A single-chamber vacuum sealer (also called a single-cavity vacuum packaging machine) works by placing the entire product
bag inside one enclosed chamber. The lid closes, creating an airtight space. The vacuum pump then evacuates air from the
entire chamber \u2014 including the inside of the bag \u2014 and the built-in sealing bar heat-seals the bag mouth before atmosphere is
re-admitted.
How the Cycle Works (Step by Step):<\/p>\n\n\n\n

    \n
  1. Open lid \u2192 place product bag inside chamber<\/li>\n\n\n\n
  2. Position bag opening over the sealing bar<\/li>\n\n\n\n
  3. Close and latch lid<\/li>\n\n\n\n
  4. Pump evacuates chamber + bag simultaneously<\/li>\n\n\n\n
  5. Sealing bar heats and seals the bag mouth<\/li>\n\n\n\n
  6. Atmosphere re-enters chamber \u2192 lid can be opened<\/li>\n\n\n\n
  7. Remove sealed product \u2192 repeat
    Cycle Time: Typically 15\u201335 seconds per bag, depending on product volume and target vacuum level<\/li>\n<\/ol>\n\n\n\n
    \"\"<\/figure>\n\n\n\n

    Limitations:
    One bag per cycle \u2014 output is sequential, not parallel
    Chamber size limits maximum bag\/product dimensions
    Not suitable for very large or irregularly shaped products
    YGPACK Single-Chamber Range: Available in chamber sizes from 320\u00d7400mm to 500\u00d7600mm, with vacuum levels up to -99
    kPa and optional gas-flush (MAP) capability for modified atmosphere packaging<\/p>\n\n\n\n
