Producing Quality Packages on Vertical F/F/S Baggers- The Basics
This technical paper discusses the key basic principles of bag forming and sealing on vertical form/fill/seal packaging machines. Discussion of the design, function and adjustment of forming sets and sealing jaws is organized sequentially, following the film from the roll as it is formed into a tube, back sealed, filled with product and end-sealed. | 202 KB |
Basic Sealing Theory
This paper covers the basic theory of making a good seal with oriented polypropylene (OPP) based packaging 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. | 115 KB |
Crimper and Knife Set-Up Tips
While there is no single correct way to set up sealing crimpers and knives on horizontal form/fill/seal flow wrappers, there are some things that can be done to make the task easier. Following are two dozen "tricks of the trade" which you may find helpful. | 60 KB |
Common Problems and Solutions - Part 1
In this article we discuss some of the more common cutting problems that occur on horizontal flow wrapping machinery. Each problem is followed by several possible solutions, beginning with the simpler or more straightforward options before moving on to more complex possibilities. | 24 KB |
Common Problems and Solutions - Part 2
In this article we continue our discussion of common problems that occur on horizontal flow wrapping machinery, focusing this time on the crimpers and the sealing function. | 35 KB |
The Problem Diagnosis Process
Problems happen. This is an unfortunate reality, and packaging lines are certainly no exception. In previous White Papers we have dealt with specific problem identification and solution options for many common issues on horizontal flow wrappers and vertical baggers. In this paper we take a step back and examine the problem dignosis process itself. We explore steps that will help to uncover relevant information, identify goals, avoid inaccurate conclusions, and, ultimately, choose the proper corrective action. | 103 KB |
Cutting Edge Designs for Horizontal Flow Wrapper Knives
This paper explains the variety of cutting edge styles available for horizontal flow wrapper knives. The differences between the styles relative to both set-up and function are discussed along with the implications of the resulting cut on the package. | 83 KB |
