The first is to "look", to see if the outer tube of the straw is equipped with no QS; if the straw has color, if there is color, the safety of the straw will be reduced, and the dark color should pay special attention; there is no black spot in the straw Impurities or broken bubbles, as these are characteristics of unqualified products. Secondly, you should "smell" and smell the odor of the scent before the straw is in contact with the beverage. The third thing is to pinch the pinch. If the pipette is pinched, it is flat and has no elasticity. It means that the straw is made of a relatively thin material, the quality is poor, and it is easy to be sucked during use.
Disposable straws are a very inconspicuous thing. People use it when they drink soy milk, milk, drinks, and milk tea. As people pay more and more attention to the condition of food hygiene, the straw as a disposable food product has also attracted everyone's attention. Some breakfast stalls and disposable straws provided free of charge by the cold drink shop are mostly “three no” products.
Made of old plastic
Typical plastic products contain polyethylene and polypropylene, which can produce harmful substances at high temperatures.
The “three no” straws may be processed from recycled waste plastics. Once exposed to high temperatures, they may produce toxic substances that endanger health. The quality of the “three no” plastic straws is definitely problematic. Because of the inferior quality or recycled plastics produced, pigments may be used to cover the impurities. Once you use it to drink juice or hot drinks, harmful substances will dissolve and cause harm to the human body.
The raw materials for the “three no” plastic straws may be industrial grade polyethylene or waste plastics. If consumers use them for a long time, they will damage the human liver and cause blood diseases or nervous system diseases. The more colorful the straws are, the greater the safety risks. If you use this type of straw to drink hot drinks, the harmful substances in the straw will be released, endangering human health.
As early as 2009, China has implemented the national standard for drinking straws. This standard has clear regulations on straw raw materials. It also requires the name of the factory and the health permit number printed on the outer packaging of the straw. There are also specific requirements for temperature resistance. Only straws with the food quality and safety market access mark “QS” can be sold on the market.
The material of the straw is mainly polypropylene, commonly known as PP. The straws produced by regular manufacturers require many processes. The qualified straws made of polypropylene can withstand the high temperature of about 80 °C, and they will not emit plastic smell when heated. Other illegal traders use recycled plastic products to make mixed plastics. The quality of its products is difficult to guarantee.
The straw produced by the regular manufacturer has no toxic and side effects on the human body, but the straw that uses the recycled plastic used for reuse, after contact with high temperature, the toxic and harmful substances in the plastic will dissolve, and at the same time, it does not exclude heavy metal impurities inside, long-term use. Inferior straws can affect a person's liver, causing blood or nervous system diseases, and severe cases can cause cancer.
