| Food-Grade Folding Boxboard | 230–400 gsm | 640 × 900 mm; 700 × 1000 mm; custom sheets or reels | White coated top side with a white or natural reverse side | Suitable only when the supplied grade, coating, inks, adhesives, and intended use comply with the destination market’s food-contact requirements | Dry-food cartons, bakery boxes, cereal cartons, confectionery sleeves, and takeaway packaging | Offset, flexographic, digital, and gravure printing, depending on coating and converting requirements | Food-contact declaration, migration test results, odor and taste testing, moisture resistance, and traceability |
| Coated One-Side Bristol Board | 200–350 gsm | Common commercial sheets from approximately 450 × 640 mm to 720 × 1020 mm | Gloss, silk, or matte coating on one side; uncoated reverse side | May be used for indirect-contact packaging when the complete packaging structure is compliant; not automatically food-safe | Product sleeves, paper bands, bakery inserts, menu cards, and secondary packaging | Excellent image reproduction on the coated side; suitable for offset and digital printing | Coating composition, rub resistance, folding performance, print-side requirements, and regulatory documentation |
| Uncoated Food-Grade Bristol Board | 180–400 gsm | Standard sheets, guillotine-cut sheets, and custom dimensions | Natural, smooth, or machine-finished surface | Can be suitable for direct or indirect food contact only with an appropriate grade and verified compliance documentation | Paper trays, dry-food cartons, bakery packaging, dividers, and food-service accessories | Offset, flexographic, letterpress, and digital printing; absorbs ink more than coated board | Absorbency, stiffness, fiber origin, cleanliness, odor, and performance after die-cutting and folding |
| Recycled Bristol Board | 250–600 gsm | Commonly supplied in standard industrial sheet sizes or made-to-order formats | Grey-back, white-back, coated, or uncoated surfaces | Generally more appropriate for secondary packaging unless a specific food-contact grade has been tested and approved | Outer cartons, transport sleeves, display packaging, separators, and non-contact food packaging | Offset and flexographic printing; surface uniformity varies by recycled fiber content | Recycled content percentage, de-inking process, odor, heavy-metal limits, stiffness, and sustainability certificates |
| Cupstock and Liquid-Packaging Board | 180–350 gsm | Reels and sheets sized for cup, carton, or pouch-converting equipment | Polymer-coated, dispersion-coated, or barrier-coated surface | Designed for approved liquid or food-contact applications when the coating and board combination meet applicable regulations | Paper cups, beverage cartons, soup containers, ice-cream packs, and chilled-food packaging | Flexographic, offset, and rotogravure printing, subject to coating and converting specifications | Barrier type, heat-sealing temperature, leakage resistance, coating weight, odor, and migration performance |
| Grease-Resistant Bristol Board | 230–450 gsm | Sheets or reels; dimensions depend on the intended die-cutting line | Uncoated, clay-coated, dispersion-coated, or specialty barrier finish | Suitable for food applications only where grease resistance and food-contact compliance are confirmed for the entire structure | Pizza boxes, pastry boxes, fried-food packs, sandwich cartons, and snack trays | Flexographic and offset printing; surface treatment can affect ink adhesion and drying | Kit or grease-resistance value, heat performance, moisture resistance, odor transfer, and folding-crack resistance |
| High-Stiffness Display Bristol Board | 350–700 gsm | Large-format sheets, mounted sheets, and custom die-cut blanks | Coated, laminated, embossed, or textured surface | Normally intended for secondary packaging or point-of-sale use unless an approved food-contact grade is specified | Counter displays, retail multipacks, shelf-ready packaging, and premium outer sleeves | Offset, digital, screen, and specialty finishing processes | Caliper, bending stiffness, flatness, scoring quality, lamination adhesion, and pallet stability |
| Custom-Converted Bristol Packaging Board | Specification-based; commonly 200–600 gsm | Die-cut blanks, folded cartons, reels, sheets, and customer-defined formats | Selected according to the package design: matte, gloss, uncoated, embossed, or barrier-treated | Depends on the board grade, inks, coatings, adhesives, and production process used for the finished package | Private-label cartons, bakery packs, takeaway boxes, subscription food packaging, and promotional packs | Printing and finishing are selected according to artwork, run length, and packaging machinery | Technical drawing approval, tolerance control, sample validation, batch consistency, packing method, and export documentation |
