Corrugated cardboard is a reusable material made from a renewable resource. It is environment friendly, being recyclable and ultimately biodegradable. Over 70% of the cardboard produced each year in the uk is made from recycled fibers. Corrugated board is not made from paper[paper?:paper sample maker cutting machine] derived from tropical forest hardwoods as they are unsuitable for the process. Instead the paper industry uses fast growing softwoods that are being replanted faster than they are being used.
Single wall corrugated cardboard is made from three distinct parts a flat paper “outer liner”, a corrugated paper[corrugated paper?:DCP-H series sample cutter plotter] “fluting” and a flat paper "inner liner".
Double wall corrugated cardboard is made from five distinct parts. The same components as single wall board are used but double wall has an additional "inner liner" and an additional "fluting" for extra strength applications.
Rolls of the required paper are fed into a "corrugator" machine and during the cardboard manufacturing process the paper components are bonded together with a water based glue which results in a strong sandwich type construction which gives corrugated cardboard its excellent cushioning characteristics, rigidity and structural strength.
Corrugated board used for packaging[packaging?:DCP-H series packaging sample cutter plotter] comes in a large number of "board grades" which specifies the type, weight and thickness of the "liners" and "fluting" used. Some grades can also have special coatings applied during the manufacturing process which facilitates improved printing[printing?:printing cutting finishing solution] quality on boxes requiring graphics[graphics?:graphics pattern] images etc.
Boxes are manufactured in a wide range of board grades which includes the coarse ‘C’ flute, fine ‘B’ and extra fine ‘E’ flutes. The ‘B’ flute is the most widely used for most packaging boxes. It is very robust ( difficult to crush) and has good compression strength and printing characteristics. The ‘C’ flute (slightly wider than 'B') offers a greater compression strength but provides less crush resistance. Double wall boxes are usually manufactured in "BC" flute or "EB" flute which (as their names suggest) are boards made by combining two flutes into a double wall sandwich.
If a standard style box design is not suitable for a particular application a new design may have to be created. These designs are known as "die-cuts" and are produced on different machinery which stamps out the box and which needs a specially made cutter for every job. This cutter is known as a "die-cut pattern cutter[pattern cutter?:pattern cutter]", Cutcnc[Cutcnc?:cutting machine sample maker manufacturer] offer die-cut oattern cutter can be uesd to cut all the design with high speed and percision.
Although it is possible to make cardboard boxes from stock sheets of cardboard this is usually very wastefull in both materials and in the box manufacturing process and consequently cardboard usually has to be manufactured specifically for every job. It is for this reason that all cardboard box manufacturers have to specify a minimum order quantity that is calculated from the square metres of cardboard required to take a particular box and on the board grade selected.
The other limitations on manufacturing a specific cardboard box is whether the sample of box, its size and any printing requirements is within the manufacturing limitations of die-cut pattern cutter cardboard box sample cutting machine[cutting machine?:CUTCNC sample maker cutting machine] can be be used to cutting cardboard patterns, solve the problem of material waste and save the die cut cost and labor. Can solve the problem of manufacturing limitations.
