Handheld, Tabletop & Pneumatic
For individual bags and batch work. Match sealing-bar length, pressure and heating mode to the bag opening, thickness and sealable layer.
FLEXIBLE PACKAGING
Bag Sealing Machines
Heat seal, continuously close or vacuum seal compatible plastic bags, foil laminate pouches and coated kraft paper bags. Choose by bag material, filled weight and sealing workflow.
BAG CLOSING
Select a Sealer Around Your Bag
Start with the material structure and how the filled bag needs to be handled.
Bag sealers close flexible packaging after loading. This collection covers compact heat sealers, continuous sealing equipment and vacuum bag systems, with specialist options for courier bags and compressed textiles. The suitable machine depends on the sealable layer, bag opening, filled weight and working pattern.
MATERIAL CHECKPlastic, foil laminate and kraft paper bags do not all use the same sealing settings.
Confirm the heat-sealable layer and test the complete bag, especially folded edges and thicker laminates. Temperature, pressure and dwell time must suit the material.
EQUIPMENT PATHS
Choose by the Sealing Task
Three practical routes for closing compatible flexible bags.
Band & Roller Sealers
For repeated bag closing with controlled feed. Select horizontal or vertical handling to suit the contents; coding and marking options depend on the model.
Air Removal & Bulky Bags
For compatible vacuum bags or textile compression packaging. Choose chamber, external-nozzle or automated vacuum equipment according to bag size and product handling.
PROJECT REQUIREMENTS

COMMON QUESTIONS
Bag Sealing Machine FAQs
Material compatibility, handling and options to check before ordering.
Can these machines seal kraft paper and aluminum foil bags?
Suitable models can seal laminated or coated bags with a compatible heat-sealable layer. Uncoated kraft paper and plain aluminum foil are not equivalent to heat-sealable bags. Check the actual layer structure and test samples.
Should I choose a horizontal or vertical band sealer?
Choose based on how the filled bag must be supported. Vertical arrangements can keep contents upright; horizontal arrangements suit bags that can lie flat. Confirm sealing height and conveyor load for the selected machine.
Does every bag sealer include vacuum or gas flushing?
No. Standard heat sealers close the bag without extracting air. Vacuum and gas flushing require a model designed for those functions, suitable bags and any specified gas supply.
Can a bag sealer also print dates or batch numbers?
Selected models include embossing, solid-ink coding, inkjet printing or laser marking. The available characters, print area and bag compatibility vary by model.
Is a bag sealer the same as a form-fill-seal machine?
A bag sealer primarily closes a bag. A form-fill-seal system makes packages from film and doses the contents before closing them. Automated vacuum pouch systems may combine bag handling and optional filling with vacuum sealing.
What should I send before choosing a machine?
Send bag samples or layer specifications, dimensions, gusset details, filled weight, product photos and target output. These help check the sealing method and required machine configuration.
