  1. Capless Induction Sealing New sealing technology providing performance improvements, significant cost &weight reduction opportunities and greater design flexibility

  2. Benefits of Capless Induction Sealing • Provides greater control over sealing process • Allows immediate inspection of sealed container • Rubber insert in sealing head delivers better compliance with uneven sealing surfaces than is possible with a cap • Allows cooling of seal under pressure – better performance with hot-fill products • Reduces cap and liner cost Use of new sealing technology provides opportunity for efficiency gains, cleaner production, improved visual appearance of product and enhanced consumer experience with easy to remove foil.

  3. Conventional Conduction Sealing Hot, stainless steel sealing head Heat pattern on sealing head face Pressure & heat Heat conducted into foil cap 210°C Product

  4. Conventional Induction Sealing • Foil lined cap • Cap torque presses foil against neck of bottle • Foil heated through cap using electromagnetic waves • Heat-seal layer melts and bonds foil to bottle

  5. Capless Induction Sealing Ambient temperature sealing head Pressure Heat pattern on foil seal - only sealing area of foil is heated Heat insulation material 230°C Heat induced into foil where required to form the seal 21°C Product

  6. Comparison Between Sealing Systems

  7. Comparison Between Sealing Systems

  8. The Benefits of Capless Induction Sealing Increased Efficiency • Electromagnetic heating within foil, no heat lost into environment • Energy only used when machine sealing, zero consumption on standby Total Control • Real time digital control over induction power level (temperature) • Exact control of induction cycle time • Precise control of pressure with rubber head insert for even conformity • Ability to maintain pressure on foil during ‘cooling’ phase • Measurement of induction power on each seal possible =100% QA validation Improved Productivity • Significant reliability improvements as no heat is present in the components • Instant start-up & shut-down • Fast sealing cycle times • Clean sealing • Greater operator safety with cold sealing head
