Why Kenray + Greener Sealing Jaws?

With over seven decades of sealing expertise, Greener’s sealing jaws are globally recognised as the benchmark in flexible packaging, tailored to meet the unique demands of your machinery, film types, speeds, and product characteristics. One of Greener’s main USP’s has always been its jaw profiles and matching these profiles to particular films for excellent results. This has made Greener the No. 1 supplier of jaws and associated parts.

Through our Partnership, Kenray brings this precision technology to your packaging line, supported by service and technical support teams.

Rotary Jaws

Designed for high-speed vertical and horizontal machines, Greener rotary sealing jaws deliver dependable performance at peak production rates.

Especially effective on snack, confectionery, and other high-throughput applications, these jaws help maintain consistent package quality –  even at elevated speeds.

Greener high speed rotary jaws are the best in the market & allow customers who have high standard KPI’s to achieve these targets with minimal effort.

Flat Jaws

Many standard jaws simply will not seal all films. Leakages and product in seal (PIS) are frequently reported problems. Because of their manufacturing techniques, Greener Corporation can produce their jaw profile that eliminates sealing issues.
