  Innovative biodegradable extruder technology facilitates the recycling of PET bottle pieces   With the increasing global awareness of environmental protection, plastic recycling has become a hot topic. Especially in the packaging industry, PET (polyethylene terephthalate) material is widely used in the manufacture of beverage bottles, films and other products due to its light weight, durability and transparency. However, recycling of PET materials has been a technical challenge. Recently, an innovative biodegradable extruder technology has provided a new solution for the recycling of PET bottle flakes and films.   PET materials are widely used in many industries because of their excellent physical and chemical properties. It is not only used in the production of beverage bottles, mineral water bottles, energy drink bottles, iced tea bottles, but also for more sensitive drinks such as beer, wine and juice bottles. PET is also widely used in the textile, electronics and automotive industries, where it is favored for its durability and chemical stability. For example, in the automotive industry, PET is used to make windscreen brush arms, gear boxes, headlight retainers, hoods and other components.   PET material has a melting point of approximately 267°C, which allows it to remain stable at high temperatures while having good heat sealing properties, which is essential for the manufacture of beverage bottles and other packaging materials that require heat sealing. During the extrusion process, the PET material needs to be heated and processed within a specific temperature range to ensure its physical properties and the quality of the final product.   A biodegradable extruder is a device specifically designed to handle biodegradable plastics. It biodegrades plastic materials by mechanically mixing, heating and molding them, which are typically composed of organic biomass such as starch, cellulose and protein, or synthesized from renewable biobased monomers. The extruder uses twin-screw extrusion technology to mix biopolymers efficiently and uniformly, resulting in the production of high-quality biodegradable plastic particles.   In the PET bottle sheet recycling process, the extruder first breaks and cleans the collected PET bottle sheet to remove impurities such as labels and caps. The debris is then heated to its melting point, usually between 260°C and 280°C, turning it into a molten state. In the molten state, the PET material is transported and mixed through the screw of the extruder, ensuring the uniformity and fluidity of the material. The molten PET is then extruded through a specific mold to form the desired shape, such as a preform for a water bottle or other packaging material. Finally, these preforms are cooled, cured and cut into the final product.   With this advanced biodegradable extruder technology, the recycling of PET bottle flakes and films becomes more efficient and environmentally friendly. This not only reduces the reliance on petroleum-based plastics, but also helps reduce the environmental impact of plastic waste and promotes the sustainable development of the plastics industry.   With the advancement of technology and the improvement of environmental awareness, biodegradable extruders have broad application prospects in the recycling of PET bottle flakes and films. This technology not only improves the quality and performance of recycled materials, but also provides the plastics industry with a sustainable and environmentally friendly production method. As more innovative technologies emerge, there is reason to believe that plastic recycling and reuse in the future will become more efficient and environmentally friendly.

  The latest technological breakthrough in the plastic extruder industry has significantly improved the processing efficiency and environmental performance of polyamide (nylon, PA) materials.
