SW-ZK Series: Rotary Vacuum Sealing Machine
The SW-ZK series is built on the same 8-station rotary platform as the ShengWei premade bag machine family, with one critical addition: an integrated vacuum pump that extracts air from each pouch before the sealing jaws close. Removing oxygen from the package inhibits bacterial growth, prevents oxidation, and dramatically extends the shelf life of perishable products — meat, seafood, cheese, and frozen goods stay fresh substantially longer than standard sealed pouches.
Product is fed into the open pouches from an external hopper or feeder (not included; matched to your product type). The PLC + HMI touch screen controls vacuum depth, sealing temperature, and cycle timing independently. All product-contact surfaces are SUS304 stainless steel. Two models cover bag widths from 80 mm to 160 mm — pick by your largest pouch format. Both handle stand-up and flat pouches.

The SW-ZK series is designed for small-portion vacuum packaging (10–50 g). For larger bag sizes or heavier fills, see the SW-D series (granules) or SW-Y series (liquids) with optional vacuum extraction add-on.
Supported Pouch Types for Vacuum Packaging
The SW-ZK series handles the two most common premade pouch formats for vacuum-sealed products. Both work with standard vacuum-grade laminated film. Switching between types is done through the HMI panel — no tooling changes.
Stand-Up Pouch — shelf display for vacuum-sealed snacks and ready-to-eat products
Flat / 3-Side Seal Pouch — conforms tightly around product after vacuum extraction
Vacuum-Grade Film — multi-layer laminated film with high oxygen barrier for maximum shelf life
Stand-Up Pouch
3-Side Seal
4-Side Seal
Fin Seal
Film requirement: Vacuum packaging requires multi-layer laminated film with high oxygen barrier (e.g., PA/PE, PET/AL/PE). Send us your bag sample or film specification for compatibility confirmation.
How the 8-Station Vacuum Packing Cycle Works
All stations run simultaneously — while one pouch is being vacuum-sealed, others are being loaded, filled, and discharged in parallel.
1. Bag Feeding
2. Date Coding
3. Bag Opening
4. Filling
5. Taking Over
6. Vacuum & Seal
7. Output
01
Load & Open
Suction cups pick premade pouches from the bag magazine onto rotary gripper clamps. A second set of suction cups separates the panels; an air jet inflates the bag fully open. Sensors skip any failed opens automatically to prevent downtime.
02
Fill
Product drops into the open pouch from an external hopper or feeding system (vibrating feeder for granules, belt conveyor for irregular items like meat strips). The feeding system is matched to your product type and quoted separately. Fill weight range is 10–50 g per pouch.
03
Vacuum & Seal
The integrated vacuum pump extracts air from inside the pouch down to −0.1 MPa. Once the target vacuum depth is reached, heated sealing jaws close under controlled pressure. Temperature, dwell time, and vacuum depth are independently adjustable per recipe via the HMI panel. Cooling plates solidify the seal immediately to prevent deformation.
04
Code & Discharge
Optional date coder prints batch info and expiry date on the finished pouch. Gripper clamps release onto the outfeed conveyor. A reject mechanism removes underweight or failed-seal bags before they reach the packing station.

SW-ZK series vacuum packing machine — compact rotary platform with integrated vacuum pump
Complete Vacuum Packaging Line
The SW-ZK series is the core of a vacuum packaging line. ShengWei helps you select and integrate the right feeding system, conveyor, and downstream equipment for your specific product. Send us your product details and target output for a line proposal.
Vacuum Packing Machine
Core of the line — 8-station rotary carousel with integrated vacuum pump. Loads, opens, fills, vacuums, seals, and discharges pouches in a continuous cycle.
Rotary Platform
Same proven 8-station platform used across the entire ShengWei premade bag machine family. Gripper clamps, suction cups, and sealing jaws are common spare parts.
Optional Add-Ons & Feeding Systems
The vacuum machine does not include a product feeding system — this is quoted separately based on your product type. Common configurations:
- Vibrating feeder for small granular products (nuts, dried fruit, tea)
- Belt conveyor feeder for irregular items (meat strips, seafood, cheese slices)
- Bucket elevator for bulk product transfer from upstream processing
- Date coder (inkjet or thermal ribbon) for batch/expiry printing
- Checkweigher for inline weight verification
- Metal detector for contaminant screening
- Outfeed conveyor to downstream cartoning or case packing

Vacuum vs Standard Sealing: Which Do You Need?
Not every product needs vacuum packaging. The right choice depends on your product's sensitivity to oxygen, your target shelf life, and your bag size.
Choose Vacuum Sealing (SW-ZK) When:
- Your product is perishable and degrades rapidly when exposed to oxygen (meat, seafood, cheese, cooked food)
- You need to extend shelf life substantially without chemical preservatives
- Your bag size is small — under 160 mm wide and under 50 g fill weight
- Retail presentation requires a tight, wrinkle-free vacuum seal around the product
Choose Standard Sealing When:
- Your product is shelf-stable (dry snacks, candy, nuts, coffee) and does not require air removal
- Your bags are larger than 160 mm wide or fills exceed 50 g
- You need nitrogen flushing instead of vacuum (e.g., chips that would crush under vacuum)
- Higher speed (50+ bags/min at large bag sizes) is the priority over vacuum depth
When This Machine Is Not the Right Fit
The SW-ZK series is designed for small-portion vacuum packaging only (bag width ≤ 160 mm, fill weight ≤ 50 g). For larger bags with vacuum, the SW-D series and SW-Y series offer optional vacuum extraction as an add-on for bags up to 320 mm wide. For liquid products that need vacuum, use the SW-Y series with a metering pump and vacuum option. For spout pouches, see the SW-CCS6 spout pouch machine.

Tested Before Shipment — How We Prove the SW-ZK Series
72-Hour Run Test on Your Bags
Every SW-130ZK and SW-160ZK goes through a structured Factory Acceptance Test before it ships: a 72-hour continuous run with actual packaging film and product material, with speed, seal quality, weight accuracy, and rejection rate all logged. For a vacuum premade-bag machine that means verifying gripper transfer and bag opening across your bag sizes (80–160 mm bag widths), seal quality on vacuum-grade laminate, stable output across the 20–70 bags/min working range — and, for the vacuum stage, chamber-cycle and vacuum consistency checks on your bags and product.
Approve Before We Crate
Before crating, our QC team sends you the FAT report, a test video of your machine running, and photos for approval. If your order requires it, we coordinate SGS, Bureau Veritas, or TÜV pre-shipment inspection and provide full access to the machine and test records. See how the 4-person QC team works at our Factory & Quality Center.
