This 15-pack of White Coroplast Twinwall Plastic Sheet offers 15, 18” x 24” 4mm thick, fluted polypropylene sheets. Corrugated twinwall plastic is strong and durable for many applications and offers a wide range of possible uses around the home, shop, and job site. They are lightweight, weatherproof, and moisture resistant. Twinwall is used in a myriad of applications, from temporary floor protective barriers—protecting hardwood or custom flooring during construction and renovations—to permanent signage. It is used in many protective applications over cardboard due to its toughness (will not tear) and its resistance to moisture (waterproof). Other common applications are: pet cage dividers, dunnage, yard signs, hunting blinds, art projects, and much more.

Rated 4.8 out of 5 by 8 reviewers.
Rated 5.0 out of 5.0 by Easy to cut yet strong - can be used in many applications I have wire shelving in my pantry that was very annoying. Small bottles and cans would topple over unless placed precisely on the shelf. Small items were constantly falling through the shelves. I used these plastic sheets to line my shelving and what a difference it made! No more worries about items falling through and everything sits up straight no matter where it's placed. The corrugated was easy to cut to the desired dimensions with an razor knife and careful measuring. The white translucent material allows some light to pass through so my bottom shelves are not in the dark, even though the top shelves have been covered. I already have plans for the leftovers. Very versatile stuff! January 23, 2013
Rated 5.0 out of 5.0 by Used for Guinea Pigs Cage I used this as the bottom and half sides for my guinea pigs' cage. Very easy to cut and handle. I wish it came in different colors, though. I would have preferred a darker color. May 29, 2014
Rated 5.0 out of 5.0 by exactly what the web site advertized it as Used this material to build an insert for my rabbits play pen, works perfect as expected. July 1, 2012
Rated 5.0 out of 5.0 by Perfect - what I needed This part of my order took it's time coming from DFW, Tex. but once it got here, it was exactly what I wanted for the backing on my photo art when I frame it. 18x24 - exact size I needed. Love the sturdiness - works great in supporting the 18x24 enlargements of my photo art. September 16, 2013
Rated 4.0 out of 5.0 by Durable and handy I ordered this online since stores don't stock it, and it arrived quickly at the store for pick-up. Exactly what I needed for a project. I cut the large sheets into the patterns and the sheets remained sturdy and cleanly trimmed. Only wish that I could've bought a smaller packet, but am sure the extra sheets will be used in a future project. March 12, 2014
