Flat Seal Assembly

• Used in packaging lines for food products such as snacks, coffee, and frozen goods.
• Applicable in pharmaceutical packaging to ensure sterile and secure seals for medical devices and drugs.
• Utilised in chemical industries for sealing bags of powders, granules, and other bulk materials.
• Suitable for consumer goods packaging, including pet food, detergents, and horticultural products.

Typical throughput

Throughput for this class of equipment typically ranges from 10 to 60 bags per minute, depending on bag size and product characteristics.

Power supply

Units of this type commonly require a standard industrial electrical supply, typically 230V or 400V, 3-phase, along with a compressed air supply for pneumatic operation.

Bag material compatibility

This equipment is typically compatible with a wide range of heat-sealable film materials, including laminates, polyethylene, and polypropylene.

Seal width

Commonly, the seal width for flat seal assemblies can be adjusted, typically ranging from 5mm to 15mm.

Operating pressure

Pneumatically operated systems commonly require an air pressure of 6-8 bar for optimal performance.

Integration

Units are typically designed for integration into existing vertical form fill seal (VFFS) or horizontal form fill seal (HFFS) packaging machines.

• What is the primary benefit of a flat seal assembly?

  The primary benefit is the reduction of wrinkles in the seal area, which significantly enhances seal integrity and improves the aesthetic appearance of the final package.

• How does this assembly prevent wrinkles?

• Is this unit suitable for all bag sizes?

• What maintenance is typically required for a flat seal assembly?

• Can this unit be retrofitted to existing packaging machines?

Used sealing machines are generally valued for their durability and long operational life. Buyers typically prioritize machines with clear maintenance histories and minimal wear on sealing components. Key considerations include film compatibility, seal quality consistency, and ease of adjustment. Reputable models tend to retain functionality well across multiple applications. Industry sentiment suggests these machines offer strong value when sourced from reliable vendors, though operators should verify calibration settings and test seal integrity before full production use.
