Do I need certified recycled poly mailers?
Our standard recycled poly mailers available on this page are consistent in color (ivory or gray), smooth in texture, and have a more premium feel than our RCS100-certified poly mailers. If your brand prefers or requires third-party certification, our RCS100-certified mailers might suit you, but the are only available in a single off-white color with a slight gray tint. Also, they have some texture and gelling inconsistencies and a somewhat brittle feel. Finally, our RCS100-certified poly mailers are slightly more expensive than our standard offering.
To summarize, if RCS certification is important, choose RCS100-certified poly mailers. If cost, texture, or color consistency is most important, choose our standard recycled poly mailers.
