Fresh-Lock® Soft Seal® Zippers
The zipper material must be “crushed” along a package’s side seals. Zippers made with Soft Seal® material require less time, temperature, and energy to crush, so converters achieve high quality seals without sacrificing cycle rates. Soft Seal® material improves converting efficiency and creates better looking side seals that minimize leaking, gaps, and distortion.
All Fresh-Lock® zippers made with Soft Seal® material can be attached in-line using form/fill/seal technology or applied to pre-made bags.
Soft Seal® Zipper Features:
- Less time, temperature and pressure to seal
- Improved side seal appearance
- Soft Seal® material won’t leak, gap, or distort
