The KPW-350X pillow packaging machine is the horizontal flow-wrap equipment with a continuous FFS (Form–Fill–Seal) cycle that produces pillow-type packages from a roll of heat-sealable film — at a rate of 40–90 packages per minute, with a maximum film width of 350 mm, a package length adjustable between 150 and 330 mm, a maximum product height of 60 mm and an electrical consumption of 2,4–3,0 kW at 220V single-phase, with PLC control and an HMI touch screen.
The KPW-350X pillow packaging machine forms the packaging tube directly from the film roll, introduces the product into the tube on an integrated feed belt, seals the tube seam longitudinally and seals the package ends transversally with simultaneous cutting — producing a fully sealed and aesthetic pillow-type package in a single continuous pass, with no intermediate operations and no manual intervention after start-up. It is compatible with OPP/CPP, PE, PET/PE films, multilayer laminates and special heat-sealable paper. Main Advantages of the KPW-350X Pillow Packaging Machine
• 40–90 packages per minute — continuous flow with no stops between packages — the KPW-350X pillow packaging machine works in continuous FFS mode, with no pauses between cycles; at 60 packages per minute, a single machine produces 3.600 packages per hour; at the maximum speed of 90 packages per minute, hourly output reaches 5.400 packages — impossible to match with any other manual or semi-automatic packaging method.
• Rapid package length adjustment from the PLC — format change with no tools — the KPW-350X pillow packaging machine allows the package length (150–330 mm) to be set directly from the PLC interface, with no mechanical adjustments of the cam or the transversal sealing shaft; switching from one package format to another takes a few minutes by entering the new parameters in the HMI and checking the first packages produced.
• Photoelectric print-mark tracking system — exact alignment of the graphics on every package — the KPW-350X pillow packaging machine detects the register mark printed on the printed film and automatically synchronizes the cutting position with the graphics on the packaging; every package comes out with the image centered and symmetrically cut, with no variation from one package to another that would spoil the shelf appearance.
• Compatible with OPP, PE, PET/PE and multilayer laminates — the KPW-350X pillow packaging machine accepts a wide range of heat-sealable packaging materials: OPP/CPP for snacks and dry products, PE for frozen products, PET/PE for food products with an oxygen barrier, and multilayer laminates for applications with increased protection requirements; the film is chosen based on the packaged product and the preservation requirements.
• Integrated feed belt — direct connection to the production line — the KPW-350X pillow packaging machine has the product feed belt included in the standard configuration; products arrive on the belt from the previous production station or from the feeding operator and enter the pillow packaging machine directly with no additional intermediate conveyor; the belt is adaptable to the height of the existing line.
• Sealing temperature and time control — uniform sealing on any film — the KPW-350X pillow packaging machine allows independent temperature setting for the longitudinal seam and for the transversal seal; the precise temperature control ensures a tight seal on films with narrow sealing windows (barrier laminates) and avoids overheating on thin films (OPP 20–30 µm).
• PLC + HMI touch screen — intuitive interface with savable parametric settings — the KPW-350X pillow packaging machine stores the format recipes (package length, temperatures, speed, mark position) in the PLC memory; the operator selects the product recipe from the list and the machine reconfigures itself automatically, with no manual re-entry of all parameters at each product changeover.
• 2,4–3,0 kW at 220V single-phase — low consumption, simple installation — the KPW-350X pillow packaging machine operates at 220V single-phase with a consumption of 2,4–3,0 kW; it requires no dedicated three-phase supply; the energy consumption per package produced is one of the lowest in the class of continuous-flow primary packaging equipment.

What the Pillow Package Is and How the KPW-350X Pillow Packaging Machine Produces It
The pillow pack is the form of primary packaging produced by flow-wrap equipment and is one of the most widespread types of packaging in the food, pharmaceutical and consumer goods industries: a bag with a central longitudinal seam on the back and two transversal seams at the ends, with the appearance of a pillow slightly puffed up relative to the contents. The KPW-350X pillow packaging machine produces this type of packaging in four automatic continuous stages:
• Film tube forming — the film from the roll passes through the forming guide (collar) which folds it into a continuous tube around the product; the KPW-350X pillow packaging machine forms the tube directly on the product as it sits on the feed belt, so the film wraps the product on the move with no separate filling station.
• Longitudinal sealing (back seam) — the overlapping edges of the film are heat-welded by the longitudinal sealing rollers that run continuously along the entire length of the tube; the KPW-350X pillow packaging machine keeps the longitudinal sealing temperature constant at the value set in the PLC, regardless of production speed.
• Transversal sealing and simultaneous cutting — the transversal sealing jaws grip the tube, weld it on both sides of the cutting line and separate the finished package from the continuous tube; the KPW-350X pillow packaging machine produces two transversal seals on each cycle — the closing seam of the previous package and the opening seam of the next package — simultaneously with the cutting.
• Finished package discharge — the sealed package is discharged onto the outfeed belt toward the labeling, weight-check or palletizing station; the KPW-350X pillow packaging machine can be connected to metal detectors, checkweighers and other inspection equipment placed on the discharge belt.
Applications — What Products the KPW-350X Pillow Packaging Machine Packages
• Food industry — snacks, biscuits, wafers, bars — the KPW-350X pillow packaging machine is the standard equipment for packaging dry bakery products, extruded snacks, cereal bars and biscuits; OPP/CPP film provides protection against moisture and an attractive shelf presentation with the printed graphics centered by the photoelectric system of the pillow packaging machine.
• Confectionery and chocolate — pralines, candies, bars — the KPW-350X pillow packaging machine packages individual pralines, candies and chocolate bars in metallized OPP film or PET/PE with a barrier to moisture and fats; the low sealing temperature available on the metallic films protects the heat-sensitive products in the immediate vicinity of the seam.
• Bakery products — portioned bread, rolls, pastries — the KPW-350X pillow packaging machine packages portioned pieces of bread, rolls and pastries in microperforated PE film or transparent OPP film; the maximum product height of 60 mm covers the range of flat and medium-height bakery products.
• Pharmaceutical industry — individual packaging for tablets and devices — the KPW-350X pillow packaging machine, with heat-sealable film compliant with food regulations, packages individual medical devices, rapid tests, single-use kits and other pharmaceutical or cosmetic products with dimensions up to 60 mm in height and 330 mm in length, in a pillow pack.
• Non-food products — components, accessories, toys — the KPW-350X pillow packaging machine produces individual packaging for electronic components, small automotive accessories, individual toys and any rigid or semi-rigid product under 60 mm in height that requires aesthetic primary packaging for shelf presentation or transport protection.
• Cosmetics industry — flat individually packaged products — the KPW-350X pillow packaging machine packages flat face masks, individual cosmetic products and personal-care accessories in flat formats, in a pillow pack; the laminated PET/PE film provides good packaging rigidity and a premium presentation compatible with the requirements of the cosmetics industry.
Film Materials Compatible with the KPW-350X Pillow Packaging Machine
The KPW-350X pillow packaging machine accepts all the main types of heat-sealable film used in the primary packaging industry, each with specific characteristics for different applications and preservation requirements:
• OPP/CPP (biaxially oriented/cast polypropylene) — the most frequently used with the KPW-350X pillow packaging machine; transparent, with high gloss, moisture-resistant, ideal for snacks, biscuits and dry products; available in transparent, metallized and brand-graphics-printed variants.
• PE (polyethylene) — flexible and resistant to low temperatures, used with the KPW-350X pillow packaging machine for frozen or refrigerated products; the microperforated variant provides the breathability needed for fresh bakery products that release moisture.
• PET/PE (polyester–polyethylene laminate) — a laminate with an improved barrier to oxygen and moisture, used with the KPW-350X pillow packaging machine for products with an extended shelf life; superior rigidity compared with plain OPP, premium shelf presentation.
• Multilayer barrier laminates — for applications with high requirements for protection against oxygen, light or water vapor; the KPW-350X pillow packaging machine sets the temperatures independently for each sealing layer to ensure the correct weld on the multilayer structure without damaging the barrier.
• Special heat-sealable paper — for packaging with a paper appearance (eco applications, artisanal products, premium confectionery); the KPW-350X pillow packaging machine works with heat-sealable paper at lower temperatures and pressures than conventional plastic films.
