Are you planning to test or convert to sustainable packaging films on your flow wrappers or vertical form-fill-seal baggers? Your current machine set-up and components may not provide quality results with these paper-based, recyclable, or compostable materials.
This Greener Tech Bite outlines steps in your packaging process that you should evaluate and adjust before running these new films. You’ll find links to resources for:
• Machine Set-Up
• Sealing Jaw & Former Design
• Standard Operating Procedures
Sealing jaw carbon impressions provide a vital roadmap for diagnosing and troubleshooting problems on flow wrappers and vertical baggers. This Greener Tech Bite demonstrates how multiple issues can be revealed by a single impression.
Changes on horizontal flow wrappers occur regularly—during sanitation, product changeovers, part installations and adjustments, maintenance, and from wear and tear. These changes can impact the success of your next production run, yet they often go unnoticed.
This Greener Tech Bite presents our quick, Preventative Maintenance Checklist. By investing five or ten minutes to inspect these four areas before starting production, you will be up and running more quickly and avoid hours of downtime. Read more
One of Greener’s Technical Salespeople discovered that knife purchases by their customer had grown by 35% over the past year, at an additional cost of nearly $10,000. It seemed unlikely that additional production had accounted for all of this increase, which indicated to him that the customer could be experiencing problems on their horizontal flow wrappers.
Do you run different makes or models of flow wrappers or vertical form-fill-seal baggers?
If you do, you probably use a variety of knife and sealing jaw styles that you need to keep in stock. With different knife or sealing jaw designs, the seal quality and appearance of your packages may vary, depending on which machine, line, or facility produced them. Read more

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:
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.
