This partnership is driven by the market’s lack of 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, Bostik and Brückner wish to combine Bostik’s know-how in specialty copolyesters design and formulation with Brückner’s expertise in designing cast extrusion lines.
This combination of skills allowed Bostik and Brückner to simplify processes: film producers can now coextrude the resins and adhesives to manufacture the film in one pass, which reduces overall energy usage compared to other film production processes that require multiple steps.
Additionally, the finished film exhibits peelable behavior 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.
