RLAVBL 24×36 Heavy Duty Cardboard Sheets
These sheets are built from a high-quality three-layer E-flute corrugated board, delivering strong protection for shipped items. The 24 x 36 inch size fits many mailers and DIY kits, and the 2 mm thickness adds rigidity without excessive bulk. This option is best for buyers needing sturdy, cost-effective inserts for standard flat items like prints, photos, certificates, or documents.
Who this is best for: small businesses, crafters, and hobbyists who ship or mail larger flat items and want reliable cushioning. Why selected: the three-layer construction provides dependable support while staying reasonably lightweight for bulk packing.
Caution: the sheets are large and may require extra protective packaging when transporting very delicate items. Ensure appropriate handling when mailing fragile materials.
RLAVBL 36×48 Heavy Duty Cardboard Sheets
This larger option uses the same sturdy three-layer E-flute design, now in 36 by 48 inches with a 2 mm thickness. It’s ideal for shipping sizable art, framing projects, or bulk packing needs. The extra surface area reduces the number of seams in tall or broad shipments.
Who this is best for: small to medium businesses moving large prints or canvases and DIY studios with bigger project kits. Why selected: larger panels cut down the number of sheets needed for wide items, saving time and logistics complexity.
Caution: handling and storage require more space due to the sheet size; plan for flat storage to prevent warping if exposed to moisture.
LOTMER 12×16 Inch 80PT Chipboard Sheets
LOTMER supplies twenty 12 x 16 inch chipboard sheets at about 2 mm thick. The heavy duty backing is well-suited for bookbinding, framing, and projects that require solid rigidity. The smooth, flat surface accepts writing, painting, and gluing with clean results.
Who this is best for: crafters and hobbyists needing a compact, sturdy backing for small projects. Why selected: the smooth surface and consistent thickness simplify precise cutting and layout work.
Caution: not ideal for very heavy loads or frequent bending; better for flat backing and protective panels rather than deep protective layers.
Hathoro Single-Wall 36×48″ Cardboard Sheets
These 36 x 48 inch sheets feature a single-wall corrugated design, offering a thinner yet functional option for layer protection, shipping logistics, and multi-item packaging. They’re best when you need dependable padding without excessive bulk.
Who this is best for: warehouse staff and e-commerce shippers who require lightweight, versatile padding. Why selected: the large size provides broad coverage, reducing the number of layers for mid-volume shipments.
Caution: single-wall boards provide less cushioning than double-wall options; avoid using them for heavy, high-value items or multi-layer stacking without additional protection.
BOX USA Double Wall 24×48″ Kraft Sheets
These are double-wall corrugated sheets measuring 24 by 48 inches. They are designed for heavy duty protection and provide substantial cushioning and rigidity for shipping larger, fragile items. The kraft color adds a natural, sturdy look suitable for professional packaging.
Who this is best for: businesses needing robust protection for larger shipments or items with added fragility. Why selected: double-wall construction offers enhanced cushioning and structural integrity for demanding packaging scenarios.
Caution: heavier weight may require stronger packing materials and equipment in some shipping workflows; verify compatibility with your storage and handling processes.

Magicheap provides 25 sheets at 8.5 x 11 inches with a thickness of about 1.8 mm. These sheets are recyclable and suitable for DIY crafts, framing backing, or protecting smaller items during shipping. The compact format supports precise, small-scale projects.
Who this is best for: hobbyists and crafters needing easily manageable sheets for small frames, display pieces, or classroom projects. Why selected: ready-to-use size for quick, creative tasks without extra cutting. Caution: limited size means more seams for larger items; plan accordingly.
PEKGRIL 24×36 Double Wall Cardboard Sheets
This set includes 15 sheets of 24 x 36 inches with double-wall construction and a 3/16″ thickness. The five-layer material provides a sturdy buffer to minimize scratches and impacts during transport and handling. The sheets also suit many DIY and craft applications due to their rigid, smooth surface.
Who this is best for: frequent shippers and serious crafters who need reliable bulk protection for standard-sized items. Why selected: combining a durable build with ample supply makes it ideal for ongoing packaging or creative reuse.
Caution: thicker sheets can add weight; consider weight limits in your shipping plan and storage needs.
Buying Guide
What size should I choose?
Pick sizes that match the largest item you ship often. For art or photos, 24×36 or 36×48 inches often offer good coverage with fewer seams. For small projects, 8.5×11 or 12×16 inches fit neatly into craft workflows.
Single-wall vs. double-wall, which is better?
Double-wall sheets provide superior cushioning and impact resistance, making them better for heavy or fragile items. Single-wall sheets are lighter and adequate for many standard packaging tasks when weight is a concern.
What thickness do I need?
Thicker sheets (around 2 mm or more) offer better rigidity and protection, especially for items that require stable backing or have sharp edges. For simple spacer uses, thinner sheets may suffice.
How should I store cardboard sheets?
Store flat in a dry environment to prevent warping. Keep away from direct sunlight and moisture. If you must stack, place protective sheets between layers to reduce deformation.
What material should I expect?
Most options rely on corrugated three-layer or five-layer designs, with E-flute or similar structures. This provides a balance of rigidity, lightness, and cushioning to protect items during transit and handling.
