FAQs
What are extrusion straw resins used for?
Extrusion straw resins are specifically designed for straw extrusion using high-speed extrusion lines. These biodegradable resins are ideal for producing compostable straws used in QSRs, cafes, and food delivery packaging. GreenWorks Bio’s resin maintains structural strength during beverage use and transitions efficiently from the plastic state during processing into a finished, flexible form. Unlike conventional plastics, these resins support sustainability efforts across the value chain—from compost garbage bags to mulch film and straws.
How does this resin compare to traditional straw materials like polypropylene or paper?
Compared to paper or polypropylene, Greenworksbio’s PLA+PBAT resin offers better performance in both cold and mildly warm drinks, without becoming soggy or brittle. It exhibits superior heat resistance grades compared to paper and doesn’t compromise on flexibility or safety. Unlike petroleum-based polymers, this best quality resin is certified compostable and can be aligned with brands offering home compost garbage bags, shopping bags, and other earth-friendly packaging. Manufacturers looking for alternatives to brands like Greendot Biopak will find similar or better performance in both durability and compostability.
Can this resin be used on existing plastic extrusion machinery?
Yes, our resin is engineered to run on most straw extrusion and extrusion coating lines with minimal tuning. During processing, the material transitions from a plastic state to a straw using typical rollers, with processing temperatures ranging from 130–160°C, depending on straw diameter and wall thickness.
Is the resin suitable for both straight and flexible straw designs?
Absolutely. Greenworksbio’s extrusion resin is designed for straight, flexible (accordion), cocktail, and smoothie-style straws. We can tailor resin properties such as gloss, moulding behaviour, and rigidity based on the final use. These flexible characteristics also mirror requirements used in other compostable products, such as home compost shopping bags and compostable mulch film, where foldability and strength are crucial.
