Why the DS320L 4-Lane Granule Packing Line fits your production

The DS320L 4-Lane Granule Packing Line is a vertical form-fill-seal machine: film unwinds from a reel, is formed into a bag over a forming collar, filled from a dosing system above, and sealed — all in one continuous cycle. Rated output: 30–45 cuts/min × 4 columns. Because the bag is made from flat film at the moment of packing, your packaging inventory is one or two film reels instead of thousands of premade bags — that is the main cost and logistics advantage over doypack lines.

Choose the model by fill range and bag size: the specification table lists both. A common mistake is buying for today's SKU and discovering six months later that the next product needs a longer bag or a bigger fill volume. If you run powder, granule and liquid variants of the same product family, ask us about keeping one VFFS platform and changing only the doser — it shortens operator training and spares inventory.

Key features that matter on the floor

• Output — 30–45 cuts/min × 4 columns, with realistic line efficiency planned at 60–70% of rated speed
• Sealing system — Twist edge gluing, back seal 8 mm
• Dosing accuracy — Swing cup, 1.5–3.75 g, ±7% — keeps fill-weight complaints and giveaway within tolerance
• Power supply — 220V / 50Hz, 8–10 KW
• Applications — Granules, Powders, Bulk materials
• Construction — GMP-grade SUS304 product-contact parts, CE certified
• Documentation — Manuals and remote video commissioning in English, Spanish, Portuguese, Vietnamese, Indonesian, Turkish and Arabic

How it works, step by step

1. Film transport — flat film is pulled from the reel over a forming collar, which shapes it into a tube.
2. Vertical sealing — the longitudinal sealer closes the tube's back seam, setting the bag width listed in the spec table.
3. Filling — the dosing system above (auger for powder, weigher for granules, pump for liquid) drops the product into the formed tube.
4. Horizontal sealing — cross-sealing jaws close the bag's top while simultaneously sealing the next bag's bottom, then cut them apart.
5. Discharge — finished bags drop to a take-away conveyor; bag length and fill volume are recipe-stored for fast changeover.

The whole cycle repeats continuously; a single operator supervises film supply and finished-bag collection.

Installation, compliance and after-sales

To quote accurately we need four things: your product and portion weight, target output per minute, the bag format you want (or a photo of a competitor's pack), and your plant voltage and compressed-air supply. With those, the quotation includes the line layout, film specification and delivery scope.

Every machine is tested and accepted at our 20,000 m² factory in Zhongshan, Guangdong, before dispatch. We ship with CE documentation, commission by remote video call in your working language, and stock spare parts for fast dispatch — the same parts list is used across our platforms, which keeps maintenance simple. PouchMfg is the oral-pouch machinery brand of PACKMATE (GUANGDONG) Co., Ltd., exporting to 60+ countries.
