The pneumatic carton sealing machine in the KPW-ZFX series is the automatic, compressed-air-driven equipment for closing and sealing cardboard boxes with adhesive tape, available in two models with completely different box sizes — the ZFX30 for small boxes (length 130–250 mm, width 80–200 mm, height 90–200 mm) and the ZFX50 for medium and large boxes (length 200–600 mm, width 150–500 mm, height 150–500 mm) — at a rate of 20 boxes per minute for the compact model and 18 m/min linear speed for the industrial model.
Unlike purely electric-driven sealing equipment, the KPW-ZFX pneumatic carton sealing machine uses compressed air at 0,6 MPa (50 NL/min) to drive the pressing and tape-feed mechanisms, which gives it a more constant application force that is less dependent on voltage variations in the hall's electrical network. Both models operate at 220V/110V single-phase for the electronic control component and require a connection to the existing compressed-air installation in the hall. Key Advantages of the KPW-ZFX Pneumatic Carton Sealing Machine
• Pneumatic drive — constant pressing force regardless of network variations — the KPW-ZFX pneumatic carton sealing machine uses compressed air to drive the pressing arms and the tape-feed mechanism; the force applied to the adhesive tape is determined by the air pressure (0,6 MPa), not by the electrical voltage, which eliminates the adhesion variations caused by the voltage fluctuations frequent in industrial halls with high current consumption.
• ZFX30 — the only model dedicated to small boxes (max 250×200×200 mm) — the ZFX30 pneumatic carton sealing machine is designed exclusively for small boxes, with a maximum length of 250 mm, maximum width of 200 mm and maximum height of 200 mm; in this size class, general-purpose equipment has difficulty centering and uniformly applying the tape on narrow and low boxes; the ZFX30 solves exactly this problem with guides calibrated for small boxes.
• 20 boxes per minute on the ZFX30 — 1.200 boxes per hour — the ZFX30 pneumatic carton sealing machine processes 20 boxes per minute in continuous operation, equivalent to 1.200 boxes per hour; the pace exceeds the capacity of general-purpose electric models and makes the ZFX30 the choice for dispatch lines with a high volume of small, uniform parcels.
• ZFX50 — adhesive tape up to 75 mm wide, the widest in both KPW series — the ZFX50 pneumatic carton sealing machine accepts adhesive tape in widths of 48, 60 and 75 mm; the 75 mm tape offers the largest adhesion surface available in the KPW range and is necessary for heavy boxes of corrugated or double-corrugated cardboard where a narrower tape would fail during handling with a pallet truck or forklift.
• Two models with completely different sizes — complete coverage along the small-large axis — the KPW-ZFX pneumatic carton sealing machine together covers a broad spectrum: the ZFX30 from boxes of 130×80×90 mm (boxes for cosmetic, pharmaceutical, jewelry products) to the ZFX50 for boxes of 600×500×500 mm (household appliances, equipment, flat-pack furniture); a customer with two different product lines can choose a model dedicated to each format.
• Compact footprint relative to capacity — ZFX30 at 1.570×800×1.200 mm — the ZFX30 pneumatic carton sealing machine occupies a space of only 1,57 m × 0,80 m on the hall floor, with a height of 1,20 m; for a capacity of 20 boxes per minute, the footprint is small and allows installation in narrow dispatch spaces or in packaging lines with limited floor area.
• 220V/110V single-phase supply — simple installation for the electrical component — the KPW-ZFX pneumatic carton sealing machine requires a single single-phase 220V or 110V outlet for the electronic control module; the electrical installation is equivalent to any office equipment, without three-phase boards or dedicated circuits; the only special connection is the one to the compressed-air installation.
• Simultaneous top and bottom sealing — a single pass, box fully closed — the KPW-ZFX pneumatic carton sealing machine applies adhesive tape to the upper and lower seams of the box in a single pass through the equipment; the box enters with the flaps open and exits fully sealed on both faces, ready for labeling, strapping or palletizing.

ZFX30 or ZFX50 — How to Choose the Right Model of the Pneumatic Carton Sealing Machine
The choice between the two models of the KPW-ZFX pneumatic carton sealing machine is made solely according to the dimensions of the boxes in the packaging flow:
• KPW-ZFX30 — for small, uniform boxes (max L 250 × W 200 × H 200 mm) — the ZFX30 pneumatic carton sealing machine is the choice for operators who ship a dominant small-box format and need equipment calibrated specifically for this size; pharmaceuticals, cosmetics, jewelry, small auto parts, individually packaged food products — wherever boxes are small and volume is high, the ZFX30 offers 20 boxes per minute with maximum sealing uniformity.
• KPW-ZFX50 — for medium and large boxes (L 200–600 × W 150–500 × H 150–500 mm) — the ZFX50 pneumatic carton sealing machine covers the standard range of corrugated cardboard boxes used in distribution, storage and dispatch of medium and large products; the tape up to 75 mm ensures robust sealing on heavy boxes that will be handled mechanically during palletizing and transport; the line speed of 18 m/min allows integration into packaging lines with a continuous conveyor.
• If the flow includes both formats — the KPW-ZFX pneumatic carton sealing machine can be purchased in both models for parallel lines with different formats, each model operating optimally at its specific size instead of forcing a general-purpose unit to work at the limit of the minimum or maximum accepted dimensions.
The KPW-ZFX Pneumatic Carton Sealing Machine versus the KPW-FX Electric Models
The UZINEX range of equipment for sealing corrugated cardboard boxes includes both purely electric-driven models (the KPW-FX series) and pneumatically driven models (the KPW-ZFX series); the difference between the two series is more than a technical preference — it is a decision based on the existing infrastructure and the type of production:
• Choose the KPW-ZFX pneumatic carton sealing machine if the hall already has a functional compressed-air installation at 0,6 MPa with an available flow of at least 50 NL/min, if you seal exclusively small boxes (ZFX30) or if you need the widest 75 mm tape available in the range (ZFX50); the existing pneumatic infrastructure makes installing the ZFX simpler than it seems.
• Choose the electric KPW-FX models if the hall has no compressed-air installation or if the air consumption of other equipment leaves insufficient flow for the sealer; the FX series operates at 220V without air consumption and is more suitable for packaging spaces without pneumatic infrastructure.
• The pneumatic advantage for very high volumes — the ZFX30 pneumatic carton sealing machine reaches 20 boxes per minute, exceeding the capacity of standard electric models; for dispatch lines with volume peaks of over 1.000 boxes per hour on a single small format, the ZFX30 is the only solution in the KPW range that covers this need.
Applications — Where the KPW-ZFX Pneumatic Carton Sealing Machine Works
• Pharmaceuticals and cosmetics — ZFX30 for small standardized boxes — the ZFX30 pneumatic carton sealing machine is ideal for packaging lines in the pharmaceutical and cosmetic industry where boxes have small and uniform dimensions (vials, tubes, tablets, care sets); the uniformity of pneumatic sealing on small boxes is superior to manual sealing or to equipment calibrated for large sizes.
• E-commerce with a high volume of small parcels — e-commerce warehouses that ship hundreds or thousands of small parcels daily in formats under 250×200×200 mm benefit from the 20 boxes/min capacity of the ZFX30 pneumatic carton sealing machine; over 6–8 hours of operation per day, a single ZFX30 unit processes 7.200–9.600 small parcels.
• Food product distribution — ZFX50 for standard corrugated cardboard boxes — the ZFX50 pneumatic carton sealing machine seals the standard corrugated cardboard boxes used in the distribution of packaged food products; the 75 mm tape ensures robust sealing on boxes weighing 5–15 kg that are frequently handled with pallet trucks and forklifts in refrigerated and ambient warehouses.
• Manufacturers with a conveyor packaging line — the ZFX50 pneumatic carton sealing machine, with a linear speed of 18 m/min, integrates into lines with a continuous conveyor after the filling and manual flap-closing stations; synchronization with the conveyor speed is possible by adjusting the air pressure and the feed speed.
• Warehouses with existing pneumatic infrastructure — halls with air compressors installed for other equipment (screwdriver guns, pneumatic presses, lifting devices) can add the KPW-ZFX pneumatic carton sealing machine to the existing installation without additional investment in infrastructure; the consumption of 50 NL/min at 0,6 MPa is modest relative to the capacity of a standard industrial compressor.
• Auto parts and industrial components — ZFX50 with wide 75 mm tape — boxes with auto parts or metal components reach weights of 10–20 kg and require wide tape to distribute the sealing force over a larger surface; the ZFX50 pneumatic carton sealing machine with 75 mm tape ensures the box remains sealed throughout the repeated mechanical handling from dispatch to recipient.
Frequently Asked Questions about the KPW-ZFX Pneumatic Carton Sealing Machine
What compressed-air pressure and flow does the KPW-ZFX pneumatic carton sealing machine require?
The KPW-ZFX pneumatic carton sealing machine requires compressed air at a pressure of 0,6 MPa (6 bar) with a flow of 50 NL/min; these values are compatible with any industrial compressor with a flow of 100 NL/min and above; the air installation must ensure a constant pressure of 0,6 MPa at the equipment's connection for correct operation of the pneumatic mechanisms. Can the KPW-ZFX pneumatic carton sealing machine operate without compressed air?
No. The KPW-ZFX pneumatic carton sealing machine uses compressed air to drive the pressing and tape-feed mechanisms; without compressed air at a pressure of 0,6 MPa, the equipment cannot operate; if the hall does not have a compressed-air installation, the purely electric-driven models in the KPW-FX series are the suitable alternative. Can the ZFX30 seal boxes longer than 250 mm?
No. The ZFX30 pneumatic carton sealing machine has maximum size limits of 250 mm length, 200 mm width and 200 mm height; boxes that exceed these dimensions on any axis must be processed with the ZFX50 model (length up to 600 mm, width and height up to 500 mm); choosing the correct model at purchase is essential for optimal operation of the equipment. What adhesive tape is used on the KPW-ZFX pneumatic carton sealing machine?
The ZFX30 pneumatic carton sealing machine uses 48 mm wide adhesive tape rolls, while the ZFX50 accepts widths of 48, 60 and 75 mm; the type of tape (OPP with acrylic or hot-melt adhesive) is chosen according to the temperature and humidity of the storage and transport environment; the rolls are available from all local packaging consumables suppliers without source constraints.
