What are the main Biodegradable Film production technologies currently on the market? What are their advantages and disadvantages?

Currently on the market, the production technology of biodegradable membranes is changing with each passing day. These technologies not only focus on the selection of raw materials, but also conduct in-depth research and innovation on manufacturing processes, degradation performance and other aspects.
First, let’s explore starch-based biodegradable membrane technology. This technology uses starch as the main raw material and makes full use of the renewable and biodegradable properties of starch. Starch-based biodegradable films have obvious advantages in production costs and are conducive to large-scale promotion and application. However, its mechanical properties are relatively weak, which limits its application in certain fields to a certain extent. In order to improve its performance, researchers are exploring methods such as adding enhancers and improving manufacturing processes.
Next is polylactic acid (PLA) biodegradable membrane technology. As a completely biodegradable polymer material, PLA has broad application prospects in the field of biodegradable membranes. It has excellent mechanical properties, high thermal stability, and its transparency and gloss are close to traditional plastic films. However, the production cost of PLA is relatively high, which restricts its market promotion to a certain extent. In order to reduce production costs, researchers are making progress in researching new catalysts and optimizing reaction conditions.
In addition, cellulose-based biodegradable membrane technology has also attracted much attention. As a natural polymer material, cellulose has the advantages of being widely sourced and renewable. Cellulose-based biodegradable membranes not only have good biocompatibility and biodegradability, but also have good mechanical properties. However, its manufacturing cost is high, and the degradation process is affected by various factors such as soil conditions and microbial species. To overcome these challenges, researchers are exploring strategies such as new sources of cellulose and improved production processes.
Finally, photo/biodegradable membrane technology is a new technology that combines photodegradation and biodegradation mechanisms. This technology can achieve complete degradation in a relatively short period of time and improve degradation efficiency. However, its production process is relatively complex and requires precise control of the addition amounts of photosensitizers and biodegradants. Furthermore, the rate of degradation is affected by light conditions and microbial activity. In order to improve its stability and controllability, researchers are making progress in researching new photosensitizers and biodegradants, optimizing production processes, etc.
In summary, various biodegradable membrane production technologies have their unique advantages, disadvantages and applicable fields. When choosing which technology to use, factors such as cost, performance, and environmental friendliness need to be considered. With the advancement of science and technology and the deepening of research, we believe that more new, efficient, and environmentally friendly biodegradable membrane production technologies will be available in the future, making greater contributions to environmental protection. At the same time, we also hope that governments, enterprises and research institutions can strengthen cooperation to jointly promote the research and development and application of biodegradable membrane technology and achieve the goal of sustainable development.
