You’ll find a wide range of flat corrugated cardboard sheets on Walmart.com. We carry small pads for mailers and oversized panels suited for layering in moving boxes, packing, and craft backdrops.

• Search by size: Try terms like “corrugated cardboard sheets 22x22” or “24x24 cardboard pads” to surface larger options.
• Check pack counts: Listings range from small bundles to bulk packs, which can be helpful for frequent shipping.
• Look at thickness: Bigger items often benefit from thicker or multiple pads for added rigidity.
• Convenient fulfillment: Delivery and store pickup options may be available depending on your location and inventory.

Flat cardboard sheets are corrugated fiberboard panels cut without box folds or scores. They’re commonly used as inserts, dividers, and layer pads for shipping and mailing, and they’re great for DIY crafts, signage, and backing prints or photos.

• Structure: Most options here are single-wall corrugated with a fluted core for stiffness.
• Thickness: You’ll see measurements like about 1/16" or 1/8" (often listed in millimeters), and some sheets note edge-crush ratings.
• Formats: Choose flat pads for rigidity; flexible corrugated rolls are available for wrapping and cushioning.
• Surfaces: Kraft brown, white, and colored finishes offer different looks for crafts and presentations.

On Walmart.com, browse the flat cardboard sheets category and look for listings that highlight thinner profiles. Product titles and descriptions often call out thickness in millimeters (for example, around 1.8 mm) or fractions of an inch (like roughly 1/16" or 3/32").

• Check specs: Look for terms like “lightweight” or specific thickness measurements.
• Use case fit: Thin pads work well as mailer inserts for photos, prints, or trading cards.
• Consider rolls: If you need more flexibility than a pad, single-face corrugated rolls can help with light wrapping.
• Fulfillment: Delivery or store pickup may be available based on your area.

Start by measuring the inside dimensions of your mailer or box. Then pick a sheet that fits comfortably without bulging.

• Match the fit: For a snug insert, choose a sheet equal to or slightly smaller than the inner width and height.
• Common sizes: Many options come in 4x6, 5x7, 8.5x11, 9x12, 11x14, 12x12, and larger square or rectangular formats.
• Rigidity needs: For delicate items, layering two thin pads can add stiffness without switching to a thicker sheet.
• Weight awareness: If you’re mailing, keep overall weight in mind to help manage postage.

Yes, flat corrugated sheets can typically be trimmed to fit your project. The approach depends on the thickness and precision you need.

• For clean edges: Use a straightedge and a craft knife on a cutting mat, making several light passes.
• For thinner pads: A sturdy paper trimmer can work for small cuts; heavy-duty scissors may help with simple trims.
• Maintain strength: Cut with the flutes to reduce edge crush, and avoid over-bending to preserve rigidity.
• Plan your layout: Map your cuts to minimize waste and save offcuts for smaller dividers or spacers.
