Packaging

At hyusonic, we specialize in FDA-compliant ultrasonic welding systems designed specifically for food and cosmetic packaging applications. Our advanced technology delivers airtight, contamination-free seals while meeting the most stringent industry standards for safety and quality.

Ultrasonic welding is applicable for joining thermoplastic packaging materials in daily use, composite plastic films, tubular end seals, and hermetic sealing of metal foils with plastic packages. Ultrasonic plastic welding enables excellent airtight and watertight seals, extending the shelf life of packaged products while minimizing chemical oxidation. With the advancement of packaging technology, this technique is also ideal for applications requiring both hermetic sealing and consumer-friendly opening features (e.g., coffee capsules).

Milk Cartons (Paper-Based Composite Packaging)

  1. Sterile Cold Welding Process
    • No heating required (welding temperature <60°C), preventing carbonization of paper substrate or decomposition of PE coating, preserving nutritional activity of milk (e.g., vitamin B12 loss rate <5%, 15% better than heat sealing process).
    • Debris-free and adhesive-free welding, complying with FDA microbial control standards for dairy packaging.
  2. Multi-Layer Composite Sealing
    • Molecular-level bonding of paper/foil/PE triple layers, with weld tensile strength ≥25N/15mm.
    • Ultrasonic vibration penetrates paper to form micro-bonds in aluminum foil, blocking oxygen (permeation rate <0.1cc/day) and extending milk shelf life to >180 days.
  3. High-Speed Mass Production Adaptability
    • Fast single-seam welding time, enhancing production line efficiency with 40% lower energy consumption than thermal sealing.

Flexible Packaging (Food Film Bags, Stand-Up Pouches)

  1. High-Barrier Sealing
    • Continuous pore-free sealing for PE/PA/foil composite films, with water vapor permeability <0.5g/day, suitable for moisture-proof packaging of nuts and freeze-dried foods.
    • Welding preserves EVOH barrier layer, with oxygen permeability <0.1cc/day, maintaining aroma components in coffee/tea (e.g., caffeine retention rate >98%).
  2. Complex Structure Adaptability
    • High-precision welding of stand-up pouch bottom folds to avoid stress cracking at right angles.
    • Welding of irregular pouches (e.g., octagonal bags) via multi-axis robotic arms, with weld uniformity error <5%.
  3. Environmental Protection & Efficiency Balance
    • Solvent-free adhesive, zero VOC emissions, compliant with EU Packaging Directive 94/62/EC.
    • Integrated welding-cutting process at 15m/min, 3x faster than traditional thermal cutting, with burr-free edges.

Instant Coffee Capsules (Aluminum-Plastic Packaging)

  1. High-Airtight Aroma Preservation
    • Capsule top weld leakage rate <0.01cc/min, maintaining coffee aroma retention >95%.
    • Welding preserves silicone gasket elasticity, preventing high-pressure steam leakage during brewing.
  2. Precision Welding Process
    • Ultrasonic energy penetrates aluminum foil to bond with PP base, forming pinhole-free welds.
  3. Full-Proof Oxidation Prevention
    • Post-welding oxygen content <0.3%, extending instant coffee shelf life to 24 months with inert gas flushing.

Fruit Infuser Pots (Plastic Containers)

  1. Structural Strength & Sealing
    • 2m drop resistance (concrete surface) with crack-free welds.
    • Leak-proof under 0.2MPa water pressure testing for beverage infusing.
  2. Aesthetic Welding for Transparent Parts
    • No yellowing or fogging on PET/PC materials, maintaining light transmittance >90%.
    • Weld surface roughness Ra <0.8μm, meeting high-end kitchenware standards.

Personal Care Product Packaging (Tubes, Caps, Pumps)

  1. Hygienic Welding Standards
    • Debris-free tube tail welding.
    • 0.1MPa airtightness for pump-body welding, preventing leakage of shampoos/body washes.
  2. Environmental & Cost Optimization
    • Replaces solvent adhesives, reducing VOC emissions.
    • 80-100 pieces/min welding speed, 5x faster than adhesive curing, cutting labor costs by 30%.
