PLA straw rise, paper straw only 10% of the market, the new national standard implemented on June 1!

Release time:


Recently, Shenzhen Satellite TV reported the change in the straw market in the year since the implementation of the "plastic ban". When the "plastic ban" was first implemented, paper straws were all the rage for a while, but they were easy to soak, soft and tasty and other hard injuries, causing milk tea shops to abandon them and choose PLA degradable straws. Now paper straws may only have less than 10% of the market.

Liu Guigang, general manager of Guangdong Zhongsu Degradation Materials Co., Ltd., one of the founders, said in an interview that recently, Guangdong Zhongsu Company sold more than 100000 PLA straws in the Pearl River Delta region every day, and 60% of its customers came from Shenzhen. This action in Shenzhen shows that Shenzhen will immediately start to promote PLA degradable straws, especially the implementation of the new national standard in June, and will continue to pay close attention to it.

The demand for degradable straws in Shenzhen has suddenly increased, which has a lot to do with the implementation of supervision. At the end of March, the Shenzhen Market Supervision Bureau issued a notice that the catering industry banned non-degradable disposable tableware, etc., and will carry out special law enforcement. It is necessary to urge catering service providers to implement the national plastic restriction requirements, reduce the use of disposable tableware, and promote catering service units. The use of non-degradable disposable plastic tableware and disposable plastic straws, and the use of disposable non-degradable plastic bags for packaging are not allowed. Encourage takeaway units to practice green takeaway and use degradable and recyclable tableware.

The national standard for biodegradable straws will be implemented on June 1, 2022

Biodegradable plastics excluding PE, PP

In November 2021, the State Administration of Market Supervision and Administration and the State Standardization Administration issued an announcement, "GB/T 41010-2021 Biodegradable Plastics and Products Degradation Performance and Identification Requirements" and "GB/T 41008-2021 Biodegradable Drinking Straws" The two national recommended standards will be implemented on June 1, 2022. These two standards define biodegradable plastics and circumvent the use of traditional resins such as PE and PP in materials.

For the most concerned biodegradability, the standard requires:

The biodegradation rate shall meet the following requirements:

a) The relative biodegradation rate shall be greater than or equal to 90%, and the absolute biodegradation rate of a single organic component with a component greater than or equal to 1% in the material shall be greater than or equal to 60%;

B) if the biodegradable plastic and the product are composed of mixture or multiple materials, the organic components with less than 1% of the components shall also be biodegradable, but the ability proof may not be provided, and the total amount of each component with less than 1% of the components shall be less than 5%.

Note: Organic components with components greater than or equal to 1% shall be able to provide biodegradability certificates such as inspection reports. For organic components with component content less than 1%, the corresponding inspection report of the product or self-declaration of the enterprise can be provided for biodegradability.

The biodegradation rate is required in paragraph A. The relative biodegradation rate of PP and PE degradable products can reach 90%, but pure PP and PE do not have this function. The use of "and" in the text of the new standard restricts PP and PE from being included in the list of biodegradable plastics.

In fact, the biodegradable polymers listed in GB/T 41010-2021 include starch, cellulose, PLA, PBAT, PBS, PBSA, PCL, PPC, PGA, etc., but do not include the film resin PE and injection molding resin PP, which are currently the most used.
