The pulp and paper industry and its suppliers have come to realize that acting in a sustainable manner is in the best interests of all stakeholders. Because of this, suppliers have been working on new technologies to help the industry reduce its carbon footprint. The use of hyperplaty clays and multi-pigments by the industry is also discussed.

Makers of coated paper are using increasing quantities of minerals, including calcium carbonate, according to Harry Bigelow, VP of Technology for Omya Inc. Bigelow reports that paper with multiple coatings is produced more often in Europe than in the US. Predictions for the industry include increased production of aseptic packaging for food products., The use of minerals in paper machine wet ends has been steadily increasing during the past 50 years, especially in Europe. In the past quarter century, North American mills have [...]

The improvement of starch-based binders has made the use of size-press pigmentation more effective. Size-press coating applications have not worked well in the past, but there are many examples of improved hardware and starch copolymer binders being used in today's size presses. Binder systems for size-press coating must be selected with the same care as those for blade coating. The use of starch copolymer products (SCP) provides stability benefits because there is no surface charge, and SCPs are resistant to damage from temperature extremes., Size-press pigmentation technology is not new. It has been available to papermakers for the past 40 years. Early attempts to exploit the size press as a coater were made on [...]

Blade coating involves the application of pigments to uncoated sheets to upgrade the performance of the paper by smoothing the inherent surface volume roughness. The benefits of coating are seen in the areas of paper gloss, print gloss, smoothness, brightness, shade and opacity. Structured pigments, in particular, have extensive applications in opacity improvement as well as in the enhancement of fiber coverage and smoothness. The proper selection of coating relies on grade structure, basis weight and end use application., Use of structured pigments in coating formulation increases light scattering in paper grades and higher bulk in board grades Pigments applied to an uncoated sheet via blade coating enhance the [...]

Projections on supply, demand and pricing in the paper market next year In last year's survey of paper trends, we forecasted that while 'we haven't seen any signs of economic [...]

The very same products used to brighten papers are discolouring them at an alarming rate, argues David Bland. Over the past couple of years we have all noticed that, in [...]

Yellowing of paper can be minimised by raising fount quality and controlling acidity levels, says Ron Brindley. In response to David Bland's Opinion I'd firstly like to say that coated [...]

Supply balance, strong demand, innovative distribution, product stratification--and heavy dot--com promotional spending--boost paper marketing efforts and profit levels. Now that the new century has begun, a retrospective look at recent [...]

Scientists at Stanford University recently developed a method to store energy in ordinary paper by coating it with ink infused with carbon nanotubes and silver nanowiers. These nanomaterials are great [...]

The past year hasn't brought any extraordinary changes in catalog paper usage over 1991. This isn't surprising, as we haven't seen any strong signs of economic recovery this year. Nevertheless, [...]

Printed paper is a key ingredient in many packages and labels. And whether the printing provides information, graphics, or both, it has to be protected. One way to do this [...]

Coated free-sheet paper sales rose during most of 1995, although sales slowed as inventories and prices rose during the 3rd qtr. Publishers used less paper and discounting became more frequent. Demand for coated paper will be more moderate during 1996 and prices are expected to drop during 1997. Coated free-sheet papers are found in magazines, brochures and catalogs., FORECAST (000 tons) 1996e 1995e 1994 Production (2) 4,647 4,492 4,358 % change 4 3 11 Capacity (3) 5,016 4,826 4,647 % change 4 3 3 Utilization rate (%) 92.6 [...]

More publishers switch to freesheet NEW YORK CITY--More publishers are continuing to upgrade their magazines with coated freesheet, according to this year's paper use survey conducted by the Magazine Publishers [...]
