Parafilm M PM992 All Purpose Laboratory Film,Semi-Transparent

I bought this for masking model aircraft canopies. The roll will last me a long, long time I think. I know the trick is to stretch the parafilm out first. I have not mastered the technique, but it seems promising.

Buenos productos buenas marcas. Excelente compra te será util

El pedido llegó incompleto.

I was a little worried after seeing some reviews suggesting the parafilm was too old and that it would break too easily, when my parafilm arrived I immediately took it out for a test wrapping the diameter on one wide mouth 1qt jar lid. At first I thought I had received a bad batch as It was constantly breaking as I tried to wrap around with 2, 3, and even 4 squares! An important note is this is my first time dealing with parafilm so I decided to double check to see if it was user error and it totally was! What you need to do is hold one end to your surface and then pinch just a inch away and stretch out small sections at a time, youll get a feel for when its time to add a little more slack to stretch out. Using this method, with the same parafilm I was able to go around my jar lid not just once but twice with only 2 squares! Good product theres a reason its so popular!

Great product

I don’t know how I have survived this long without using Parafilm. If you are using Petri dishes, I highly recommend this stuff. It blocks contaminants, and allows for gas exchange. Easy to use, even when wearing thick gloves. It isn’t sticky like tape. But seals a Petri dish amazingly well. There is enough on the roll to seal well over 250 Petri dishes.

Kind of rediculas that this roll is 20+$ more then other retailers and on top of that the film is old! Very dissatisfied. To get safe coverage over my dishes i have to use 2x the amount of film to make up for the cracking and snaping. Look els where for your parafilm. Itll probably be cheaper too.
