How to ensure the purity and biodegradability of raw materials during the production process of Biodegradable Film & Bag?

In the production process of Biodegradable Film & Bag, it is crucial to ensure the purity and biodegradability of raw materials. Here are some key measures:
1. Ensure the purity of raw materials
Choose high-quality raw materials: Choose high-quality biodegradable raw materials, such as polylactic acid (PLA), polyhydroxyalkanoate (PHA), etc. These raw materials should come from reliable suppliers and undergo rigorous screening and testing to ensure their purity and quality.
Strict cleaning process: During the production process, all equipment and tools must undergo strict cleaning and disinfection procedures to prevent any possible contamination from impurities. This includes regular cleaning of equipment, changing filters, using detergents, etc.
Avoid the introduction of impurities: During the entire production process, it is necessary to try to avoid any possible impurity contamination. For example, keep the production environment clean and avoid dust, moisture and wear particles on equipment in the air.
Quality testing: Before the raw materials are put into storage and used, quality testing is carried out, such as using high-performance liquid chromatography (HPLC), mass spectrometry, elemental analysis and other instruments to conduct qualitative and quantitative analysis of the purity of the raw materials.
2. Ensure biodegradability
Choose raw materials with biodegradable properties: Choose raw materials that have been proven to have good biodegradable properties. These raw materials can be quickly decomposed into harmless substances such as carbon dioxide and water under the action of microorganisms.
Optimize the production process: By optimizing the production process, such as controlling reaction temperature, pH value, solvent selection, reaction time and concentration, etc., we ensure that biodegradable raw materials can fully react and produce high-quality biodegradable films and bags.
Add biodegradation aids: When necessary, some biodegradation aids can be added to improve the biodegradation performance of the product. These additives can accelerate the microbial degradation process and make the product decompose into harmless substances faster.
Quality control and testing: Quality control and testing are carried out at all stages of production to ensure that the biodegradation performance of the product meets standard requirements. This includes the use of biodegradation testing equipment and methods to assess how quickly and to what extent a product degrades.
Through the implementation of the above measures, the raw material purity and biodegradability of Biodegradable Film & Bag can be ensured, thereby improving product quality and reliability.
