Refinements and Forming Set Designs that Boost Productivity and Package Quality

Improve Product Flow on vertical baggers_Greener corporation_Kenray Forming 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

Troubleshooting Extra Layers of Film at the End Seal (Part 2 of 4): Refining and Eliminating Wrinkles and Creases on Vertical Baggers

Varying thicknesses of film at the end seal can cause sealing problems, especially at the transition points of multiple film layers created by the fin or lap seal, gussets, wrinkles, creases, and at the corners. Applications of pressure and heat must be great enough to cause the sealant layer to flow into and seal off these voids. However, excess pressure can easily crush or split the end seal, while overheating distorts the seal and can cause poor hot tack, where the film springs back open, or “moons,” before the seal can set.

Side to Side Misalignment

Even experienced users of forming sets can, over time, become conditioned to accept the hidden costs and preventable constraints of their packaging equipment. As with all waste, however, careful diagnosis of the root causes will lead to implementation of effective solutions.

One such root cause is forming tube misalignment. This can occur if the forming set has been accidentally mishandled and damaged or if the forming set has not been properly designed and fabricated in the first place. Read more
