Vacuum Packing Machine for Granules — YS-61XBK Back-Seal Brick Bag System
Automatic back-seal vacuum packing machine that forms, fills, evacuates and seals rigid vacuum brick bags for dry yeast, coffee powder, desiccants, seeds and chemical granules. Precise 1–100 g dosing, PLC touch-screen control and PID temperature accuracy within ±1°C — engineered and built in our Shanghai factory.
What Is the YS-61XBK Vacuum Packing Machine?
The YS-61XBK vacuum packing machine is an automatic back-seal (pillow-seal) vacuum packaging system manufactured by INMAYPACK that forms bags from roll film, volumetrically doses 1–100 g of granular product, evacuates air, and heat-seals compact vacuum brick bags at up to 25 bags per minute. It automates bag making, measuring, filling, vacuum sealing, cutting and counting in one continuous cycle, and is used across the food, pharmaceutical, chemical and cosmetics industries for oxygen-sensitive granules such as dry yeast, coffee powder, desiccants and seeds.

Why Manufacturers Choose the YS-61XBK Vacuum Packing Machine
Six engineering advantages that keep oxygen-sensitive granules shelf-stable and your production line running with minimal operator intervention.
True Vacuum Brick Bag Sealing
Air is fully evacuated before the back seal closes, compressing granules into a rigid brick block. Oxygen-sensitive products like active dry yeast and roasted coffee powder keep their potency and aroma for a dramatically extended shelf life without refrigeration.
One-Cycle Full Automation
Bag making, volumetric measuring, filling, vacuum sealing, cutting and counting complete automatically in a single continuous cycle. One operator supervises the entire line, cutting labor cost versus semi-automatic chamber vacuum sealers.
PLC + Touch Screen Control
PLC logic with an intuitive touch screen stores product recipes, while a stepper motor governs bag length with repeatable precision. Changeover between bag formats takes minutes — no mechanical cam adjustments required.
PID Sealing Within ±1°C
The intelligent temperature controller with PID regulation holds sealing-jaw temperature within one degree Centigrade. Consistent heat means hermetic vacuum seals on aluminum foil, BOPP/PE and Nylon/CPP laminates — batch after batch.
Accurate 1–100 g Dosing
Volumetric measuring covers 1 to 100 grams per bag — the sweet spot for retail yeast sachets, single-serve coffee bricks, desiccant packs and seed samples. Detection sensors verify each fill for accurate, giveaway-free packing.
Batch Coding & Custom Options
Add ribbon or thermal batch-number and date-code printing, counting output signals, and voltage variants to match your market's labeling regulations. Every machine is configured to customer requirements before factory acceptance testing.
What Can the YS-61XBK Vacuum Packing Machine Package?
Purpose-built for free-flowing granules and powders across four regulated industries where oxygen barrier and moisture protection determine shelf life.
Vacuum Brick Bag Packing Process — 6 Automatic Steps
Built by a Vacuum Packaging Machine Manufacturer You Can Audit
INMAYPACK has engineered flexible packaging machinery since 2009 from our factory in Jinshan District, Shanghai. Every YS-61XBK vacuum packing machine is assembled, wired and test-run in-house by our own technicians — not outsourced.
Before shipment, we run factory acceptance testing (FAT) with your actual granule product and your actual packaging film, then send you the full test video. You verify seal integrity, vacuum tightness and fill accuracy before the machine leaves Shanghai. Factory visits are welcome — we are 45 minutes from Hongqiao Airport.
Vacuum Packing Machine FAQ
The YS-61XBK is suitable for vacuum metered packaging of granular products in the food, medicine, chemical and cosmetics industries. Typical applications include active dry yeast, roasted coffee powder, desiccant granules, seeds, effervescent granules and fine chemical powders that require oxygen and moisture protection in a compact vacuum brick bag.
The machine doses 1 to 100 grams per bag and forms back-seal bags from 30 to 170 mm in length and 30 to 130 mm in width. Bag length is controlled by a stepper motor through the touch screen, so changing formats takes only a few minutes without mechanical adjustments.
Roll film is formed into a back-seal tube, granules are volumetrically measured and filled, air is evacuated to compress the product into a rigid brick, PID-controlled jaws heat-seal the bag hermetically, and finished bags are cut and counted automatically. All six steps run in one continuous cycle at 15 to 25 bags per minute.
Compatible laminates include BOPP/Polyethylene, Aluminium foil/Polyethylene, Paper/Polyethylene, Polyester/Aluminized/Polyethylene and Nylon/CPP. For long shelf life vacuum brick bags, we recommend high-barrier aluminum foil or aluminized laminates, and we verify your specific film during factory acceptance testing.
Yes. The YS-61XBK can be configured with batch number and date code printing as well as counting output according to your requirements. These options are specified at the ordering stage and tested together with your product before shipment.
Our standard process is an agreed initial payment to begin production, followed by factory acceptance testing (FAT) with your actual product and packaging film, and the agreed balance before shipment. You receive complete FAT videos showing seal quality, vacuum tightness and fill accuracy before the machine leaves our Shanghai factory.
