Flipside Products 32" x 40" Kraft Two Sided (E-Flute) Corrugated Project Sheets, Cardboard Sheets, Flat Packing Inserts, Crafts, Pads Packing, Brown, Pack of 25

What I Liked: These corrugated cardboard sheets are sturdy, cleanly cut, and versatile. The E-flute thickness provides a nice balance between flexibility and durability, making them useful for a variety of projects. My Experience: The sheets arrived flat and packaged well, which helped prevent bending or damage. We used them primarily for activities in our children’s church, and they worked great for crafts, displays, and general project use. They were easy to cut and handle, yet strong enough to hold their shape during use. Bottom Line: A reliable pack of cardboard sheets that can be used for crafts, classroom projects, packing inserts, or displays. Simple, functional, and effective for group or organizational use.

I got these cardboard sheets, a.k.a. KRAFT sheets for our involvement with the PTA. They’re perfect for last-minute signs to place at the school. I used one today to make a sign for the side of a Box truck where parents were supposed to drop off donations. The sign needed to be big and it needed to stand out the brown against the white side of the box truck with the black and red paint on it works perfectly. The size is big, but not so big that you can’t lay it in the back of a compact SUV. The cardboard is thick enough that it holds the shape pretty well, it does have a little bit of a curve to it that I think it picked up in the warehouse. In any case, it’s a clean big sheet of cardboard that you can use for projects or signs without worrying about old glue, tape or rips

My fishing friend and I ordered this 10 pack of 32” x 40” cardboard specifically to help upgrade our street signage for local seafood sales. We also saw the potential of this cardboard providing additional reinforcement for some of our neon signage that was painted on thin poster board. The cardboard was packaged and shipped carefully in a cardboard box that was more sturdy than the cardboard inside the box. The sheets of cardboard are well made, with a monotone matte brown finish, but they were strikingly thin, I believe to be about 1/16” thick. I do admit that they were quite easy to cut to a desired size with a standard box cutter or pocket knife. Given its current price, I thought this cardboard would have some extraordinary qualities… such as being exceptionally thick and sturdy, but we unfortunately did not find this cardboard to hold up to this basic standard. My friend and I made a demo seafood sign on two of the cardboard sheets, and it worked out well, though we really could not find anything special about this cardboard for its “high end” price point. We quickly came to realize that this board is too thin for extensive outdoor display, and we had to resort to double-sheet reinforcement. Honestly, my fishing friend could have sourced this cardboard from existing restaurant shipping boxes, or we could have picked up similar cardboard at the local hardware store for a fifth of the price. I came to realize that this cardboard package is catered more specifically to the high-end arts and crafts industries, where certain artists and art framers would need specific, sterile, and immaculate sizes of cardboard to reinforce their exquisite masterpieces. In our local seafood rough-&-tumble “dirty jobs” scenario, we simply needed some affordable and hefty street signage and packing reinforcement that is designed to get beat up and destroyed. I am giving this product four stars because I do not find the value in this product for its current high-end “posh price.” I can see this product as appealing to elite artists and crafters who are precise about the presentation and delivery of their posh products; but for down-and-dirty projects, I would otherwise recommend using resourceful wit to find equivalent—and even thicker—cardboard at a much more affordable price.

Thinner than i expected and about 1/4 of an inch short on each side. Came with a slight crease off center but I think that was not in the sellers control. Other than that, they are exactly as described and sturdy.

I absolutely love this 10-pack of large cardboard sheets! The 32" x 40" size is generous, making them incredibly versatile for so many uses around my home and business. I primarily use them as flat packing inserts for shipping large artwork, and the E-Flute corrugated material is sturdy enough to prevent bending and damage during transit, which is a massive relief. The fact that they are two-sided Kraft (brown) gives them a clean, natural look perfect for crafts or mounting projects. They also stack neatly without warping, so storing the unused sheets is simple. This is an excellent bulk purchase of high-quality, flat cardboard that is far more rigid and reliable than what you find at a standard craft store.

These Flipside 32" x 40" E-Flute sheets are sturdy, versatile, and perfect for crafts or DIY projects. They are slightly thinner than I expected, but still work well for my purposes—I even made three cat houses with them! The two-sided design is convenient, and the pack of 10 offers great value.

I'm always in need of sheet cardboard: cutting boards, signs, lots of things and it's hard to find. I thought I had found it here but I didn't know how thick (or thin) it was. Apparently, the E-Flute (what I ordered is the thinner stuff that's kind of floppy and the C-Flute I expect is the thicker one. Oh well. How thick is the E-Flute? It's about 2mm, maybe the thickness of two poster boards and while is not as floppy, it's still not completely rigid. I'm sure I'll find things to do with it- lining tables, posters/reinforced signs, something. So, the moral of the story: E-Flute is thin, C-Flute looks thicker. Be nice if they gave that information in the listing.

These project sheets are thick enough to stand on their own and provide a solid surface for mounting or writing. Being double-sided adds flexibility, and the kraft finish gives them a neutral look that works for school, office, or craft use. They are bulkier than standard poster boards, which makes them more durable but also a bit harder to cut cleanly. A practical choice when a stronger display surface is needed.
