Corrugated, Solid Fiber, and Chipboard

Paperboard is a paper-like material, usually over ten "mills" (0.010 inch) in thickness. Some types of paperboard (corrugating medium and linerboard) are used in the construction of corrugated fiberboard. Other types of paperboard are used in the manufacture of cartons, set-up boxes, partitions and other products.


Today paperboard packaging in general, and especially products from sustainable sources, are receiving new attention, as manufacturers dealing with environmental, health, and regulatory issues look to renewable resources to meet increasing demand. It is now mandatory in many countries for paper-based packaging to be manufactured wholly or partially of post-consumer waste.

Within the classification of paperboard are other grades and descriptions – some of these are used specific to certain industries or applications – just a few examples of paperboards Alta Max inventories and works with are:

1. Solid Fiber – all classes and grades per ASTM-D4727, PPP-F-320 including weather resistant, fire retardant, V2S, W5S, etc.. as well as other military and commercial grades.
2. MIL-PRF-50449 – Ammunition container filler board.

4. Onion Skin – MIL-P-157 and other military and commercial grades
5. Cheesecloth – CCC-C-440 and other military and commercial grades
