Crown produces closure technology for PET containers
Food manufacturers can add flexibility to their product packaging portfolio with new metal closures from Crown Holdings Inc. (crowncork.com), the leading supplier of metal packaging products worldwide, that are compatible with polyethylene terephthalate (PET) containers. The new package combination offers considerable weight, efficiency and breakage improvements for both brands and consumers, while maintaining the high quality aesthetic of glass on store shelves.
In the past, metal closures have seen limited use with PET containers due to both technical and aesthetic constraints. The new metal closure / PET container designs are able to maintain a very robust seal without compromising the shape or integrity of the container during the manufacturing process.
