ClearBags A - Z Glossary of Packaging Terms

Wednesday, March 29, 2017



We often find that the world of packaging lingo can get a bit confusing. Take complicated names for different materials and mix that in with proprietary ClearBags terms, then add a dash of lengthy acronyms to get the perfect combination of often confusing packaging speak. We wanted to clear up some of those terms with this quick glossary of packaging terms. Hopefully, this helps! Let us know in the comments any additional questions you might have and we will add them to the list.
