Polypropylene is used in a number of different packages. While
Flexpak promotes Polyethylene based products, some customer prefer
polypropylene in woven wrap material for lumber, beams, and other wood
While Flexpak recommends woven polyethylene wrap for lumber and wood
products, the sales department will work with customers to provide the
necessary product (design and poly) to meet their needs.
Woven Polypropylene Wrap is used by a few customers in the United States
for lumber and wood products. The PP wrap is often characterized as
having a more brittle feel. In fact, polypropylene is “harder” and more
brittle due to the process in making this poly. While it has aesthetic
values, polypropylene wrap fails in a few comparative areas to
polyethylene woven wrap.
The brittleness of polypropylene wrap makes it difficult for workers
to apply this packaging to a unit of lumber. Often workers have
complained about the difficulty of application compared to a more
flexible polyethylene product. Woven Polyethylene wrap often has a clean
shine “look” in the lumber and wood industries. This same shine can be
found in Polyethylene woven wrap, and if this is an important
characteristic, the coating can be made with a shining poly
characteristic upon request.
Polypropylene wrap has often held a higher price than polyethylene.
This is largely due to two reasons: (1) demand of woven polypropylene
wrap has been much lower than woven polyethylene by mills across North
America. While lower demand usually lowers the price, the demand has
lowered production requirements which limits the supply to North
American customers. And (2) the resin prices often fluctuate to be more
expensive than PE, especially when considering purchasing in lower
quantities due to a lower demand.
