A clean environment matters to us!


K+K is committed to sustainable practices. We believe in producing 100% biodegradable packaging while adhering to green manufacturing practices. That's why we adhere to the 3 Rs:


Our manufacturing, office, and warehouse areas use computer monitored climate control systems to preserve electricity and maintain a constant environment.

We use energy efficient lighting systems, motion sensor lights, and participate in a volunteer demand response program with our energy provider to provide load information so that they can efficiently distribute power where it is needed most.

Our manufacturing team developed and instituted a quick-change process utilizing large rolls of film to speed the process of changeovers and lessen down time - conserving energy.


We form a large and diverse group of recycled content material and BIO-PET products and PLA as well.  K+K ThermoForming constantly searches for new, environmentally responsible films for testing and forming.

We utilize sustainable types of post-consumer content material whenever possible, including prime APET made with 30% renewable resources and PET made with a minimum of 50% PCR, as used in soda bottles.


Every piece of packaging that we produce is RoHS compliant (Restriction of Hazardous Substances Directive).

We recycle close to 100% of the raw material that is left behind by the manufacturing process, as well as stainless steel, aluminum, corrugated, office supplies. We use all natural or recycled content cleaning products and janitorial supplies as well.
