Introduction to Masterbatch Gross Bagging Machine
A masterbatch gross bagging machine is an industrial weighing and filling solution engineered to pack plastic masterbatch granules into bags with consistent accuracy and controlled product flow. In gross weighing, the bag is clamped to the filling spout and the system measures the total weight while the material is being filled. This method is widely preferred for masterbatch applications because it supports stable feeding of free-flowing granules, helps maintain clean bag mouths, and enables reliable automation for high-volume packaging lines. Samirika Group manufactures robust gross bagging systems designed to reduce manual handling, improve repeatability, and support smooth downstream sealing or stitching operations.
Working Principle and Process Flow of Masterbatch Gross Bagging Machine
The process starts with masterbatch material feeding from a hopper or silo into the bagging spout through a suitable feeder. The bag is held by a pneumatic clamp, and the weighing mechanism monitors the gross weight in real-time as the product fills. The controller typically uses a fast feed stage for bulk filling and a slow feed stage for fine correction near the target weight, improving consistency and reducing overfill. Once the set weight is reached, the discharge gate closes automatically, the bag is released, and the filled bag is transferred to a conveyor for sealing, stitching, or palletizing. This flow supports repeatable bag weights, clean operation, and stable output in continuous production.
Types of Masterbatch Gross Bagging Machines
- Gravity Gross Bagger – Suitable for free-flowing masterbatch granules with simple, efficient filling control.
- Two-Stage Gross Bagger – Uses fast and dribble feed for better accuracy and reduced bag weight variation.
- Air-Assisted Gross Bagger – Improves flow stability and helps maintain a cleaner filling zone during operation.
- Bag Clamp Gross Bagger – Pneumatic bag holding system designed to reduce spillage and improve operator convenience.
- Integrated Conveyor Gross Bagger – Combines bag filling with conveying to sealing or stitching stations for streamlined handling.
