BUYER GUIDE

EVOH Barrier Sheet Extrusion Line buying guide

Compare the line by finished product, material structure, working width, thickness tolerance and saleable output. This BENK guide helps engineering and purchasing teams prepare a clearer quotation request.

01

Shelf life drives the structure

Oxygen and moisture targets determine where the EVOH barrier sits, how thick it should be and which tie resins protect it. The lowest material cost is not always the lowest total cost if the structure cannot meet the required shelf life.

02

Separate control protects the barrier

EVOH needs its own temperature and residence-time window. Dedicated extruders, a low-stress feedblock and uniform die temperatures help protect barrier performance while keeping structural layers stable.

03

Recycled content needs a plan

A dedicated regrind layer, filtration strategy and tie-layer design can support recycled content without putting regrind in the barrier layer. BENK reviews the full layer stack before quoting the line.

What to compare before approving a line

  • Layer sequence and tie-resin selection matched to the package
  • Independent extruder control for EVOH and adhesive layers
  • Online gauge and layer-inspection options for barrier consistency
  • Corona treatment, winding and downstream handling for converting
  • Documented changeover and operator training for multi-layer production

Share the target product, material, width, thickness and output with BENK. The final configuration is confirmed with a material trial and a clearly defined acceptance point.

EVOH Barrier Sheet Extrusion Line questions buyers ask

Use these answers to prepare a more accurate material, layer and output brief for the quotation.

What is an EVOH barrier sheet extrusion line used for?
It produces multilayer sheet with an EVOH oxygen barrier for food, medical and cosmetic packaging where shelf life and aroma protection matter. The structural layers provide strength and formability while tie layers bond the barrier to them.
How many layers should the line have?
A 5-layer structure is common for many packaging formats, while 7 or 9 layers provide more freedom for regrind, color, surface and barrier placement. The final structure is based on shelf-life testing, resin cost and the thermoforming process.
Can the line run recycled material?
Yes, when the layer structure includes a suitable regrind layer and the filtration and tie-resin strategy are designed for it. Recycled content is kept away from the EVOH barrier layer.
What information is needed for a quotation?
Send the target shelf life, packaging application, resin structure, sheet width and thickness, output and whether the sheet will be roll-fed or cut into sheets. BENK will size the extruders, feedblock, die and downstream equipment.
