A multi-ply paper substrate is provided, which comprises at least two plies bonded to one another by an adhesive; a basis weight of 80-200 gsm; an internal bond of 10-180 milli-ft.-lb/sq. in. as measured by TAPPI method 541; an MD tensile of 20-300 lb/inch width as measured by TAPPI method 494; and a CD tensile of 10-300 lb/inch width as measured by TAPPI method 494. Methods of making and using the paper substrate, products made therefrom, and uses of the paper substrate are also provided.

Substrate for wallboard joint tape and process for making same

An article in the form of recyclable packaging material having a water vapor transportation rate of about 500 g/m/day or less. The packaging material has a paper substrate of recyclable paper fibers and a print-receptive layer which is positioned over the outer surface of the paper substrate and has a Parker Print Smoothness value of about 1.5 or less. The packaging material also has a moisture barrier layer positioned over the print-receptive layer. The moisture barrier layer is formed from one or more energy-cured polymers. Also, methods for preparing these packaging materials, including printed packaging materials.

This invention relates to a paper substrate containing high surface sizing and low internal sizing and having high dimensional stability, as well as methods of making and using the composition.

Paper substrates containing high surface sizing and low internal sizing and having high dimensional stability

This invention relates to paper products and/or substrates suitable for being made into wallboard tape (also may be known as joint tape and/or drywall tape) and having improved reduction or inhibition in the growth of microbes, mold and/or fungus. The paper substrate is characterized by its excellent physical properties including cross direction (CD) tensile, machine (MD) tensile, internal bond, wet tensile, hygroexpansivity, curl, bonding properties, bonding of joint tape to joint compound, etc. The paper product of the invention contains a sizing agent and an antimicrobial compound as well as other optional components including without limitation a binder. The paper product of the invention may be produced by contacting the plurality of cellulose fibers with each of the sizing agent, antimicrobial compound, and optional components at any point in the papermaking process, converting process, and/or post-converting process. Finally, the invention relates to methods of using the paper substrate.

Anti-microbial paper substrates useful in wallboard tape applications

One embodiment of a wrapping film comprises a polymer film having, on at least one surface thereof, at least one sealing area comprising at least one varnished area; and a plurality of individual unvarnished areas; wherein, within the sealing area, the area ratio of the unvarnished areas to the varnished area (PV:V) is &#x2266;1; and wherein, within the sealing area, the largest individual unvarnished area is &#x2266;30 mm. Other embodiments are described.

Film for wrapping, methods of making and using

This invention relates to paper products and/or substrates suitable for being made and/or converted into wallboard tape; which also may be known as joint tape and/or drywall tape, having a pH of at least 7.0 and containing a plurality of cellulose fibers, a wet strength additive, an alkaline sizing agent, and an anionic promoter, as well as methods of making and using the same.

Paper substrates useful in wallboard tape applications

This invention relates to composition containing expandable microspheres and at least one ionic compound and having a zeta potential that is greater than or equal to zero mV at a pH of about 9.0 or less at an ionic strength of from 10M to 0.1M, as well as methods of making and using the composition.
