Carton Sealing Machine KPW-FX | 1000 Boxes/Hour | 5 Models

The carton sealing machine in the KPW-FX series is the automatic equipment for closing and sealing cardboard boxes with adhesive tape, available in five models with different overall dimensions (covering boxes with widths between 80 and 500 mm, heights between 40 and 600 mm and unlimited length) at a rate of up to 1.000 boxes per hour, with a consumption of only 240W at 220V single-phase.

The KPW-FX carton sealing machine applies adhesive tape simultaneously to the top flap and the base of the box in a single pass, without manual intervention after the initial dimension setting. The five models in the series (KPW-FX5050X, KPW-FX5050, KPW-FX4050, KPW-FX4030 and KPW-FX6050) cover different ranges of width, height and tape width, so that every operator finds the configuration suited to the exact type of boxes in their packaging flow.

Key Advantages of the KPW-FX Carton Sealing Machine

• 1.000 boxes sealed per hour: industrial pace with a single operator. The KPW-FX carton sealing machine processes up to 1.000 boxes per hour in continuous operation; a single operator feeds the boxes onto the conveyor and collects them at the exit, with no additional pressing, taping or manual tape verification on each box; at a flow of 500 boxes per hour, the difference compared to manual sealing means at least two operators eliminated from this station.

• Unlimited box length: all models in the series. The KPW-FX carton sealing machine imposes no length restriction on the box along the feed axis; short boxes of 150 mm and long boxes of 800 mm or more pass through the same equipment without mechanical adjustments; the only dimensions that define the choice of model are the width and height of the box.

• Five models: complete coverage for any box size. The KPW-FX carton sealing machine is available in distinct configurations (FX5050X, FX5050, FX4050, FX4030, FX6050) with different ranges of width (80–500 mm), height (40–600 mm) and tape width (30–70 mm); the operator who seals small, light boxes chooses a different model than the operator with large, tall boxes, without paying for capacity they do not need.

• Adhesive tape 30–70 mm wide depending on the model: solid sealing adapted to the box type. The KPW-FX carton sealing machine uses standard rolls of packaging adhesive tape (OPP, acrylic or hot-melt), available from all local packaging materials suppliers; the tape width ranges between 30 mm (models for small boxes) and 70 mm (the FX5050 model for large boxes), ensuring correct adhesion on corrugated and micro-corrugated cardboard surfaces.

• 240W power consumption: the lowest consumption in its class. The KPW-FX carton sealing machine operates with a motor of only 240W at 220V/110V single-phase; the low consumption means the equipment does not require dedicated electrical circuits and can be connected to any standard outlet available in the hall or warehouse, without additional investment in electrical infrastructure.

• Simultaneous top and bottom sealing: a single pass, box fully closed. The KPW-FX carton sealing machine applies adhesive tape to the upper and lower closing seam of the box in a single pass through the equipment; the box enters open at the ends and exits fully sealed on both faces, ready for labeling, strapping or palletizing, without any intermediate operation.

• Quick box height adjustment: format change without tools. The KPW-FX carton sealing machine allows the upper conveyor height to be adjusted via a quick manual mechanism; switching from tall boxes to low boxes is done in a few seconds, without lengthy line stops and without a technician's intervention; the operator turns the adjustment handle until the upper guides touch the box flap and can resume production immediately.

• 220V/110V, 50/60Hz: compatible with any electrical network. The KPW-FX carton sealing machine operates at both the standard European voltage of 220V/50Hz and at 110V/60Hz, without additional transformers; the dual voltage and frequency compatibility makes it usable in any hall configuration, including spaces with mixed electrical infrastructure.

Technical Specifications: The Five Models of the KPW-FX Carton Sealing Machine

Model Selection Guide: The KPW-FX Carton Sealing Machine Right for Your Flow

The KPW-FX carton sealing machine is available in five configurations with partially overlapping size ranges, but with distinct characteristics that make them suitable for different types of boxes and applications:

• KPW-FX4030: for small and narrow boxes (width 80–300 mm, height 90–400 mm). The FX4030 carton sealing machine is the most compact in the series and is aimed at operators who seal exclusively small boxes; the smaller footprint of the equipment is an advantage in narrow packaging spaces where every square meter counts; the 30/45/48 mm tape ensures solid sealing on light and medium boxes.

• KPW-FX4050: for low boxes with large width (minimum height 40 mm, width up to 500 mm). The FX4050 carton sealing machine has the lowest minimum accepted height in the series (40 mm), useful for flat boxes with thin products: books, documents, flat cosmetic products, boards or panels; the large width of up to 500 mm allows it to process standard-sized horizontal boxes as well.

• KPW-FX5050 and KPW-FX5050X: broad general purpose (width 80/120–500 mm, height up to 500 mm). The FX5050 carton sealing machine and the X variant are the general-purpose models in the series, suitable for the varied box ranges in e-commerce, distribution and production warehouses; the difference between the FX5050 and FX5050X lies in the minimum accepted width (120 mm vs. 80 mm) and the available tape widths; the FX5050 accepts wider tapes, up to 70 mm, for more robust sealing on heavy boxes.

• KPW-FX6050: for tall boxes (height up to 600 mm, width 130–500 mm). The FX6050 carton sealing machine is the only model in the series that accepts boxes with a height of up to 600 mm; it is aimed at manufacturers and distributors of tall products: household appliances, industrial equipment in tall boxes, furniture or sports products; it is the correct choice whenever the other models cannot process the box because of its height.

Applications: Where the KPW-FX Carton Sealing Machine Works

• E-commerce and fulfillment warehouses: high volume of diverse boxes. The KPW-FX carton sealing machine is most frequently installed in fulfillment centers and e-commerce warehouses where hundreds or thousands of boxes with variable dimensions are sealed daily; the capacity of 1.000 boxes per hour and the quick height adjustment allow several box formats to be processed on the same equipment during the same working day.

• Manufacturers with a final packaging line: the KPW-FX carton sealing machine integrates at the end of the production line, after the operations of filling and manual or automatic closing of the flaps; products enter boxes on the production line, the boxes are fed onto the conveyor and exit sealed, ready for labeling or palletizing, without a manual sealing station.

• Distributors and importers with medium-high volume: the KPW-FX carton sealing machine is also accessible to operators with volumes of 200–500 boxes per day who want to eliminate manual sealing with the tape gun; the 240W consumption and connection to 220V single-phase mean the equipment is installed without additional investment in infrastructure.

• Food industry: cardboard boxes with dry products. The KPW-FX carton sealing machine seals corrugated and micro-corrugated cardboard boxes frequently used in the food industry for dry products, canned goods, canned beverages and other goods that do not require special humidity or temperature conditions during sealing; the standard adhesive tape is compatible with the hygiene requirements of food warehouses.

• Pharmaceuticals and cosmetics: neat sealing on small boxes. The FX4030 and FX4050 carton sealing machines are suitable for small boxes in pharmaceuticals and cosmetics where the appearance of the applied tape matters for the presentation of the product on the shelf; automatic sealing ensures a uniformly applied tape, without folds or bubbles, unlike manual sealing with the tape gun.

• Printing houses and publishers: boxes with books, catalogs, magazines. The FX4050 carton sealing machine, with a minimum height of 40 mm, also processes flat boxes with books or publications; large print runs with hundreds of identical boxes are sealed quickly without monopolizing an operator at the manual sealing station.

The KPW-FX Carton Sealing Machine versus Manual Sealing: A Direct Comparison

The KPW-FX carton sealing machine eliminates all the disadvantages of manual sealing with the tape gun or with hand-applied tape that operators in warehouses and packaging lines encounter daily:

• 100% uniformity vs. human variability: the KPW-FX carton sealing machine applies the tape at the same length, with the same tension and in the same position on every box, regardless of the operator feeding the equipment; manual sealing produces tapes of different lengths, applied crookedly or with insufficient overlap, which generate complaints from recipients.

• 1.000 boxes/hour vs. 200–300 boxes/hour manually: an experienced operator can manually seal at most 200–300 boxes per hour with the tape gun, under optimal conditions and without breaks; the KPW-FX carton sealing machine processes 1.000 boxes per hour consistently, with a single operator who feeds and collects the boxes.

• Zero fatigue vs. high physical strain: the repetitive manual sealing of hundreds of boxes per day generates musculoskeletal problems in operators (shoulder, wrist, back); the KPW-FX carton sealing machine eliminates this physical strain and reduces workplace injuries and absenteeism on the packaging line.

• Controlled tape consumption vs. waste in manual sealing: the KPW-FX carton sealing machine applies exactly the programmed length of tape on each box; manual sealing frequently consumes extra tape through excessive overlaps or by applying a second layer out of uncertainty; the control of tape consumption reduces the material cost per box.

Frequently Asked Questions about the KPW-FX Carton Sealing Machine

What type of adhesive tape does the KPW-FX carton sealing machine use?

The KPW-FX carton sealing machine uses standard rolls of packaging adhesive tape, OPP (biaxially oriented polypropylene) with acrylic or hot-melt adhesive, available from all local packaging consumables suppliers; there are no source constraints or proprietary formats; the roll width must match the configuration of the chosen model (30, 36, 45, 48, 60 or 70 mm depending on the model).

How is the KPW-FX carton sealing machine adjusted for boxes of different heights?

The KPW-FX carton sealing machine has a manual height adjustment system for the upper conveyor, operated via a handle or adjustment wheel without tools; the operator adjusts the height until the upper guides apply the correct pressure on the box flap and can resume production in a few seconds; the box width adjustment is made via the side guides of the lower conveyor.

Can the KPW-FX carton sealing machine work in line with other packaging equipment?

The KPW-FX carton sealing machine is designed for integration into packaging lines; the input and output conveyors allow connection to filling, weighing, labeling or strapping equipment that precedes or follows sealing; UZINEX offers consultancy for configuring the complete packaging flow.

What happens if the tape roll runs out during production?

The KPW-FX carton sealing machine signals the depletion of the tape roll and automatically stops the sealing cycle; replacing the roll is done in a few seconds without tools, via the standard adhesive tape roll mounting mechanism; keeping a stock of spare rolls on the line is recommended to minimize production interruptions.
