FAQ
Where can I get large cardboard sheets?
You can shop a wide range of large corrugated cardboard sheets and single-face rolls on Walmart.com. The selection includes flat pads in small, medium, and oversized formats, plus long rectangular panels for banners or dividers. You’ll also find continuous rolls for broader coverage.
- Filter by size: options span from compact 5 x 7 in to larger panels.
- Choose style: flat sheets, layer pads, or single-face rolls.
- Color choices: kraft brown, white, and select colored sheets.
- Pack counts: multipacks for small or bulk needs.
Order for shipping or local pickup where available. Availability, pack sizes, and fulfillment options can vary by location.
What is a sheet of cardboard called?
On our site, you’ll see a few common names:
- Corrugated cardboard sheets/pads: flat pieces used as stiffeners, dividers, or craft bases.
- Layer pads: flat pads often listed with ratings like 200#/ECT-32, commonly used for top layering protection.
- Inserts/filler sheets: pads sized to fit mailers or boxes for added rigidity.
- Single-face corrugated rolls: a continuous sheet for wrapping and surface coverage.
You may also see flute and thickness details (for example, B flute around 1/8 in) and dimensions like 8.5 x 11 in or 12 x 12 in. Use these terms and specs to match the format to your packing or crafting task.
Where can I find cardboard sheets at Walmart?
You can browse corrugated sheets and rolls online in the Office Supplies area. A quick way to find them:
- Search: enter “corrugated cardboard sheets,” “layer pads,” or “single-face roll.”
- Browse: Office Supplies > Shipping Supplies or Mailing Supplies to view the full selection.
- Filter: narrow by size (e.g., 5 x 7 in to larger panels), color (kraft, white, select colors), thickness/flute (including B flute), and pack count.
- Fulfillment: choose shipping or store pickup if available in your area.
Listings often show ratings (e.g., 23 ECT or 200#/ECT-32) and exact dimensions, so you can quickly compare options. Availability can vary by location.
How do I pick the right size and thickness?
A quick approach is to match the sheet to your task, then fine-tune by spec:
- Measure your item or mailer: pick a sheet size that fits inside without bending.
- Choose format: flat pads for stiffeners or dividers; rolls for wrapping curves and edges.
- Check thickness/flute: many pads list B flute (about 1/8 in) or similar (around 1.8 mm). Use the listed ECT ratings to compare sturdiness.
- Size examples: apparel and documents often align with 8 x 10 in or 8.5 x 11 in; larger art or box lining may need 12 x 12 in or bigger.
When in doubt, review dimensions and ratings shown on each listing before you buy.
Are rolls or flat sheets better for packing?
It depends on what you’re packing and how you’ll use it:
- Flat sheets/pads: great as rigid inserts, dividers, or layer pads for top layering protection. They come in set sizes for quick, repeatable packing.
- Single-face rolls: useful for wrapping odd shapes, lining boxes, and adding surface protection. Rolls (for example, around 12 in wide in long lengths) let you cut exactly what you need.
- Consider storage and speed: sheets stack neatly and are fast to deploy; rolls save space and offer flexibility.
Review the dimensions, flute, and any ECT ratings in product listings to choose the format that aligns with your project.
