  • What is corrugated?
    Everybody's seen it... just think of pizza boxes, or the big boxes that hold new refrigerators and televisions. Corrugated is built like a sandwich - characteristic arches of wavy "fluting" lying between two pieces of smooth board on the outside. Corrugated boxes are easy to recognize. Corrugated is made of paper and has an arched layer, called "fluting," between smooth sheets, called "liner." The corrugated most commonly used to make boxes has one layer of fluting between two smooth sheets. But there are many types of corrugated available, each with different flute sizes and thicknesses. Corrugated is an extremely durable, versatile, economical and lightweight material used for custom-manufactured shipping containers, packaging and point-of-purchase displays, in addition to numerous non-traditional applications ranging from pallets to children's toys to furniture.
  • What is a corrugated container ?
    Corrugated paperboard is the most popular raw material for transport packages of a wide variety of products varying from fresh fruit and vegetables, consumer-packed manufactured products, household appliances and industrial machinery to semi-bulk transports of various commodities in large bins. It is equally suitable for all the different modes of transport, e.g. shipping by sea or by air. This versatility is largely due to the possibility of using different types of raw materials combinations and thereby adapting the quality to each particular requirement and distribution system in a tailor-made way. What is corrugated? Everybody's seen it... just think of pizza boxes, or the big boxes that hold new refrigerators and televisions. Corrugated is built like a sandwich - characteristic arches of wavy "fluting" lying between two pieces of smooth board on the outside. Corrugated fiberboard is a paper-based construction material consisting of a fluted corrugated sheet and one or two flat linerboards. It is widely used in the manufacture of corrugated boxes and shipping containers. The corrugated medium and linerboard are made of paperboard, a paper-like material usually over ten mils (0.010 inch, or 0.25 mm) thick. Paperboard and corrugated fiberboard are sometimes called cardboard by non-specialists, although cardboard might be any heavy paper-pulp based board. Corrugated fiberboard can be specified by the construction (single face, singlewall, doublewall, etc), flute size, burst strength, edge crush strength, flat crush, basis weights of components (pounds per thousand square feet, grams per square meter, etc). The choice of corrugated medium, flute size, combining adhesive, and linerboards can be varied to engineer a corrugated board with specific properties to match a wide variety of potential uses. Double-wall corrugated board is also produced for high stacking strength and puncture resistance.
  • What type of grade and class of board do we supply?
    We supply any grade and class of board including E flute, B flute, C flute and all grades of DWB, whether it’s recycled or virgin board.
  • How is a shipper made?
    The corrugated board is creased or scored to provide controlled bending of the board. Most often, slots are cut to provide flaps on the box. Scoring and slotting can also be accomplished by die-cutting. The "Flexo Folder Gluer" is a machine that in one single pass prints, cuts, folds, and glues flat sheets of board to convert them to boxes for any application, from storing old family pictures to shipping the biggest of plasma TV sets to the global market. The most advanced of FFG's can run at speeds of up to 26,000 boxes per hour (about 433 per minute). The most common box style is the Regular Slotted Container. All flaps are the same length and the major flaps meet in the center of the box. The manufacturer's joint is most often joined with adhesive but may also be taped or stitched. The box is shipped flat (knocked down) to the packager who sets up the box, fills it, and closes it for shipment. Box closure may be by tape, adhesive, staples, strapping, etc. A Full Overlap Box is similar to an RSC except the major flaps fully overlap. A Five Panel Folder is shipped flat without a manufacturer's joint and is often used for long items. The box has five long panels, one of which fully overlaps. The ends also fully overlap. A Full Telescope Box has two fully telescoping sections. The sections may be formed by staples, die-cut locks, adhesive, etc. A Partial Telescope Box has two sections. The top telescopes partially over the bottom. A corrugated tray is often used for display purposes or used with a shrink wrap
  • When was corrugated first made?
    1856 The first known corrugated material was patented for sweatband lining in tall hats of Victorian Englishmen. 1871 Unlined corrugated first appeared as a packaging material for glass and kerosene lamp chimneys. 1874 A liner was added to one side of the corrugated material to prevent the flutes from stretching. 1894 Corrugated was slotted and cut to make the first boxes. Wells Fargo began using corrugated boxes for small freight shipments. 1903 Corrugated was first approved as a valid shipping material and was used to ship cereals. 1909 Rubber printing plates were developed which allowed for greater design creativity. 1914 Tariffs imposed on corrugated shipping containers were ruled discriminatory. 1960 The flexo folder-gluer was invented. Flexographic printing virtually replaced letterpress and oil-based ink.
