The definitive industry reference on the paper and paperboard packaging sector. Now in a fully revised and updated second edition, this book discusses all the main types of packaging based on paper and paperboard. It considers the raw materials, the manufacture of paper and...
This test is used to evaluate the bending quality of both coated and uncoated paperboard from 0.4 to 1.0 mm (0.016 to 0.040 in.) in thickness made on fourdrinier or multi-ply cylinder machines.
This method is used to determine the rate of water absorption of an unsized or slack-sized paperboard. It is generally suitable for sheets of paperboard 0.2 mm (0.008 in.) thick or thicker. For testing absorbent paper or materials such as blotting, toweling, tissues, or beer mat...
This method (1-3) is suited for the visual estimation of dirt in paper or paperboard in terms of equivalent black area. For dirt in pulp, see TAPPI T 213 "Dirt in Pulp." This method is a visual inspection method for the evaluation of the Equivalent Black Area (EBA) measurement of dirt in...
This test is applicable to paperboards that are medium-sized, with an immersion number between 4.5 and 6.0, to hard-sized, with an immersion number of 3.5 or less, throughout.
The ring crush test correlates with edgewise compression strength of paperboard (1). This method is intended for paperboard between 0.28 mm (0.011 in.) and 0.51 mm (0.020 in.) thick. It may be used with less reliability for paperboard as thin as 0.18 mm (0.007 in.), and as...
1.1 This test method determines the brightness of white, near-white, and naturally colored pulp, paper, and paperboard. Brightness is a commonly used industry term for the numerical value of the reflectance factor of a sample, with respect to blue light of specific spectral and...

The ring crush test correlates with edgewise compression strength of paperboard (1,2). This method is intended for paperboard between 0.28 mm (0.011 in.) and 0.61 mm (0.024 in.) thick. It may be used with less reliability for paperboard as thin as 0.18 mm (0.007 in.) and as...
1. SCOPE: The material defined by this specification is a low expansion, vinyl coated, flexible, dielectric grade, subfoundation paperboard.
Scope and significance The following procedure applies to pulp, paper, paperboard, and paper products, except those containing significant quantities of materials other than water that are volatile at lower than 107°C (224.6°F) or degrade above 103°C (217.4°F). Moisture is significant for...
This European Standard specifies the characteristics and performance of prefabricated panels made of gypsum plasterboard facings complying with EN 520 and a cellular paperboard core intended to be used as a lightweight partition, lining and encasement for general use in buildings. This...
