General Information on Paper Coating

The main reason of coating is to improve the surface quality of paper or board. The excellence improvement can be aimed at optical properties such as brightness, gloss or opacity, at tactile property such as smoothness, but, most importantly, at print-ability and print image value. The application of (usually white) pigments to the base paper surface enhances the brightness of the paper. In addition, the opacity increases due to the high light scattering of the pigments. This improves the optical appearance, because the shine through of the back side printing is reduced. Also, the coat layer evens out the surface landscape of the sheet, resulting in an improved smoothness, which in turn gives a better gloss.

The coat layer reduces the diffusion of ink into the paper sheet. Therefore, the ink does not spread as much and the print image is clear and sharp. The print density and the print gloss are enhanced, and the ink insists is reduced compared to uncoated papers.For specialty papers, the coat layer can have functional properties. Examples are the thermo sensitive layer of thermal papers or the capsule containing coat layer of carbonless papers.

The benefits of applying a coating layer become very apparent when comparing paper surfaces with different coatings. The SEM (scanning electron microscope) micrograph of an 80 gsm wood free base paper shows multiple layers of intersecting fibers. The paper surface is characterized by hills and dales formed by the fiber mesh. The voids between the fibers impair the smoothness and uniformity of the paper surface. The next micrograph shows a percolated paper at the same magnification for comparison.

A pre-coating of just 10 gsm per side suffices to cover up the majority of voids and fiber crossings. This helps to smooth and even out the paper surface. Paper surface quality can be further enhanced by the application of a top coat. Coating the paper with another 12 g m–2 per side distinctly enhances the existing pre-coated surface quality, with a number of dominants fiber structures and valleys still remaining visible. Subsequent calendaring achieves an additional quality gain by enhancing smoothness and gloss. The resulting surface is flat, with a minimum of irregularities.

The lighter and more densely packed structure on the outside of the paper sheet is the pigments of the coat layers.

 

The caliper of the coat layer varies according to the changing thickness of the base sheet. The surface is smooth so, by coating, paper and board can be upgraded to a higher quality level with added value.

Know About Paper Manufacturers & Paper Suppliers

Paper manufacturers and paper suppliers are the administrators behind present quality paper that is made available to buyers. They arrange the processes and makes sure that the paper gets made, is brought into a usable state and gets deployed and distributed among all those who would require it. Paper manufacturers and paper suppliers have a large say in the way paper is manufactured and deployed all over. Without them, the entire process cannot be completed and will be a big work out in futility.

Paper manufacturers as the words suggest, takes charge of the manufacturing procedure. They oversee all the manufacturing operational work that is concerned. They are involved from the start when the trees are rooted out to warehouse and atthe end where the pulp is made into papers in sheets or in rolls. There are many steps involved from the start to the end and the manufacturers have to make sure that every process is running smoothly to produce the right kind of papers in the end.

After the manufacturing process, the supplier comes into play. The suppliers’ feedbacks monthly will be the deciding factor for the manufacturers to decide how much they will produce the next month. The suppliers will then ship in the papers after it has been produced. The papers comes in varied forms to suit different users – printers, packaging companies, retail shops, offices, schools, and government sectors.

For the larger sized papers required by printers and packaging companies, the papers will either come in large sheets or in rolls. The papers that comes in rolls are usually required by customers who needs the paper in a customized size. The paper in rolls will then be converted by a paper convertor to the customized size. This process is also known as converting/sheeting.

Without the paper manufacturers and suppliers, the end users will have difficulties purchasing papers. With the increase need of more knowledge by the general public and with more children pursuing their studies, paper demand will never cease.

JPP Far East (S) Pte Ltd is one of the paper suppliers in Singapore with an in-house converting machine to provide customers with an all-rounded service.

How to Use White Papers to Market Your Business

You have most likely heard about white papers if you work in a technology-intensive industry. But these advertising powerhouses shouldn’t be ignored in other industries as well. No matter what you’re advertising or promotion, if you need to sell or promote it to high level executives or it’s a very high ticket item, white papers can be a highly effective marketing tool.
Let’s take a look at some of the fundamentals about white papers for those who arenot as familiar with them and how they might help your business.

What are White Papers?

A white paper is a type of report frequently used to market a product or service to executive-level buyers. Since these kinds of buyers might need to make a case for the purchase to a board or a supervisor who has the concluding say, a report makes the most sense. It lays out all of the information people would need to make an educated purchasing decision without spending the whole report on a hard trade approach.

Why White Papers Work

White papers are helpful since they focus on education and problem solving. The basic idea is this: you identify a problem your target market has, you present them with a general solution or strategy and educate readers about that resolution, and then you close the white paper with a more precise pitch for your own company’s product or service as the solution to their needs.

How to Use White Papers Effectively

After you figure out how to write a white paper, you have to get that white paper into the hands of prediction. Here are 3 common ways you can do that to start the sales rolling in:

1. Share out your white papers through your website. While you can use them to build an email list, remember that the main idea is to get your white paper into as many targeted hands as possible — not making people jump through hoops to get it.
2. Share out them through white paper directories online.
3. Current hard copy versions of your white paper to prospects at meetings, conferences, or other in-person events.

While white papers are best known as technology marketing tools, you can use them to market just about everything. For example, you could use a white paper to sell your Internet marketing consulting services or just about any product targeting B2B customers. So go ahead. Search your competitors’ sites to look for examples of industry-specific white papers in action, and then give white paper writing a try.

What is A4 Paper?

A4 paper is the standard paper size used worldwide, with the exception of countries. A4 paper is about 8.27 inches by 11.69 inches (21 cm by 29.7 cm). This and other types of “A” paper sizes are based on a metric measurement system and established through international European standards.

Basis for Different Sizes

A4 paper and a-like sizes are based on metric dimensions. An A0 piece of paper, when spread flat, has apart of one square meter and is the largest dimension at 84.1 cm by 118.9 cm. A0 paper, cut in half, becomes size A1 at concerning 59.4 cm by 84.1 cm. A1 cut in half is A2, and so on throughout A6.
This produces paper with dissimilar sizes, but all with a 1:1.414 height-to-width part. European standards also wrap B paper sizes. B0 paper is a meter wide and 1.414 meters tall; B1 is B0 cut in semi, and so forth through B5.
The worth of this system for paper sizes is that every size is proportionately identical to the next. A4 paper, for example, is 21 cm by 29.7 cm, while A3 is 29.7 cm by 42 cm. If someone has text or images on a sheet of A4 paper and wants to increase it onto A3 paper, it can be done fairly easily without lose any of the content of the document. This amount, which uses the square root of two, or 1.414, is recognized as the Lichtenberg Ratio, named for the German physicist who initial noted its usefulness.

Size and Standardization

Paper sizes were consistent in Germany in 1922, and adopted during Europe in 1930, via Standard 216 of the International Standards Organization. The ISO is a non-governmental unit that publishes international values. While the standards have been efficient occasionally, the sizes used have been maintained since the early on 20th Century.

Paper Weight

The mass of European paper is based on the metric scheme and is standardized under ISO Standard 536, initially developed in 1976 and updated in 1995.

What is Waterproof Paper?

Waterproof paper, like the word itself, is waterproof. It is designed to repel and stay undamaged by water.When used in combination with waterproof ink, waterproof paper should in fact be able to survive direct exposure to water without the paper or its contents being altered in any way. Various papers are made exclusively to be waterproof; paper that is not designed to be waterproof can be put through lamination to make it waterproof or at most water resistant. This type of paper is usually used for purposes such as packaging; Waterproof paper is suitable for maps and guidebooks, as many persons use these items outdoors when situation can often be wet and unforeseeable.

There are different ways to make paper waterproof, some by technology, some by coatings and others from synthetic materials (YUPO Synthetic Paper). Some waterproof papers are complete with thick, tightly-bound fibers that avert water from saturating the paper. Such fibers prevent the paper from deteriorating, dissolving, or changing form. Sometimes, coatings of a variety of forms are used to make paper waterproof. Paper can be coated with synthetic materials, such as plastics, which repel water and avert the paper from being spoiled.

Waterproof packaging paper is important, as packages often enclose objects which are susceptible to water harm. Most packages that need to be shipped from one position to another are ready out of thick, layered materials, such as cardboard, which can keep away or absorb a great amount of water but still remain useful. A few packages are wrapped and shipped with glossy materials, alike to the coatings placed on some paper that keep away water. It is also vital that labels worn for packaging are printed on waterproof paper. If they were not printed on waterproof paper, they could be cracked or otherwise rendered unreadable if bare to water.

Waterproof paper is also usually used by folks who need to use paper outdoors. Backpackers and hikers use maps to discover where they are going; the maps need to live some amount of moisture. People in the military also value the durability of waterproof paper, as it can be used in many dissimilar environments. Maps and vital communications can be sent on paper without risk of behind damage because of rain or other sources of moisture. Public who work on boats or near bodies of water also use waterproof paper to decrease the risk of harm from splashing or submersion.

Creating Sustainability in the Pulp and Paper Industry

For all goods as well as resources alike, improper usage leads to undesirable results. With paper, the scenario is similar.

Paper, being a major resource in industries, offices and schools all over the world, finds many users in all its forms – pulping, bleaching and recycling paper. Sustainability has now become one of the top concerns of many countries.

How precisely can resources be mismanaged in an industry as mechanical as this?

For starters, the pulp and paper industry is the fifth largest user of electrical energy. It is also the maximum consumer of water to give the least ton of yield.

Where are we going with this?

It comes as no surprise that the demand for paper has quadrupled exponentially in the past few decades. In order to make these split ends meet, there is extreme plundering of wood to satisfy this rising order.

Logging of old expansion forests accounts for less than 10% of wood pulp. The understandable here to create a protected, sustainable way for paper manufacture seems to spending in recycling. However, improper practices in the recycling business causes more harm than good because of

1. By-products and waste being generated
2. This waste being irresponsibly dumped in water bodies/ open lands causing air and water pollution

Clean technology and sustainable use are the much needed solutions to this vital problem.

Many companies ensure proper production, with least surplus, no-dumping grounds for waste materials and pure, neat final products. Using right technology, though, requires allotment of resources specifically for this purpose by the government and industries so that well-organized equipment that is in good condition is used.

Sustainable use, too, depends on sensible and appropriate usage of the product without causing harm to other resources or litter. On a larger scale, watchfulness on the part of control bodies in the manufacturing could create more products for usage and storage space. By create, we mean sensible use without waste or plunder those results in a cleaner atmosphere that is possible for more tree growth, and in the end an environment that gives more yields.

Paper products are vital to civilization, as they have enabled literacy and educational development. Helpful production and use will ensure not only a happier society, but also a Green Earth.

What is the Paper Manufacturing Process?

The procedure of making paper dates back to ancient Egypt. This manufacturing procedure uses natural fibers and materials, liquid, and pressure to make paper. While the equipment and materials worn in the paper manufacturing procedure have varied over time, the real process remains essentially unchanged.

In the paper manufacturing procedure, organic materials such as wood or bamboo are estranged into fibers or ground into a very well powder. The reason of this step is to create uniform fibers that are then awash in an acid or base solution to make cellulose in a process called pulping.

 This cellulose material is the major component of paper. In field papers, such as parchment, cloth fibers may also be used in rest of cellulose as part of the paper manufacturing procedure.

There are three methods used in the pulping method: chemical, mechanical, and de-inking. The first two processes are used to create virgin paper, while de-inking is used to make recycled paper products. Every of these pulping methods has it’s possess advantages and disadvantages in the paper manufacturing procedure.

After the natural fibers are pulped and twisted into cellulose materials, filler materials may be added to make special characteristics in the end product. This method is called sizing, and it can be used to make paper with a higher ink absorption rate or to alter the color of the over paper. These filler materials may comprise china clay, bleach, chalk, or additional additives.

The treated cellulose pulp is run through a drying procedure in a paper machine. This machine uses heat and pressure from rollers to take away the liquid from the pulp. As the pulp actions from the wet end to the dry end of the dispensation equipment, it is pressed to manually take away the bulk portion of the liquid. Forced heat is then used to evaporate the residual fluid, leaving dried, uncoated paper with fewer than 6% water content.

Uncoated paper is sometimes treated with extra sizing. The paper is given a thin coating of sizing materials that aid it in accepting ink extra readily or to add an exact finish to the paper. By adding coating to the paper, lofty gloss, matte, and semi-matte property can be achieved.

The product of the paper manufacturing procedure is a single continuous piece of paper. This finished paper is collected on reels for storage space or sent to a paper cutting machine. Reels of finished paper are used in the printing trade, while cut paper is often sold for use by customers.
