Bag Sealers
Close prefilled heat-sealable bags. Match seal length, bag thickness and loading orientation.
Explore machines →Sealing Machines
Explore ZONESUN sealing machines for bags, cups, trays, tubes, cans, bottles and cartons. Start with your package format and material, then compare sealing methods, operating modes and required output. Tooling and line-integration options vary by model.
Find Your Sealing Method
Start with the package you need to close. Each category includes model-specific configurations.
Cup & Tray Sealers
Match the container rim, lid film and tooling. Check whether filling is included.
Explore machines →Tube Sealers
Choose tube-tail sealing for compatible plastic or laminated tubes; confirm material and diameter.
Explore machines →Can Seamers
Match the can body and lid specification. Confirm chuck, rollers and seam testing requirements.
Explore machines →Aluminum Foil Sealers
Choose induction or contact heat sealing to suit the container and compatible foil liner.
Explore machines →Vacuum Sealers
Compare chamber size, pouch dimensions and cycle output. Confirm configuration for liquids or powders.
Explore machines →Carton Sealers
Close loaded cartons using tape or glue. Confirm box sizes and flap-closing requirements.
Explore machines →Need Filling Too?
For dosing plus sealing, compare integrated equipment separately from standalone sealers.
Explore filling & sealing →Four Checks Before Choosing
Send these details with your enquiry to narrow down suitable models.
Package & material
Share package samples, dimensions and seal-layer or liner specifications. Compatibility depends on the complete material structure.
Seal & tooling
Confirm seal width, rim shape, tube diameter or can-and-lid design. Ask which change parts are needed for each size.
Output & handling
State required finished packs per minute, loading method and product condition. Rated speed may differ from usable line output.
Utilities & testing
Confirm voltage, air supply, footprint and cleaning needs. Request a sample trial and agree acceptance checks for your package.
Connect the Packaging Steps
The sequence depends on your package. Confirm conveyor height, spacing and controls before combining machines.
Prepare & fill
For prefilled bags, tubes and containers, match dosing output to the sealing cycle.
Filling machinesClose & seal
Bottle induction sealing commonly follows capping; cans need compatible seaming tooling. Choose the route for your closure.
Capping machinesTransfer & finish
Plan transfer, accumulation and labeling around finished package stability and line speed.
Conveyors & turntablesSealing Machine FAQ
Which sealing machine is right for my packaging?
Start with package format and the surfaces being joined. Heat sealing needs compatible seal layers; induction sealing needs a compatible foil liner and container; can seaming uses matched can-and-lid tooling. Send samples before confirming a model.
Does a sealing machine also fill the product?
Not necessarily. Many models close prefilled packages. Filling-and-sealing systems add dosing equipment; optional modules and the supplied configuration must be confirmed for each model.
Can one machine handle different sizes?
Some models offer adjustments or interchangeable tooling. The supported size range, change parts and changeover procedure vary by model; confirm all intended package sizes before ordering.
What is the difference between heat sealing and vacuum sealing?
Heat sealing joins compatible seal layers. Vacuum equipment removes air before closing the package, often with a heat seal. Chamber size, product behavior and pouch material determine the suitable configuration.
Can I connect the sealer to an existing line?
Check package transport, machine height, spacing, cycle speed, utilities and control signals. Some models operate independently, while others support conveyor or modular integration.
