Cardboard bins are a type of corrugated box that is usually long, thin
and rectangular-shaped with no top or lid. They are ideal for storage,
organization and display of many different objects and products. They
are inexpensive and generally are made of recyclable materials.
The major difference between bins and regular cardboard boxes is their angular design. While most cardboard boxes have rectangular cross sections, bins tend to be trapezoidal. Their configuration is specifically made for easy access to whatever the bin is holding. They can be found in homes and places of business, where they are used for storage, warehouse applications and for keeping records. They are used widely in retail contexts to keep track of inventory, records, small parts, files, folders and small objects for sale. Unlike standard corrugated boxes, cardboard bins are not designed for packaging, shipping or mailing applications because they are not coated with a waterproof finish, nor do they come with lids or foldable flaps to keep their contents secure. However, many are able to hold up to 200 pounds safely. For extra organization, many come with cardboard dividers. The exterior is usually white and can be written on with markers or pens, and they are often labeled with stickers. They are specifically designed for storage on a shelf, rack or closet area.
Cardboard bins used for storage and organization are usually sold in packs of 20 to 50, but they are sometimes offered to very large operations in larger quantities. Like all cardboard container varieties, these bins are fabricated from recycled paper, sawdust and wood chips that have been put through a chipper to produce fine, uniform granules. The raw material is then pressed together with pressure and heat to form thin sheets of brown paper. To form the cardboard itself, multiple sheets are then bound together. The interior sheet is usually corrugated, meaning it has an alternately curved groove pattern, while the exterior is more than likely made of white cardboard, which has been bleached. They are then cut to size and attached to one another to form a bin. Cardboard bins are always shipped flat and assembled by the company that buys and uses them, which saves on shipping cost as well as space.
