A variety of large volume paper based laminates are used in the mineral fiber insulation industry as vapor retarder products. A review of constructions will be presented. In vapor retarder applications, paper is married to a variety of other materials to form a flexible composite necessary to form a vapor retarder in-situ for buildings and mechanical systems. Specific applications and criteria acceptance standards will be discussed as well as the industry trends that warrant greener solutions in product construction.
The use of bio-based and renewable Microfibrillated Cellulose (MFC) offers a wide variety of benefits for the production of many paper grades including specialty papers. Internal addition or direct application of MFC to the sheet surface can greatly enhance paper properties.
In addition to the more traditional internal addition, a special applicator has been developed that can be positioned on the Fourdrinier. A liquid dispersion of MFC is forced out of a narrow slot in the applicator and falls as a full-width curtain onto the wet stock.
Machine trials of MFC technology have shown improvements in tensile strength, SCT, sheet smoothness, porosity, ink absorbency, and other properties.
Balázs Tolnai | General Manager Technology of Kruger Inc.
In 2013 a Strategic Alliance was formed between FPInnovations and Kruger Biomaterials Inc. to commercialize the Cellulose Filament (CF) technology. In March 2014 Kruger Biomaterials Inc. completed the construction of the plant in its Trois-Rivières mill, it was successfully started-up and commissioned and in a 12 month-long period the production rate was ramped up. Operating protocols were developed for the production of high quality CF. Currently the plant produces 6,000T/y of high quality CF.
In the past years several pulp and paper applications were tested, over 50 paper machine trials run and commercial CF containing paper grades developed. Parallel to the development in the pulp and paper field, non-traditional CF applications were also evaluated. This presentation will demonstrate how CF can be used in pulp and paper and non-traditional applications, with special focus on strengthening and light weighting.

The quality of paper is usually controlled by using the appropriate pulp grade and auxiliary materials together with selecting the required process settings like the level of refining. However, there are more and more applications where specific paper properties are required. For such specialty papers the blend of pulp and fibers of natural or man-made origin are needed to achieve the desired properties. In this respect lyocell fibers (Lenzing brand name TENCEL®) show useful properties.
Lyocell fibers are produced in diameters from 9-30 microns and are cut to the desired length. As lyocell fibers consist of 100% pulp these fibers mix very well with pulp and can be processed with existing technologies.
The fibrillar structure of Lyocell offers opportunities for researchers and engineers to design fibres with new features to meet specific technical requirements. One of its well-known and still sometimes undervalued properties is its fibrillation tendency, the ability that fibrillar parts peel off from the fibre surface under mechanical stress in water.
In this presentation application of Lyocell fibers for specialty papers will be presented.

Northern Softwood kraft pulps are known for their high strength and quality. The unique growing conditions and fibre management practices of the Canadian forest industry ensure that these pulps have some of the longest, finest fibres in world. Extensible papers made with these pulps are denser, smoother and up to 15% stronger than similar grades made with coarser fibres. Superior strength attributes of papers made from these pulps can be used to reduce fibre costs by using lower grammage papers or by reducing plies in packaging products.
Papers made from long, fine fibred Kraft pulps are superior in quality over papers made from coarser Kraft pulps
This superior quality is used to reduce costs by using lower grammage papers and reducing ply number in packing products

Active microwave packaging is a class of microwaveable food containers, including bags and boxes that use microwave-interactive materials (susceptors) to enhance heating/cooking performance. Susceptor packaging is a growing segment (CAGR: 4.3%) with the US market size expected to reach $285 million by 2020. Commercial susceptors made of metallized plastic films are currently being used, but the market is also looking for low-cost and safe alternatives, that would eliminate the use of plastics and metals. To address this, FPInnovations has developed a technology (patent pending) that consists in printing carbon-based ink onto cellulose-based substrates to produce susceptors that can match the heating performance of existing suceptors, but with lower cost and improved sustainability. This technology has been successfully tested in the laboratory and was also demonstrated on a commercial printing press.
Through a case study (popcorn bag), the presentation will describe the approach used and the technical problems solved. The advantages and challenges of the technology will be discussed as well as outlining the proposed path forward for bringing this technology to market.

Replacement of wax in corrugated structures has been the traditional end use for the majority of aqueous barrier coatings. Application of these materials has centered on converters; who could cost effectively make the short runs required for the wide variety of different applications.
The market for barrier packaging is changing to one with a range of end uses going far beyond corrugated. To meet these needs, there is a continuing call for alternatives not only to wax, but also to extruded poly and fluorocarbons. There is keen interest by both printers and paper mills in products that fit their existing equipment. Yet, to date, introduction of water based solutions has been limited by a complex set of requirements around market dynamics, barrier, and runnability.
In this presentation, we will discuss the changing market, the requirements of barrier coatings that fit the new model, and some solutions.

Water based barrier coatings (WBBC) have been studied intensively during the past years in order to replace the traditional barrier materials. One of the largest challenges for these WBBC’s has been a high risk for pinholes originating from the base substrate leading into discontinuity in the dispersion layer and poorer barrier properties. By increasing the coat weight, the amount of pinholes can be reduced but this may lead into economical and quality issues, thus optimization is needed.
In this study, the role of base substrate variables in dispersion coverage and in the received barrier properties was investigated by studying commercial base paper substrates. Also the effect of how the dispersion film coverage and surface structure influences convertibility of dispersion coated packaging materials was examined. The base paper surface structure was also modified by pre-coating, both with blade and rod coating, and the effect on barrier coverage and properties was studied.
The results showed that base substrate plays a key role when WBBC’s are used. If the structure of the base paper is very open or very rough, gaining good barrier properties is difficult and the amount of pinholes increases which affects most significantly grease resistance. With very porous and rough base material best possible barrier properties at certain total coat weight were reached by double coating and by using pigments with high aspect ratio. The base paper structure had also large impact on the convertibility properties, for example creasability, of barrier coated paper.
Mike Browne | Brand Manager of Sappi North America
Produced by processing woodfibre down to the smallest fibre component, nanocellulose was developed during the 1980s, but was not successfully commercialised because of the energy intensive production process involved. Sappi's patented process does not require significant energy inputs and allows nanocellulose to be dried and re-dispersed without compromising fibril width. There is on-going investigation into a broad range of applications including significant opportunities for packaging and specialty grades.

Printed electronics (PE) are being developed as an alternative to traditional electronics due to the more efficient use of materials and lower cost of production. The overall goal of this study was to understand how metallic pigments in conductive inks in PE are partitioned during landfill disposal and paper recycling conditions. The purpose is to assess the potential environmental impacts of PE landfilling in terms of metal leaching and to help provide new strategies for sequestering metallic ink components while paper-based PE are subjected to conventional paper recycling methods. The objective of this research is to study the fate of PE metallic pigments by conducting research that will analyze the characteristics of the partitioning of the metals in the recycled papermaking system, the potential leaching characteristics of the inks, and the ink film characteristics on paper that will help to speculate about whether or not the metallic pigments can removed from the paper fibers. Three studies were conducted to address each of these specific objectives In the first study, three conductive inks used to create PE - nickel, silver flake and nanoparticle inks were printed on label paper substrates simulating PE materials, which were then pulped and screened in bench-scale experiments. Accepts, rejects, and wastewater streams were collected and analyzed using Atomic Absorption Spectrometry (AAS) to measure the metal concentrations in each stream and create a material balance around the pulping and screening process. Results showed that the nickel and silver flake inks appeared to travel in a larger proportion with the “accepts” stream, while the silver nanoparticle mostly partitioned to the wastewater stream. The second study conducted a landfill simulation experiments to evaluate the potential leaching of metal pigments from polymer and paper based PE while subjected to landfilling conditions using EPA methods 1311 and SW 846. Results show that nickel ink used could potentially form hazardous leachate if landfilled in large quantities, because it crossed 5 parts per million in the leachate. The two silver inks did not cross 5 parts per million threshold named in the TCLP test and do not pose a leaching potential in a landfill. The third study involved a qualitative assessment of nickel and silver conductive ink penetration and adsorption/absorption characteristics in paper substrates using scanning electron microscopy (SEM). From these microscopic observations, we can speculate about the potential ease or difficulty of removal and recovery of these pigments from the paper fibers during recycling. Results showed that nickel and silver flake inks do not penetrate the fiber pores and are mostly concentrated in the paper substrate surface, but the silver nanoparticle pigments have penetrated further into the sheet and also into the pores of the fibers themselves. Based on these observations, it is likely that nickel and silver flake inks can be removed and recovered more easily than the silver nanoparticle ink. This research shows PE could provide papermakers with an opportunity to innovate their process and potentially create a revenue stream by recovering metallic pigments.
