Pet flake

Buyers must prioritize IV (Intrinsic Viscosity) levels, typically ranging from 0.70 to 0.85 dl/g, depending on whether the flakes are for fiber or bottle-to-bottle applications. Additionally, monitor PVC content (<50 ppm) and moisture content (<1%), as high impurities significantly degrade the quality of the final recycled product.

Clear/Transparent flakes command the highest market value due to their versatility in dyeing. Blue-tinted flakes are common in packaging, while green or mixed-color flakes are generally relegated to strapping or staple fiber production. Ensure the supplier uses multi-stage hot washing and optical sorting to minimize color contamination.

For food-contact applications, suppliers must provide FDA (U.S.) or EFSA (EU) approvals. Furthermore, look for GRS (Global Recycled Standard) certification to ensure social, environmental, and chemical responsibility throughout the supply chain, and ISO 9001 for consistent manufacturing processes.

High-purity flakes are used for PET sheet extrusion and bottle-to-bottle recycling. Medium-grade flakes are ideal for Polyester Staple Fiber (PSF) used in textiles and carpets. Industrial-grade flakes are typically utilized for non-food containers, plastic strapping, and geotextiles.

Always request a pre-shipment inspection (PSI) by third parties like SGS or Intertek. Specifically, ask for a melt test and impurity analysis report. On Made-in-China.com, prioritize Audited Suppliers who have undergone comprehensive on-site verification of their processing facilities.

PET flakes are usually shipped in 1,000kg to 1,200kg jumbo bags (big bags). Ensure the container is dry and free of odors to prevent cross-contamination. For cost-efficiency, calculate the loading capacity of a 40ft HC container, which typically holds 22-25 metric tons depending on the flake density.

Link your contract pricing to global virgin PET resin indices, as recycled prices often fluctuate in tandem with oil prices and virgin material costs. Negotiate volume-based discounts for annual contracts and seek flexible payment terms such as L/C (Letter of Credit) to secure large-scale transactions.

Be aware of National Sword-style waste import bans; ensure the product is classified as a processed raw material (HS Code 390761) rather than plastic waste. Check for anti-dumping duties that may apply to specific countries of origin to avoid unexpected costs at customs.
