Tray sealing machines are specialized equipment used to seal trays containing food, pharmaceutical products, or other items. These machines apply heat, pressure, or a combination of both to seal a plastic film or lid onto a tray, creating an airtight or vacuum-sealed package. The sealing process helps extend the shelf life of the product, ensures hygiene, and preserves freshness. https://www.databridgemarketresearch.com/reports/global-tray-sealing-machines-market
