Custom Recycled Plastic Clear Pet Scrap Transparent Bottle ...

Food-grade, high-quality clear PET bottle flakes require stringent quality control (QC) to meet FDA/EFSA standards, focusing on high purity (

), moisture below

, and intrinsic viscosity (IV) of

. Key QC steps include advanced sorting (optical/metal), alkaline hot washing, and decontamination to remove PVC, metal, adhesives, and label contaminants.

Key Quality Control Parameters & Specifications

Purity & Contamination: Minimal contamination is essential, ideally
PVC, PP, PE, labels, and adhesives.
Color & Clarity: High-quality flakes must be transparent or water-clear, with low yellowing (low b-value).
Intrinsic Viscosity (IV): Must be maintained at
to ensure suitable molecular weight for bottle-to-bottle recycling.
Moisture Content: Must be controlled to below
, with high-quality standards targeting
, to prevent hydrolysis during reprocessing.
Particle Size: Generally ranges between
for consistent feeding in extrusion.
Acetaldehyde Content: Minimized to prevent flavor alterations in food contact applications.

Optical Sorting: Technologies like NIR (Near-Infrared) sorting are used to remove contaminants, such as PVC, color-coded PET, and even fluorescent or degraded yellowed flakes.
Hot Washing: Utilizing alkaline hot washing (
$is greater than 80 raised to the composed with power C$
) to remove adhesives, labels, and contaminants.
Metal Detection: Sensitive sensors are used to remove metallic impurities from the flake stream.
