This page is for informational purposes about our lease or purchase folding machines. Please call 859-630-2694 or email  [email protected] for additional information.

All Sustainable Produce Containers sizes are available a "Kliklok" folding design that allows them to be hand or machine-formed. Kliklok is a proven technology and we have several refurbished Kliklok machines available for lease or purchase that can form up to 45 containers/minute (cpm). The machine costs around $55k and the lease price depends on your volumes. New machines can form up to 75 cpm and heads can be doubled to double output; these new ones cost around $125k.

How it works: Stacks of flat Sustainable Produce Containers are loaded into the machines to be formed. The vacuum pump de-nester pulls the flat boxes down into the machine where the appropriate size forming head plunges the side locks into place. The finished open boxes can be then hand filled or dropped onto a conveyor belt to be machine filled. Closing machines that can apply glue are also available for the Sustainable Produce Container lid to create a tamper-proof seal. Please contact [email protected] for a quote on these machines or for any questions you may have.
