THERMOSEAL INSPECTOR
Machine vision equipment for packaging inspection



Thermoseal Inspector analyses any type of packaged product, with application in the food or pharmaceutical industry.
It is a quality inspection equipment designed to verify the integrity of the thermosealing area. Depending on its configuration, it is equally capable of analysing deviations in product quality inside the package, or also detecting contamination and foreign bodies. It works with any type of container in which its airtightness is achieved by means of two heat-sealed films, in order to prevent the deterioration of the product.
The equipment allows quality problems to be detected both in the package itself and in the packaged product. It incorporates a text and code reading function, allowing complete traceability of the inspected packages.
Thermoseal Inspector is custom configured for each application and for each client. Depending on the inspection needs, it can incorporate artificial vision technologies by SWIR hyperspectral image, by NIR image or by high resolution RGB image within the visible light spectrum.
In addition, the equipment shows real time indicators of quality and productivity, sending reports and quality alarms.
What are the advantages?
Inspection of the welding area and the inside of the package within the visible range, NIR and SWIR
Inspection of the top and bottom of the packages
Suitable for a large number of products and packaging
Modular equipment adapted to product and customer needs
Compatible with different product rejection systems
Options
Thermoseal Inspector offers different options depending on the type of container and the defects to be detected. The Standard model, designed for simpler containers and defects, and the Advanced model for the inspection of more complex containers. In addition, both include the option of label inspection.
THERMOSEAL INSPECTOR STANDARD

This equipment option inspects packages inspection using RGB vision technology, with high performance in terms of speed and detection accuracy. It can include up to 3 cameras and has 2 inspection gaps.
THERMOSEAL INSPECTOR ADVANCED

This equipment option inspects packages using hyperspectral vision technology, identifying its chemical composition and assigning different shades of colour. It can include up to 5 cameras and has 3 inspection gaps.
Functionalities
- Detection of contamination or defects in the welding area of the heat seal
Quality inspection of the packaged product: contamination, quality parameters, incorrectly positioned product, etc.
Reading of texts and bar codes on the package
- Generation of quality indicators for inspected production
Production traceability, through images and data
Connection of the equipment in remote for visualization of data in real time
Easy connection with rejection modules of different technologies
Simple and ergonomic interface, with the possibility of adapting to customer needs
Specifications
THERMOSEAL INSPECTOR
Depending on the inspection requirements of the containers to be analysed, the Thermoseal Inspector equipment has image processing systems with hyperspectral technology in the SWIR and NIR ranges. This represents a technological and performance leap compared to conventional inspection systems.
Hyperspectral technology makes it possible to segment the chemical footprint of the components it inspects, easily differentiating defects or contamination that at first sight could be mistaken for having similar colour shades. In the Thermoseal Inspector equipment, it is applied to give greater power to the inspection of the heat seal, and for the detection of contamination or quality deviations in the packaged product.
The equipment is capable of inspecting the top and bottom of these packages, obtaining and processing images of both the product and the package itself, even in the case that these films are printed with inks that are opaque to visible light.
Its main applications are aimed at:
- Detection of (complex) contamination in the heat-sealing area: melted fat residues, interleaver invasion, invasion by sealing film fragments, etc.
- Presence of foreign bodies and deviations in the quality of the packaged product
- Detection of incorrectly positioned product in containers with opaque inks
Depending on the inspection requirements of the containers to be analysed, the Thermoseal Inspector equipment has high-resolution RGB artificial vision systems, within the visible spectrum.
INSPECTRA’s processing algorithms for RGB vision technology have been refined and are the result of years of development, achieving high performance in terms of speed and detection precision, which allows for high efficiency in the detection of contamination and quality deviations.
Its main applications are aimed at:
- Contamination detection (simple) in the thermosealing area
- Presence of foreign bodies and deviations in the quality of the packaged product
- Detection of incorrectly positioned product in containers with transparent inks
- Top and bottom print reading on packaging: text and barcodes
- Detection of the presence or absence of labels
The equipment can include Deep Learning systems in all its modalities (Standard and Advanced). This technology consists of an automatic hierarchical or structured algorithm that emulates human learning to obtain certain knowledge. The system itself is capable of learning by itself through a previous “training” phase, without the need for additional programming.
Image classification based on deep learning enables product or defect classification tasks to be carried out using machine vision techniques.
By means of semantic segmentation, trained defect classes can be located with pixel precision. This allows inspection tasks to be solved, which previously could not be performed, or only with significant programming effort.
Its main applications are aimed at:
- Detection of contamination in the heat-sealing area.
- Detection of anomalies and defects in the heat-sealing area: wrinkles, roll defects…
- Presence of foreign bodies and deviations in the quality of the packaged product.
- Detection of incorrectly positioned product
