Corrugated Cardboard Sheets 20in x 20in (1/8in) - Bulk 400 Pack

Our review of these corrugated cardboard sheets finds them best suited to small businesses, crafters, and anyone shipping flat, delicate items who needs economical, consistent protection. The single biggest reason to buy is the combination of a large 400-sheet bulk pack and a sturdy fluted core that absorbs shock, making these pads a practical go-to for protecting prints, records, framed art and fragile flat goods during transit or storage.

Key Features

• Bulk quantity: The pack contains 400 corrugated sheets which reduces frequent reordering and suits high-volume shippers or busy craft rooms.
• Standard size: At about 20in x 20in each sheet fits many common square packages, frames, and album covers for fast packing and layering.
• 1/8in thickness: The moderate thickness balances flexibility with cushioning so sheets bend for wrapping yet still absorb impact and protect corners and surfaces.
• Versatile uses: Sheets work as dividers, backing for frames, album protection, craft stock, or packing filler across retail and hobby applications.
• Durable corrugated construction: The fluted layer offers shock absorption and rigidity which helps prevent bending and surface damage during handling and shipping.

Who It's For

These sheets are ideal for online sellers, record stores, photographers, and makers who frequently ship flat items and need a consistent, low-cost protective layer. The large 400 count is particularly attractive for businesses or crafters who pack many orders or want on-hand material for framing and projects.

Shoppers who need custom-cut sizes, thicker board for heavy-duty pallet protection, or small sample quantities should look elsewhere; smaller hobbyists may prefer lower-count packs or pre-cut sizes if 20in x 20in is too large for their regular projects.

Pros & Cons

Pros

• High value per pack with 400 sheets reduces purchasing frequency for frequent shippers.
• Good protection from the fluted layer that cushions and helps prevent impact damage.

Cons

• Some customers find the 20in x 20in size larger than needed for certain items, which can require trimming.
• Thickness and cut quality received mixed feedback, so those needing precision cuts may need to trim or test a sample first.
