Problems solved by technology

The price of PLA straws is high, and due to the influence of its own material, the straws are brittle, easily brittle and cracked by external force extrusion, the storage time is short (long-term storage is easy to degrade, performance decline), low temperature brittleness and other problems; paper straws also exist The processing of raw materials pollutes the environment, consumes a lot of energy, and cannot be soaked in liquid for a long time.

Abstract

The invention relates to the field of straws, in particular to a full-bio-based toughened straw and a production process thereof, and provides the full-bio-based toughened straw which is characterizedby comprising the following components in parts by weight: 30-50 parts of biopolyethylene, 30-40 parts of modified starch, 1-5 parts of a coupling agent, 3-10 parts of a biological plasticizer and 1-3 parts of a lubricant. The problems that a PLA straw is high in price, brittle due to the influence of the material of the straw, prone to brittle cracking due to extrusion of external force, short in storage time, high in low-temperature brittleness and the like are solved; the paper straw also has the problems that the raw material processing environment is seriously polluted, the energy consumption is high and the straw cannot be soaked in liquid for a long time. The production process is simple and controllable in process and low in cost, the environment cannot be polluted no matter fromthe raw materials, the production process or the finally obtained product, safety and environmental protection are truly achieved, and the straw quite conforms to the sustainable development concept.

Description

technical field [0001] The invention relates to the field of straws, in particular to a bio-based toughened straw and a production process thereof. Background technique [0002] With the improvement of people's living standards and the quickening pace of life, the consumption of various liquid foods such as milk and beverages is increasing, and straws are generally used for these foods. Because it is more hygienic to use a straw without touching the cup; in addition, drinking beverages with a straw is good for the health of the teeth and has an effect on teeth whitening; and the straw is cheap. Suction straw is favored by people because of its convenience, hygiene and cheapness as a disposable article. [0003] At present, there are several types of straws: degradable and non-degradable; non-degradable straws are mainly processed from ordinary PP, PE and other materials, and there are environmental problems. tool use. Therefore, biodegradable straws are born due to luck. ...
