What are the differences between polypropylene and polyethylene and which one is right for my project?

Simply stated, both are great cost effective products, with polyethylene the most durable, opaque and less costly. Both can be used as a complete tuck tab or sonic welded for a finished, assembled feel.

Depending on your budget or project, polypropylene or polyethylene are widely accepted as today’s “IT” answer to presentation packaging and long term durability; whether it be boxes, ring binders or folders, Petra and poly go hand in hand!

 

High density polyethylene and polypropylene are almost indestructible materials which are unaffected by water and most chemicals and acids. This combination of durability and liquid resistance makes poly an exceptional material for looseleaf or box products. Our poly is corona treated on both sides so that it can be silk screened or foil stamped. Poly can also be debossed and foil stamped. With the proper combinations of processes and inks, the imprint on poly will present a cost effective yet durable and elegant presentation.
