-cranked beverage shops can be seen everywhere in Taiwan, causing a large consumption of plastic straws. If the plastic straws are inserted into hot drinks, there is a risk and concern about the dissolution of slight toxicity that is harmful to the human body. Therefore, the inventors are actively looking for alternative materials based on decades of experience accumulated in the industry. After numerous long-term experiments and improvements, they finally found alternative materials.

The present invention discloses an extruded straw with tea powder. A straw extruded by a machine contains a substrate, at least one filler and at least one toughening material; the substrate is 20 to 65 weight percent polylactic acid; the filler 10 to 30 weight percent of tea powder; and the toughening material is 5 to 65 weight percent of polybutylene succinate, polybutylene terephthalate, ethylene-methyl methacrylate Ester copolymer or any combination of the above. Therefore, the straw provided by the present invention can not only replace traditional plastic straws, but can be biodegraded and burned without producing black smoke and odor; It will not dissolve toxic substances when used in hot drinks. In addition to environmental protection, it also reduces the harm to the ecological environment.

The above-mentioned tea powder is ground to 100 meshes and then sieved using the tea powder removed from the tea factory production line, and then dried and dehumidified until the moisture content is below 5%. The tea powder originally discarded by the tea factory production line can be recycled. In addition to recycling and reuse, it will not form excess waste, and it can also enhance the added value of tea, thus achieving the aspirations of green recycling.

The straw can additionally be added with a slip agent to increase the overall stability. The slip agent is calcium stearate, polyethylene homopolymer, erucamide or any combination of the above; the above calcium stearate does not exceed 0.5 phr, polyethylene homopolymer Polymer does not exceed 0.8phr, and erucamide does not exceed 0.5phr.

The straw can additionally be added with a dispersant to avoid sedimentation or agglomeration of the dissolved particles. The dispersant is montan wax, amide wax or any combination of the above; the montan wax does not exceed 1.0 phr, and the amide wax does not exceed 1.0 phr.
