Compliance & Safety Features to Request in a VFFS Machine

Compliance & Safety Features to Request in a VFFS Machine

Why safety and regulatory compliance matter for your vertical packaging machine

When sourcing a vertical packaging machine — commonly described as a vertical packaging machine or VFFS (vertical form fill seal) — safety and compliance are not optional. They protect workers, reduce downtime, avoid costly recalls, and preserve regulatory approvals for food, pharmaceutical, and consumer goods. The right compliance features reduce legal risk and improve operational uptime and product quality.

Product snapshot: Economic vertical form fill seal packing machine (VFFS)

The economical 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.

Key legal and regulatory frameworks to consider for any vertical packaging machine

Before specifying machine features, understand the frameworks that influence design and documentation:

• Machine safety directives and standards (e.g., EU Machinery Directive, CE marking requirements).
• International standards for machine safety and risk reduction (ISO 12100; ISO 13849 for safety-related parts of control systems).
• Electrical and electromagnetic compatibility regulations (e.g., IEC/EN standards, UL/CSA for North America).
• Food safety and hygienic design rules for materials contacting food (FDA, FSMA in the U.S.; EU food contact regulations).
• Local occupational safety and health regulations (OSHA in the U.S., local labor safety agencies elsewhere).

Essential physical safety features to request in an Economic VFFS

Physical safety elements prevent direct human contact with hazardous zones and reduce the chance of accidental injury or contamination. For the Economic vertical form fill seal packing machine (VFFS), insist on:

• Interlocked guards and safety doors: Doors on access panels should be interlocked so the machine cannot run when open. These should meet relevant PL (Performance Level) or SIL requirements depending on your risk assessment.
• Emergency stop (E-stop) stations: Redundant, tamper-proof E-stops placed at operator and maintenance positions. Ensure they are to EN ISO 13850/IEC 60204 standards.
• Non-contact safety devices: Light curtains or area scanners where guards aren’t practical (e.g., in-feed and discharge areas). These reduce nuisance trips and maintain protection for repetitive operations.
• Fixed guards and physical barriers: Mesh or plate guards for moving components (film rollers, sealing bars, gearboxes).
• Lock-out / tag-out (LOTO) points: Clear LOTO capability for electrical isolation and energy dissipation to support safe servicing.

Control and electrical safety requirements

Control systems must protect against unexpected motion, electrical faults, and software failures. Request the following:

• Safety-rated control architecture: Safety PLC or safety relay modules for E-stop, door interlocks, and light curtain signals, designed to an appropriate SIL/PL level.
• Grounding, short-circuit and overcurrent protection: Labeled, accessible circuit protection and verified grounding to reduce fire/electrocution risk.
• EMC shielding and filtering: To prevent control interference in noisy industrial environments.
• Clear wiring and documentation: Schematics, terminal labels, and a single-point-of-truth electrical manual for serviceability.

Food safety and hygienic design for packaging products

For food, frozen, and other contamination-sensitive products, hygienic design is critical:

• Food-grade materials: The Economic VFFS uses 304 stainless steel — request verification that all product-contact components meet food-contact standards and are corrosion-resistant.
• Sanitary construction: Rounded corners, minimal horizontal surfaces, and sloped frames to avoid water pooling and allow easy cleaning.
• Sealed motors and gearboxes: Motors and other drives should be IP-rated to prevent ingress and allow washdown where required.
• Cleanability and access: Guards and panels that are easy to remove without tools for washdown and inspection.
• Allergen and cross-contamination controls: Design options for quick changeovers and clean separation where multiple products are packaged on the same line.

Operational safety and human-machine interface (HMI)

The machine operator experience affects safety and productivity. Key features to request:

• Intuitive HMI with safety functions: Clear fault messages, guided troubleshooting, password protection for critical settings, and step-by-step shutdown/startup procedures.
• Training and documentation: Operator manuals, maintenance procedures, and on-site training packages from the supplier.
• Visual and audible alarms: For film faults, jam detection, low film, or unsafe conditions so operators respond quickly.
• Ergonomics: Heights, control placements, and access that reduce operator strain and manual handling risk.

Product handling and detection systems

Protect product quality and reduce waste with sensing and verification features:

• Film run detection and web guides: Automatic run-stop on film misalignment to prevent wasted film and sealing errors.
• Bag presence and seal inspection sensors: Verify seals and reject unsealed bags automatically.
• Overfill/underfill detection: Integration with check weighers or multihead weighers to ensure correct net weight and compliance with trade laws.
• Jam detection and safe restart protocols: Automatic detection with safe restart requiring reset after removing the hazard.

Integrating multihead weighers with the VFFS: safety considerations

When pairing a multihead weigher with the Economic vertical form fill seal packing machine, coordinate safety across both machines:

• Safety communication: Hardwired safety signals or safety fieldbus linking E-stops, door interlocks, and light curtains across both units so either machine’s fault stops the line.
• Guarding continuity: Guards should form continuous protection when the weigher and VFFS are adjacent. Do not leave unprotected gaps where operators could reach in between machines.
• Synchronized lockouts: LOTO procedures that isolate both machines simultaneously during service.
• Conveyor and transfer design: Gentle transfer design to avoid product bridging that can cause blockages and unsafe clearing procedures.

Maintenance, diagnostics and risk management

Request features that make safety durable and verifiable over the machine’s life:

• Built-in diagnostics and event logs: Time-stamped fault logs and maintenance reminders help demonstrate due diligence and speed troubleshooting.
• Spare parts strategy: Availability of critical safety spares (interlocks, light curtain emitters/receivers, safety relays) and clear part numbers in documentation.
• Risk assessment package: A supplier-provided risk assessment (per ISO 12100) and a machine-specific instruction manual describing foreseeable misuse and mitigation measures.
• Planned preventive and predictive maintenance: Schedule for verifying safety devices, lubrication, and electrical checks to reduce degradation-related failures.

How to verify compliance at purchase and during installation

Buying a compliant machine requires objective evidence. Ask for:

• Certificates and conformity documents: CE Declaration of Conformity (EU), UL/cUL listings (North America), and any regional approvals required for your market.
• Factory Acceptance Test (FAT): A documented FAT demonstrating safety functions, interlocks, and emergency stops work under simulated conditions.
• Site Acceptance Test (SAT) / IQ-OQ procedures: Installation Qualification and Operational Qualification scripts to prove the machine operates safely in your environment.
• Machine file and technical documentation: Electrical drawings, parts list, software versions, risk assessment, and instruction manuals in your language.
