Pouch Sample Approval Guide

How should I approve a flexible pouch sample?

First identify whether the item is a stock format reference, material swatch, digital or printed proof, machine trial, pre-production sample or production sample. Approve only the dimensions, construction, print, features or process conditions that the named sample genuinely represents.

Compare that sample with the same revisions of the specification, dieline and artwork intended for release. Record each result as accepted, rejected, open or not represented; a single “approved” message hides exceptions and cannot show what still needs filled-pack confirmation.

Review dimensions, print and features
Specification, dieline and artwork revisions
Item-level decision and reviewer

Check traceability before appearance

Label the sample with supplier or converter, material or job reference, lot where available, date and production route. Confirm whether it was handmade, digitally printed or produced through the intended converting route because those paths may not represent the same color, seals, registration or surface behavior.

Photographs are useful evidence of condition, but they do not replace the retained physical reference or measured result. Keep images tied to the sample ID, review date and observation.

Measure pouch construction and feature positions

Measure flat width, height, gusset and agreed seal or feature references using the controlled drawing convention. Note sample condition and measurement method so an empty flat measurement is not confused with a filled outside dimension.

Inspect zipper, notch, window, valve and hang-hole presence, side, alignment and observable function. Record results against project tolerances where they exist; do not invent a universal StandPouchy tolerance.

Seal geometry and visible condition
Closure and opening-feature positions
Window, valve and hang-hole registration

Review print, copy, barcode and surface finish

Compare copy and artwork with the released proof, including SKU, language, barcode data and required marks. Review color against the agreed physical or measured reference under the specified viewing conditions rather than relying on an uncontrolled screen or room light.

Inspect registration, small text, reverse copy, scuffing, blocking, gloss or matte consistency and unintended marks. Barcode appearance alone is insufficient; verify the printed and formed symbol through the applicable process.

Fill and seal with the intended product and process

An empty pouch cannot approve usable volume, fill access, seal contamination behavior, headspace, standing shape or closure access. Use a representative product and the intended filling sequence, then close and seal with recorded equipment and process settings.

Review observable seal condition and select any integrity or strength methods from the project risks. ASTM F88/F88M measures force for a defined seal specimen and failure mode; ASTM D3078 addresses gross leaks within its scope and notes that small leaks may not be detected. Neither supplies a universal pass value.

Review packing, handling and release status

Pack the filled pouches in the intended orientation and review contact points, carton fit and observable effects of representative handling. If a transport or distribution test is required, define the procedure, samples and acceptance criteria before treating it as approval evidence.

Close the record with accepted items, rejected items, deviations, open actions and disposition. Any change to product, size, material, feature, artwork or process requires an impact review and a new controlled revision; retain the approved reference according to the project record plan.

Field map

Use one record to separate sample evidence from open work.

The field map does not set universal tolerances, seal strength, leak limits, color difference or transport targets. Record project criteria before review and mark anything the sample cannot represent as open or not applicable.

Approval field	What to record	Decision question	Evidence retained
Sample identity	Sample ID, type, purpose, supplier, job or lot reference and date	Which physical item is being reviewed?	Labeled sample and receipt record
Representativeness	Handmade, proof, trial, pre-production or production route; included and omitted attributes	What can this sample validly approve?	Declared sample scope
Controlled references	Specification, dieline, artwork and color-reference revisions	Is the sample compared with the intended release files?	Linked controlled documents
Review plan	Reviewers, sample quantity, methods, conditions and project acceptance criteria	Were decisions defined before inspection?	Approved review plan
Flat dimensions	Width, height, gusset, reference points, method and results	Does geometry match the controlled drawing and tolerance?	Measurement record
Seal construction	Top, side and bottom seal geometry, alignment and visible condition	Does the converted pouch match the approved construction?	Measurements and inspection images
Closure and opening	Zipper, notch and opening location, alignment and observed operation	Can the intended user and filling route access the pouch as planned?	Feature check on named samples
Other features	Window, valve or hang-hole identity, side, coordinates and observable function	Are optional components present and correctly registered?	Drawing comparison and functional observation
Artwork and copy	SKU, language, required copy, barcode data, registration and legibility	Does the printed content match the released proof?	Annotated proof comparison
Color and finish	Reference, viewing condition, agreed method, results and surface observations	Does the sample meet the project color and finish decision?	Reference ID, readings where agreed and photographs
Filled-pouch setup	Representative product, fill, headspace, equipment, sequence and seal settings	Was the pouch assessed under the intended packing route?	Filled and sealed sample record
Filled-pack use	Standing, opening, reclosing, handling, distortion and seal-area observations	Does the pack geometry and feature use work with the actual product?	Recorded observations and named samples
Integrity evidence	Selected method, conditions, result, units, failure mode and acceptance criterion	Do the risk-based seal or leak checks meet the agreed limit?	Test report linked to sample ID
Packing and handling	Carton orientation, contact points and defined representative procedure	Does downstream packout reveal an issue?	Packout record and any test report
Disposition	Accepted, rejected, deviation, open action or not represented for every field	What is approved and what remains unresolved?	Item-level decision log
Release and retention	Decision, approvers, date, corrections, revision impact and retained-reference location	Can the release be reconstructed after a later change?	Controlled approval and retained sample record

Method references

Verify the controlled method before testing.

F88/F88M measures the force required to separate a defined seal specimen and records failure mode; it does not simulate every whole-package use. D3078 is limited to gross leaks in flexible packs with headspace gas and may not detect small leaks. GS1 barcode checks include data, quiet zones, contrast, construction, placement and packaging effects. Apply only the current methods relevant to the project.
