Customer Packaging Requirements

Packaging Solution

1. 16-Head Multihead Weigher for Beans, Rice and Grain

The primary packaging machine is equipped with a 16-head 2.5L multihead weigher.

This configuration is well suited for free-flowing granular products such as:

• beans

• rice

• grains

• pulses

• lentils

• seeds

The multihead weigher automatically selects the best weight combination to achieve fast and accurate dosing.

Compared with volumetric cup systems, a multihead weigher is especially useful when the customer requires better weight accuracy across different product sizes or densities.

2. Automatic 400g and 800g Small Bag Packing

The customer's retail packaging requirement includes:

• 400g bags

• 800g bags

After weighing, the product enters the vertical form-fill-seal machine.

The VFFS machine automatically completes:

film pulling → bag forming → weighing discharge → filling → sealing → coding → cutting

The customer uses laminated film and a back-sealed pillow bag format.

This type of packaging is commonly used for rice, beans and grain products in supermarkets and food distribution channels.

3. Automatic Counting and Secondary Bagging

This is the most important feature of the project.

Instead of manually collecting finished retail bags, the customer requires the individual packs to be automatically transferred to a secondary bagging machine.

The production line counts the finished bags and loads them into a large PE bag.

The target secondary packing format is:

20 small bags per large PE gusset bag

This substantially reduces manual labor during end-of-line packing.

4. One-to-One Secondary Bagging System

The project includes a dedicated one-to-one large bag packing machine connected to the high-speed primary packing machine.

The system consists of:

• finished bag conveying system

• automatic counting unit

• bag grouping system

• large PE film packing machine

• finished product conveyor

The secondary machine uses PE roll film to produce a large gusseted bag.

This creates a complete retail-to-wholesale packaging solution.

FAQ

What machine is suitable for packing beans into 400g and 800g bags?

A VFFS packing machine combined with a 16-head multihead weigher is suitable for automatically weighing and packing beans into 400g and 800g pillow bags.

Can the same machine pack rice and grains?

Yes. The same multihead weigher packing system can be used for sugar, rice, beans, grains, pulses, lentils, peas and similar free-flowing products.

Can finished retail bags be automatically packed into larger bags?

Yes. A secondary bagging machine can automatically count and group the finished retail packs before packing them into a larger PE bag.

How many small bags can be packed into one master bag?

For this Trinidad and Tobago project, the system was configured to pack 20 individual bags into one large PE gusset bag.
