Corrugated paper is versatile and practical for packing, mailing, moving, and DIY projects. On this page, you’ll find flat corrugated sheets (often called layer pads or inserts) and single-face rolls for different tasks.

• Shipping & mailing: Slide flat pads into mailers to stiffen envelopes or separate items in a box.
• Packing & moving: Wrap items with single-face rolls (like B-flute) to add cushioning and reduce scuffs.
• Storage & organizing: Line boxes or place sheets between stacked items for added protection.
• DIY crafts & school projects: Use colorful corrugated sheets for textured art, models, and signage.

Choosing between rolls and sheets depends on your item’s shape and the level of cushioning you prefer.

Corrugated paper typically refers to paperboard that includes a wavy, fluted middle layer bonded to one or two flat liners. That fluted profile helps add strength and cushioning without a lot of weight.

• Single-face rolls: One flat liner attached to a fluted layer, flexible for wrapping irregular items.
• Flat pads/sheets: Cut pieces made from corrugated board, used as inserts or layer pads in boxes and mailers.
• Thickness options: You’ll see flute types (like B-flute, about 1/8" thick) and metric thicknesses (around 2–3 mm) noted in product details.

On this page, both rolls and sheets show how corrugated construction can help with cushioning, layering, and craft projects, depending on your needs.

People often use “cardboard” as a catch‑all term, but corrugated usually means a board with a fluted (wavy) inner layer for added strength. Flat cardstock or chipboard has no flutes and is a single, solid sheet.

• Corrugated products: Include single‑face rolls and layer pads that provide cushioning and rigidity for packing and mailing.
• Flat boards: Better suited for lightweight backing, simple craft pieces, or signage where cushioning isn’t needed.
• Selection tip: For protection inside boxes or mailers, corrugated rolls and pads can help add structure. For thin, smooth surfaces in craft work, a flat board may be sufficient.

The right choice depends on whether you want cushioning and strength or a thinner, flatter profile.

A corrugated sheet is a flat piece of corrugated board used for layering, separating, and reinforcing. On this page, you’ll see them listed as pads, inserts, or layer pads in various square and rectangular sizes.

• Protection in boxes: Place between product layers to distribute weight and reduce scuffs.
• Mailer support: Add to envelopes to help keep documents or photos flatter in transit.
• Project material: Cut to size for DIY, school displays, or lightweight structural models.
• Strength info: Some sheets include ratings (e.g., ECT‑32) that describe edge‑crush performance for stacking contexts.

Pair sizes to your packaging or craft dimensions to minimize trimming and waste.

Choose based on your item’s shape and how you plan to pack or craft.

• Use rolls (single‑face): Flexible B‑flute or similar rolls conform around bottles, frames, and odd shapes, offering cushioning and scuff protection.
• Use sheets (pads/inserts): Pre‑cut pieces are handy for flat layering inside boxes, stiffening mailers, or making clean craft cutouts.
• Size & storage: Rolls cover long or varied lengths without seams; sheets store flat and are easy to batch-use.
• Thickness notes: Thicker profiles can add more cushioning; thinner options suit detail work.

If your tasks mix wrapping and layering, combining a roll for wrap and sheets for separators can be a practical approach.
