Description

PARAFILM Roll PM-996 4 Inch x 125 FT. (1 Roll), USA

A flexible sealing film comprising a proprietary blend of waxes and polyolefins on a paper release liner

Features

  • Parafilm “M” is highly insensitive to water, moisture loss, and moisture absorption, yet is permeable to oxygen and carbon dioxide.
  • Parafilm “M” stretches more than 350% of its original length and is self-sealing, allowing it to cling around irregular shapes and surfaces.
  • These unique properties make it ideal for protecting the contents of test tubes, flasks, beakers, and Petri dishes as well as an overwrap to further secure stoppers, lids, and caps.
