Barrier Bottle Removal ≥98%: DATABEYOND Launches Industry-First 3D Sorter with Barrier & Fluorescence Fusion

Yellowing in PET flakes stems from two root causes: suboptimal washing processes and contaminated feedstock.

I. Process-Induced Yellowing

Four key factors drive yellowing during washing: temperature, duration, alkali concentration (pH), and chemical formulation. Operator practices further influence outcomes.

Example: Flat-bottomed wash tanks accumulate sediment, causing prolonged exposure that yellows flakes during discharge.

Example: Uncalibrated temperature sensors create >10°C deviations, resulting in ineffective cleaning and uniform yellowing.

II. Feedstock Contamination

Barrier bottles remain the most problematic among yellowing sources (oil containers, adhesive-laden bottles, recycled flakes, UV-degraded bottles). Barrier bottle variants have surged from 2-3 brands to dozens, with new beverage products continually entering the market.

Data Spotlight: Barrier bottles comprise 8% of unwashed bales in Henan① and >10% in coastal regions②. (Source: DATABEYOND Bale Inspection Reports)

III. The Barrier Bottle Challenge

Unwashed bale processors: Pre-label removal AI sorters identify branded barrier bottles but miss new/unknown variants, leaving contamination risks.

Washed bale processors: Label-free barrier bottles are visually identical to premium flakes—undetectable by AI optical sorters or manual UV inspection (minimal fluorescence). This forces reliance on upstream quality control.

IV. Game-Changing Solution

DATABEYOND’s FASTSORT-BARRIER-FLUO 3D Optical Sorter revolutionizes barrier removal:

Replaces conventional fluorescence-only systems (effective on <5% of barrier bottles like "East Leaf" or "Vitamin C" brands).

Integrates proprietary BARRIER spectral sensors and FLUO fluorescence detection.

Achieves ≥98% accuracy on label-free barrier bottles while simultaneously removing fluorescent, low-fluorescence, and UV-degraded bottles.
