Common Problems and Solutions, Part 1
Knife and Anvil Set-Up on Horizontal Flow Wrappers

In this article we discuss a series of cutting problems commonly experienced when setting up and running horizontal flow wrappers. Each problem is followed by several possible solutions. In every case we assume that the knife and anvil being used are of good quality and, as such, the solutions deal primarily with the process of set-up and adjustment.

Cost Saving Crimper and Knife Designs

The desire for improved performance and the need for cost savings often go hand in hand, and effective part design can help to satisfy both requirements. This is especially true with crimpers and knives for form, fill and seal machinery because of their critical role in the packaging operation. Giving some thought to a few possible design variations before purchasing can result in a positive impact on the bottom line.

Basic Sealing Theory for OPP Films

This article covers the basic theory of making a good seal with oriented polypropylene (OPP) based films on horizontal flow wrappers and vertical baggers. The relationships between the three factors of the sealing equation (heat, time and pressure) are analyzed and explained in order to provide a basis for real-world application and problem solving.
