The partnership with Brückner, a global cast extrusion line manufacturer, will also address the demands for improved consumer ease of use and reduced end of life impact when used with optimised equipment.
This agreement is driven by the need to offer a full-service approach to manufacturing lidding films. It entails providing film producers with raw materials, such as resins and adhesives, as well as training on how to optimize equipment settings to produce a direct food contact compliant, BOPET lidding film efficiently and effectively.
To do this, the companies combined Bostik’s knowledge in specialty copolyesters design and formulation with Brückner’s expertise in designing cast extrusion lines. To simplify processes, film producers can coextrude the resins and adhesives to manufacture the film in one pass, which reduces overall energy usage compared to other film production that require multiple steps.
Additionally, the finished film exhibits peelable behaviour that addresses consumer preferences for ease of use as well as seal safety for meat, dual ovenable, produce and fruit fresh cuts packages and more. Moreover, converters can reduce complexities and associated costs, as they do not have to modify the film via a coating process with a seal/peel layer once they receive it.
Finally, as a full PET-based product, the film helps enable a monomaterial package design and can be recycled with PET thermoform trays.
Thanks to this full-service approach, Bostik and Brückner may also provide film producers with training on how to best utilise the equipment, in order to reduce downtime, including associated waste and energy costs, and quickly deliver quality films to converters.
