SW-2830A: Self-Flow Liquid VFFS for Jelly and Beverage Sticks
The SW-2830A is a purpose-built vertical form-fill-seal machine for liquid and semi-liquid products packed in stick or bar shaped sachets. Product flows from a 304 stainless steel hopper through a self-flow (gravity) feeding system into the forming tube, then the vertically-oriented film tube is sealed and cut to produce long thin stick packs. This is the standard format for drinkable jelly, stick ice pops, single-serve flavoured beverages, drinking yogurt, and similar products that set, cool, or are consumed directly from the tube.
The machine runs at 60-100 bags per minute depending on fill volume and bag size. Standard bag length is 50-200 mm, bag width is 40-150 mm, and rollstock film width is up to 280 mm. A frequency converter regulates main motor speed with smooth acceleration, and independent PID temperature control on the longitudinal and cross seal jaws keeps seal strength stable across the laminate films typically used for liquid stick packs. Total power is 1.2 kW on a 220V 50/60 Hz single-phase supply, and the machine weighs approximately 300 kg with a footprint of 1,260 x 980 x 1,940 mm.
For long-grain powder or granular products in stick-pack sachets, the SW-2830B reciprocating stick pack machine is the companion model — it uses a pneumatic reciprocating sealing jaw and serves powders such as sugar, coffee, and bean powder. For flat four-side-seal liquid sachets rather than stick format, see the SW-1528 four-side-seal liquid machine. For pillow-pouch ice pop packaging with horizontal film feeding, see the SW-100 ice pop pillow pouch machine.

The SW-2830A is a dedicated liquid stick-pack machine. For powder or granule stick packs, use the companion SW-2830B reciprocating stick pack machine. For flat four-side-seal liquid sachets, see the SW-1528 four-side-seal machine. For horizontal pillow-pouch ice pops, see the SW-100 ice pop pillow pouch machine.
Output Bag Type: Stick-Pack / Bar Sachet
The SW-2830A produces long thin stick or bar shaped sachets sealed along the back seam and across both ends. This is the standard format for drinkable jelly, stick ice pops, and single-serve liquid beverages because it is easy to tear open from the end, easy to freeze or chill in volume, and easy to merchandise in pegged retail displays or bulk tray packs.

How the Self-Flow Stick-Pack Cycle Works
The forming, filling, and sealing sequence runs continuously at 60-100 bags per minute. A frequency converter regulates main motor speed and the sealing jaws cycle at a consistent dwell time. Both liquid feeding and sealing parameters are adjusted from the touch screen.
01
Self-Flow Liquid Feeding
Liquid product is held in a 304 stainless steel hopper above the forming tube. A float or level sensor maintains the working level. Product flows by gravity through the filling pipe into the formed film tube. Fill volume is set by the cycle timing between cross seals, so dosing is repeatable as long as hopper level and product viscosity stay stable.
02
Film Forming & Back Seal
Rollstock film unwinds from the rear holder, passes the double film clamp, and wraps around the forming tube. The longitudinal (back) seal jaw closes the film into a continuous tube. Film pull is driven by a servo motor for accurate bag length, and photoelectric tracking reads the registration mark on pre-printed film so each sachet is cut in the correct position.
03
Cross Sealing & Liquid Discharge
Horizontal cross seal jaws close across the filled tube to form the end seal of the current stick and the start seal of the next. Because the feed path is vertical, liquid naturally settles toward the bottom of the bag for a full, neat stick appearance. Seal temperature, jaw pressure, and dwell time are tuned to the film laminate.
04
Cutting & Discharge
A cutter built into the cross seal jaw separates finished sticks. An easy-tear notch is stamped at the end for clean consumer opening. Sticks can discharge as individual units, as a linked chain for cold-room freezing (ice-pop applications), or onto a downstream conveyor for carton packing. An optional date printer codes production date, batch, and expiry onto each stick during the sealing cycle.

Four Core Systems That Define Stick-Pack Quality
The SW-2830A is built around four mechanical systems that together determine stick appearance, fill consistency, seal integrity, and maintenance simplicity. Understanding each helps you specify the correct options for your product before quotation.
1. Self-Flow Stainless Hopper
Product feeds the forming tube by gravity from a 304 food-grade stainless steel hopper. The wetted path has no pump seals or valve rings to maintain, which simplifies cleaning between SKUs. Optional cooling jacket, CIP rinse connection, and level sensor are available for dairy and ice-pop applications.
2. Dual-Zone Temperature Control
Two independent PID temperature controllers regulate the longitudinal and cross seal jaws separately. This matters on PET/PE and PA/PE laminates where the back seam and end seals need different temperature and dwell time for a clean, leak-free seal on liquid-filled sticks.
3. Frequency-Controlled Drive
A frequency converter regulates main motor speed with smooth acceleration and deceleration. Speed is adjustable on the HMI rotary control. Smooth starts protect film integrity when switching between SKUs with different stick lengths and fill volumes.
4. Easy-Adjust Operation
Fill volume is set by cycle timing; bag length is set by the servo film pull; seal temperature is set by the two PID controllers. All three parameters adjust from the touch screen without mechanical re-tooling, so operators can switch from a 30 ml beverage stick to an 80 ml jelly bar in minutes.
Core Parts on the SW-2830A
The images below show the electrical, pneumatic, and mechanical components that drive stick-pack output and determine long-term operating cost. Complete component list with part numbers is provided on the quotation sheet.
Siemens PLC Controller
Coordinates film pull length, seal jaw timing, temperature loops, and optional date printer triggering. Proven reliability with globally available spares.
Schneider Circuit Breaker
Schneider Easy9 overcurrent protection on all motor and heater circuits. Frequency converter also Schneider brand for stable main-motor speed control.
AirTAC Solenoid Valves
AirTAC 4V210 valves switch pneumatic flow to the longitudinal and cross seal jaw cylinders. Widely available in Southeast Asia, Latin America, and Africa for quick replacement.
Stick-Pack vs Flat Sachet vs Pillow Pouch - Which Format Fits?
Liquid single-serve products can be packed in three common formats. Choose based on consumer experience, shelf presentation, and downstream freezing or cold-chain handling.
Choose SW-2830A Stick-Pack When:
- Your product is drinkable jelly, stick ice pop, flavoured beverage, or drinking yogurt
- Consumer experience requires tearing open the end and drinking directly from the stick
- You need a long thin sachet that freezes efficiently in bulk trays
- Your fill volume is 10-150 ml and bag length is 50-200 mm
- You want a simple self-flow hopper with no pump seals to maintain
Choose a Different Format When:
- Flat retail sachet needed - use SW-1528 four-side-seal liquid machine
- Horizontal pillow-pouch ice pop - use SW-100 ice pop pillow pouch machine
- Powder or granule stick packs - use SW-2830B reciprocating stick pack machine
- High-viscosity paste or sauce - use SW-Y200/Y250/Y320 premade bag liquid machine
- Multi-lane high-speed liquid stick pack - use a multi-lane collar machine on request
When This Machine Is Not the Right Fit
The SW-2830A is a dedicated liquid stick-pack VFFS. It is not the right platform for powder or granule products (use the SW-2830B reciprocating stick pack machine or an auger-fed vertical machine instead), flat four-side-seal sachets (use the SW-1528), premade stand-up pouches (use the premade bag packing machine family), or spouted pouches (use the SW-CCS6 spout pouch filling and capping machine). For large-bag horizontal pillow-pouch ice pops, see the SW-100 ice pop pillow pouch machine.

What Our Clients Say
We run the SW-2830A on a drinkable jelly line with 80 ml sticks. The self-flow hopper is very easy to clean between flavour changes and we don't deal with pump seals like we used to on our old piston-fill machine. Output hits 80 bags per minute during stable runs. The dual temperature controllers were necessary for our PET/PE laminate - the end seals needed a higher temperature than the back seam and the independent controllers solved it on the first day of installation.
Siti R.
Production Manager - Jelly Snack Co-Packer, Indonesia
We bought the SW-2830A for stick ice pops in 40 ml and 80 ml formats for export to supermarket chains in the GCC. Linked-bag output was important for us because we freeze the linked chain in bulk trays before cartoning - it saves us a separation step. The machine has been stable for fourteen months of daily operation and we have only replaced the sealing strip once on schedule.
