Flexible Packaging Specification Checklist

What belongs in a flexible packaging specification?

Record the product and intended conditions of use first, then define pouch format and dimensions, outside-to-inside material construction, features, artwork and print controls, test methods and conditions, acceptance criteria, sample plan, destination market and approval revision. Mark unknowns explicitly so they become review actions rather than hidden assumptions.

Keep a commercial estimate separate from the technical specification. Quantity can influence print and converting routes, but it does not prove material suitability, shelf life, seal performance or regulatory status.

Define the product and its risks
Record format, size and filling inputs
Document approval requirements
Revision, open items and approval owners

Define product risks and intended shelf-life conditions

Describe the product form, composition factors relevant to packaging, fill state and the ways quality could be lost. Oxygen, moisture, light, aroma, grease, acidity, puncture and seal contamination are separate failure questions and may require different evidence.

State the target shelf life together with storage and distribution conditions and the party responsible for validating it. A laminate abbreviation or barrier adjective cannot establish shelf life without appropriate product, package and process evidence.

Product identity and representative condition
Quality risks and expected failure modes
Target shelf life, storage and distribution
Validation owner and decision evidence

Record size, filling and sealing as one process

State flat width, height and gusset with drawing references and tolerances, plus target fill, density or volume behavior, headspace and orientation. Then describe whether filling is manual or automated and how the pouch is supported, closed and finally sealed.

Heat-seal temperature alone is not a process window. Where relevant, record temperature, dwell time, pressure, seal-area cleanliness, equipment reference and the filled-pack checks used to qualify the settings.

Drawing-controlled dimensions and tolerances
Target fill and product volume behavior
Filling equipment and sequence
Seal settings, cleanliness and line evidence

Specify the full material and component direction

Write the laminate outside to inside and identify film grades, thicknesses, coatings, inks, adhesives and sealant references where the project requires them. Separate material construction from appearance language and from functional features such as zipper, valve, window or notch.

For U.S. food-contact review, FDA explains that regulatory status depends on the individual substances, manufacturer where applicable, intended food type and conditions of use. A generic “FDA approved” statement is not a complete component record. Other destination markets require their own controlled review.

Outside-to-inside layer sequence
Grade, thickness, ink, adhesive and sealant references
Feature supplier or component references
Food type, conditions of use and destination-market evidence

Translate risks into tests and acceptance criteria

Choose film, converted-pouch and filled-pack checks from the identified failure risks. Each result must stay attached to the sample, method or agreed procedure, conditions, units, date and acceptance decision; do not compare bare values produced under different conditions.

Separate properties such as thickness, OTR and WVTR from seal, leak, feature-position and filled-pack behavior. The buyer and supplier should agree the relevant sample plan and limits before using a result as approval evidence.

Risk-to-test rationale
Method, revision and test conditions
Sample, result, units and acceptance limit
Film, empty-pouch and filled-pack evidence levels

Control artwork, commercial inputs and revisions

Record dieline and artwork status, designs or SKUs, color reference, print route if known and estimated quantity for commercial review. Keep unresolved commercial terms visibly open and do not insert an unsupported MOQ, price or lead time into the technical page.

Close the specification with document identity, revision, open items, approvers and decision date. A product, market, structure, dimension, feature, artwork or process change should trigger an impact review and defined revalidation rather than silently replacing the approved file.

Field map

Build a revision-controlled pouch specification record.

The checklist below defines fields and evidence, not StandPouchy target values. Buyer and supplier must enter project-specific requirements and agree which tests, limits and regulatory records apply to the intended product and destination market.

Specification field	What to record	Why it belongs	Evidence or decision owner
Packed product	Product name, physical form, representative condition and relevant composition factors	Anchors every material and test decision to the actual contents	Buyer product owner and named sample
Intended use	Food type or other application, contact type, fill state, temperature and duration	Regulatory and compatibility evidence is use-specific	Buyer regulatory input and applicable component records
Shelf-life brief	Target duration, storage, distribution and quality endpoints	Defines what the package validation must investigate	Buyer-defined target and validation plan
Failure risks	Oxygen, moisture, light, aroma, grease, puncture, compatibility and seal-contamination risks	Prevents appearance from driving the technical structure alone	Documented risk review
Pouch geometry	Format, orientation, width, height, gusset, tolerances and drawing revision	Controls forming, filling, artwork and packout interfaces	Approved dieline and size trial
Fill and headspace	Target fill, permitted variation, density or volume behavior and headspace	Connects geometry to representative product behavior	Filled-pouch review
Filling and sealing	Equipment, sequence, product state, temperature, dwell, pressure and cleanliness controls where applicable	Defines the process used to create the final package	Line or representative-process qualification
Laminate construction	Outside-to-inside layers, grades or supplier references and layer or total thicknesses	Identifies the actual material direction beyond a trade name	Controlled material specification
Print and conversion inputs	Ink, adhesive, coating, curing and converting details required by the project	These components and processes can affect use suitability and output	Supplier records and applicable review
Functional features	Zipper, notch, window, valve or hang hole references, positions and tolerances	Keeps components separate from material and appearance decisions	Feature drawing and functional review
Artwork and color	Dieline revision, artwork files, SKU count, color references and proof route	Controls what is printed and how it is approved	Approved proof and release record
Test plan	Risk-linked methods, conditions, units, sample plan and acceptance criteria	Makes results comparable and decisions auditable	Buyer-supplier agreement before testing
Regulatory evidence	Destination market, component identity, manufacturer where relevant and intended-use limitations	Avoids treating a generic statement as whole-package authorization	Responsible regulatory reviewer
Packing and distribution	Case arrangement, handling route and agreed representative checks	Connects the filled pouch to downstream use	Packout and distribution review
Commercial inputs	Estimated quantity, design count and unresolved quote assumptions	Supports quoting without turning estimates into technical claims	Buyer and supplier commercial review
Change and approval	Document ID, revision, open items, impact assessment, approvers and date	Prevents obsolete specifications from controlling production	Controlled approval and retained evidence

Method references

Verify the controlled method before testing.

FDA ties U.S. food-contact review to substance identity, applicable authorization, manufacturer where relevant and intended conditions of use. ASTM lists separate methods for barrier, seal and package-integrity questions. These sources do not approve a StandPouchy construction or supply project limits; use the current controlled requirements for the destination market.
