| Bag Capacity | Choose dimensions according to the largest common product set. Common retail formats range from approximately 180 × 90 × 250 mm for small items to 450 × 170 × 500 mm for larger products. | Small, medium, large, extra-large, or custom dimensions. | Correct sizing reduces paper consumption, product movement, and the need for double-bagging. | Create a size matrix covering at least 90% of expected product orders before requesting quotations. |
| Paper Weight | Approximately 80–120 gsm for light retail goods; 120–170 gsm for general-purpose shopping bags; 170–250 gsm for heavier or premium applications. | Kraft paper, white kraft paper, recycled paper, or mixed-fiber paper. | Higher basis weight usually improves stiffness and carrying strength but increases material use, shipping weight, and cost. | Use the lowest paper weight that passes the required load, drop, and handle tests. |
| Paper Fiber Content | Specify virgin fiber, post-consumer recycled fiber, or a controlled blend. Recycled content should be stated as a percentage by weight and verified through supplier documentation. | Virgin kraft, recycled kraft, or blended paper grades. | Fiber selection affects strength, appearance, printability, recycled content claims, and regional recycling expectations. | Set a documented recycled-content percentage where product performance and local regulations permit. |
| Handle Design | Twisted-paper handles suit most standard shopping bags. Flat-paper handles provide a broader grip, while die-cut handles can reduce components but may need reinforced rims. | Twisted paper, flat paper, cotton or synthetic cord, and die-cut paper handles. | Handle type affects comfort, assembly, failure risk, material compatibility, and recycling simplicity. | Prefer paper-based handles for a mono-material structure unless load or comfort testing requires another option. |
| Load Performance | Define a rated carrying load for each size. Practical internal targets often range from 3–5 kg for light bags and 8–12 kg for reinforced heavy-duty bags. | Standard bottom construction, reinforced base, folded rim, and handle patches. | Load performance depends on paper strength, gusset geometry, adhesive quality, handle attachment, and bottom construction—not paper weight alone. | Approve production only after filled-bag load testing under dry and humid conditions. |
| Moisture Resistance | Use uncoated paper for ordinary dry goods. For humid environments, evaluate wet-strength paper or a suitable water-resistant treatment without compromising the intended disposal route. | Uncoated paper, wet-strength paper, water-based coating, or limited barrier treatment. | Humidity can reduce paper strength during sea freight, warehouse storage, and retail use. | Define a maximum storage humidity and require packaging tests that simulate the destination climate. |
| Print Coverage | Specify one-color, spot-color, or full-color printing. Keep total ink coverage appropriate for the paper grade and intended recycling pathway. | Flexographic, offset, or digital printing, depending on volume and artwork complexity. | Print coverage influences visual quality, lead time, minimum order quantity, ink usage, and recyclability considerations. | Use water-based or otherwise documented ink systems and approve a physical color sample before mass production. |
| Surface Finish | Uncoated surfaces provide a natural appearance and generally simplify recycling. Laminated or heavily coated surfaces should be used only when there is a clear functional requirement. | Natural uncoated, matte water-based coating, gloss coating, or film lamination. | Finishes change appearance, scuff resistance, moisture performance, recyclability, and packaging cost. | Prioritize recyclable, repulpable, or fiber-compatible finishes and request technical evidence for environmental claims. |
| Product Safety and Compliance | For ordinary retail packaging, define requirements for restricted substances, inks, adhesives, heavy metals, and relevant destination-market packaging rules. | Supplier declaration, test report, restricted-substance specification, and batch records. | Requirements differ by destination, product category, and whether the bag may directly contact food or other sensitive products. | Prepare one compliance checklist per destination market and link every claim to current documentation. |
| Sustainability Evidence | Request verifiable information on fiber origin, recycled content, production controls, packaging waste, and end-of-life characteristics. | Chain-of-custody documentation, recycled-content evidence, mill declarations, and third-party test reports. | Environmental claims should be specific, traceable, and relevant to the market where the bags will be sold. | Avoid vague claims such as “eco-friendly”; define measurable claims such as recycled content, fiber source, or recyclability conditions. |
| Order Quantity | Minimum order quantities vary by paper grade, printing method, size, handle type, and tooling. Custom printed production commonly requires a higher minimum than plain stock. | Trial order, pilot batch, standard-size stock, or full custom production. | Order quantity affects unit cost, inventory exposure, print setup allocation, and the feasibility of multiple sizes. | Compare total landed cost at pilot, standard, and volume quantities rather than comparing unit price alone. |
| Lead Time | As a planning benchmark, allow approximately 2–4 weeks for sampling and 4–8 weeks for production after artwork and specifications are approved; international transit is additional. | Supplier production schedule, port availability, consolidation, and destination delivery. | Seasonal demand, port congestion, customs clearance, and quality rework can extend the overall replenishment cycle. | Build a safety-stock policy around the complete order-to-delivery cycle, not only factory production time. |
| Shipping Efficiency | Evaluate packed volume, bag nesting, carton dimensions, gross weight, pallet configuration, and container utilization. | Flat-packed bags, nested bundles, export cartons, palletized loads, or mixed-size shipments. | Paper bags are lightweight but can occupy substantial cubic volume, making freight efficiency important to landed cost and emissions. | Request a carton-packing diagram and calculate cost per usable bag after freight, duties, handling, and loss allowance. |
| Quality Control | Inspect dimensions, paper weight, print registration, color, handle attachment, bottom bonding, moisture condition, carton count, and visible defects. | Pre-production sample, first-article approval, in-process inspection, pre-shipment inspection, and arrival inspection. | Small variations in gusset width, adhesive application, or handle placement can affect usability and stacking consistency. | Use an agreed acceptance standard with measurable tolerances and retain approved samples for comparison. |
| Supplier Resilience | Assess production capacity, equipment redundancy, raw-material sourcing, quality systems, export experience, contingency planning, and communication response time. | Single-source, dual-source, regional backup, or approved supplier panel. | Paper prices, energy costs, transport disruption, and seasonal capacity constraints can affect continuity and margin. | Qualify at least one backup production route for high-volume or business-critical bag formats. |
| Total Landed Cost | Calculate unit price plus sampling, tooling, packaging, inland transport, international freight, insurance, duties, customs fees, inspection, storage, and expected waste. | EXW, FOB, FCA, CIF, or delivered-cost comparisons, depending on the purchasing model. | A lower factory price may be offset by higher freight volume, additional handling, defects, or import costs. | Select the specification with the best balance of performance, compliance, sustainability evidence, and landed cost. |
