Parafilm M All Purpose Laboratory Film, 2 Inch Width x 250 Foot Roll Length, Semi-Transparent, Moisture Proof, Water Resistant, Non-Toxic, 200% Stretch Ability

Great stuff for sealing tops of bottles for shipping.

I'm a recovering biologist and the one thing I missed from the lab was this amazing product -- I always thought it would have been perfect for the kitchen -- and it is! It is great for covering containers without lids, creating a waterproof airtight seal (awesome!). Use it on the top of bottles of anything carbonated to keep the fizziness in (yay!) Use it on the side of non-watertight lids/caps to make them watertight (woohoo!). If you haven't used this stuff before, there will be a little bit of a learning curve to get the hang of judging how much you need to cut off, how to anchor one end, pulling it around the container and attaching the Parafilm to itself on the other side; but once you have that down, this is a great product and yes, it is expensive but it goes a loo-o-o-o-ong way.

Great for cooking and leftovers, etc. Used this in laboratory and is also great at home in the kitchen

GREAT product for sealing all kinds of things! If you really don’t want a leak, this will do it MUCH better than teflon tape or other useless tape. Stretch it and make it tight - you’ll be happy!!

Picture shows bemis parafilm but it was amcor parafilm that was delivered. Amcor is notoriously poorer quality and fails to stretch as parafilm should.

This is an authentic quality product sold by an outstanding merchant. Product works well. A customer service issue was resolved promptly and more than satisfactory.

Quality parafilm with a stretch but maybe not as much as other companies 100% worth the price

Great value at this price and long lasting for anything you need. If you’re starting off and need some practice. This is perfect for you.
