18pt Cardstock — The Universal Standard for Retail Folding Carton Packaging
18-point (0.018") coated white cardstock — the industry-standard specification for the majority of retail folding carton packaging across consumer categories.
Why Choose 18pt Cardstock
About 18pt Cardstock
18pt cardstock is the default material specification for retail folding carton packaging — the board weight at which structural performance, print quality, and material cost are optimally balanced for the widest range of consumer goods applications. When a packaging specification says 'standard retail carton board,' it means 18pt coated white SBS or CRB. The majority of consumer goods packaging on retail shelves globally is produced on 18pt board.
18pt provides the structural rigidity required for standard retail carton sizes to maintain shape under shelf stacking, resist panel bowing, and perform reliably in automated filling equipment. It is the board weight that cartoning machine engineers design their equipment around — consistent enough for reliable performance across production runs.
Why 18pt Became the Industry Standard
18pt SBS became the retail carton standard through decades of optimization across the packaging supply chain. Brand owners found it provided adequate structural rigidity for standard retail carton sizes. Cartoning machine manufacturers calibrated their equipment to 18pt board dimensional characteristics. Printers optimized their processes for 18pt sheet handling. Converters standardized their die specifications around 18pt thickness. This system-wide calibration creates efficiencies across the supply chain that favor 18pt for all standard applications.
18pt for Different Packaging Categories
18pt SBS is appropriate for the vast majority of cosmetic cartons (foundation, serum, moisturizer), pharmaceutical cartons (OTC medications, supplements), food cartons (tea, coffee, cereal, snacks), and general consumer goods packaging. 14pt is appropriate when boxes are small and compact; 24pt is appropriate when boxes are large, heavy-duty, or require maximum premium feel. 18pt handles everything between these extremes.

18pt Cardstock FAQs
Is 18pt the right choice for my packaging?
18pt is appropriate for most standard retail folding carton sizes. If your box dimensions are smaller than approximately 3x2x1 inches, 14pt may be sufficient. If your box is taller than 8 inches with long unsupported panels, 24pt may be needed. Our structural team will confirm the right specification for your specific dimensions.
What is the difference between 18pt SBS and 18pt CRB?
18pt SBS uses virgin bleached fiber — brightest printing, consistent caliper, food-contact pure. 18pt CRB uses recycled fiber with a clay-coated front — slightly lower brightness, good print quality, sustainable credentials. Performance is comparable for most applications; specification depends on brand priorities.
Can 18pt cardstock be used for automated high-speed packaging?
Yes. 18pt is the specification that most automated cartoning equipment is designed around. Consistent caliper — a characteristic of premium 18pt SBS — is critical for reliable automated performance.
What printing quality can I expect on 18pt cardstock?
Full photographic print quality with accurate CMYK and Pantone color reproduction. 18pt SBS provides the same print surface as all other SBS calipers — consistent clay coating independent of board thickness.
What is the minimum order for 18pt cardstock packaging?
18pt cardstock packaging starts at 100 units with digital printing. Offset printing from 500 units.
