9169-HS Water-Based Heat Seal for Paper Packaging
Seal paper mailers and bags with no tape and no extra glue. 9169-HS is our water-based heat seal coating for paper coaters and converters. It activates fast, gives a tamper-evident paper-to-paper seal, and unwinds clean through converting.
Why converters choose 9169-HS
- Strong paper-to-paper bond: typically 2.4 lbf/in on recycled paper to paper.
- Fast, tamper-evident seal: activates quickly on the sealer, and a sealed flap shows if it has been opened.
- Clean unwind: non-blocking through the converting process.
- Runs at speed: its viscosity window is set for smooth, even laydown on high-speed lines.
- Simpler packs: the coating is the closure, so you can drop separate tapes and glues and use less material.
- Recyclability: Passed independent lab recyclability testing in tested paper structures. Recyclability depends on your full package, including the paper, inks, coatings and local recycling systems, so the customer or end user must test to confirm it for their specific use. Final recyclability is determined by the customer or end user, not by Cattie Adhesives.
