Starch-based plastic certification system
In recent years, the environmental performance of bio-based products has been gradually recognized at home and abroad, and the application fields of bio-based materials have been greatly expanded. The bio-carbon content of bio-based materials is an important feature that distinguishes them from ordinary plastics. Bio-carbon content is defined as the percentage of biochar in organic carbon (including biochar and fossil carbon) in products. Since bio-carbon is a new carbon, it does not pollute the environment, so it has a good environmental effect. The bio-carbon content detection standards include ASTM D6866-08: Test method for determining the biological content of solid, liquid and gas samples by radiocarbon analysis and the liquid-flash counter method for bio-based content determination in Chinese GB/T29649-2013 bio-based materials. Since the contemporaneous organisms contain equal amounts of radioactive carbon, the principle of ASTM D6866 is to measure the biobased content of the sample in any state by means of this property of the organism; this method can be used to determine any biobased products and organisms. The exact percentage of biobased or renewable material contained in the base blend.
In 2009, the Belgian authoritative certification body Vincotte issued the world's first batch of OK Biobased star certification products certification, the authoritative level certification of the bio-carbon content of bio-based materials, and also provides a reliable product quality for the bio-based materials market. Third party evaluation. OK-Biobased is Belgium's environmental label for bio-based low-carbon products. Bio-based plastics manufacturers can certify their labels on product packaging or products to differentiate them from ordinary petrochemical products. It defines bio-based materials based on bio-carbon content and evaluates them as a percentage of bio-carbon content and total carbon content. The standard is ASTM D6866, which is a star-based distinction between materials and is the EU's authoritative bio-based material certification mark. The OK Biobased logo uses an asterisk to distinguish the environmental rating of the product. A certified product has a 1 star mark to prove that its product contains 20% to 40% of biochar, 2 stars are 40% to 60%, 3 stars are 60% to 80%, and 4 stars are more than 80% bio-carbon content. product. Vincotte's OK Biobased certification aims to help companies or distributors improve the market competitiveness of renewable products and guide consumers to better choose environmentally friendly products.
To encourage the development of biobased materials and products, the US Department of Agriculture has implemented a biological priority program. The program has two programs, a government procurement priority plan and a voluntary identification program for consumers. The former was in 2002 to encourage the development of bio-based products, while the latter was released in 2008. The purpose of the Bio-Priority Program is to stimulate the consumption of biomass products in the United States. Federal government agencies and their contractors prioritize the purchase of products with the highest biomass content. If the product meets the minimum standards for bio-based content in the US Department of Agriculture's bio-based product list, any factory or distributor can participate in the program, and the certificate label issued by the agency can be affixed to the product packaging.
The international certification of biodegradable plastics includes Belgian OK Compost certification, German Compostable certification, and US BPI certification.
OK Compost is a compostable certificate named "OK Compost" issued by the Belgian certification body AIB-Vincotte Group after testing according to the test standard for biodegradable materials EN13432 or ASTM D6400. OK Compost certification aims to help companies or distributors improve the market competitiveness of fully degradable products and guide consumers to better choose environmentally friendly products.
Compostable certification is the certification of biodegradable products by DIN CERTCO, a joint certification body of TUV Rheinland Group and Deutsches Institut fr Normun (DIN). The authentication ID is the “seeding” logo. Compostable certification helps buyers to select products from a wide range of suppliers and manufacturers for quality, safety and environmental protection. At the same time, products with the Compostable logo indicate that they have successfully passed the testing and evaluation of an authoritative third-party organization, which helps to enhance the customer's purchasing confidence and effectively promote product sales. And the relevant information of the holder can be inquired on the official website of DIN CERTCO to prevent abuse or forgery of the logo.
BPI is an abbreviation for Biodegradable ProductsInsitute. BPI educates producers, legislators and consumers about the scientific standards for degradable materials through an innovative compostable labeling program. At the same time, a series of procedures are in place to ensure that the relevant products meet the requirements of the standards for degradable materials.
The first batch of Chinese companies that have received OK Biobased certification in Wuhan, China, have obtained four-star bio-based product certification. At the same time, the company's biodegradable materials received OK Compost certification and Compostable certification.
we offer patented full biodegradable film and PVA bag, all products are made by casting equipment, It is different from traditional blow molding products, all blow molding products are non full biodegradable. We can produce pva films and bags in all transparent and various colors.
we also offer organic material full biodegradable film and bags with patented raw material and production Process. our corn based starch-based plastic and bamboo based starch-based plastic get Vincotte OK Biobased certificate.
