Define intended use and target market
Confirm product, shelf-life objective, barrier need, storage, target-market and applicable product-contact or migration requirements.
Finished pack before machine platform
Stick pack and sachet format review for multi-lane projects.
Define the finished stick pack or sachet first, then review film, sealing, opening, filling and downstream conditions. A pack image alone cannot establish machine compatibility or production performance.

01Stick and sachet comparison
Compare the finished pack on one decision basis.
Use target, geometry, seal structure, residue sensitivity and downstream handling to choose the route before forming hardware or lane pitch is discussed.
Review all columns before selecting the finished-pack route.
| Decision | Stick Pack | 3-Side Seal Sachet | 4-Side Seal Sachet |
|---|---|---|---|
| Use target | Narrow single-dose presentation | Three sealed edges with one formed edge | Four sealed edges and wider presentation area |
| Geometry and display | Slim profile with limited print width | Flat pouch with asymmetric edge structure | Flat pouch with balanced perimeter seals |
| Seal structure | Longitudinal seal plus end seals | One formed side plus three sealed sides | Four perimeter seals |
| Residue sensitivity | Narrow drop and seal path require product-specific review | Fill path and open edge need review | Seal perimeter and product spread need review |
| Downstream handling | Lane discharge, count and orientation | Pouch transfer and orientation | Wider pouch transfer, count and presentation |
02Finished pack geometry
Turn the pack target into measurable inputs.
Dimensions, seal edges, headspace, opening, cut and print repeat need an approved reference before the forming route can be reviewed.
- 01
Finished width and length
State dimensions and tolerances from a drawing or approved sample basis.
- 02
Seal edges and headspace
Mark longitudinal or perimeter seals, usable fill area and required headspace.
- 03
Opening and cut
Define tear notch, laser or mechanical cut request, corner and consumer opening target.
- 04
Print repeat and registration
Provide artwork repeat, eye-mark data, print orientation and acceptable position basis.
- 05
Finished sample or drawing
Use a representative sample, dimensioned drawing and intended product condition together.
03Film and laminate responsibility
Confirm the evidence owner before trial or quotation.
Film structure and suitability are not inferred from a pouch image. Valid supplier and buyer information establishes the material basis used for equipment review.
Provide current film evidence
Provide structure, thickness, sealing window, barrier, migration and product-contact records applicable to the proposed laminate.
Review machine-route impact
Review the provided film basis against forming, tracking, filling, sealing, cutting and finished-pack handling questions.
04Material and dosing summary
Keep the material route connected without duplicating it.
Product behavior changes filling, residue control and seal protection. Use the dedicated dosing and material pages for the full engineering route.

Review material route05Form, seal, cut, register and observe
Connect the finished pack to the process decisions.
Each visible feature becomes an engineering input. Testing can observe agreed conditions, but it does not replace shelf-life, migration or regulatory validation by the responsible parties.
- 01
Forming and film path
Roll width, tension, tracking and forming geometry follow the approved pack basis.
- 02
Sealing
Seal window, product carryover, pressure, dwell and contact conditions require project evidence.
- 03
Cutting and opening
Cut position, notch, corner and opening features must be reviewed with the finished pack.
- 04
Registration and appearance
Print repeat, eye marks, graphics position and visual acceptance need a written basis.
- 05
Sample observation
Agreed testing may observe film travel, filling, sealing and appearance under stated conditions.
06Downstream impact and route split
Choose the next action from the remaining uncertainty.
Finished-pack stability, orientation, count, inspection and secondary packaging can change the line boundary after the format is selected.
Format clear
Prepare Engineering RFQ
Use the finished dimensions, film basis, fill target and downstream boundary.
Prepare format RFQBehavior uncertain
Plan Sample Testing
Use representative product and film to review agreed forming, filling, sealing and appearance conditions.
Review sample routeLine scope complex
Define the complete-line boundary
Connect qualified packs to inspection, transfer, counting and the agreed factory handoff.
Review complete line07 / Buyer questions
Bring one finished-pack basis into engineering review.
Prepare dimensions, seals, opening, print repeat, film evidence, product condition, dose and downstream target before the platform is selected.
Can a finished pouch image confirm the machine route?
No. Dimensions, film structure, seal window, product behavior, opening, registration and downstream conditions still need review.
What can a sample review establish?
It can record agreed observations for film travel, filling, sealing and appearance under stated conditions; it does not replace shelf-life, migration or regulatory validation.
