Multi gas barrier

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 0,45 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 of films based on BOPP and LDPE
  • Food
  • Nutraceutics
  • Industrial
  • Other

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

SAES Coated Films

Designed for recycling because…these advance functional solutions replace aluminum foil and enable mono-material structures.

Main applications.

Application case

Ultra High barrier Alu-free coffee bags

  • Triplex MDO PE / Coated & Metallized MDO PE / LDPE
  • Special coating process specifically designed for coffee packaging
  • Packaging barriers: OTR < 0.1 cc/m2 24h | WVTR < 0,2 g/m2 24h
  • Proven machinability on packaging lines
  • Proven coffee shelf life: 2 years
  • Already on EU market
  • PPWR -ready
  • 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 0.2 cc/m2 24h (23 °C, 0% RH) and WVTR performance of less than 0.45 g/m2 24h (38 °C, 90% RH).
