Treating a material data-sheet value as finished-package performance
Packaging expertise
Barrier & Shelf Life
Barrier should begin with what can change the product: oxygen, moisture, light, aroma, grease, chemicals or loss of volatiles. The package, seals, closures and distribution environment all contribute to real-world performance.
PROJECT FOCUSBegin with what can change the product.
What the specification must resolve
What to confirm before production.
Oxygen, moisture, light, aroma, grease, chemicals and loss of volatiles are different failure paths. Set the barrier target from product sensitivity, package geometry, seals and closures, distribution and the shelf-life goal.
Key considerations
- OTR and MVTR targets
- Light and aroma protection
- Seal and closure contribution
- Testing under relevant conditions
Common applications
- Dry powders
- Coffee
- Snacks
- Sensitive formulations
Where projects go off track
Confirm these details early.
Requesting the highest barrier without a product-based target
Ignoring seals, closures, flexing and storage conditions
01Define the evidence and failure risk
02Separate product, material and process variables
03Test, document and approve the decision
A common question
Do OTR and MVTR values predict shelf life by themselves?
No. They describe transmission under defined test conditions. Product sensitivity, package area, seals, closures, headspace and real distribution conditions are also required for shelf-life work.
Experience Behind Packaging HQ
See the thinking applied in production.
These projects were personally led by Packaging HQ’s founder before Packaging HQ was established. They show how the same practical approach works under real production conditions.
