SBS partitions are widely used for interior packaging applications, including partitions, pads, inserts, and specialty die cutting for folding carton systems. The clean, bright surface makes SBS ideal for white sanitary box dividers and medical grade partitions in healthcare, pharmaceutical, cosmetic, and food packaging environments. Available in a range of calibers and finishes, SBS can be specified based on product requirements, industry standards, and shipping conditions.
Solid Bleached Sulfate, (SBS) combines all the benefits of chipboard with a specialized coating that enhances performance for modern packaging needs. This bleached white board is produced from premium pulp fibers, creating a smooth, consistent surface with a far more aesthetically pleasing look.
Solid Bleached Sulfate is available in a wide range of calibers, or board thicknesses, measured by grammage and density. Standard SBS partition board calibers typically range from .010″ to .024″ across most finishes. That said, Box partitions are most frequently made using .024 SBS regardless of the finish.. Clay coated one side SBS partition paper is also used by folding carton manufacturers. . We can also use .018 SBS for layer Pads but we prefer to stay at .024 on all interior box partitions.These thickness options allow for precise cell sizing while maintaining structural integrity, structural stiffness, and reliable performance in partition designs. All standard SBS calibers are stocked to support efficient production timelines and consistent manufacturing schedules.
Unlike corrugated options, SBS partitions are available in multiple finishes, each offering distinct functional and visual advantages. Finishes include Clay Coat SBS, Poly Coat, and Milk Board, all engineered to reduce lint, protect product surfaces, and deliver a smooth, clean interior presentation. These finishes make SBS an ideal material for white sanitary box dividers used in sensitive packaging environments. CertainSBS finishes such as Milkboard are approved for close contact with food and frozen food applications due to their FDA approved coatings.
Stamping, and embossing are available across all finishes to allow for part numbers or other identification to be added to the finished product. Helping to support premium packaging goals. Poly Coat and Milk Board also provide added resistance to moisture and grease, while also providing a scratch resistant packaging application.
SBS partitions offer optional features that enhance performance and ease of use, especially in precision packaging of applications requiring medical grade partitions. Available features include locking dies, S notches,corner cuts and half moon dies to improve overall useability, product accessibility and smooth carton insertion. Locking dies reinforce intersection points for added durability during shipping, while half moon cuts allow quicker product access to support efficient warehouse handling. Stamping for logos, recycling marks, or handling instructions is available on all SBS partitions and pads.
SBS partitions are well suited for awkward product shapes, fragile items, and high visibility packaging where both protection and presentation matter. Partitions can be manufactured to fit standard cartons or custom box designs. Air cell layouts can be incorporated along the perimeter to improve cushioning and reduce product contact. Partition lengths range from 1″ to 36″, with heights from 13/16″ to 12″. Cell sizes can be produced as small as 3/8″ x 3/8″ for precise product separation. Our engineering team supports new pack development, updates to existing designs, and ongoing packaging optimization. All above sizes and capabilities are dependent upon each specific partition design.
Each SBS partition is shipped pre-assembled, and collapsed for efficient pallet loading and warehouse storage. Partitions are packed in corrugated cartons and labeled with description, quantity, customer information, manufacturing date, and any additional markings requested.
Our manufacturing capabilities are built around precision, consistency, and scalability. From raw bleached paperboard stock to finished folding box inserts, SBS partitions are produced through advanced die-cutting, and slotting processes. This process allows us to support industries that demand clean packaging, tight tolerances, and repeatable quality, including the pharmaceutical industry and regulated packaging environments such as the Glass industry.
SBS paperboard is widely used in applications where appearance, cleanliness, and performance matter. Compared to plastic or lower-grade fiberboard, solid bleached sulfate partitions offer a balance of strength, clean white presentation, and recycling compatibility. SBS board and box inserts integrate seamlessly into folding carton systems and premium packaging designs while supporting paper recycling programs and environmentally friendly packaging initiatives.
Every SBS partition project begins with collaboration. Our team works closely with each customer to evaluate product requirements, transport conditions, and packaging goals. From prototype development to full production, we provide design support that improves performance, reduces waste, and aligns with brand standards. Our warehouse inventory and manufacturing flexibility allow us to support both short runs and high-volume programs with consistent quality at competitive pricing levels that come straight from the manufacturer.
In the automotive industry, part integrity isn’t optional. Whether components are moving between plants, heading to Tier 1 suppliers, or shipping directly to OEM facilities,
