## Questions & Answers

**Q: will air still pass through it?**
A: If you stretch the film as you “wrap” your specimen cryovial, it will form a protective barrier against spills and will not allow air to penetrate.

**Q: Is this tape perferated?**
A: This tape is waxy and stretchy. It has no holes but is permeable to air. It is used to cover burn injuries but grafters  like it because it keeps moisture out but lets air in.

**Q: When you don’t need it any longer can it be easily removed from an object ?**
A: I use it for grafting plants. It can't be reused after sealing it for a long period.

**Q: I don't want the end result to look like I used a square sheet. Can I sckoosh this up in my hands then apply it manually?**
A: Parafilm is a flexible film.  You can stretch it into a number of shapes to meet your application. 
If you roll it up into a ball then it will be difficult to undo.

### ⭐⭐⭐⭐⭐ Great product

Works great 😁

### ⭐⭐⭐⭐⭐ Parafilm is 'da bomb
*by T***T on March 9, 2013*

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.
