Why Corrugated?

Corrugated. It's not just a brown box. Corrugated is a complete, high-performance material design, manufacturing and delivery system. Corrugated is the preferred packaging material because it is:

  • Durable
  • Versatile
  • Lightweight
  • Sustainable
  • Environmentally Responsible
  • Made from a Renewable Resource
  • Customizable
  • Protective
  • Graphically Appealing
  • Cost-Effective

What is Corrugated?

  • A High-Tech Engineered Material. The vast majority of corrugated products are designed and proto typed with advanced, computer-aided design and manufacturing systems, providing customers with the best and most cost-effective solutions to their packaging challenges.
  • Infinitely Customizable. Corrugated offers thousands of possible combinations of board types, flute sizes (caliper), basis weight, adhesives, treatment and coatings, including flame retardant and static control protection.
  • Tenaciously Protective. Corrugated combines structural rigidity with superior cushioning qualities. Containers, packages and pallets nest products in an optimally protective environment, so even heavy or fragile content arrive undamaged.
  • Graphically Appealing.Corrugated containers and packaging are mobile billboards that create product image wherever they travel. Corrugated displays are eye-catching modular units that can be set up quickly and recycled at the end of a promotion.
  • Preeminently Cost-Effective. One of the least expensive containers ever developed, the overall cost of corrugated shipping containers is usually between one percent and four percent of the value of the goods they carry.
  • Environmentally Responsible.  Corrugated, made from a natural renewable resource, has a great environmental record. Corrugated is frequently manufactured using high percentages of secondary fiber (including old corrugated containers, kraft, old newspapers and even straw), thereby diverting these materials from the municipal solid waste stream.

About Corrugated

Corrugated fiberboard, or combined board, has two main components: the linerboard and the medium. Both are made of a special kind of heavy paper called containerboard. Linerboard is the flat facing that adheres to the medium. The medium is the wavy, fluted paper in between the liners..

There are four types of combined board:

  • Single Face: One medium is glued to one flat sheet of linerboard.
  • Single Wall: The medium is between two sheets of linerboard. Also known as Double Face.
  • Double Wall: Threesheets of linerboard with two mediums in between.
  • Triple Wall: Four sheets of linerboard with three mediums in between.

Box Dimensions

Dimensions are given in the sequence of length, width and depth. Internationally, the words length, breadth and height may be used to express these dimensions. The dimensions of a box are described based on the opening of an assembled box, which can be located on the top or the side, depending on how it is to be filled. The opening of a box is a rectangle; that is, it has two sets of parallel sides. The longer of the two sides is considered its length, the shorter of the two sides is considered its width. The side perpendicular to length and width is considered the depth of the box.

Dimensions can be specified for either the inside or the outside of the box. Accurate inside dimensions must be determined to ensure the proper fit for the product being shipped or stored. At the same time, palletizing and distributing the boxes depends on the outside dimensions. The box manufacturer should be informed as to which dimension is most important to the customer.
