How can recycled packaging materials affect a packaging machine?
• Recycled film thickness varies over ±10%, so raise heat-seal jaw temperature 5-10°C and shorten dwell time.
• Low-stiffness recycled board jams feeding; reduce cycle rate and add vacuum suction for infeed.
• Recycled material friction fluctuates; use servo-driven closed-loop film tension control to prevent tracking drift.
• Contaminants stick to the heat-seal jaw; clean it each shift and verify seal strength ≥15N/15mm.
• Run a FAT before purchase; confirm changeover time and reject rate within 1.5x of virgin film.
