Continuous Band Sealing Machine
Frequently Asked Questions

Should I use a vertical or a horizontal model?

Say you had a bag that contained your product, and you laid it on its side, would product flow towards the mouth of the bag? If the answer is yes, then you need a vertical band sealer. Products typically sealed with vertical machines are grains, powders, nuts and bolts, candy, bonbons, and liquids, among others. If on the other hand, your product just lay there undisturbed, then you could probably use a horizontal band sealer. Horizontal machines are typically used to seal tortillas or pastries, large computer chips, paper products, and trays, among others.


Can this machine seal foil or laminated bags?

Yes, it is designed to seal any thermoplastic material, including Polyethylene, Polypropylene, and laminations containing foils, such as those used to package coffee, or those that reduce electrostatic charge used to package electronic components.


Can the distance between of the conveyor and the seal area be adjusted?

Yes it can, to a certain degree. Check your listing for more detail, or contact us if you need further clarification. Remember that once filled, a bag may be less tall than when empty.


I need a vertical band sealer. Will my bags fit unto this machine?

Please refer to the Conveyor Height section of your machine specifications. These are the minimum and maximum distances between the top of the conveyor, where your bags sit, and the seal area. The size of your - filled - bags should lie more or less within these measurements.


Are these machines wash-down?

Absolutely not. These machines are not made to work in high humidity environments, nor in areas where explosive gases or excessive dust is present. Unless otherwise noted never wet your machines. Please contact us if you need further clarification. Read and store all machine literature thoroughly before operating.


Are there any consumables or parts we should keep in stock?

Yes, you should always keep a few sealing bands, as these have a limited life span. The machines come with a kit of spares, but keep an eye on how many you have left.
Likewise if you use your coder make sure to keep a few rolls of ink at hand.


How often should I change the sealing bands?

These machines come equipped with Teflon-infused fiberglass bands, which securely yet gently hold the bag thorough the sealing process. Factors such as the type, quality, and thickness of the material you seal, as well as the speed and the amount of time the machine is running, how the machine is operated, and how well it is maintained all take part in band life.

Here are a few tips that will extend band life:

  • Use the minimum necessary temperature to seal the bags.
  • Keep the band clear of plastic or debris by carefully applying a clean rag over it.
  • Spraying liquid silicone on the band - it acts as an additional agent against adhesion and helps dispel heat away from the fabric.
  • Allow machine to cool by turning off the heat system while keeping the conveyor/band system running for a few minutes.
  • If applicable - open the gap between bands to the maximum while maintaining optimal bag control.
