| 1 | Customization Capability | Body construction, filling and discharge design, liner type, lifting loops, fabric coating, dimensions, safety factor, antistatic options, and closure configuration. | Required Written technical specification with tolerances for dimensions, fabric weight, loop position, inlet, outlet, and liner fit.
Preferred Prototype or pre-production sample approval before mass production. | Approved drawing, bill of materials, sample inspection report, change-control procedure, and records showing that customer specifications are transferred to production documents. |
| 2 | Pharmaceutical-Grade Testing | Mechanical performance, seam strength, safe working load, safety factor, antistatic behavior, liner integrity, cleanliness, and compatibility with the intended product. | Required Lot-based testing against the agreed specification and applicable packaging requirements.
Preferred Documented test methods, calibrated equipment, defined sampling plans, and retained test records. | Certificate of analysis, test reports linked to production lots, equipment calibration records, sampling plan, nonconformance procedure, and cleanliness inspection results. |
| 3 | Material and Liner Control | Virgin or recycled resin policy, polypropylene fabric grade, liner film structure, additives, antistatic materials, food-contact or pharmaceutical-contact suitability, and foreign-matter controls. | Required Full material specification and documented approval of every material in contact with the product.
Preferred Supplier qualification, incoming inspection, and controlled material identification. | Material declarations, resin or film specifications, incoming inspection records, safety data where applicable, approved-supplier list, and written controls for material substitutions. |
| 4 | Traceability and Batch Records | Ability to trace finished FIBCs to raw materials, production date, machine or line, operators, inspection results, packaging records, and shipment information. | Required Unique lot or batch identification maintained from incoming material through delivery.
Preferred Electronic or searchable records with defined retention periods and rapid recall capability. | Sample batch record, lot-numbering format, raw-material certificates, production travelers, final inspection records, packing list, and recall or mock-recall procedure. |
| 5 | Quality System and Clean Manufacturing | Quality responsibilities, document control, personnel training, hygiene rules, pest control, foreign-material prevention, cleaning procedures, deviation handling, and corrective actions. | Required Controlled procedures for inspection, deviations, complaints, corrective actions, and document changes.
Preferred Dedicated clean production zones and risk-based contamination-control measures. | Quality manual, internal-audit schedule, training matrix, cleaning records, environmental or housekeeping inspection records, complaint log, corrective-action examples, and facility-audit report. |
| 6 | Production Capacity and Delivery Reliability | Monthly output, production lines, critical-process capacity, lead time, minimum order quantity, peak-season planning, production scheduling, and business-continuity arrangements. | Required Capacity figures supported by production records rather than sales estimates.
Preferred Defined lead-time range, backup equipment or qualified subcontracting controls, and documented contingency planning. | Capacity statement, recent on-time-delivery data, production schedule example, staffing plan, equipment list, maintenance records, inventory policy, and business-continuity plan. |
| 7 | Documentation and Customer Support | Technical communication, change notification, specification review, complaint response, regulatory documentation, export documentation, sample management, and after-sales support. | Required Controlled approval process for specifications, artwork, labels, certificates, and customer-requested changes.
Preferred Defined response times for complaints, deviations, and documentation requests. | Document-control procedure, change-notification template, complaint-response workflow, sample approval record, certificate format, contact escalation list, and previous anonymized corrective-action report. |
