Unilever recognises Enercon for its award winning Hellmann’s Mayonnaise Squeeze Bottle
Its '"clean lock cap" eliminates drips and the precision tip allows for easy control during use along with Selig Group's, Lift 'n' Peel induction liner.
While the new design allows for easy application, it presents challenges when trying to apply an induction seal. The flip-top closure’s foil is recessed from the top of the cap unlike standard applications and the induction seal’s diameter is smaller than the diameter of the cap.
“This was not a one-size-fits-all project”, said Ryan Schuelke, VP, Sales, Enercon Industries, which makes induction cap sealers which are prevent tampering, leaks and preserve freshness with hermetic seals for packagers in the food, beverage and pharmaceutical industry.
“We specialize in engineering sealing heads where the depth of foil is recessed in caps like Unilever’s package. Our engineers were able to optimize the induction field to ensure the required sealing power is efficiently delivered to induction foil. This is critical in producing a consistent hermetic seal.”
The strength of an induction field dissipates as it penetrates the package, so wthout the right sealing head Unilever would have to apply an extreme amount of power and it would inefficiently heat the foil.
Enercon engineers fitted Unilever’s induction sealers with custom sealing heads designed to focus the pattern of the sealing energy to the position of the foil.
"We worked with Enercon Industries to design a bottle to help consumers get the most out of the product, and the most product out of the bottle.” said Tom Wajda, R&D director, Unilever.
