Cheese packed with care – Hazeleger monitors packaging quality using SealScope™


Hazeleger Kaas is an independent packaging company of Dutch cheese specialty products and a service provider for renowned cheese brands. One of the main activities is to slice cheese and package it in horizontal flows packs under modified atmosphere.

When introducing a new type of package, it is necessary to master the quality level of outgoing products at the desired production volumes in the shortest time possible. As Hazeleger launched a new re-sealable package for sliced cheese, they searched for the latest technologies in seal inspection to monitor and optimize the new packaging line. Possible causes of defect packages are product in seal or wrinkles. To avoid product in seal, the positioning of the trays, the stacking of cheese on these trays and the relative positioning within the packaging film turned out to be crucial. Also wrinkles in the fold-over need to be avoided to warrant seal integrity, especially for gas flushed products.

In a first step of the process optimization, the number of defective packages needed to be reduced by analyzing the sealing process. This was a crucial step as the new packaging line still needed finetuning. As SealScope™ instantly and objectively measures the seal quality of every package, it automatically quantifies whether adjusting the packaging line parameters improves the process.

SealScope™ is detecting and rejecting residual packaging defects, optimizing the outgoing packaging quality. The patented SealScope™ technology automatically builds an adaptive reference model of good seals and compares every sealed product with this base line.

The benefits of SealScope™ at Hazeleger Kaas are measurable in both increased output and better package quality, creating a sustainable competitive advantage.
“We made a huge step forward in mastering our packaging line to guarantee our high outgoing quality”, says Wim van Rijn, owner of Hazeleger Kaas. “We fully trust on the SealScope™ application for our packaging quality.”
