The KPW-QP150 automatic flat labeling machine is the industrial equipment for applying self-adhesive labels onto the flat surfaces of products — cardboard boxes, parcels, packs, trays and any product with a flat surface — at a rate of 120–150 products per minute, with an accuracy of ±1 mm, for products with a length of 50–400 mm, a width of 40–150 mm and a height of up to 150 mm, with labels of maximum 150 × 200 mm, optical detection sensors, a touch panel, a stainless steel body and a weight of 150–180 kg at 220V single-phase.
The KPW-QP150 automatic flat labeling machine is the only labeler in the UZINEX range designed for flat surfaces, unlike the QC160 and BC150 models which label the cylindrical surfaces of vials and bottles; products enter on the adjustable conveyors of the KPW-QP150 automatic flat labeling machine, are detected by optical sensors, and the transfer system applies the label with ±1 mm accuracy onto the flat top or side surface of each product in a fully automatic continuous flow. Key Advantages of the KPW-QP150 Automatic Flat Labeling Machine
• 120–150 products per minute — flat labeling at industrial speed — the KPW-QP150 automatic flat labeling machine applies labels onto flat surfaces at 120–150 products per minute in continuous flow; at the maximum speed of 150 products per minute, the equipment processes 9,000 products per hour — a productivity impossible to achieve through manual or semi-automatic labeling of boxes and parcels with flat surfaces.
• Products L50–400 × W40–150 × H150 mm — full coverage of standard formats — the KPW-QP150 automatic flat labeling machine processes products with a length from 50 to 400 mm, a width from 40 to 150 mm and a height of up to 150 mm; this range covers the standard cardboard boxes used in the food, cosmetic, pharmaceutical and e-commerce industries, from small individual-product boxes (50 × 40 × 30 mm) up to medium shipping boxes (400 × 150 × 150 mm).
• Label max 150 × 200 mm — large format for labels with complete information — the KPW-QP150 automatic flat labeling machine applies labels up to 150 mm wide and up to 200 mm long; the 150 × 200 mm label covers 300 cm² of flat surface, enough for the complete delivery label with address, QR code, barcode, logo and handling information on a single label without segmentation across multiple surfaces.
• Accuracy ±1 mm — exact label alignment on the flat surface — the KPW-QP150 automatic flat labeling machine applies each label in the same position relative to the product edges with ±1 mm accuracy; the accuracy is essential for barcode and QR code labels where deviation from the programmed position produces read errors with logistics or point-of-sale scanners.
• Optical sensors — automatic detection of each product, regardless of spacing on the conveyor — the KPW-QP150 automatic flat labeling machine uses optical sensors that detect the leading edge of each product on the conveyor and automatically synchronize the label application moment with the product position; uneven gaps between products on the conveyor do not affect the label positioning accuracy.
• Adjustable conveyor — quick adaptation to product width — the KPW-QP150 automatic flat labeling machine has side guide conveyors adjustable for product widths from 40 to 150 mm; changing the product format is done by adjusting the guides without special tools; adjusting the height of the labeling head relative to the product surface is done from the control panel for products of different heights in the same batch.
• Touch panel — quick setup and real-time monitoring — the KPW-QP150 automatic flat labeling machine has a touch-panel interface for setting and monitoring the conveyor speed, the label position relative to the product's leading edge, sensor sensitivity and label-out alarms; the parameters are visible in real time and can be adjusted without stopping production.
• Stainless steel and label-out alarm — continuous reliability in intensive production — the KPW-QP150 automatic flat labeling machine has a corrosion-resistant stainless steel body and an automatic alarm system that stops the conveyor when the label roll is depleted or when a jam is detected, preventing unlabeled products from advancing to the downstream packaging or shipping stations.

The KPW-QP150 Automatic Flat Labeling Machine versus the Side Labelers in the Range
The UZINEX range of labeling equipment includes both machines for cylindrical surfaces and the KPW-QP150 automatic flat labeling machine for flat surfaces; the difference is not only technical — it is determined by the shape of the labeled product, and there is no usage overlap between the two types:
• The KPW-QP150 automatic flat labeling machine — for flat surfaces — cardboard boxes, parcels, flat-bottomed bags, container lids, trays, heat-sealable films, envelopes and any product with a flat top or side surface; the label is applied top-down onto the horizontal surface of the product moving on the conveyor.
• The KPW-QC160 and KPW-BC150 side labelers — for cylindrical surfaces — bottles, vials and cylindrical containers with a diameter of 20–120 mm where the label is applied onto the round surface; these models cannot label flat surfaces because the application mechanism is calibrated for cylindrical geometry.
• Combining both types in the same line — products that require both cylindrical-surface labeling (product label on the vial) and flat-surface labeling (delivery label on the shipping box) use both types of equipment in tandem; the KPW-QP150 automatic flat labeling machine labels the shipping box, while the side labelers label the individual vials in the box.
Applications — Which Products the KPW-QP150 Automatic Flat Labeling Machine Labels
• E-commerce and logistics — delivery labels on parcels and shipping boxes — the KPW-QP150 automatic flat labeling machine automatically applies delivery labels (address, QR code, courier barcode) onto the top surface of shipping boxes with a length of 50–400 mm at a rate of 120–150 boxes per minute; over 8 hours of continuous operation, the equipment processes 57,600–72,000 parcels — a capacity attainable only through full automation of the shipping labeling station.
• Food industry — product labels on boxes and trays — the KPW-QP150 automatic flat labeling machine labels boxes of packaged food products, trays of pastry and confectionery products and flat-bottomed bags with identification, expiry and barcode labels; the flat surface of the box or tray is the perfect frame for the product label with brand graphics and the nutritional information required by food regulations.
• Pharmaceutical industry — medicine boxes and medical devices — the KPW-QP150 automatic flat labeling machine labels medicine boxes and medical device boxes with batch identification labels, GS1 barcodes and safety labels; the ±1 mm accuracy is essential for pharmaceutical barcodes where deviation from the standard position produces read errors in the traceability systems of the pharmaceutical chain.
• Cosmetics and perfumery — presentation boxes — the KPW-QP150 automatic flat labeling machine labels the presentation boxes of cosmetic products and perfumes with code, price and barcode labels; flat cosmetic boxes with a width of 40–150 mm and a length of 50–200 mm are processed efficiently at a rate of 120–150 units per minute without per-product intervention.
• Electronics industry — component and accessory boxes — the KPW-QP150 automatic flat labeling machine labels boxes of electronic components, accessories and devices with identification, serial number and barcode labels; automatic labeling of the box's flat surface at 150 products per minute significantly reduces the per-unit labeling cost versus manual methods.
• Distribution and warehousing — inventory labeling on parcels — the KPW-QP150 automatic flat labeling machine applies inventory and location labels onto warehouse parcels and boxes in the receiving or shipping line; integration with WMS (Warehouse Management System) systems by connecting to the label printer upstream of the equipment allows automatic labeling of each parcel with the label generated dynamically from the system.
How the KPW-QP150 Automatic Flat Labeling Machine Works — the Labeling Flow
The KPW-QP150 automatic flat labeling machine processes each product in four fully integrated automatic stages, without manual intervention after startup and the initial parameter setup:
• Stage 1 — Feeding and alignment on the conveyor — products are fed manually or by an upstream conveyor onto the feed belt of the KPW-QP150 automatic flat labeling machine; the adjustable side guides center each product relative to the longitudinal axis of the conveyor, ensuring that the leading edge of the product always passes through the same plane relative to the detection sensor.
• Stage 2 — Optical detection and synchronization — the optical sensor of the KPW-QP150 automatic flat labeling machine detects the leading edge of the product and transmits the signal to start the label application cycle; the control system calculates the exact moment of label release relative to the conveyor speed to ensure application at the set position with ±1 mm accuracy.
• Stage 3 — Label application — the transfer system of the KPW-QP150 automatic flat labeling machine advances the label from the roll, peels it off the silicone backing and applies it onto the flat surface of the moving product; the press roller or application pad ensures complete label adhesion without air bubbles or wrinkles across the entire label surface.
• Stage 4 — Discharge and flow continuation — the labeled product exits onto the discharge conveyor of the KPW-QP150 automatic flat labeling machine ready for secondary packaging, palletizing or direct shipping; the rate of 120–150 products per minute is maintained constant regardless of the duration of the production session.
Frequently Asked Questions about the KPW-QP150 Automatic Flat Labeling Machine
Can the KPW-QP150 automatic flat labeling machine also label the bottom surface (base) of the product?
The KPW-QP150 automatic flat labeling machine in the standard configuration applies the label onto the top surface of the product (top-labeling); for labeling the bottom surface (bottom-labeling) or the flat side surfaces, UZINEX engineers analyze the required labeling head configuration and the availability of the suitable version on request. Can the KPW-QP150 automatic flat labeling machine be connected to a label printer for dynamic labeling?
Yes. The KPW-QP150 automatic flat labeling machine is compatible with the integration of a print-and-apply module where the label is printed dynamically with variable data (address, batch, production date, serial code) and applied immediately onto the product; UZINEX engineers analyze the integration configuration with the client's management system on request. What happens if a product is not centered on the conveyor at the KPW-QP150 automatic flat labeling machine?
The KPW-QP150 automatic flat labeling machine has adjustable side guides that passively center the products on the conveyor; very irregularly shaped products (packaging with sloped edges, products with burrs) may require an additional upstream guide; UZINEX engineers analyze the specific product type and recommend the optimal guiding configuration at commissioning. How long does it take to change the label roll on the KPW-QP150 automatic flat labeling machine?
The KPW-QP150 automatic flat labeling machine allows replacing the empty roll in a few minutes without tools; the start of the new roll is fed through the strip guides and spliced to the end of the finished roll; the label-out alarm signals roll depletion in advance, allowing the spare roll to be prepared before production stops. Why Choose UZINEX for the KPW-QP150 Automatic Flat Labeling Machine
The KPW-QP150 automatic flat labeling machine with ±1 mm accuracy at 150 products per minute requires precise calibration of the optical sensors, of the label feed speed relative to the conveyor speed and of the labeling head height relative to the product surface; these settings are made at commissioning for each product-label combination and are decisive for labeling quality in production.
