6 Essential Tips for Storing Pet Flakes
Recycled Polyethylene Terephthalate (rPET) is at the heart of a circular economy. Once collected and cleaned, PET bottles are transformed into rpet flakes—a high-quality raw material used across industries including textiles, packaging, construction, and automotive. To maintain performance and consistency, how these flakes are stored is just as important as how they are produced. Improper storage can compromise their quality, reduce efficiency in downstream processes, and lead to avoidable losses. Here are six essential tips for storing rPET flakes safely and effectively. 1. Control Moisture at All Times Moisture is one of the biggest threats to rPET flakes. When exposed to humidity, flakes absorb water, which can cause defects like bubbles or discoloration during extrusion or moulding. To prevent this, flakes must be stored in airtight containers or moisture-proof bags. Warehouses should also be equipped with dehumidifiers, especially in humid climates. Proper moisture control ensures...
