EVOH Film – When the Barrier Really Matters
If you are packaging a product that is sensitive to oxygen, and shelf life and freshness are critical, EVOH film is one of the most commonly chosen barrier solutions. EVOH (ethylene-vinyl alcohol copolymer) is used in packaging when you want to limit oxygen penetration, and thereby slow down oxidation and loss of quality. In practice, a well-chosen EVOH structure translates into more stable product parameters over time and a lower risk of complaints.
As a manufacturer of printed film packaging, we use EVOH in multi-layer structures where it is justified – that is, when the oxygen barrier makes a real difference and is not just a buzzword in a specification.
What EVOH Film Delivers in Packaging
Simply put, EVOH film is designed to provide a high oxygen barrier. This matters for products that lose taste, aroma, or properties when exposed to oxygen. In many applications, EVOH helps extend shelf life and maintain consistent quality for the end customer from batch to batch.
It is important to remember, however, that EVOH is usually one layer within a packaging structure. The mere presence of EVOH is not enough if the other layers are not well suited to sealing, durability, and storage conditions.
EVOH Packaging – Where It Works Best
You will encounter EVOH structures particularly where oxygen protection and maintaining quality over time are important. This most commonly applies to food products, pet food, bulk blends with an intense aroma, and selected technical products. If a product is to be stored for a long time, transported, or sold through multiple channels, the oxygen barrier can be a critical parameter.
In practice, EVOH is often combined with layers that handle sealing and mechanical strength. This means the packaging not only protects but also performs reliably on the production line.
EVOH Film and Automatic Packaging – What to Watch Out For
If you are packaging on an automatic machine, repeatability matters. The packaging must run stably, and the seal must be predictable within your process window. As a barrier layer, EVOH must not impair line performance, which is why we design the structure to maintain good sealing properties and stable parameters across successive batches.
If you are introducing a new material, samples and a trial run on your machine are the simplest way to avoid losses on a large print run.
When EVOH Film Makes Sense
EVOH film makes sense when you need a genuine oxygen barrier and want to better protect your product over time. The most important thing, however, is that EVOH forms part of a well-chosen structure – matched to the sealing requirements, mechanical durability, and storage conditions. If you want to implement EVOH packaging for your product, send us the format, quantities, and information about your packaging method – we will prepare a proposal and a quote.

FAQ
EVOH is a barrier layer used in packaging where high protection against oxygen transmission is required. It helps preserve product freshness and quality over time.
EVOH is most commonly used as one of the layers in a multilayer structure. The other layers provide functions such as sealability and mechanical strength.
EVOH packaging is most commonly used for oxygen-sensitive products where shelf life and aroma preservation are important, such as food products, pet food and selected technical products.
Yes, provided that the entire packaging structure is selected to suit your machine. Key factors include film handling, the sealing window and batch-to-batch consistency.
We need the format and dimensions, required quantity, type of product, storage conditions and packing method, whether manual or automated.
