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
