What is a Compostable Package?
A compostable package is made of materials that break down under certain conditions, including heat, oxygen, humidity, and the presence of microorganisms. Our compostable closures are made using certified materials, such as vegetable oil, sugar cane, stover, straw, dent corn, and hemp, and have been successfully qualified with bio-based films as a pouch on converting equipment.*
Market support of packaging made from these resins allows packagers to utilize renewable resources and produce high performing products designed to be kept out of the landfill, and returned to the soil.

Is a Compostable Pouch the Right Package For You?
Compostable materials can perform well with many applications, but are ideal for food based, non-toxic products that don’t require high barrier requirements or extra long shelf life. Our team and network of pouch converters can help you decide if compostables would be a good fit for your sustainable package.
The Fresh-Lock team works to ensure each compostable closure is compatible with emerging sustainable film technology while still delivering the ideal consumer experience for reclosable pouches.
The most prominent certification body in the U.S. is the Biodegradable Products Institute (BPI), and the primary specification associated with the compostability of a package is ASTM D6400. The BPI is the only third-party verification of ASTM standards for compostable products in North America. Its Certification Mark indicates verification of compostability for manufactures and brand owners to use on products and packaging.
There are organizations outside of North America that also provide compostable packaging certification. TÜV AUSTRIA offers industrial as well as home compost certifications for packaging.
