Multi-gas Barrier

Films coated and metallized for high oxygen and water vapour barrier.

OTR down to 0,1 cc/m2 24h | WVTR down to 0,5 g/m2 24h

Performance is guaranteed by the synergistic application of Coathink®, the water-based coating technology, and metallization on a series of base films: BOPP, LDPE, MDO-PE, OPA.

These highly protective products enable the eco-design of recyclable packaging by replacing aluminum foil.

  • Longer shelf-life: greater performance of barrier properties
  • No Alu-foil: barrier effect expressed in a thin coating
  • Thinner: allows lamination with a thinner film
  • More sustainable: enables switching to monomaterials
  • Chlorine-free: no contamination upon use and recycling
  • High aluminum adhesion
  • Excellent oxygen and moisture barrier
  • UV barrier
  • Excellent sealability
  • Food
  • Nutraceutics
  • Industrial
  • Other

Used on a wide range of packaging where a high barrier to oxygen and moisture is required (e.g.: biscuits, milk powder, freeze-dried food, dried fruit, coffee, dietary supplements, vacuum pouches).

Eco-friendly because…
these advanced functional solutions replace traditionally used aluminum foil and reduce the thickness and the number of layers.

Main applications.

Food:

dehydrated soups, baked goods, powdered milk, dried fruit

Nutraceutics:

dietary supplements, powdered ferments

Application case

High barrier MDO-PE film for recyclable mono-material packaging

  • 20 um thick MDO-PE coated and metallized by SAES Coated Films
  • OTR <<1 cc/m2 24h  |  WVTR <1 g/m2 24h
  • Easy tear
  • High print quality
  • Excellent processability
  • MDO-PE (Machine Direction Oriented PolyEthylene) film is suitable for replacing PET or PP layers in many multi-material flexible packaging structures, enabling their conversion to 100% PE recyclable structures.
  • The oxygen barrier is provided by Coathink®, the water-based coating technology developed by SAES. The coating is less than one micron thick, equivalent to just 1% of the total weight of the packaging.
  • The synergy between coating and metallization enables OTR  performance of less than 1 cc/m2 24h (23 °C, 0% RH)and WVTR  performance of less than 1 g/m2 24h (38 °C, 90% RH).

The film is also available in transparent version with oxygen barrier.
