Packaging Testing & Validation: Practical FMCG Guide

A practical testing journey typically includes:

Raw Material Approval
Verify that incoming packaging materials meet critical specifications such as dimensions, weight, thickness, strength, appearance, and other material-specific requirements.

Supplier Qualification
Evaluate whether the supplier can consistently manufacture packaging within the required specifications and quality standards—not just produce one acceptable sample.

Development Testing
Compare materials, designs, structures, and packaging concepts during development. At this stage, testing helps engineers optimise the package before specifications are frozen.

Pilot Trials
Test the proposed packaging on the intended filling and packing equipment. Check areas such as container handling, filling, capping or sealing, labelling, coding, and case packing.

Production Approval
Confirm that production-representative packaging manufactured under normal conditions consistently meets the approved requirements.

Shelf-Life Validation
Evaluate the complete package with the actual product over time. Look for changes such as leakage, stress cracking, swelling, delamination, loss of adhesion, corrosion, or deterioration in dispensing performance.

Transportation Validation
Evaluate whether the complete packed system can withstand the intended distribution environment, including handling, vibration, impact, stacking, and relevant environmental conditions.

Key Takeaway

Testing should evolve with the packaging project.

Material → Supplier → Development → Pilot Trial → Production → Shelf Life → Distribution

The objective is not to perform every test at every stage. It is to generate the right evidence at the right stage, so problems are identified early and the final packaging decision is supported by relevant data.

Get a practical overview of packaging testing and the different types of tests used during packaging development and validation.

In this lecture, you’ll understand how packaging tests can be grouped into physical, mechanical, barrier, seal-integrity, and appearance/performance tests. We’ll explore common evaluations such as dimensions, weight, compression, drop, burst, torque, OTR, WVTR, seal integrity, colour, print quality, gloss, and barcode readability.

By the end of the lecture, you’ll have a clear framework for understanding what different packaging tests evaluate and where they fit into a packaging-development programme.

Learn how physical testing provides the basic measurable characteristics of packaging materials and components and helps confirm consistency against approved specifications.

In this lecture, we’ll look at common physical checks such as dimensions, thickness or caliper, weight, GSM, wall-thickness distribution, moisture content, and other material-specific measurements.

You’ll understand how these seemingly simple measurements can reveal important issues related to material usage, dimensional variation, component fit, manufacturing consistency, and overall packaging performance.

By the end of the lecture, you’ll understand what physical tests tell us, why they matter, and how they support packaging material approval and quality control.

This lecture introduces a practical material-wise testing matrix, helping you understand how test requirements differ across paperboard, corrugated boxes, flexible packaging, rigid plastic containers, closures, pumps, tubes, labels, foils, and blisters.

By the end of the lecture, you’ll be able to use the matrix as a quick reference for selecting appropriate tests during packaging development, qualification, and validation projects.

Learn the key tests used to evaluate the quality, strength, and performance of paperboard and corrugated packaging.

This lecture covers practical tests such as GSM, thickness or caliper, moisture content, COBB, bending stiffness, Edge Crush Test (ECT), Ring Crush Test (RCT), Flat Crush Test (FCT), burst strength, and Box Compression Test (BCT).

You’ll understand what each test measures and how the results relate to real packaging concerns such as carton stiffness, flute damage, moisture sensitivity, stacking strength, case collapse, and distribution performance.

By the end of the lecture, you’ll be better equipped to select relevant paperboard and corrugated tests based on the packaging application and expected failure risks.

Learn the key tests used to evaluate the strength, sealing, barrier performance, and functional quality of flexible packaging materials and laminates.

This lecture covers practical tests such as film thickness and GSM, tensile strength and elongation in MD and TD, coefficient of friction (COF), laminate bond strength, seal strength, seal integrity, OTR, WVTR, and filled-pouch performance testing.

You’ll understand how these tests relate to common packaging problems such as film stretching, web breaks, poor machinability, delamination, weak seals, leakage, and loss of oxygen or moisture protection.

By the end of the lecture, you’ll be able to select relevant tests for films, laminates, pouches, and sachets based on their structure, application, and expected performance requirements.

Learn the key tests used to evaluate the quality, structural strength, integrity, and product compatibility of rigid plastic containers such as HDPE, PET, and PP bottles and jars.

This lecture covers practical tests including container weight, critical dimensions, wall-thickness distribution, top-load strength, filled-bottle drop testing, leak testing, visual inspection, and product compatibility or ESCR testing where applicable.

You’ll understand how these tests help identify common packaging issues such as uneven material distribution, bottle buckling, panel deformation, cracking, leakage, neck or sealing-surface defects, and formulation-related stress cracking.

By the end of the lecture, you’ll be able to select relevant tests for rigid plastic containers and relate laboratory results to real packaging performance during filling, storage, handling, and distribution.

Learn the key tests used to evaluate the sealing, dispensing, functional, and durability performance of closures, pumps, trigger sprayers, and tubes.

This lecture covers practical evaluations such as application and removal torque, closure fit and leak integrity, snap-fit or pull-off force, pump priming, output per stroke, actuation force, spray pattern, repeated-cycle performance, tube seal integrity, burst resistance, and repeated-squeeze performance.

You’ll understand how these tests help identify common packaging problems such as closure leakage, incorrect opening torque, loss of prime, inconsistent dispensing, difficult actuation, poor spray performance, tube leakage, and component failure during repeated use.

By the end of the lecture, you’ll understand why these components should be evaluated as part of the complete packaging system—container or tube + closure or dispenser + product formulation—rather than only as individual components.

Learn the key tests used to evaluate the application, adhesion, appearance, durability, and information quality of labels and printed packaging.

This lecture covers practical evaluations such as label dimensions and registration, peel adhesion, edge lifting, print adhesion, rub and abrasion resistance, colour consistency, gloss, barcode and QR-code readability, and performance under relevant storage conditions.

You’ll understand how these tests help identify common packaging problems such as label lifting, bubbling, wrinkling, print scuffing, colour variation, loss of legibility, poor registration, and barcode scanning failures.

By the end of the lecture, you’ll understand how to evaluate labels and printed packaging on the actual packaging substrate and under realistic handling and environmental conditions, helping ensure the finished pack remains attractive, identifiable, readable, and functional throughout its intended life.

Learn the key tests used to evaluate aluminium foils, blister materials, lidding structures, and other specialised high-barrier packaging systems.

This lecture covers practical evaluations such as foil thickness, coating or lacquer quality, pinhole inspection, blister cavity formation and corner thinning, seal strength, package or cavity integrity, and barrier testing such as WVTR and OTR where applicable.

You’ll understand how these tests help identify common packaging problems such as pinholes, cracking during forming, excessive material thinning, weak lidding seals, coating defects, loss of package integrity, and reduced moisture or oxygen protection.

By the end of the lecture, you’ll understand why high-barrier packaging should be evaluated as a complete converted system—forming web + lidding material + seal + product—rather than relying only on the properties of the individual raw materials.

Learn how to move from individual laboratory tests to real-world packaging performance validation.

In this lecture, you’ll explore practical examples showing how temperature, humidity, storage, product compatibility, handling, stacking, transportation, and repeated consumer use can expose packaging weaknesses that may not be visible during basic material testing.

You’ll learn how to connect real packaging failures with possible causes, identify the most relevant validation approach, and evaluate whether the complete packaging system continues to perform under its intended conditions.

The key principle is simple:

Don’t just test the material—validate the package under the conditions it is expected to experience.

Learn how packaging performance can change over time and under challenging storage or use conditions, even when the individual components initially meet their specifications.

This lecture explores practical validation approaches for product–package compatibility, shelf-life performance, environmental exposure, stress cracking, ageing, leakage, deformation, delamination, corrosion, and changes in dispensing or sealing performance.

Through practical examples, you’ll understand why packaging should be evaluated with the actual product and under representative storage conditions, and how observations at different stages can reveal potential long-term failures.

By the end of the lecture, you’ll understand how shelf-life, compatibility, and special validation testing help confirm that the complete packaging system remains safe, functional, stable, and fit for purpose throughout its intended life.

Learn how to convert packaging requirements and potential failure risks into a structured, practical test plan.

In this lecture, you’ll follow a step-by-step approach to define the complete packaging system, critical performance requirements, potential failure modes, relevant tests, sample conditions, test quantities, and acceptance criteria.

Using a practical FMCG packaging example, you’ll see how to connect:

Requirement → Risk → Failure Mode → Test → Acceptance Criteria → Result → Decision

By the end of the lecture, you’ll be able to create a focused packaging test plan that generates relevant evidence for development, validation, and final packaging approval—rather than simply performing a standard list of laboratory tests.

Learn how to move beyond a simple pass-or-fail result and turn packaging test data into a confident engineering decision.

In this lecture, you’ll learn how to review results together, identify patterns, investigate failures, understand deviations, and determine whether a problem is related to the material, package design, manufacturing process, or complete packaging system.

You’ll also see how test results are brought together into a final packaging validation record, including test conditions, acceptance criteria, actual results, observations, and approval status.

By the end of the lecture, you’ll understand how to use testing evidence to make an informed decision:

Approve → Investigate → Improve → Re-test → Final Approval

The goal is not simply to generate laboratory data—it is to generate enough relevant evidence to make a confident packaging decision.
