slovenia Small Bag Vacuum Heat Sealer
winnie@mypackmachinery.com
Product Description
This integrated vacuum-pumping and heat-sealing machine is specifically designed for 25 kg small bags, enabling internal vacuum degassing and bag-mouth heat sealing to effectively prevent moisture absorption, oxidation, and powder reversion. It is available in three configurations: external-pump type, box-type with automatic conveying, and box-type with manual door opening, catering to diverse small-bag packaging needs across varying levels of automation and production environments. The entire system features dual-channel, double-sided heating with adjustable temperature and time settings; thermocouples ensure precise temperature control and real-time display on the touch screen. The sealing area is equipped with a replaceable high-temperature adhesive pad for easy maintenance. A dust-proof design is incorporated for lithium-battery applications, while food- and pharmaceutical-grade models meet stringent hygiene requirements. The machine can be seamlessly integrated with upstream packaging equipment and checkweighers.
Product Categories
- External-extraction heat sealer: features constant-temperature heating and a duckbill-style vacuum extraction function, offering flexible operation and a compact footprint, making it ideal for vacuum sealing small bags in small to medium batch sizes and with multiple specifications.
- Small-bag carton heat-sealing machine (with automatic conveyor): features an integrated sealed chamber and an automated conveyor line, enabling full-process automation, excellent vacuuming performance, precise control of headspace gas content, and ideal suitability for high-volume, highly automated small-bag packaging.
- Small-bag, box-type heat sealer (manual door opening): features a fully sealed chamber; bag placement and removal are manually assisted; offers high vacuum-pumping accuracy and excellent cost-effectiveness; ideal for high-precision sealing of small bags in small to medium batch production.
