Growing demand for sustainable products has led to increased interest in the use of paperboard as a structural material. Paperboard products are almost exclusively manufactured by embossing, pulp molding, and bending processes. Other well-known forming methods, such as deep or stretch drawing, are only rarely applied to paperboard. This is primarily ascribed to the lack of knowledge concerning ...

BACKGROUND AND OBJECTIVES Paper and paperboard packaging play an important role in safety and quality of food products. Common bacteria of paper and paperboard food packaging could grow due to specific conditions included humidity, temperature and major nutrition to contaminate the food. The purpose of this research was to investigate numbers and the types of bacteria in the food packaging pape...

The paper industry's experiences with PCBs were chronologically reviewed at a recent "PCB Workshop" sponsored by the Grocery Manufacturers of America, Inc. (1). This history goes back somewhat over a year, at which time two paperboard manufacturers were apprised of the presence of PCBs in folding cartons for packaging dried fruit. These two manufacturers immediately began searching for the sour...

The in-plane orthotropic elastic constants of machine-made paper and paperboard were determined in a compact testing machine equipped with an optical extensometer and using a high-speed digital image sensor. Commercial copy paper, sack paper and paperboard were tested in a standard atmosphere of 23

Paperboard is widely used in different applications, such as packaging and graphic printing, among others. Consumption of recycled paper is growing, which has led the paper-mill packaging industry to apply strict quality controls. This means that it is very important to develop methods to test the quality of recycled products. In this article, we focus on determining the recovered-fiber content...

Goods that are shipped world-wide travel protected by packages that are frequently made of corrugated board. Therefore, the strength of corrugated board containers is crucial for preserving the content, while an optimization of corrugated board containers is essential to save money and resources. Unfortunately, standard compression tests show a wide dispersion in container performance, and so, ...

sizing of paperboard has a distinctive position in packaging grade paperboard material. optimization of sizing by alum-rosin at neutral ph in 4 layered paperboard (330 g/m2) wereevaluated in this study to find the optimum ratio of alum- rosin loading in the process. fixed amount of 1% cationic dispersed rosin together with alum as a fixing agent at 5 different levels of 1, 1.5, 2, 3, and 4% (ba...

Mineral oil contamination in foods, deriving from a variety of sources, has been studied for quite a long time[2-4]. One of the major sources of contamination is paperboard packaging, an issue known since 1997[2], even though it has gained great attention only recently[5,6] Such a contamination derives from the printing inks applied directly to the packaging, and/or from the ink used in the new...

Compressibility of liquid flame spray-deposited porous TiO2 nanoparticle coating was studied on paperboard samples using a traditional calendering technique in which the paperboard is compressed between a metal and polymer roll. Surface superhydrophobicity is lost due to a smoothening effect when the number of successive calendering cycles is increased. Field emission scanning electron microsco...
