8-station rotary vacuum premade bag packaging machine, 20–55bpm, vacuum bag opening, support zipper/doypack/flat bags, 304 stainless steel, for pet food/nuts/grain, free sample test.
This rotary vacuum bag packaging machine TY series is a multi-station rotary premade pouch filling and sealing equipment, completely different from vertical form-fill-seal VFFS machines that make bags from film roll. It adopts 8-station rotary indexing design, specially matched with prefabricated finished bags including zipper bags, stand-up gusset bags, back-seal flat pouches and special shaped bags. The whole machine integrates vacuum bag opening, material filling, top sealing, heat pressing and finished bag output into one automatic cycle, with stable running speed 20–55bpm.
Equipped with vacuum suction bag opening mechanism, it can firmly open flat pre-made bags without bag slippage or breakage. The full stainless steel frame meets food and pharmaceutical sanitary standards, with three intelligent alarm systems for no-bag, overload and low air pressure. Two models TY-8S and TY-8SL cover two width ranges of premade pouches, widely matched with multihead weighers, screw powder fillers, liquid dosing pumps and manual feeding platforms. This rotary premade bagger is widely used in pet food, dried fruit, grain, seasoning, frozen food, snack and daily chemical packaging workshops, greatly reducing manual bag placement labor and improving finished bag appearance uniformity and production stability.
Core Advantages
8-Station Rotary Indexing Cycle Design High Stable Output
8-position rotary turntable independent station separation design, each station completes different processes simultaneously (bag pick-up, vacuum opening, filling, sealing, cooling, output) without waiting downtime, speed adjustable 20–55bpm
Synchronous cam indexing positioning system ensures each bag stops at precise station position, avoids filling deviation and sealing misalignment, greatly reduces defective pouch rate
Separate independent stations avoid cross-contamination between different batches of products, suitable for frequent SKU switching in multi-product factories
Vacuum Suction Bag Opening System Adaptable To All Kinds Of Premade Pouches
Built-in double vacuum suction cup bag opening structure, negative pressure firmly opens flat prefabricated bags, solves the problem of thin composite film bags unable to open automatically
Compatible with multi-layer composite bags, kraft paper stand-up bags, aluminum foil zipper bags, transparent plastic back-seal bags; support special shaped premade pouches for food and daily chemicals
Dual suction cup adjustable spacing, adapt bag width range 80–200mm, automatic fine-tuning for different bag thickness without manual mechanical adjustment
Multi-Style Premade Bag Compatibility One Machine Realizes Multiple Packaging Forms
Support 8 mainstream premade bag types: flat back seal bag, zipper stand-up bag, gusset bottom bag, special shaped bread bag, doypack stand pouch, small retail sachet, vacuum storage bag, hole hanging retail bag
Quick-change bag gripper fixture without tools, complete bag format switching within 15 minutes, no need to replace the whole turntable mould
Two model options: TY-8S for medium wide bags 100–200mm width; TY-8SL for narrow small pouches 80–200mm width, cover small retail single packs to large family bulk bags
Triple Intelligent Safety Alarm System Reduce Equipment Fault Loss
Three independent alarm monitoring modules: no bag / no material anti-empty sealing alarm, equipment overload stop alarm, low air pressure reminder alarm
When no premade bag is detected at the bag pick-up station, the machine automatically skips filling and sealing procedures to avoid empty sealing waste of bags
Overload sensor real-time monitor turntable and sealing jaw load, automatically stop to protect mechanical structure; low air pressure alarm reminds air compressor maintenance to prevent vacuum opening failure
Low Noise Sanitary Stainless Steel Body Easy Wash-Down
Whole machine frame and product contact parts adopt food grade 304 stainless steel, smooth mirror surface without residue dead corners, suitable for high-humidity frozen food, aquatic and snack production workshops
Precision silent cam drive control, overall running noise controlled within 75dB at 1 meter distance, meet factory environmental noise standard without disturbing workshop workers
Detachable sealing jaw, suction cup and material receiving hopper, can be directly washed with water gun for residual powder, crumbs and oil stains cleaning
Standard Conveyor Output & Wide Auxiliary Equipment Matching Interface
Finished bags automatically drop onto belt conveyor for continuous output, can directly connect downstream weight checkers, metal detectors and box filling machines to form full automatic unmanned packaging line
Standard reserved signal linkage port for multihead weighing fillers, powder screw feeders, liquid filling pumps and manual feeding stations, realize synchronous start-stop linkage with upstream dosing equipment
Air consumption stable 0.3–0.4m³/min under 5–8kg compression, low air loss design to reduce long-term air compressor energy consumption cost

Wide Application Premade Bag Packaging Scenarios
This rotary vacuum premade bag packaging machine targets automatic filling & sealing of prefabricated finished pouches, widely deployed in food, pet feed, grain and daily chemical mass production factories:
Pet Food & Animal Feed Stand-Up Zipper Bag Packaging
Suitable for pet dry food kibble, cat litter, fish feed and dog snack stand-up zipper bags. Large capacity premade pouches keep feed fresh, vacuum bag opening avoids lightweight feed bags being sucked and deformed. High speed 55bpm meets large pet food factory daily mass packaging demand.
Adapt to dried cranberry, mixed nut, potato chip and popcorn zipper retail bags, hanging hole premade pouches for supermarket shelf sales. Quick-change bag fixture supports multiple SKU nut bag formats without long downtime switching.
Grain, Cereal & Seasoning Back-Seal Flat Bag Packaging
Used for rice gusset bags, mixed grain composite pouches, chili powder and spice flat back-seal premade bags. Vacuum suction opening stably handles heavy thick kraft grain bags without bag falling off during filling process.
Frozen Aquatic & Daily Chemical Special Shaped Bag Packaging
Fit for frozen seafood premade vacuum storage bags, facial mask sachets, laundry detergent powder zipper pouches and special shaped bread packaging bags. Multi-station rotary design ensures uniform sealing effect for high barrier frozen and cosmetic composite films.
Full Automatic Rotary Premade Bag Working Flow
Premade Bag Loading
Workers stack prefabricated finished bags on bag feeding rack, turntable suction cup automatically picks single bag and transfers to opening station
Vacuum Suction Bag Opening
Double vacuum suction cups hold bag front and back, negative pressure separates bag layers to fully open pouch mouth for filling
Quantitative Material Filling
Upstream matched filler drops measured granular/powder/liquid materials into open premade bag, sensor detects material weight to avoid underfilling

Frequently Asked Questions About Rotary Vacuum Premade Bag Packaging Machine
What is the core difference between rotary premade bag machine and VFFS vertical packaging machine?
Rotary bag machine uses finished premade bags (zipper/doypack/flat bags) directly, no film roll bag forming; VFFS machine forms bags from plastic film roll. Rotary machine is more suitable for high-end retail zipper bags with high appearance requirements.
How many bag styles can TY series rotary packaging machine support?
It supports 8 mainstream premade bag types: flat back seal bag, zipper stand-up bag, gusset doypack, hanging hole retail bag, special shaped bread bag, aluminum foil vacuum storage bag, kraft paper grain bag and small cosmetic sachet.
What is the maximum stable running speed of this rotary vacuum bag packer?
Adjustable speed range 20–55 bags per minute, the machine can continuously run at 55bpm without mechanical jamming under standard premade bag size specification.
Can the machine automatically stop when there is no premade bag?
Yes, equipped with no-bag & no-material detection sensor, the machine skips filling and sealing actions automatically to avoid empty sealed waste bags, and triggers light alarm to remind workers to replenish bags.
Can this rotary bag machine connect with multihead weighers and inline check weighers?
Standard reserved synchronous signal interface, can seamlessly link multihead filling weighers, screw powder feeders and our full series inline check weighers to form closed-loop automatic packaging & weight sorting production line.
