How to Choose a Vertical Packaging Machine for High Throughput

How to Choose a Vertical Packaging Machine for High Throughput

Why choosing the right vertical packaging machine matters

Selecting the correct vertical packaging machine is a decision that directly impacts production throughput, product quality, labor costs, and long-term profitability. Whether you are packing snacks, frozen foods, coffee beans, rice, or small hardware, a machine that matches your throughput needs and product characteristics avoids bottlenecks, reduces waste, and improves shelf appearance. In this guide we use practical criteria and real-world considerations to help you choose the ideal vertical packaging machine for high-throughput operations.

Understand throughput: define your target output with the vertical packaging machine in mind

Begin by defining the throughput you need in finished bags per minute (BPM) or units per hour. Throughput is influenced by bag format, product flowability, target weight consistency, sealing requirements, and operator shifts. Typical categories are:

• Low throughput: < 30 BPM (small runs, niche products)
• Medium throughput: 30–120 BPM (most snack and retail operations)
• High throughput: > 120 BPM (industrial-scale lines, continuous production)

When targeting high throughput, a vertical packaging machine must be selected not only for maximum speed rating but also for consistent reliability at that speed. Peak BPM numbers published by vendors are idealized; practical sustained throughput is lower because of changeovers, product bridging, and upstream/downstream constraints.

Match bag types and sizes to machine capability

A vertical packaging machine supports different bag styles (pillow bags, gusseted, angle-seal, printed bags, triangular bags). Ensure the machine specifies compatibility with the bag formats you need. Bag geometry affects sealing dynamics, film unwind requirements, and film registration (for printed film). A machine optimized for pillow bags may require different forming collars or sealing jaws for triangle or angle-belt bags.

Product handling and dosing: weighers, augers, and compatibility

High throughput requires fast, accurate dosing upstream of your vertical packaging machine. Multihead weighers are commonly paired with VFFS machines for granular products (snacks, nuts, coffee) because they combine speed with accurate portioning. For powders, auger fillers or volumetric cup fillers may be used. Confirm the vertical packaging machine’s infeed interface supports the dosing equipment you plan to use and that there is mechanical and control-level compatibility to synchronize cycle speeds.

Case study: Economic vertical form fill seal packing machine (VFFS)

The Economic vertical form fill seal (VFFS) packaging machine offers a variety of models designed with a sturdy 304 stainless steel frame. It is equipped with safety door protection and supports multiple bag types, including pillow bags, angle belt bags, printed bags, and triangle bags. This versatile machine is ideal for packaging a wide range of materials, such as snacks, frozen foods, coffee beans, oats, sugar, salt, rice, small hardware components, and more. Affordable and cost-effective, it provides reliable performance and efficiency for diverse packaging needs.

Material compatibility and film handling

Consider the types of packaging film (PE, PP, laminated films, metalized films) your packaging requires. For printed films, a reliable film registration system and photo-eye or servo-driven registration are essential for correct print placement. For heat-seal films, confirm the machine’s sealing system—rotary vs. stationary sealing jaws, temperature control precision, and dwell time—can form consistent seals at your target speed. Also check the maximum film roll diameter and unwind tension control; larger rolls reduce downtime and are preferred for high-throughput lines.

Hygiene, materials, and construction for food-grade applications

For food products, prioritize machines built from food-grade materials and hygienic design. The Economic VFFS’s 304 stainless steel frame is standard in food production because it resists corrosion and cleans easily. Look for sanitary frame designs, IP-rated electrical enclosures, and minimal horizontal surfaces to avoid product accumulation. Also confirm cleanable components and ease of disassembly for routine CIP or dry-cleaning processes.

Control systems and automation for consistent high throughput

A modern control system (PLC with HMI) is central to achieving sustained high throughput. Functions to look for include recipe management, speed synchronization, fault diagnostics, and remote access capabilities. Servo-driven film pulling and sealing provide smoother motion, better speed control, and improved bag quality at high BPM. Integration-ready communications (Ethernet/IP, Modbus TCP, Profinet) help the vertical packaging machine connect to upstream weighers and downstream checkweighers or metal detectors for line-wide automation.

Maintenance, uptime, and spare parts strategy

High throughput magnifies the cost of downtime. Choose a vertical packaging machine with widely available spare parts, straightforward preventive maintenance schedules, and accessible components. Ask vendors about mean time between failures (MTBF) data and average response times for local technical support. Spare-part kits for wear items (seals, belts, jaws) and a recommended stock level should be part of procurement planning.

Sealing quality and package integrity at high speeds

At elevated speeds, inadequate sealing can lead to leaks, product loss, and customer returns. Confirm the vertical packaging machine can maintain consistent seal temperature and pressure even at peak BPM. For heat-sensitive products, consider impulse sealing or multiple-stage sealing jaws that reduce product exposure to heat. Quality assurance equipment such as in-line leak testers and visual inspection systems should be integrated for critical products.

Safety, ergonomics, and operator training

Safety interlocks, safety doors, and emergency stops are essential in any production environment. The Economic VFFS includes safety door protection, which helps meet workplace safety requirements and reduces the chance of operator injury. Ergonomics matter too—design elements that make film threading, changeovers, and maintenance easier will shorten downtime and reduce operator fatigue. Invest in operator training and clear SOPs for changeovers and troubleshooting.

Footprint, layout, and scalability

A vertical packaging machine should fit into your floor plan and work well with upstream dosing and downstream conveyors or inspection systems. Consider whether you need a compact footprint for limited space or room for additional modules (labelers, nitrogen flushers, date coders). Scalability is important: can you add another line or upgrade to a higher-speed model with minimal changes to your infrastructure?

Energy consumption and total cost of ownership (TCO)

Tally the machine’s energy consumption, expected uptime, spare part costs, and labor before making a decision. A lower initial purchase price can be offset by higher operating costs or downtime; conversely, an economical model like the Economic VFFS may provide an excellent balance of capital expense and operational efficiency for many businesses. Calculate TCO over a 3–5 year horizon to compare alternatives fairly.

Integration tips: syncing a multihead weigher and a vertical packaging machine

To reach consistent high throughput, the multihead weigher and vertical packaging machine must be synchronized. Key steps include:

• Use a common PLC or high-speed communication protocol to coordinate pick-and-place timing.
• Match the multihead weigher’s discharge pattern to the vertical machine’s fill cycle to avoid overfills or partial fills.
• Implement buffer conveyors or surge hoppers to smooth transient mismatches between upstream and downstream speeds.
• Test with full production runs and representative product to validate sustained BPM and make adjustments to dosing targets and machine timing.

Testing and acceptance: ensure the vertical packaging machine meets SLA

Before final acceptance, require factory acceptance tests (FAT) and site acceptance tests (SAT) that include:

• Sustained run test at target BPM for several hours, using actual product and film.
• Verification of weight accuracy and seal integrity across a representative batch.
• Control integration tests with upstream and downstream equipment.
• Operator training and documentation handover.
