Bag-in-Bag Premade Pouch Packing Machine for Long Packets

Weighing Hoppers That Accommodate the Full Packet Length

The multihead weigher uses hoppers designed to accommodate long packets. Hopper geometry is selected around the complete filled pack, including its sealed ends, so the product has sufficient room during weighing and release.

Smart Weigh reviews packet length, width, thickness and the required batch volume together. This helps reduce the risk of long packs catching across the hopper opening or remaining behind during discharge.

A Discharge Chute Designed for Faster Transfer
The weigher’s discharge chute is shaped to help long packets pass through quickly and smoothly. Its passage is matched to the product geometry to reduce catching and blockage as the weighed batch leaves the combination weigher.
The design supports a more consistent transfer to the pouch machine’s filling section, reducing interruptions caused by packets held back in the chute.

A Filling Funnel Built Around the Same Product Geometry
The pouch machine’s filling funnel follows the same design approach as the weigher and discharge chute. It provides a matched passage for the long packets as they enter the outer pouch.
By reducing blockage at the final loading stage, the funnel helps the complete weighed batch reach the intended pouch more reliably. This improves filling consistency and the successful completion of each loading cycle.

Weighing and Filling Selected Together
Smart Weigh reviews the weighing and pouch-loading sections as one product path. Hopper capacity, discharge clearance, funnel opening and outer-pouch dimensions are considered together when configuring the system.

The aim is to move the weighed batch through the complete transfer route within the pouch-filling stage.

1. Feed the Individually Packed Products

A matched conveyor supplies the long inner packs to the multihead weigher. Conveyor selection accounts for the packet shape, available installation space and required output.

2. Form the Target Batch
The combination weigher measures the inner packs and selects a batch for the specified target weight. The dedicated hoppers accommodate the elongated products during weighing and discharge.

3. Open and Fill the Outer Pouch
The rotary machine picks up and opens a premade pouch. The weighed batch passes through the discharge chute and the matched filling funnel into the waiting bag.

4. Seal and Discharge
The filled outer pouch is sealed and transferred out of the machine for collection or optional downstream inspection.

This configuration is intended for bag-in-bag projects involving long or strip-shaped inner packs. Applications can be assessed for individually wrapped snack sticks, strip-shaped snack packs and elongated vacuum pouches.

Smart Weigh evaluates the actual filled products because packet flexibility, thickness and sealed ends can affect hopper discharge and pouch entry. The proposed outer bag must also provide room for the complete batch and a clear sealing area.
