AI Overview
EVOH barrier film testing ensures high-performance packaging meets strict permeability and mechanical standards. Essential tests include measuring Oxygen Transmission Rate (OTR), Water Vapor Transmission Rate (WVTR), and gelbo flexing to evaluate flex-crack resistance. Specialized tools (e.g., Nireos TRICLOPS) identify EVOH layers. Key metrics include monitoring for high humidity which impacts barrier performance.
This video explains how permeation analyzers are used for testing the barrier properties of films:

Is EVOH a good oxygen barrier?
Ethylene vinyl alcohol (EVOH) is one of the best known flexible thermoplastic oxygen barrier materials in use today. It is especially important for refrigerated and shelf-stable foods where oxygen deteriorates the quality of packaged products and reduces their shelf life.

What is 5 layer EVOH barrier film?
EVOH based 5 Layer Films provide excellent barrier properties against the permeation of gases, superior to those of any other conventional polymer. The gas barrier prevents oxygen to easily penetrate the package and spoil the contents. An outstanding oxygen barrier will help food from spoilage and extend shelf life.

What is EVOH film used for?
The main characteristic of EVOH copolymers for packaging applications is their outstanding barrier to gases (oxygen, carbon dioxide, …) and organic vapors (food aroma). EVOH is applied in multilayer structures for bags, trays, cups, bottles, squeezable tubes or jars to protect oxygen-sensitive products.
