Under the concept of environmental protection, how can the pet poop bag making machine ensure that the raw materials are 100% degradable and meet the performance standards?

At a time when environmental awareness is growing, pet poop bags are disposable products, and their degradability has attracted much attention. The pet poop bag making machine shoulders a major mission. It is not easy to achieve 100% degradable raw materials and meet the performance standards, but it is imperative.
First of all, material selection is the key starting point. The manufacturing machine needs to accurately adapt to mainstream degradable materials such as polylactic acid (PLA) and starch-based plastics. PLA is derived from renewable plant resources, has good thermal stability and processability, and can be gradually decomposed into water and carbon dioxide in a composting environment. Starch-based plastics are based on natural starch, are relatively affordable, and have a faster biodegradation rate. The feeding system of the manufacturing machine should be precisely designed based on these material characteristics to ensure uniform feeding and avoid affecting the quality of bag molding due to raw material accumulation or uneven flow rate.
Process control is the core link. Parameters such as temperature, pressure, and extrusion speed are like precise dance steps and need to be perfectly matched. Taking the extrusion process as an example, the appropriate high temperature can fully melt and plasticize the degradable raw materials, but if the temperature is out of control and too high, it will cause the molecular chain of the material to break and reduce the toughness of the bag; insufficient pressure will not compact the material, resulting in micropores and loose structure in the bag, affecting the waterproof and leak-proof performance. The intelligent control system equipped with the manufacturing machine monitors in real time and uses sensor feedback to fine-tune parameters to ensure that the thickness of each batch of bags is uniform and the strength is reliable, which can not only withstand the weight of pet feces, but also degrade as scheduled in the natural environment.
The quality inspection system is like a loyal guard. From the entry of raw materials into the warehouse to the exit of finished products, multiple inspection checkpoints are checked layer by layer. For raw materials, advanced methods such as infrared spectroscopy and differential scanning calorimetry are used to verify the purity of ingredients and degradation characteristics; in the semi-finished stage, the mechanical properties of the bag are checked through tensile tests and puncture resistance tests; in the finished product stage, natural scenes such as soil burial, light and rain are simulated to accelerate aging tests to ensure that the actual degradation cycle meets environmental protection standards and prevent "pseudo-degradation" products from entering the market.
Equipment innovation is also indispensable. Develop a new screw structure to enhance the mixing and propulsion efficiency of highly viscous biodegradable raw materials; improve the die design to make the discharge more uniform and smooth, and reduce edge defects. At the same time, the manufacturing machine manufacturer works closely with the material supplier to feedback the production end problems and work together to optimize the material formula, so that the pet feces bag manufacturing process is closely linked to environmental protection and performance, paving a clean and sustainable road for urban green pet raising.
