SW-1022: Vertical FFS for Triangle Bags
The SW-1022 is a vertical form-fill-seal machine engineered specifically for the triangle bag format — a back-seal triangle bag, also called a pyramid bag. Film feeds from a rear-mounted roll, wraps around a purpose-designed forming tube, and is closed with a back seal and cross seals to produce a distinctive pyramid-shaped sachet that stands out on retail shelves and in impulse display racks.
Unlike conventional vertical packing machines that produce flat-profile back-seal or 3-side-seal sachets, the SW-1022 creates a three-dimensional pouch with visible product through the film window. This format is particularly popular for candy, chocolate balls, coated nuts, loose tea, ground spice, and seeds. The shape allows the filled product to settle into a stable pyramid, giving each pouch a consistent, premium appearance.
Standard equipment includes PLC control, servo-driven film pull (Panasonic / Delta / Yaskawa servo brands) with photoelectric tracking, adjustable sealing temperature, SUS304 stainless steel product-contact surfaces, and a compact single-phase 220V power supply. The machine is compatible with OPP/CPP, OPP/PE, PET/PE, and other heat-sealable composite films. Filling systems can be configured as volumetric cup, auger screw, or vibration feeder depending on the product type.

Tetrahedron, Triangle or Pyramid Bag: What the SW-1022 Makes
Buyers use several names for a bag with triangular faces. The name matters less than the material and how the bag is used.
Common names for triangle-shaped bags, and which one this machine produces.
| Name | What it usually means | Material | SW-1022 |
|---|---|---|---|
| Triangle bag, tetrahedron bag, pyramid pouch | A sealed retail sachet with triangular faces, formed from rollstock film on a vertical form-fill-seal machine. Used for candy, chocolate balls, nuts, seeds, spice and loose tea. | Heat-sealable film: OPP/CPP, OPP/PE, PET/PE, NYLON/PE | Yes. This is the bag the SW-1022 forms, with a back seal and cross seals around a triangular forming tube. |
| Pyramid tea bag (infusion bag) | A pyramid-shaped bag that is steeped in water, usually with a string and tag, made on a dedicated tea bag machine. | Mesh or filter material | Not part of the SW-1022 specification. The SW-1022 packs tea into sealed film triangle bags, not into infusion material. |
Not Related to Triangle Package Machinery
A search for a triangle packing machine also brings up Triangle Package Machinery, a separate US packaging machinery company. In that name, Triangle is a brand. ShengWei Machine is an independent manufacturer in Guangdong, China, with no connection to that company. On this page, triangle describes the shape of the bag the SW-1022 makes.

Note: The triangle bag is a specialized format suited for small-dose, high-value products. For standard flat sachets, see the SW-1328 three-side seal machine or the SW-1528 four-side seal machine.
How the Triangle Bag Forming Cycle Works
The entire forming-filling-sealing cycle runs continuously. Each triangle bag is completed in under one second at full speed. The servo-driven film pull and photoelectric tracking system keep print registration precise across the entire production run.
01
Film Unwind & Tracking
Film unwinds from the roll mounted at the rear of the machine. A photoelectric sensor reads the print registration mark on the film and adjusts the pull length in real time, ensuring every bag is cut at the correct position. Film width capacity is up to 220 mm, supporting bag widths from 25 mm to 140 mm.
02
Triangular Tube Forming
The film passes over a forming shoulder and wraps around a triangular-section forming tube — the core component unique to the SW-1022. The tube shapes the film into a three-sided profile instead of the conventional round tube used in standard vertical machines. A longitudinal seal runs along one edge to close the film into a continuous tube.
03
Product Filling
Product drops through the forming tube by gravity. The filling system — volumetric cup for granules, auger screw for powder, or vibration feeder for irregular pieces — meters the correct dose for each bag. A hopper above the forming tube holds the bulk product and feeds the metering system continuously. Filling accuracy depends on the feeder type and product density.
04
Sealing & Cutting
Heated seal jaws close across the tube from three directions. A knife built into the jaw assembly cuts between bags to separate them. The filled triangle bag drops onto the discharge chute. Temperature, jaw pressure, and dwell time are all adjustable via the touch screen to suit different film types and product weights.

Four Core Systems That Define the Triangle Bag
The SW-1022 is built around four purpose-designed systems that differentiate it from conventional back-seal or 3-side-seal vertical machines. Understanding these systems helps you evaluate whether the triangle bag format fits your product and production requirements. For larger-dose powder applications requiring auger filling in wider bags, the SW-420E/620E collar type auger powder machine offers bag widths up to 200 mm (SW-420E) or 300 mm (SW-620E).
① Triangular Forming Tube
The defining feature of the SW-1022. A precision-machined triangular-section forming tube replaces the round tube used in standard vertical machines. Film wraps around the three-sided profile, creating the pyramid bag geometry. The tube is removable for cleaning and available in multiple sizes to match different bag width requirements.
② PLC Touch Screen Control
A color touch screen displays packing speed, sealing temperature, bag length, and fault codes on a single screen. Product parameters can be saved and recalled for fast changeover between different SKUs. The PLC coordinates film pull, filling, and seal jaw timing in real time. Language and unit settings are configurable at the time of order — English, Spanish, Arabic, Russian, and other options available.
③ Interchangeable Filling Systems
The SW-1022 supports three filling methods depending on product type: volumetric measuring cups for free-flowing granules (candy, seeds, nuts), auger screw filler for fine powder (spice, coffee), and vibration feeder for irregular or sticky pieces. Switching between filling systems requires changing the dosing unit above the forming tube — the machine frame and control system remain the same.
④ Three-Direction Seal Jaw Assembly
Unlike conventional two-jaw cross-seal systems, the SW-1022 uses a three-direction seal jaw assembly that applies heat and pressure from three angles simultaneously. Seal temperature, dwell time, and jaw pressure are independently adjustable for each sealing direction via the touch screen panel. The jaw set is designed for quick replacement when worn.

Triangle Bag vs Standard Sachet — Which Format Do You Need?
Both formats start from rollstock film and produce sealed pouches on a vertical FFS machine. The key difference is bag geometry: the SW-1022 creates pyramid-shaped bags; standard machines create flat sachets. Choose based on your product type, target market, and retail display requirements.
Choose Triangle Bag (SW-1022) When:
- You need a distinctive, eye-catching bag shape for retail display or impulse sales
- Your product is small-dose (2–30 g) — candy, chocolate, nuts, tea, spice
- You want the bag itself to function as a mini display stand (the pyramid sits upright)
- Your market values novelty packaging as a differentiator (gift shops, specialty food, promotional items)
- Your production volume is moderate (a maximum of 60–100 bags/min) with compact floor space requirements
Choose Standard Vertical Machine When:
- You need a conventional flat sachet (back-seal, 3-side-seal, or 4-side-seal)
- Your dose weight exceeds 30 g or your bag width exceeds 140 mm
- You need multi-column output for high-volume sachet production
- Your packaging design requires a flat profile for carton boxing or display strips
When This Machine Is Not the Right Fit
The SW-1022 is designed for small-dose granule and powder products in triangle bag format only. For standard back-seal sachets, the SW-2030A back-seal granule machine or SW-2030D pendular small granule machine are better choices. For three-side-seal flat sachets, see the SW-1328 three-side-seal machine. For four-side-seal sachets (ketchup, shampoo), see the SW-1528 four-side-seal machine. For liquid filling, the SW-420F collar type liquid machine is the correct choice. For premade stand-up pouches, use the premade bag packing machine family.
