Lin-pack focus on develop machinery that fills and seals premade pouches. Our ROTARY PREMADE POUCH MACHINE efficiently packages product into attractive premade bags that are as unique as your product. This bag type has exploded in popularity for its ability to differentiate a product from its competition on the shelf. A cost-effective alternative to rigid packaging, the premade pouch provides convenience and flexibility both to the manufacturer and end consumer.
1. BAG FEEDING & POUCH GRIPPING
The ROTARY PREMADE POUCH MACHINE offers three different types of bag feeding:
Linear belt: For zippered bags, pouches that are already filled with tray, spout pouch, or miscellaneous bag types
Stand up: For thin bags,, or pouches with tin tie
The Premade Pouch Machine will then grip and pick up bags from the bag magazine. These grippers are engineered for up to 2.5kg grip strength. This grip maintains strength over time so there is no sagging in the middle of the bag even after increased weight is added.
2. PRINTING / ZIPPER OPENING
Print lot numbers or use by dates at this station. An inkjet printer is recommended, however, if a thermal transfer printer is preferred by the customer, the printing must be done after the top of the pouch is open.
In preparation for product filling, the zipper on the bag needs to be opened. An accessible zipper is recommended, or the bags may be filled from the bottom of the pouch if the zipper is enclosed and cannot be opened without compromising the package.
3. POUCH OPENING/DETECTION
Vacuum suction secures the bag at this point in the cycle. Suckers open the pouch while suction keeps the bag on rotation. Sensors at the bottom of the bag confirm the presence of the pouch. If the sensor does not detect a bag, the pouch will not fill and will remain on rotation until it is sensed.
4. PRODUCT FILLING
The pouch is now ready to be filled with your product. When dispensing non-liquid product from an auger, multi-head weigher, or cup filler the product is filled with a funnel. If the product is liquid, it is dispensed with a nozzle.
5. OPTIONS (BASED UPON APPLICATION)
For powder products like flour, a dust collection hood option can be added.
For solid products, a vibratory settler can be added.
For liquid products, a secondary filling station can be added.
Gas flush and oxygen scavenger insertion can also be added as options.
Additional items are available based on your application.

7. HEAT SEALING
The Premade Pouch Machine creates a superior seal beginning with heat sealing, the first step in its two-step sealing system: Straight heat seal pattern
8. Heating sealing / DISCHARGE
The Premade Pouch Machine have second heat seal in its two-step sealing system: Textured heat seal pattern
At this point, the filled and sealed pouch is discharged from the machine. The entire rotary packaging process can produce between 20 to 60 filled pouches per minute depending upon model and configuration chosen as well as product application.
