Sustainable Initiatives in Rigid Plastics


New England’s Largest Plastic Box Manufacturer Sets Standards for Renewable Practices


In 2016, Alpha Rho decided to make a change—a change in our sustainability initiatives that will help us become an industry leader for manufacturing companies interested in renewable energy. After completing a rigorous cost benefit analysis, we decided to up the ante on our commitment to the environment and social issues. So, in July of 2016, Alpha Rho became more than just a manufacturer of plastic boxes, we became a producer of solar energy. This transition was made possible by New England Clean Energy, the company that installed 745 Canadian Solar 320-watt panels, with SolarEdge optimizers, on the roof of Alpha Rho’s 36,000-square-foot facility. This new system produces 238.4-kilowatts of power and has truly revolutionized our energy usage.


Rigid Plastic Packaging Versus Flexible Packaging

Select the Packaging that’s Best for Your Product and Your Bottom Line


Choosing the right packaging for your product means sifting through a wide variety of choices–what type of logo to use, what information to place on the label, and, perhaps most importantly, what style of packaging to pick. Flexible plastic packaging has recently gained a lot of attention as an alternative to rigid plastic packaging but both have their pros and cons, and ultimately there's one clear winner based on what best suits your product and industry.
