The pulp slurry is then used to make new paper and fiber products. The sheet can then be converted with the same processes used for other corrugated manufacturing into any desired form.
Part of the scoring and cutting takes place in-line on the corrugator. Specialized equipment is necessary for the material construction of SFL, so users may expect to pay a premium for these Corrugated paper. Such plants are known as "integrated plants". The high rates of post-consumer recycling reflect the efficiency of recycling mills to clean and process the incoming materials.
Box closure Corrugated paper be by tape, adhesive, staples, strapping, etc. The baled boxes are put in a hydropulper, which is a large vat of warm water for cleaning and processing.
Alternatively, sheets of corrugated board may be sent to a different manufacturing facility for box fabrication; these are sometimes called "sheet plants".
Film-backed pressure-sensitive tape stays intact: The box is shipped flat knocked down to the packager who sets up the box, fills it, and closes it for shipment. All flaps are the same length from the score to the edge. The corrugated board is creased or scored to provide controlled bending of the board.
The certificate is not required, but it if is used that implies compliance with regulations relating to the certificate. Mill and corrugator scrap, or broke, is the cleanest source for recycling.
They can be compressed and baled for cost effective transport. However, this cost is often offset by the savings over a separate paperboard sleeve and the labor necessary to assemble the completed package.
The size of a box can be measured for either internal for product fit or external for handling machinery or palletizing dimensions.
Many extraneous materials are readily removed.
Typically, the longer major flaps meet in the middle and the minor flaps do not. Boxes are usually specified and ordered by the internal dimensions. Stickies can originate from book bindings, hot melt adhesivespressure-sensitive adhesives from paper labelslaminating adhesives of reinforced gummed tapes, etc.
Most often, slots are cut to provide flaps on the box. Scoring and slotting can also be accomplished by die-cutting.
Single-face laminate[ edit ] A limitation of common corrugated material has been the difficulty in applying fine graphic print for informative and marketing purposes. Several technologies are available to sort, screen, filter, and chemically treat the recycled paper. Due to these characteristics of corrugated, it has been mainly printed using a flexographic process, which is by nature a coarse application with loose registration properties.
Recycling[ edit ] Old corrugated containers are an excellent source of fiber for recycling. The reasons for this stem from the fact that prefabricated corrugated sheets are relatively thick and spongy, compared to the thin and incompressible nature of solid fibre paper such as paperboard.
A more recent development popular in usage is a hybrid product featuring the structural benefits of corrugated combined with the high-graphics print of lithography previously restricted to paperboard folding cartons.Welcome to Riverside Paper Co.

Corrugated fiberboard is a material consisting of a fluted corrugated sheet and one or two flat linerboards. It is made on "flute lamination machines" or "corrugators" and is used in the manufacture of shipping containers and corrugated boxes.
The corrugated medium and linerboard board both are made of kraft containerboard, a paperboard .Download
