Product spoilage caused by improperly closed packages cause serious problems for manufacturers, particularly those who deal in food. The cost of product returns and waste caused by contaminated or spoiled products can be significant. Our vision systems perform seal inspection on trays, packages and container closures to ensure products remain free from outside contamination.
Seal Check Vision Inspection Systems
Check for contaminants in seals, and integrity of container closures
Detect Improperly Sealed Packages
Verify Sealing Surfaces Prior to Packaging
Detecting an improperly sealed container is important, but preventing an improperly sealed container from being created in the first place is even more useful. Our systems identify uneven or otherwise damaged sealing surfaces on product packaging and remove them from the production line, preventing them from being filled.

Verify Tamper Band Presence and Integrity
The presence of a tamper band on beverages, pharmaceuticals, and even cosmetics assure consumers that the product has not been altered in any way once it leaves the production facility. Our systems both verify the presence of a tamper band and inspect the band to see whether or not it is properly attached to the package cap.
Smart Cameras and PC Based Vision Systems
We offer both smart cameras and PC based vision inspection systems to provide a solution that meets your needs. Additional connectivity options are also available to integrate our systems with your production equipment.

FAQs
What defects are common in packaging seals?
Common seal defects include holes in the seal itself, product caught in the seal, and (more simply) improperly-applied seals. Another common defect is marring or unevenness in the sealing surface itself, which prevents a good seal.
How does seal inspection work?
Depending on a few factors – the seal type, the location, and the material the seal is made from – it is often enough for a camera to look for the presence of the seal material and identify any unusual markings. For clear seals, UV ink is often used to mark the seals, which cameras are able to spot by using specialized lights.
How reliably can a vision system spot flaws in a package seal?
Completely clear seals are difficult to inspect, as the system may not be able to reliably spot holes or gaps. Foil or colored seals are far easier to spot flaws in, although depending on how reflective the surface is it may be necessary to utilize specialized lighting in order to provide a clear image.
