Starch For Paper

Description

The starch used in the paper making industry is mainly to increase the bonding strength of plain white paper and paperboard. It improves the strength, paper quality, and also brightens it. BCS Global Innovation supplies some of the most economical starches to increase the strength of paper.

Cationic Starch

Cationic starch is a fibre-retaining and optical brightening agent. It increases the paper sheet strength. This starch helps in enhancing paper strength, water drainage, retention, improves paper quality, and reduces dusting, lining, and size addition. Cationic starch serves as both a fiber-retaining and optical brightening agent in the paper-making process. Its specific applications include enhancing the paper sheet strength, improving water drainage, and increasing retention. This starch type also helps reduce dusting, lining, and size addition during paper production. While cationic starch offers these benefits, it is essential to note that excessive usage may lead to increased costs and potential negative effects on paper properties.

Oxidized Starch

Oxidized starch exported by BCS Global Innovation is one of the most common modified starches used in surface sizing because of its good film-forming characteristics and reduced tendency to retro-gradation. It improves the quality of paper and cardboard made from primary and secondary semi-finished products. Oxidized starch possesses excellent film-forming characteristics, contributing to better quality for paper and cardboard products. Compared to other starch types, oxidized starch exhibits reduced retro-gradation tendencies, which means it retains its properties for a longer time. However, it is important to control the amount used, as excessive application might result in reduced paper strength and higher sizing material costs.

Spray Starch

BCS Global Innovation manufactures spray starch, used as an adhesive in ply bond multi-layer board paper. It improves the internal bonding strength of the paper. This technique, which is intermediate between wet end addition and surface sizing, is an economical way to enhance the strength of paper. Spray starch application is crucial for improving bonding strength efficiently, but optimization of the spraying process is essential to avoid overuse, which could cause uneven bonding and increased production costs.

BF-Bond PAP

BF-Bond PAP is a modified starch formulation from BCS Global Innovation, specifically designed to provide excellent surface coating and strength in kraft paper. This starch offers improved surface finishing to the paper and enhances its printability. To achieve optimal results, it is crucial to follow recommended usage guidelines, as excessive BF-Bond PAP application might negatively affect the paper’s appearance and print quality.

Thin Boiling Starch

Thin boiling starch is a modified starch formulation with controlled viscosity and extra-strong film properties, offered by BCS Global Innovation. It finds wide application in the field of paper (coating and sizing). Thin boiling starch helps improve wax pick, gloss, and smoothness of the paper by forming a strong and flexible film on the fibres. Proper management of the boiling process is important to avoid undercooking or overcooking, which may impact the starch’s performance and overall paper quality.
