Direct answer
Classify the supply and filling path before comparing RFQs
Printed rollstock and premade pouches describe different supply and filling paths. A rollstock RFQ should identify the web and filling-equipment inputs used to form and seal the package. A premade-pouch RFQ should identify finished dimensions, the filling opening and requested closure or feature positions.
Ask the equipment supplier or co-packer to confirm the filling-path requirements, and ask Minghua Pack to confirm in writing whether the requested supply format is within its current scope. This guide does not confirm that Minghua Pack supplies every format. Neither path by itself proves machine fit or finished-pack performance.
The RFQ inputs that change with the supply form
Use the comparison below as a classification aid, not as a ranking. It does not establish cost, order minimum, timing, equipment compatibility or technical performance for either path.
Supply form
Printed rollstock
A printed web is wound on a core and supplied for a form-fill-seal path.
Premade pouch
Individual converted pouches are supplied with the requested filling opening or side identified.
Filling path
Printed rollstock
The buyer’s equipment forms and seals the package from the web during filling.
Premade pouch
The buyer’s process fills an already converted pouch and completes the required closure or seal.
Equipment inputs
Printed rollstock
Provide the machine specification, web width, repeat, unwind direction, eye-mark information, core and roll limits.
Premade pouch
Provide the filling opening, handling and closing process, plus any equipment or co-packer specification that affects the finished pouch.
Artwork reference
Printed rollstock
Review artwork against the print repeat, eye mark, unwind direction and registration plan.
Premade pouch
Review artwork against the dieline, seal areas, filling opening and requested feature positions.
Confirmation path
Printed rollstock
The equipment supplier or co-packer confirms the machine inputs; the packaging supplier confirms the quoted supply scope.
Premade pouch
The filling or closing party confirms its handling inputs; the packaging supplier confirms the quoted converting scope.
Printed rollstock
Inputs for a rollstock RFQ
Begin with the specification the filling-equipment supplier or co-packer expects to receive. Mark any value that is provisional instead of treating it as confirmed.
- Machine make, model and the applicable equipment specification or drawing
- Required web width, print repeat and unwind direction
- Eye-mark position, registration reference and any coding area
- Core specification and maximum roll diameter accepted by the buyer’s equipment
- The buyer’s filling and sealing process inputs that the equipment supplier or co-packer has confirmed
- Current roll drawing, approved sample or existing specification when available
Premade pouch
Inputs for a converted-pouch RFQ
Describe the finished pouch and how the buyer or co-packer will fill and close it. The packaging supplier still needs to confirm the requested converting scope.
- Requested finished pouch style and finished dimensions
- Filling side or opening and the process used to complete the final closure or seal
- Fill amount, product form and any handling detail that affects the requested pouch geometry
- Requested zipper, tear notch, hang hole, spout or other feature position, if relevant
- Dieline, seal areas, coding area and artwork status
- Current pouch sample, drawing or existing specification when available
What to ask the equipment supplier or co-packer
The equipment supplier or co-packer is the source for the filling-path inputs its process requires. Ask for the applicable machine specification, accepted supply form, roll or pouch handling limits, filling opening, closing method and approval steps. If it controls the filling process, ask it to review the proposed packaging specification before the buyer approves it.
Providing those inputs to a packaging supplier supports an RFQ review; it does not establish equipment compatibility. Co-packing is outside this guide and should not be inferred as a Minghua Pack service. The requested supply format remains subject to written factory confirmation.
Match the artwork handoff to the format
For printed rollstock
Review the artwork with the print repeat, eye-mark position, unwind direction, registration reference, seal path and any coding area. The equipment specification determines which orientation and repeat inputs belong in the RFQ.
For premade pouches
Review the artwork with the pouch dieline, finished dimensions, seal areas, filling opening and requested feature positions. Identify which edge remains open for the buyer’s filling and closing process.
An artwork review confirms the print reference being discussed; it does not replace machine, seal, packed-product or finished-package validation.
Keep scope confirmation and validation separate
Step 1
Confirm the requested supply form
Ask Minghua Pack to state in writing whether the requested rollstock or converted-pouch format is within the current scope for the quoted specification.
Step 2
Confirm the filling-path inputs
Ask the equipment supplier or co-packer to confirm the machine, web, pouch-handling and closing requirements that belong in the RFQ.
Step 3
Align the artwork reference
Use the applicable repeat or dieline and identify seals, openings, eye marks, registration references, coding areas and requested features before approval.
Step 4
Define project validation
The buyer and the responsible filling or equipment parties should define the line, seal and finished-pack checks needed for the actual product and process.
A short checklist before sending the RFQ
- Requested supply form, or a clear note that it is not yet decided
- Packed product, product form and intended fill amount
- Filling path and the party responsible for filling and closing
- Machine or co-packer inputs that have been confirmed
- Roll specification or finished-pouch dimensions, as applicable
- Artwork status, number of designs and reference files
- Estimated quantity and SKU count as quotation inputs
- Destination and document needs for supplier review
- Existing drawings, specifications or representative samples
- Unknown items that still require written confirmation
If the supply form is still undecided, send the current filling-path information and mark the decision as open. Use the full custom flexible packaging RFQ checklist to organize the remaining project details.
