TAPPI Introduction to Printing Course

The TAPPI Introduction to Printing Course delivers a comprehensive, introductory overview of traditional offset and emerging digital technologies, equipment review, color perspective, troubleshooting and more. An optional tour of a printing plant is offered to reinforce the curriculum learned. This training event is co-located with PaperCon 2020 in Atlanta.

TissueCon 2019

More than 200 people were onsite at Fox Cities Exhibition Center in Appleton, WI to attend Tissue 2018. Tissue professionals across the entire supply chain networked, learned, and shared ideas over the four day conference.

Bringing the safety message home: PPSA annual meeting meets the challenge of change

Moving to Mobile for its 73rd annual event, the Pulp & Paper Safety Association (PPSA) conference program touched all the bases, practical and theoretical, and then some. Nancy Garry, HRP Associates, also led a full day session dealing with the fundamentals of OSHA compliance in the paper industry.

Rice straw-based sustainable food packaging material with improved strength and barrier properties: Development and characterization, TAPPI Journal October 2023

ABSTRACT: Sustainable food packaging paper with high barrier and strength properties was developed with rice straw nanocellulose materials. Pulping and bleaching of rice straw were performed using an organosolv pulping and DED (D: chlorine dioxide bleaching; E: sodium hydroxide extraction) bleaching sequence. Bleached rice straw pulp was refined to 90°SR using a laboratory Valley beater. The laboratory handsheets were prepared using pulp slurry at 40°SR and 90°SR. The handsheets of cellulose nanofibrils (CNFs) made of highly refined pulp (90°SR) were surface sized using alkyl ketene dimer (AKD) wax to increase the barrier properties of paper for selective food packaging applications. The paper samples were tested for mechanical, optical, surface, and barrier properties, including tensile index, burst index, tearing index, bending stiffness, elongation, porosity, apparent density, opacity, Cobb value, water vapor transmission rate (WVTR), oil and grease resistance, and contact angle. The refined pulp (90°SR) was analyzed using field-emission scanning electron microscopy (FE-SEM), and it was observed that the morphology of the developed fibers changes to the nanoscale (<100 nm) for at least one dimension. The particle size distribution of the refined pulp using DLS analyzer also confirmed the cellulose fibers to near nanoscale. It was concluded that nanofibers were formed by a high degree of the mechanical pulp refining process and found to be much more economical than alternative processes in this direction. The sample handsheets of CNFs showed good strength and barrier properties. The barrier properties further increased when surface sizing was done using low-cost, nontoxic, and biodegradable AKD wax.
