GKE now offers different SEAL-TEST seal indicators for continuous sealers (indicator with 173 mm width) and bar sealers (indicator with 250 mm width). These allow the testing of the seal seam quality for film-paper and Tyvek packaging. For more information, please see data sheet.
The guideline for the validation of packaging processes according to EN ISO 11607 specifies that the quality of the heat sealing seam is regularly checked with a test in everyday use.
