Troubleshooting Guides
A production symptom, its likely causes, and what to change.
Anti-block / Slip Masterbatch — Film Blocking Together or Feeding Poorly
Freshly wound film sticks to itself, or converted bags do not open or feed through packaging machines.
Anti-fog Masterbatch — Fog or Water Droplets Inside Greenhouse or Food Packaging Film
Water condenses as droplets inside greenhouse film (blocking light) or food packaging film (blurring product view and dripping onto food).
Anti-static Masterbatch — Static Electricity on Plastic Film or Parts
Plastic parts or film hold a static charge — attracting dust, sticking, or creating ESD risk in electronics packaging.
Desiccant Masterbatch — Bubbles, Streaks, or Splay When Processing Regrind or Wet Resin
Regrind or hygroscopic-contaminated resin produces bubbles, silver streaks, or splay marks in the finished part, and drying is not practical or sufficient.
Flame Retardant Masterbatch — Plastic Burns or Fails a Flame Rating
A plastic part must pass a flame-rating standard (e.g., UL 94 V-0, glow-wire, FMVSS 302) and the base resin fails.
Laser-Marking Masterbatch — Cannot Laser-Mark on Dark or Colored Plastic
A part needs a permanent, high-contrast laser mark (barcode, batch code, logo) and the base resin does not respond — the mark is faint, blurred, or invisible.
Optical Brightener Masterbatch — Recycled or Off-White Plastic Looks Yellow or Dull
Recycled resin or off-spec white looks yellow or gray on the finished part, and the customer wants a cleaner, whiter appearance without going to full white pigmentation.
UV Masterbatch — Plastic Fading, Chalking, or Cracking Outdoors
Plastic parts and films exposed to sunlight lose color, become chalky, or crack after months outdoors.
