Product Description
The Meatech MT-GBP-8SR automatic weigh-fill bag packaging machine combines a multihead combination weigher with an 8-station rotary give-bag packaging system to deliver precise, high-speed automatic weighing, filling, and sealing of pre-formed bags — replacing a minimum of seven manual packaging operators on a single line. The system is designed as the final stage of Meatech's chicken, meatball, kebab, and IQF vegetable processing lines, receiving product from the upstream processing or freezing stage and delivering sealed, labelled retail or food-service packs ready for cold-chain dispatch.
Give-bag packaging — where pre-formed pouches are fed into the machine one at a time and opened, filled, sealed, and discharged in a continuous rotary cycle — is the preferred retail packaging format for fresh and frozen poultry portions, IQF meatballs, diced meat, and marinated ready-to-cook products. It accommodates a wide range of pouch formats (flat bags, stand-up pouches, doypacks, zipper bags, gusset bags, corner-spout pouches) on the same machine by changing the funnel and adjusting grip spacing from the 10-inch touchscreen — a changeover that takes approximately 15 minutes without tools.
The MT-GBP-8SR uses mechanical transmission rather than servo drive — a deliberate engineering choice that delivers greater long-term durability under continuous 24-hour industrial operation, with a published maintenance schedule of one day off per month. All surfaces in contact with food product are SUS304 or SUS316 food-grade stainless steel. Sensors at the bag-feeding, opening, filling, and sealing stations ensure that empty, malformed, or un-opened bags are detected and ejected without filling or sealing — eliminating the wasted product and rejected packs that result from these faults on machines without sensor protection.

Solution Applications — Line Position
In a Meatech processing line, the MT-GBP-8SR is the terminal packaging stage — positioned after the IQF tunnel freezer, cooking tunnel, or final checkweigher, and before cold-chain dispatch or palletising. It is the last machine in the line and the one that defines the retail presentation format of the finished product.
Meatech Solution | Role of MT-GBP-8SR in the Line |
Chicken Nuggets & Patty Line | Terminal packaging stage after IQF freezing. Receives frozen chicken nuggets and patties from the IQF tunnel and fills pre-printed retail pouches at 15–25 bags/min. The zipper bag format is widely used for retail nugget packs. The weigher integration ensures declared weight compliance without manual check-weighing. |
Meatball Processing Line | Packages IQF frozen meatballs and fish balls into retail stand-up pouches or flat bags. The free-flowing IQF output feeds the multihead weigher directly without manual handling — the weigher achieves ±1 g weighing accuracy into each bag. |
Kebab & Shawarma Line | Packages retail-format IQF frozen kebab skewers into flat bags or stand-up pouches. Product is gravity-fed or elevator-fed from the IQF tunnel to the weigher. The MT-GBP-8SR's flexible bag format range accommodates the elongated skewer format in appropriately sized flat bags. |
IQF Vegetable Lines | Terminal packaging stage for IQF sweet corn, edamame, green peas, mixed vegetables, and other free-flowing frozen vegetable products. Feeds directly from the IQF line gravimetric blending system or weigher. The give-bag format with zipper closure is preferred for retail frozen vegetable pouches in export markets. |
Central Kitchen Pre-Processing | Packages portioned and weighed fresh or chilled meat products into flat bags or doypacks for chilled distribution to outlet networks. Where the central kitchen requires multiple bag sizes for different SKUs, the 15-minute bag changeover allows rapid format switching between product runs. |
Compatible Pouch Format Guide
The MT-GBP-8SR handles all standard pre-formed pouch formats. The following guide matches common Meatech product types to the recommended pouch format:
Product Type | Recommended Pouch Format | Key Reason |
IQF chicken nuggets / patties | Stand-up doypack with zipper | Retail shelf display; resealable for consumer convenience |
IQF meatballs / fish balls | Flat bag or stand-up with zipper | Free-flowing product; zipper preferred for retail |

Jerky strips (snack pack) | Stand-up doypack with zipper | Retail snack format; nitrogen-flush option for shelf life |
FAQ
Q: How does the MT-GBP-8SR integrate with the upstream Meatech processing line?
A: The MT-GBP-8SR is fed by a bowl elevator that lifts product from the IQF tunnel or processing line conveyor to the multihead weigher intake. The weigher meters product into each bag at the target weight; the rotary give-bag machine below handles bag feeding, opening, filling, sealing, and discharge. The complete system — bowl elevator, weigher, and give-bag machine — is delivered as an integrated unit by Meatech, with the elevator height and weigher-to-machine interface engineered to match the specific line layout.
Q: What bag sizes are compatible, and how quickly can the machine change between bag sizes?
A: The MT-GBP-8SR handles bag widths from 100 to 210 mm and bag lengths from 100 to 300 mm — covering the standard retail pouch size range for 250 g to 2 kg product packs. Bag size changes within this range are made by adjusting grip spacing using two buttons on the 10-inch touchscreen and changing the funnel. The full changeover takes approximately 15 minutes with no tools required, making multi-format operation on a single machine practical for central kitchen and multi-SKU packaging operations.
Q: Does the machine work with pre-printed branded pouches?
A: Yes. The MT-GBP-8SR is designed to feed pre-printed customer pouches — including printed flat bags, doypacks, stand-up pouches with zipper, and custom-design pouches — from a standard pouch magazine. The machine's sensor system detects pouch orientation and position during feeding and rejects misaligned pouches without filling or sealing them, protecting printed pouch inventory from waste. Pouch specification requirements (width tolerance ±1.5 mm, length tolerance ±2.0 mm, no static electricity, no condensation) ensure reliable feed performance.
Q: How many operators does the MT-GBP-8SR require, and what labour does it replace?
A: One operator is sufficient to monitor the MT-GBP-8SR — loading the pouch magazine, monitoring the weigher, and clearing occasional rejects. The machine replaces a minimum of seven manual packaging operators performing equivalent weighing, bag-opening, filling, and sealing functions. For operations currently using manual packaging teams, the labour cost saving from a single MT-GBP-8SR installation typically produces a payback period of 12–18 months depending on local labour rates and production volume.
Q: What is the difference between the give-bag format and thermoforming packaging (MT-HFV)?
A: Give-bag packaging (MT-GBP) uses pre-formed pouches — bags that are manufactured separately and supplied in stacks or rolls. Thermoforming packaging (MT-HFV) forms the lower tray from film roll in-line during the packaging cycle. Give-bag is preferred for IQF frozen products and free-flowing products where a vertical fill-and-seal format is more practical than a horizontal tray format. Thermoforming is preferred for sliced fresh meat products where tray presentation is required. Both formats can be used within the same processing facility serving different product SKUs.
