Which Pillow Packing Machine Fits Your Product?
Nine machines, one principle: form a pillow pouch from rollstock film around your product, seal both ends, and cut. The difference is how the product reaches the film (manual, chain conveyor, candy turnplate, turntable, tidying belt, or hopper and inclined conveyor) and how the film reaches the product (top, under, or rear). Choose by your product type and production line needs below. To compare this family against the others, see all ShengWei packing machine models in one index. Filling loose granules or powder into a back-seal pillow bag is a vertical machine job rather than a flow wrap one — see our vertical packing machines.
Top-Film vs Under-Film vs Rear-Film: Which Film Path?
Every model below makes the same pillow pouch. What changes is where the film roll sits and how the film meets your product, and that decides how gently a product is handled.
Film path by model, taken from each machine page. Rated sizes and speeds are in the specification table further down.
| Film path | How the film meets the product | Models | Typical products |
|---|---|---|---|
| Top-film (standard) | Film unwinds from a shaft above the conveyor and wraps over the top of the product. | SW-350A / 450A / 550A, SW-1000A, SW-1000B, SW-300A, SW-300B, SW-1200 | Biscuits, bread, bars, soap, hardware, candy; rigid or heavier items that film tension from above does not move |
| Under-film (film beneath feeding) | Film arrives from below the conveyor and the product is placed directly on top of it, with an open infeed above. | SW-350B / 450B | Small, light items such as candy, cookies, snack bars, small hardware and stationery |
| Rear-film (film back feeding) | Film is mounted at the rear of the machine and descends from above, so the product rides on a clean belt. | SW-150 | Sticky, soft or coated items such as preserved fruit, hawthorn flakes, mochi, jelly candy and moon cake |
How to choose a film path:
- Product sticks, smears or loses its shape on film: choose the rear-film SW-150.
- Product is small and light, placed by hand, and could be pushed out of line by film fed from above: choose a bottom film feed flow wrap machine (SW-350B / 450B).
- Product is rigid or heavier, or longer than the under-film range: choose the top-film SW-350A / 450A / 550A, which takes products up to 500 mm long on the SW-550A.
- Pieces must be oriented and fed without an operator: the turnplate, turntable, tidying-belt and sorting-tray lines below all use the top-film path.
- Check your product length, width and height against the specification table, then send a sample with your enquiry so the film path and infeed can be confirmed.
General Purpose Flow Wrappers
Versatile pillow wrappers for biscuits, bread, bars, soap, hardware, and semi-soft products. Differentiated by film path — top, under, or rear — which determines how delicately the product can be handled.
SW-350A / 450A / 550A
Multifunctional Pillow Wrapper
Biscuits, bread, candy bars, soap, hardware, dried dates, noodle cakes. Three frame sizes take film up to 350, 450, or 550 mm wide, for products 30–80, 50–160, or 50–200 mm wide. Standard top-film path — the workhorse of the pillow pouch catalogue.
- Film Path
- Standard top-film
- Speed
- 20–200 (350A) · 15–70 (450A / 550A) bags/min
- Best For
- General solid products, 3 sizes
SW-350B / 450B
Under-Film Pillow Wrapper
Candy, cookies, snack bars, small hardware, stationery. Film arrives from below the conveyor so product is placed directly onto it — compact footprint and gentler on delicate items than top-film.
- Film Path
- Under-film (below conveyor)
- Speed
- 40–230 bags/min
- Best For
- Compact footprint, small items
SW-150
Rear-Film Pillow Wrapper
Preserved fruit, hawthorn flakes, mochi, jelly candy, moon cake. Film descends from behind the machine onto the product, so the belt stays clean — the solution for sticky or soft items that would otherwise drag on film.
- Film Path
- Rear-film (from above)
- Speed
- 40–230 bags/min
- Best For
- Sticky, soft, or delicate items
Candy & Confectionery Lines
Integrated candy infeed + pillow wrapper combinations for hard candy, toffee, gummy, nougat, and chocolate. Turnplate or sorting-tray feeders replace manual placement for fully automatic throughput.
SW-1000A
Single Candy Turnplate
Hard candy, toffee, chocolate, individually wrapped sweets. A rotary candy turnplate with mold cavities orients each piece before the wrapper — the entry point to automatic candy pillow wrapping.
- Film Path
- Turnplate + top-film
- Speed
- 50–500 bags/min
- Best For
- Single-type candy wrapping
SW-1000B
Dual Candy Turnplate
Two candy types in one pouch — toffee + hard candy, chocolate + gummy, or any mixed assortment. Two synchronized turnplates feed the same wrapper so each finished pouch contains both types in precise ratios.
- Film Path
- Dual turnplates + top-film
- Speed
- 50–400 bags/min
- Best For
- Mixed-content candy packs
SW-300A
Turntable Packaging Line
Candy, nougat, rice bars, regular-shape snacks. A motorized turntable bulk-feeds product from tote bins or upstream equipment into the wrapper — a complete unattended production line rather than a stand-alone wrapper.
- Film Path
- Turntable feeder + top-film
- Speed
- 50–800 bags/min
- Best For
- Full auto candy production line
SW-1200
Three-Servo High Speed
Individual candy, gummy, hard sweet, small chocolate. A sorting tray combined with triple-servo film pull and seal jaws produces the catalogue's highest throughput — up to 1,200 pieces per minute.

Specialty Packaging Lines
Dedicated configurations for applications the general-purpose and candy platforms cannot handle — auto-sorted bars and cubes, and finished ice pops.
SW-300B
Tidying Feeding Line
Chocolate bars, chicken stock cubes, nougat bars, shaqima, rice cakes. A six-servo tidying belt aligns bars and cubes end-to-end before the wrapper — fully automatic orientation for products the turnplate cannot handle.

Select By Pouch Type
Every pillow packing machine produces the same finished format — a pillow pouch with a longitudinal fin seal down the back and transverse end seals at each end. The film wraps horizontally around the product; the seal pattern is inherent to the HFFS process.
Fin Seal Pillow
Back Seal Pillow
Need 3-side seal sachets, stick packs, or 4-side sachets? Those formats are made on vertical machines — see our Full Automatic Vertical Packing Machine category; the Collar Type Packing Machine category makes back-seal pillow bags. For doypack / zipper / spout pouches, see Premade Bag Packing Machine.

Send us a product sample →How a Pillow Flow Wrap Machine Works
All nine machines share the same four-step horizontal form-fill-seal (HFFS) cycle. The variable is how product enters the wrapper and how the film reaches the product — top-film, under-film, or rear-film.
01
Film Unwind & Feeding
Rollstock film (OPP/CPP, OPP/PE, PET/PE, BOPP, or composite laminate) mounts on a film shaft at the rear of the machine. The film is pulled through tension rollers that maintain consistent web tension. A photoelectric eye tracks print-registration marks on the film so that branded graphics, barcodes, and batch panels land in the correct position on every pouch — no manual film adjustment during the run.
02
Product Infeed & Film Forming
Product enters the machine on a belt conveyor, chain conveyor, or automatic feeding system (candy turnplate, turntable, tidying belt — depending on model). The flat film passes over a forming shoulder that wraps it into a continuous tube around the product. On standard top-film models the film arrives from above; on the SW-350B it arrives from below; on the SW-150 it descends from behind. Regardless of path, the film tube encases each product before any sealing begins.
03
Longitudinal (Center) Seal
Heated center-seal rollers press the overlapping film edges together along the length of the tube, forming the continuous back seam — the fin seal that gives the pillow pouch its name. Temperature and pressure are independently adjustable from the HMI touch screen so the same machine handles thin OPP/CPP for candy and thicker PET/PE for fresh produce without retooling.
04
End Seal, Cut & Discharge
Rotary or box-motion end-seal jaws clamp across the tube, sealing the front of one pouch and the rear of the next simultaneously. A built-in knife severs the two pouches. An optional date coder prints batch number and expiry on the seal. Finished pillow pouches discharge onto the output conveyor for collection, weight check, or downstream case packing. The HMI stores product recipes for fast changeover.
