A recently granted patent (Publication Number: US11884023B2) discloses an apparatus designed for the quality assessment of the sealing section of a package used for food products. The apparatus includes a sample holder, a magnification device, an illumination device, a camera holder, and polarizing filters. The sample holder is transparent, allowing light from the illumination device to reach the magnification device through it. A camera is fixed on the camera holder to capture images of the sealing section. Additionally, a stepping motor is included to move the sample holder in relation to the camera holder, enabling the capture of a series of images that can be stitched together by a computer for analysis.

Furthermore, the apparatus features a light controlling device that can be set in a diffusor light position or a high contrast position. The apparatus is specifically designed for packages with a robustness layer and a plastic layer, where the sealing section is formed by melting the plastic layers of the first and second sections to adhere to each other. The use of polarizing filters, a stepping motor for image capture, and computer stitching of images into one complete image enhance the accuracy and efficiency of the quality assessment process for the sealing section of food product packages. This innovative apparatus aims to improve the inspection and evaluation of package seals, ensuring the integrity and safety of the enclosed food products.
