Inspecting heat sealed packages
Seal inspection through a printed film
Airtight packages preserve the product’s freshness, improve quality and prevent leaks. It is essential to ensure that the package is reliably sealed, and this sets requirements for seal inspection process.
Good seals can only be made on clean material: any contamination between the seal and the package is no longer airtight. As a result, air and contaminants such as molds, fungus or bacteria can enter the package and ruin the product well before the expiration date.
