Unbleached Kraft Liner Board Paper

Product Description

Unbleached kraft liner board is a durable paper grade manufactured for industrial packaging, corrugated box production, and protective wrapping applications. Supplied by PRGRI High Rich Paper, this material functions both as high-strength linerboard and as corrugating medium or fluting paper. It is engineered to deliver reliable burst strength, stiffness, and surface uniformity, making it suitable for automatic high-speed corrugators as well as sheet-fed conversion lines. The product is available in multiple pulp compositions to align with distinct functional, environmental, and regulatory requirements. Sourcing options include 100% virgin pulp derived from bamboo or wood fibres, semi-virgin blends, agro- and bagasse-based pulp, and 100% recycled paper stocks. Select grades come supported by FSC certification and food-grade compliance, enabling clean and safe utilization in direct or indirect food packaging. Packaging converters and manufacturers use this kraft paper across a broad spectrum of structural and flexible packaging applications. Typical end uses include outer liners and fluting medium for 3-ply, 5-ply, and 7-ply corrugated shipping cartons, heavy-duty industrial boxes, mono carton boxes, and pizza boxes. Beyond rigid boxes, the paper is suitable for converting into shopping bags, grocery bags, multiwall cement sacks, pouches, and substrates intended for coating, lamination, or protective wrapping. Technical versatility is reflected in its extensive specification spread. The paper is produced across substance weights ranging from 40 GSM up to 350 GSM, with a wide burst factor (BF) capability spanning 18 BF to 40 BF. Depending on printability and friction requirements, converters can select either machine glazed (MG) surfaces for enhanced smoothness or machine finished (MF) surfaces for standard runnability. Visual shade selections encompass natural brown, dark brown, reddish brown, light golden yellow, dark golden yellow, black, and bleached white. When procuring this material, industrial buyers must evaluate technical matching parameters. Mill deckles vary across production schedules, requiring buyers to align reel widths with available machine deckle sizes ranging from 208 cm up to 520 cm to minimize trim waste. Commercial pricing and minimum procurement quantities vary by order tier and specification: the source lists an entry price of ₹ 39/Kg alongside a specification-dependent range of ₹ 42 to ₹ 58/Kg. Domestic fulfillment requires a minimum order quantity starting at 9,000 Kg (or full 10-ton truckload lots), while export shipments are supplied in standard 20-foot or 40-foot full container loads (FCL).
