TriVision Inspection types

Seal inspection

Ensure food product quality, appearance and optimal shelf life with seal inspection of food packaging.

Seal validation for ensured product quality and optimal shelf life

Package sealing is a crucial step in the packaging process of food products in sealed packages. An intact package seal keeps the food product in a closed environment with the best conditions for ensuring optimal shelf life and product quality in terms of appearance, taste and nutrients.

TriVision’s seal inspection is developed to check and validate the seal of skin pack and modified atmosphere packaging, i.e. thermoformed packaging and tray sealed packaging, which isolates gas mixtures with the food product to preserve product freshness and extend shelf life.

With unique, proven setups of camera and light setup above and below conveyor belt level and advanced image processing software, our systems can validate sealed packages' seal integrity.

Even small elements can compromise the integrity of the seal reducing the protective functionality of the package and lead to spoilage of the food product.

In addition, studies have shown that consumers naturally deselect food items that have less than optimal appearance leading to lost sales and increased waste.
