Carbon impression are most often used to guide the setup of sealing jaws and to solve problems on flow wrappers and vertical form fill seal baggers.
But Carbon impressions should also be taken before each new production run and when variables such as product size or packaging materials change. These extra impressions will indicate ongoing adjustments and preventative maintenance that prevent package quality problems and lost production time. Read more
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
This Greener Tech Bite reviews machine adjustments and sealing jaw designs that provide the pressure and heat* required for quality seals. You can consult additional, detailed posts and videos on each topic by clicking the red links or the corresponding images.
Quality seals on flow wrappers & vertical baggers require a combination of time, pressure, and heat, if utilized, that seals across varying thicknesses created by the fin or lap seal, gussets, or other pleats and wrinkles. Read more
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
• Training
In this Greener Tech Bite we analyze six sealing jaw carbon impressions and explain how each was used to troubleshoot problems on flow wrappers or vertical form fill seal baggers. Read more
This Greener Tech Bite, with the help of our partner Kenray Forming, explores six key design and set-up principles to help you identify the source of forming and sealing problems and develop solutions for quality packages. Read more
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
