An adjustable sealer seals a long run of cartons that are the same height and width by means of manual adjustments. A random case sealer will adjust itself to the height and width of individual boxes as they arrive.

Many times, top and bottom belt case sealers are the best drive system configuration and are highly recommended for most carton-sealing applications. A four-belt system will securely drive the carton through the case sealer without skewing it or tipping it and tape is securely applied down the center seam. For example, your operation will keep running smoothly when a tall but not very long box is held by the top and bottom belts so the carton doesn’t tip as it’s taped.

Though side belt case sealers can be used for all size boxes, they’re especially useful for taping narrow-width boxes. You’ll want to make certain that the sided belts are spring-loaded, which will allow a little give when there is a slight variance in box width, such as with overstuffed cartons.

There are only two drive belts at the bottom of a bottom belt drive case sealer. This requires a little more weight in the box in order to have stable conveyance through the case sealer. Big benefits of bottom belt machines having only two belts are lower cost and they can be a great place to start improving productivity.

Occasionally you’ll have box sizes which are outside of the typical operating range of a case sealer because they’re too short or too large. 3M case sealers are able to be customized to satisfy your unique box requirements. Sometimes this may simply be an extension of the existing columns. In other situations, a custom sealer can be engineered by Korpack from the ground up using standard components.

This is going to depend on how you’re currently packaging your product, but in 90% of cases it will reduce your costs. Case sealers can replace hand taping and tape your boxes for shipment. By shifting to a flap-folding machine you’ll reduce costs by removing the need for an operator needed to fold the top flaps and present the box to the case sealer. You can further reduce costs and increase productivity through the use of a case sealer to pre-form cartons. A Korpack equipment specialist can best recommend a solution after visiting your site and discussing your needs.
