Clear Plastic Lab Wrap is designed specifically for the lab. It has “low tangle” properties to insure that it doesn’t ball up when handled. It also has “high cling” properties to enable wrapping a beaker, flask, or petri dish with an extraordinary tight seal that stays in place. The clarity of the film allows you to see through it. The distinctive proprietary formulation yields ultra-clean film to ensure sample purity and eliminate contamination. It is made of 100% polyethylene. The carton has a metal tear- off bar for ease in achieving the exact size needed. The carton also has unique “flaps” which prevents the roll from leaving the box. Plastic wrap size is 12 inches wide by 100 feet long.
