The sandwich tray sealing machine is an automatic sealing device designed for sandwich packaging trays.
The sandwich tray sealing machine is an automatic sealing device designed for sandwich packaging trays (plastic boxes, paper boxes, etc.), mainly used for the rapid sealing process of food processing or catering chain enterprises. Its core function is to firmly combine the box cover with the edge of the box body through the hot pressing welding process to ensure sealing and product preservation.
Features
Vacuum Preservation: By extracting air from the packaging bag and sealing it after achieving a predetermined vacuum level, this removes some of the oxygen from the container, inhibiting the growth and reproduction of microorganisms and preventing oxidation of the fat in the sandwich, thereby extending its shelf life.
Tight Sealing: Utilizing high-quality heat-sealing technology, the bag seal is airtight, preventing air from re-entering while ensuring a smooth, secure seal that resists cracking. Some high-end models also feature adjustable sealing temperature and time to accommodate different packaging materials.
Easy Operation: Most sandwich vacuum sealers utilize automated designs for a simple operation process. Simply place the sandwich in the bag, insert it into the machine, and press the start button. The machine automatically completes the vacuuming and sealing process.
Some models offer Modified Atmosphere (MA) functionality: In addition to vacuum packaging, some sandwich vacuum sealers can also be filled with an inert gas such as nitrogen after vacuuming to create a modified atmosphere. This further protects the sandwich, preventing deformation during transportation and storage while preserving its original flavor and quality.
