Polyvinyl alcohol (PVOH) films exhibit several key properties that make them suitable for various applications:

  1. Barrier Properties: PVOH films have excellent barrier properties against gases, including oxygen and aroma compounds, as well as oils and greases,
  2. Water Solubility: PVOH films are highly soluble in water, which enables them to dissolve and disintegrate when exposed to water or moisture,
  3. Transparency: PVOH films offer good optical clarity, allowing for high visibility of packaged products,
  4. Mechanical Strenght: PVOH films exhibit high tensile strength and puncture resistance,
  5. Biodegradability: PVOH films are considered biodegradable under appropriate conditions. When exposed to certain environmental conditions, such as moisture and microorganisms, PVOH films can degrade over time, reducing their environmental impact compared to non-biodegradable plastics,
  6. Thermal Stability: PVOH films have good thermal stability, allowing them to maintain their integrity at moderate temperatures,
  7. Printable: PVOH films are printable and do not require no corona treatment,
  8. Anti-static: PVOH films are electrostatic resistant.
