PARAFILM? M Laboratory Film , MADE IN USA

Description:
Product Codes: PM996,

General Description
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 selfsealing, 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.
