The Future of PET Recycling in a Circular Economy
In a denser world of circular economy and sustainability, PET recycling becomes of imperative concern in preventing plastic waste and acquiring quality material from post-consumer products.
Grateful to decades of innovation, Luigi Bandera S.p.A. has become a leading brand in PET extrusion lines, designing complete lines to transform recycled PET flakes into food-grade films, sheets, and packaging.
However, food-contact grade requires advanced extrusion technologies that provide purity, uniformity, and mechanical strength. That’s where Bandera’s technology comes into play.
From Bottle-to-Bottle: Closing the PET Loop
Bottle-to-bottle PET recycling is the most developed stage of circularity.
By recycling post-consumer PET bottle flakes into new packaging products, Bandera’s extrusion lines are assisting in offering a true closed-loop recycling program.
Key Advantages of Bandera PET Recycling Lines:
- Complete extrusion lines for sheet and rigid film production
- Food-grade certified output, compliant with international safety standards
- Integration of degassing and deodorization systems to remove VOCs and contaminants
- Energy-efficient twin screw extruders for consistent melt quality
- Automatic screen changers and melt pressure control for process stability
These features allow manufacturers to produce food-contact PET sheets with excellent transparency, strength, and purity, ideal for thermoformed trays, cups, and packaging films.
Technologies Behind High-Quality PET Extrusion
Bandera’s PET extrusion lines integrate a range of state-of-the-art technologies that focus on enhancing process efficiency and product quality.
Twin Screw Extruders for Recycled PET Flakes
Twin screw extruders deliver fine mixing and homogenization of recycled PET flakes. They are particularly ideal for the processing of post-consumer materials with variable moisture and viscosity.Double Degassing and Deodorization Units
Removing volatile organic compounds (VOCs) and odors is essential in PET upcycling. Bandera’s double degassing technology guarantees a clean melt, improving both visual and olfactory quality.
Melt Filtration and Automatic Screen Changer
Continuous filtration systems remove solid impurities, while the automatic screen changer minimizes downtime, ensuring uninterrupted, high-throughput production.
Energy-Efficient Pelletizing Lines
Bandera offers high-quality pelletizing systems capable of transforming post-consumer PET waste into homogeneous pellets, suitable for both extrusion and injection molding applications.
Circular Economy Impact through Sustainable PET Upcycling
The global market for sustainable packaging is growing every day, and upcycling PET is a smart move.
Compared to traditional downcycling, upcycling enhances post-consumer PET to commodities with equal or higher value than virgin resin.
By adopting circular economy PET technologies, companies can:
- Reduce carbon emissions and energy consumption
- Comply with EU and FDA food-contact regulations
- Reuse up to 100% of post-consumer PET in new applications
- Strengthen brand sustainability credentials
Luigi Bandera’s extrusion lines make circular PET production both economically viable and environmentally responsible — a win for both industry and planet.
Applications of Recycled PET Extrusion
Recycled PET can be transformed into a wide range of high-value products through Bandera’s extrusion systems.
Here are some common applications:
| Application | Material Type | Extrusion Output |
| Food packaging trays | Post-consumer PET flakes | Food-grade PET sheets |
| Thermoformed cups | Recycled PET pellets | Rigid film |
| Industrial films | PET regrind | Flat die extrusion |
| Blister packaging | Bottle flakes | Multilayer PET film |
| Sheet for thermoforming | PCR PET | Clear sheet extrusion |
This versatility makes PET recycling extrusion lines a valuable investment for industries in packaging, thermoforming, and rigid film production.
