In our previous post we explored the sealing relationship between heat, time and pressure, which must be provided in the right combination to produce quality seals.
This post explains how reduced seal widths can increase sealing pressure and help you to: 1. Improve seal quality; 2. Boost productivity; and 3. Decrease per-package film costs on form fill seal machines with reciprocating sealing jaws. Read more
