Description
Single Wall Corrugated Sheets are lightweight protective packaging materials designed for cushioning, void fill, and product separation in shipping boxes and storage containers. These 12″L x 24″W kraft sheets are ideal for businesses that need dependable, cost-effective corrugated packaging solutions in bulk quantities.
Each sheet features a single-wall construction with a fluted corrugated layer sandwiched between two kraft paper liners, delivering the optimal balance of protection, weight, and material cost. The 12″ x 24″ dimensions offer versatile sizing for standard shipping applications, while the 50-pack quantity ensures adequate supply for mid-to-large volume operations. Kraft paper construction provides natural grease and moisture resistance, making these sheets suitable for food packaging, electronics, automotive parts, and general merchandise protection. The corrugated fluting pattern absorbs shock and vibration during transit, reducing product damage claims and customer returns. Single-wall construction offers superior stiffness compared to tissue or foam alternatives while maintaining minimal dimensional weight charges for carriers using dimensional weight pricing models. These sheets are recyclable and compostable, aligning with sustainability initiatives and green packaging certifications required by many enterprise buyers.
Manufacturing facilities, e-commerce fulfillment centers, distribution warehouses, and retail shipping departments rely on corrugated sheets for box liners, product wrapping, and inter-layer separation. Food service businesses use them as food-grade packaging inserts for bakery items, produce, and prepared foods. Industrial suppliers leverage these sheets for protecting machinery components, metal parts, and delicate electronics. Small manufacturers and custom packaging operations cut sheets to specific dimensions for product-specific protective packaging. Logistics companies and third-party logistics (3PL) providers stock them for on-demand packaging solutions. Any operation requiring scalable, economical packaging protection across high-volume shipments benefits from bulk corrugated sheet inventory.
When selecting corrugated sheets, evaluate flute profile (A, B, C, or E flute), which determines cushioning capability and stacking strength—single-wall sheets typically feature B or C flute for balanced performance. Verify that kraft paper meets your food contact requirements if packaging edibles or beverages. Confirm burst strength and edge crush test (ECT) ratings to ensure the sheet weight supports your specific product and stacking height. Consider roll vs. flat-sheet format based on your cutting and handling equipment. Assess moisture barrier properties if products will encounter humidity or condensation during storage or transit. Compare basis weight (pounds per ream) across suppliers, as this directly impacts durability and cost-per-unit metrics. Order sample quantities before committing to large-volume purchases to verify compatibility with your packing processes and machinery specifications.
What size are the individual sheets, and can they be cut to custom dimensions?
Each sheet measures 12 inches in length by 24 inches in width. While we supply them at this standard dimension, most corrugated sheets can be cut using utility knives, box cutters, or guillotine-style cutting equipment to fit your specific packaging needs. Some customers pre-cut sheets in-house to match product dimensions, while others use them at full size as box liners or void fill material. We recommend testing your cutting methodology before processing your entire order.
How does single-wall corrugated compare to double-wall corrugated, and when should I use each?
Single-wall corrugated features one fluted layer between two kraft liners, while double-wall construction includes two fluted layers with a middle kraft layer, offering significantly greater stiffness and crush resistance. Single-wall corrugated is ideal for lightweight products, short-distance shipping, and cost-sensitive applications where maximum cushioning isn’t required. Double-wall corrugated suits heavy items, long-haul shipping, multi-level stacking, and products requiring enhanced puncture resistance. Single-wall typically costs 40-50% less per unit and weighs substantially less, reducing dimensional weight charges. Your product weight, fragility, shipping distance, and stacking requirements should determine which construction meets your needs and budget.
Are these kraft sheets food-safe for direct product contact?
Kraft corrugated sheets are generally food-contact compliant when manufactured according to FDA and USDA standards, making them suitable for bakery items, dry goods, produce, and non-fatty foods. However, kraft paper alone provides limited grease barrier protection—foods with high oil content (cheese, nuts, fatty meats) may require coated or wax-lined sheets. We recommend verifying the specific food contact certifications for your intended application and confirming compliance with local food safety regulations.
