<p>Disclosed is a thermoplastic flexible film suitable for wrapping static sensitive devices such as electronic circuit boards. The film is made of an inherently hydrophilic polyether block amide copolymer in blend with a compatible polymer. Compatible polymers typically are amide polymers or are acid copolymers, such as the nylons or ionomers. The film has a degree of hydrophilicity suitable for packaging static sensitive devices, yet the film is antistatic without requiring the addition of an antistatic agent.</p> |
