Product Overview

This 15-pack of White Coroplast Twinwall Plastic Sheet offers 15, 18 in. x 24 in. 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, weather proof 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.

can they be cut?

can these be cut easily? If so, what's the easiest tool to use to cut them? and are they sturdy enough to hold something heavy?
Asked by: mia
Best way to cut Twinwall sheet is with a utility knife. The sheet was not designed to support heavy weights.

18 in. x 24 in. x .157 in. White Corrugated Twinwall Thick Plastic Sheets (15-Pack) is rated 4.8 out of 5 by 8.
Rated 5 out of 5 by from 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!

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from exactly what the web site advertized it as Used this material to build an insert for my rabbits play pen, works perfect as expected.

Rated 5 out of 5 by from 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.

Rated 5 out of 5 by from Great!!! I used these sheets to create outdoor holiday decorations. The corrugated sheets stand up to the elements very well. I am very happy with this product. I found this product very easy to work with and it was very durable. I have many ideas for future uses. I will definately be ordering more in the future.

Rated 4 out of 5 by from 3 sq ft is not 3 feet sq LOL Make an assumption you know what happens. Thought I was getting 36" by 36" but got 24" x 18". Now the corrugation runs horizontal instead of vertical so my Halloween ghosts will have to be smaller or tall and narrow if I put two together.. Otherwise, it is the material I needed and other than pricey I love it.

Rated 5 out of 5 by from This product has the best value for the money! The plastic white corrugated sheets were exactly what I needed...I like that I can shape them how I need them. There are 15 sheets to a package, and that is more than enough for what I needed.

Rated 4 out of 5 by from 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.
