A standard machine can produce anywhere from 50 to 120 bags per minute, while high-capacity versions can exceed 400 bags per minute.

Filling Systems for Precision

The filling station is arguably the most critical part of the machine, as it dictates accuracy, speed, and product waste. Matching the right filling system to the product is crucial for optimal performance.

• Auger Fillers for Powders: This is the go-to solution for powders. An auger filler uses a rotating screw to dispense a precise amount of powder into the pouch. The speed and duration of the screw's rotation control the fill volume, allowing for highly accurate dosing of products like protein powder, coffee, and spices.
• Multi-Head Weighers for Granules: For granular or irregularly shaped items, a multi-head weigher is the industry standard. This system uses multiple weighing buckets to create precise combinations that match the target weight. It's exceptionally accurate and fast, making it ideal for snacks, pet food, and hardware.
• Linear Weighers: A more economical choice for granules, linear weighers use vibrating channels to feed product into a weigh bucket. They are suitable for free-flowing, consistent-sized granules.
• Volumetric Cup Fillers: This system uses cups of a specific volume to dose free-flowing granules like sugar or rice. It's a simple, fast, and cost-effective method for products with consistent density.

Robust Sealing for Product Integrity

Once filled, the pouch must be sealed securely to protect the product from moisture, oxygen, light, and contaminants, thereby extending its shelf life. A strong, reliable seal is also crucial for preventing leaks during transportation and handling. Doypack machines use various sealing methods:

• Heat Sealing: This is the most common method, where heated jaws press the top of the pouch together, melting the inner sealant layers to create a hermetic seal. The temperature, pressure, and dwell time are precisely controlled to ensure a perfect seal without damaging the pouch or the product.
• Ultrasonic Sealing: This advanced technology uses high-frequency vibrations to generate frictional heat precisely at the seal area. It's ideal for sealing through product contamination (like dust) and is often used for heat-sensitive products. It creates strong, aesthetically pleasing seals and consumes less energy than traditional heat sealing.

Additional sealing options include applying zippers or caps before the final top seal, adding another layer of functionality and convenience for the end consumer.
