Flexible Packaging Materials Library

The material choice in flexible packaging determines barrier performance, seal integrity, printability, recyclability, and cost. This library covers the most common substrates, resins, and additive technologies used across the industry, with practical guidance for packaging engineers and buyers.

Films & Resins

PET, PE, BOPP, nylon, EVOH, foil, and their packaging applications.

Barrier Films

Oxygen, moisture, and light barrier technologies for shelf life extension.

PET vs PE

Comparing polyester and polyethylene for film and pouch applications.

Coextrusion vs Lamination

When to coextrude vs laminate and the tradeoffs for each approach.

Sealant Layers

How heat-seal layers work and what determines seal strength.

Recyclable Packaging Materials

Mono-material structures and design-for-recycling principles.
