What is a case sealer?

A case sealer is a packaging machine designed to close and seal corrugated carton boxes efficiently. It ensures consistent sealing, reduces manual labour, and improves overall productivity in packaging operations.

Types of Case Sealer

Semi-Automatic Case Sealer

A semi-automatic case sealer requires some operator involvement, such as placing and aligning the carton before sealing. Once positioned, the machine automatically applies tape or glue to close the flaps. This type of sealer is ideal for businesses that handle moderate volumes of packaging, where flexibility and affordability are essential. Discover more of our solutions on our Home page.

Automatic Case Sealer

An automatic case sealer minimises manual handling by automating both carton feeding and sealing. It is well-suited for high-volume packaging operations, ensuring faster output and consistent sealing across all boxes. Automatic sealers help businesses improve efficiency while reducing labour requirements. You can also explore our Company Profile to learn more about our expertise in packaging solutions.

Benefits of Using a LANTECH Case Sealer Machine

– Controlled entry of cases into a machine which keeps cases square

– Auto adjustment for case width variations by adjustable infeed guides that introduce the case into spring-loaded side belts which move in/out to compensate for minor differences in case widths

– Smooth case transit through the sealing cycle via rollers

– Ensures the proper folding of the flaps. Folds the flap perpendicular to the case walls so the top side flaps will be horizontal when they are closed

– Easy tape change and accessibility

– Precision glue patterns

– Safe operation

– Fast and easy changeover of carton boxes

    Frequently Asked Questions

    What is the difference between a semi-automatic and a fully automatic case sealer?

    A semi-automatic case sealer requires an operator to place and align cartons before sealing, while a fully automatic case sealer handles both feeding and sealing without manual input. This distinction often depends on the production volume and the level of automation required by your packaging line.

    You can learn more about our full range of solutions on our Home page.

    The choice depends on factors such as carton size, sealing method, production speed, and budget. Semi-automatic models are suitable for moderate throughput, while automatic models are designed for high-volume operations.
