Seal inspection


In many industries the end product is packed in a sealed container to guarantee the quality and hygiene of the end product. To fulfill the specification shown on the container an airtight all-around perfect seal is needed.  The production method for these of seals is that a heated mould disperses the heat in the glue what then binds the container and the top-sheet together.

In this seal-forming process there are many variables that influence the end result, for example; mould pressure, mould temperature, in-mould time, sheet- temperature, process speed, foil type, foil thickness, glue type, positioning of foil the on the container, full glue seam, and a glue seam without contamination.

Simac has great expertise in seal inspection for a wide variety of containers and end products.
Imagine the difficulties you will meet when, the container, the glue and the top-sheet are 100% transparent and the end product has to be packed under conserving gas.

If you would like to know if your product is properly sealed, just send in your container; our engineers can easily do a feasibility study determining what is possible.
