Paper Making

Papermaking is the process of making paper, a material which is used universally today for writing and packaging.

Processes
In papermaking, a dilute water based suspension of fibres is filtered through a screen, to produce a mat of randomly interwoven fibres. Excess water is removed from the fiber mat by pressing and drying, making paper. Since the invention of the Fourdrinier machine in the 19th century, most paper has been made from wood pulp because of cost. But other fibre sources such as cotton and textiles are used for high-quality papers. One common measure of a paper's quality is its non-wood-pulp content, e.g., 25{bae455710082ffc188be46a81919e0436c70756a3753dc21b8bd47cd33e92f3b} cotton, 50{bae455710082ffc188be46a81919e0436c70756a3753dc21b8bd47cd33e92f3b} rag, etc. Previously, paper was made up of textile rags, hemp and other materials.

Our Products
We have several products which specifically address paper mill technical problems to improve the paper making processes.

Oil & Grease Resistant Agent

Our products are FDA and BFR compliant, approved for food contact, and environmentally green chemicals for employment in the production of Greaseproof paper.

Greaseproof paper is paper that impermeable to oil or grease and is normally used in cooking or food packaging. It is used for wrapping foods for storage, especially greasy foods such as butter, bacon or doughnuts, and is also used to separate layers of pancakes, cookies or other baked goods for storage.

Enzymatic Refining

It is well known that refining pulp fibers prior to the final papermaking process results in improved sheet formation and a number of beneficial sheet properties such as higher density, higher tensile strength, and resistance to burst. These enhancements of sheet properties are accomplished by changes in the individual fibers due to the mechanical treatment utilizing our products.

With our enzymatic technology product solutions, papermakers can gain benefits through improvements in overall efficiency in refining both virgin pulp and recycled fibers to improve quality parameters, fine-tune processes, and achieve value-added product characteristics. Application of selected Endo-glucanases will open the fiber surface, creating fibrillation at lower energy levels and yielding less damage to the fiber.

This technology will either lower the refining energy and/or optimize paper strength properties, which can improve overall machine run-ability.

Enzymatic Drainage

Recycled paper does not have to be low quality, at least not when employing enzymatic drainage improvements and value-added fiber modification. Advancements in the recovery, separation, and processing of recovered fibers has significantly improved global recycling efforts. However, the increasing demand for recycled paper has also increased competition for feed stock supplies to the papermaking process.

Our enzymatic technology solutions improve the quality of the recycled paper finishes, and delivers efficient process conditions that include a package of benefits such as:

  • Drainage improvement,
  • Machine run-ability improvement, and
  • Steam usage reduction in the dryer section.

Enzymatic Sticky and Pitch

Recycled fiber is a major source of raw material for the modern recycled paper mill. Stickies in the recycled fiber feed stock are a major obstacle in papermaking because they tend to deposit on machine surfaces, fabrics, wires, felts, and rolls, which leads to run-ability and maintenance problems such as paper breaks at the press. If not controlled, this extraneous stickies can also lead to paper quality issues such as holes, sheet defects, and high dirt counts.

Our enzymatic technology solution efficiently converts the adhesive waste into more manageable components, thereby improving machine performance and also improving the recycled paper quality in terms of spots, holes, and breakage while as well as preventing machine damage.

Starch Conversion Enzyme

Sizing improves the printing surface of the paper, making it more receptive to inks and resistant to abrasion. Starch modification addresses this issue and is therefore an important step in the production of a quality paper product.

Our biodegradable enzymatic technology solutions replace aggressive oxidizing agents by modifying starch in-house to obtain higher quality starch sizes, ensuring control over process solution viscosity.

Primer coating for Digital Printing on paper substrate

Primer Coating is a product that can be added to size press treatments or pigments Coating to optimize substrates for HP Indigo printability. This product provides excellent adhesion of HP Indigo Electroinks® to paper. Its low pH allows incorporation into a wide range of formulations.

Paper Machine Defoamer

Paper machines are very sensitive to small foam-related problems. Closed-loop circulation white water systems and the use of chemical additives can lead to increased foam generation in papermaking systems. Foam causes quality issues by decreasing production output and final paper quality.

Our line of defoamer products are designed to fully meet the needs of our customers in the paper industry. Combining the best-designed products with a full understanding of paper mill process requirements and superior technical application knowledge delivers a cost effective strategy for mill improvement to our customers.

Our defoamers ensure superior deaeration, drainage and cost effectiveness over many conventional water based defoamers.

Bulking Agent

Bulking agents enable the production of paper with higher thickness and bulkiness from a much lower amount of virgin pulp, contributing to substantial savings of raw material. In addition, it also provides a good hand-feel for tissue paper products.

Our defoamers ensure superior deaeration, drainage and cost effectiveness over many conventional water based defoamers.

Surface Strength (External Dry Strength) Agent

Surface strength agents are commonly used to enhance surface strength of fine paper, coated paper, coated board, linerboard, newsprint, etc. It will also improve bonding strength, sizing degree and can reduce fuzz that sometimes appears on the paper surface after printing.

Surface strength is used to describe the strength between a paperboard's coated surface and its inks, varnishes or films, or the strength as measured perpendicular to a level just underneath the surface.

Internal Dry Strength Agent

Strength additives are critical components in the manufacturing of board and tissue. They enhance not only the required strength and quality to paper products, but can also improve machine productivity and process efficiency.

IDS agents improve the tensile strength and burst factors of paper, even in furnishes using mechanical and thermo-mechanical pulps. They enhance fiber-fine and fiber-fiber interactions in the sheet, which improves sheet inter-layer bonding strength.

External Surface Sizing Agent

Surface sizing agents are used to increase the hydrophobic nature of paper and board, so as to reduce liquid penetration and improve toner adhesion and ink jet printability. They also improve the surface properties of board and paper, and virtually eliminate internal sizing agent with the main effect to improve the runability of the paper making machinery.

IDS agents improve the tensile strength and burst factors of paper, even in furnishes using mechanical and thermo-mechanical pulps. They enhance fiber-fine and fiber-fiber interactions in the sheet, which improves sheet inter-layer bonding strength.

Internal Sizing Agent

Internal size agents are used to make the paper web hydrophobic, improve dewatering and retention of fillers & fibers in the paper sheet.

Our Internal Sizing agent is less dependent on aluminum sulfate and is capable of sizing over a wide pH range, thus the paper produced is not brittle or yellow as occurs in a more acidic paper making process.

Wet Strength Agent

Certain kinds of paper such as tissue and liner board are required to retain their strength after complete rewetting. This is accomplished by the addition of wet strength resins during the production process.

Wet Strength Agents can improve wet strength without reducing absorbency of paper, while increasing tear strength, improving abrasion resistance of paper, and improving retention of fillers and fines. They also assist in improving drainage, drying, dry strength and formation, and may be employed as a replacement for urea-formaldehyde and melamine-formaldehyde wet-strength resins.

Modified Tapioca Starch

Paper grade modified tapioca starch has many applications and usages to the paper making process such as paper and surface strength improvement, enhanced drainage and retention aid.
