Collect the package identity and drawings
Record bag supplier, product code, nominal format, fitment drawing, closure type and supporting container. Include target fill mass, handling method and traceable packaging lot information. Keep revisions of drawings so purchasing changes remain visible.
Send this file to the filler supplier before model or head selection. Ask which dimensions, materials and preparation details must be confirmed. A visual resemblance or the same nominal volume is insufficient evidence of a compatible interface.
Confirm the complete combination
The written confirmation should identify the bag, fitment and configured filler, together with the package handling and closure method. State whether the upstream product connection and sterile pathway are in the same supplier scope or require integration with others.
Manufacturer catalogs establish filling equipment families, but the actual package combination needs its own review. Confirm utility and operating requirements for package changes using the selected model documents.
| Item | Document / confirmation |
|---|---|
| Bag | Supplier, product code, format and revision |
| Fitment / closure | Drawing, dimensions, preparation and closure method |
| Filler | Configured head and written package compatibility |
| Handling | Support container, loading, removal and transport instructions |
| Acceptance | Package-integrity method, lot records and change control |
Agree integrity and handling checks
The packaging supplier and process team should establish the appropriate inspection and package-integrity criteria. Include closure, fitment condition and handling damage as relevant to the actual package system. Distinguish equipment demonstration from final process validation.
Assess the complete filling cycle: loading, connection, product fill, closure and removal. The resulting completed-package rate may differ from product flow during filling. Review the upstream response during package changes.
Treat substitutions as a documented change
A new bag supplier, fitment revision or closure component can change the interface even where volume and commercial description stay the same. Route substitutions through the compatibility and validation review before using them in production.
Keep the final approved combination with the spare-parts and operating records. If bulk aseptic pulp is later opened for conventional repacking, establish the new hygiene and preservation boundary separately; the original package approval does not cover that operation.
Questions from equipment buyers
Are two bags of the same size interchangeable?
No. Fitments, closures, materials and preparation methods can differ. Confirm the exact combination.
Who confirms compatibility?
The project should obtain package documentation and written confirmation from the relevant bag and filler suppliers, with integrated process responsibility assigned.
Does package approval validate the pulp process?
No. Package integrity is one part of a complete product-treatment and sterile-handling system.
