Product Presentation and Package Formation on Horizontal Flow Wrappers
The ultimate quality of the packages produced on horizontal flow wrappers requires a complex series of events to form and fill each package and move it through the packaging process. In the following post and “Tech Bites” video we explore the many steps that occur before and after packages are cut and sealed—from the product feed and film unwind through to the discharge belt—that must be fine-tuned to optimize seal integrity, package appearance, and productivity.

Product Flow Issues on Vertical Baggers
Refinements and Forming Set Designs that Boost Productivity and Package Quality
Optimizing packaging performance requires fine-tuning of the entire product flow process—from the way product is distributed into the measuring system through to the filled, sealed, and cut bag or pouch.
Symptoms of product flow issues on vertical baggers include downtime from product blockages and poor end seals and cutting problems due to product contamination of the sealing jaws and knife. Considered in isolation, as one-time incidents, each problem may only cause a relatively short period of downtime and a small amount of product and film waste. But when the cumulative impact of product flow issues is considered over time, the costs can mount. Read more
Solving Cutting Problems on Flow Wrappers During Production
When cutting problems occur on horizontal flow wrappers during a production run, what are the best procedures to get packaging lines up and running again and to keep them running? Minimizing downtime, producing consistent quality packages, and managing costs require a balanced approach that includes:
- Knowing which “quick-fix” adjustments will get knives cutting without causing additional problems and downtime. (Faster and easier is not always the best solution.)
- Broad-based, P3 Solutions that consider the entire packaging process to:
-
• Understand how each adjustment affects the whole system.
• Eliminate procedures that don’t work.
• Diagnose and correct the ultimate causes of problems. (Many issues stem from a combination of factors.)
• Implement solutions that help prevent cutting problems from occurring in the first place and help you Pursue Zero.
Sealing Over Extra Layers of Film at the End Seal (part 4 of 4): Optimizing Crimper & Sealing Jaw Design
NeedThere is no one-size-fits-all solution for the design of crimpers and sealing jaws on horizontal flow wrappers and vertical baggers; they should be specified according to the packaging film, products, and conditions of your packaging operation.
This post, the last in our four-part series, reviews design options for crimpers and jaws. The optimal combination of serration patterns, materials, and special features can dramatically improve seal quality and productivity when sealing across extra film layers at the end seal. Read more
Troubleshooting Extra Layers of Film at the End Seal (part 3 of 4): Optimizing Set-Up & Adjustment of Crimpers, Sealing Jaws, & Knives
The first two parts of this series explored the potential problems created by end seal wrinkles and creases and ways to eliminate or reduce them on horizontal flow wrappers (Part 1) and vertical baggers (Part 2). In some situations wrinkles or creases are unavoidable, and, even without those issues, most packages have the inevitable transition between multiple film layers created by either a fin or a lap seal. This can make it more difficult to achieve quality seals, and attempts to do so can lead to additional issues:
• Excess pressure can easily crush or split the end seal.
• Overheating distorts the seal and can cause poor hot tack, where the film springs back open, or “moons,” before the seal can set.
The operating window for creating quality seals can be elusive, resulting in packages that leak or are distorted and either fail to protect the product or have little appeal to consumers.
This post reviews some of the detailed solutions in Greener Corporation’s Knowledge Center that will help you seal over extra layers of film at the end seal by refining the set-up and adjustment of crimpers, sealing jaws, and knives.
