How to choose your open-mouth bag filling machine ?

Three fundamental questions to ask before choosing your bagging machine

Answering these three questions will naturally guide you towards the right category of machine.

01.

What is the nature of your product? (Powder or granules)

The type of product is the first selection criterion.

For powders (powdery products)

The main challenges: controlling volatility (dust), product deaeration for good compactness in the bag, and precise dosing.

Powder bagging machines, such as our HBM (Hygienic Bagging Machine) range, use bottom-up filling systems and screw feeders for clean, dense and contamination-free filling.

02.

What are your hygiene requirements?

Your industry imposes strict standards that define the design of your machine. At HALPAQ, we classify our bagging machines into three levels of finish.

Clean finish

Designed for efficiency and robustness in industrial environments with standard sanitary requirements. Ideal for chemicals, simple food processing (mills), minerals or construction materials.

Hygienic finish

The benchmark for Food & Feed. These machines — our HBM range — are the only washable bagging machines on the market. They feature:

• minimal retention areas,
• easy-to-clean surfaces,
• food contact certified components.

Objective: to eliminate any risk of cross-contamination.

Pharma finish

The highest level of requirement, designed for the pharmaceutical industry. These bagging machines comply with GMP (Good Manufacturing Practices) standards and incorporate:

• total containment solutions,
• Clean-in-Place (CIP) systems,
• high-quality materials for APIs, excipients and pharmaceutical products.

03.

What is your production rate?

Your requirement for bags per hour (BPH) determines the level of automation of your bagging machine.

Low rates (< 120SPH)

Our semi-automatic stations are ideal. They offer:

• high dosing precision,
• optimal flexibility for product changes,
• operator intervention limited to bag presentation and removal.

Medium to high speeds (120 to 1400+ SPH)

Our CBM and HBM automatic ranges set the standard. From the BM 1030 (~300 SPH) to the BM 1140 (~1400 SPH), they handle 100% of the bagging cycle:

• picking up the empty bag,
• opening,
• filling,
• closing,
• final evacuation.

Result: consistent performance and a high rate of production suited to industrial requirements.

Beyond the bagging machine: think “complete line”

At HALPAQ, we are both engineers and integrators. A high-performance bagging machine only reveals its full potential when part of a complete and coherent packaging line.

We design and integrate complete customised lines, from the storage silo to the pallet wrapper. Thanks to our expertise in 3D scanning and engineering, we provide turnkey solutions including:

• Precision dosing (screw feeder, vibrating feeder)
• Process safety (safety sieve, metal detector)
• Bag finishing (automatic sealer, sewing machine)
• Conveying and control (checkweigher, ejector)
• Robotic or conventional palletising

This comprehensive approach is our strength: offering you the ability to carry out large projects, even with an agile structure.
