🧪 Seal your science with confidence — the lab’s invisible guardian!
The HS234526B Para Film M is a 4-inch wide, 125-foot long flexible sealing film designed for laboratory use. It offers a strong moisture barrier that clings tightly to glassware, preventing moisture loss and contamination. Odorless and semi-transparent, it stretches over 200% to fit irregular surfaces and resists many polar substances for up to 48 hours, making it an indispensable tool for healthcare, pharmaceutical, and research labs.

Parafilm is 'da bomb
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.

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

It REALLY does seal the deal!!
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!!

Total Dissapointment
Unfortunately, this film falls apart after just a few weeks. I used it for sealing tobacco tin lids, and even with only moderate stretching, it pulls apart as time goes on. I've heard a rumor that the tape has changed over time, but I can not confirm that. I just know this is worthless for the application it was recommended for, as it comes apart after a few weeks. Boo.

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

Long lasting
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.

Había comprado uno de la marca amcor y no me gustó porque venía muy marcado o señido con puntos la banda de parafilm y a la hora de estirar esas marcas o señidas provocaban el rompimiento, probé otro de la marca bemis y es muy bueno, se siente más grueso que este de marca amcor, y estira más parejo, es de mejor calidad y desempeño, por eso quise comprar de marca bemis, supuse que Amazon me enviaría de esta marca porque así se ve en las fotos del producto, pero no, me envío marca amcor la cuál me volvió a decepcionar, supondría yo que deberían estar estandarizados sus productos aunque sean diferentes marca, porque tienen una licencia para hacer parafilm, pero no es así, yo recomendaría más la marca bemis.

Il prodotto è ottimo, tuttavia il prodotto da me ricevuto è il PM-992 che è di altezza 50m e non 100cm come indicato nella descrizione Amazon, quindi esattamente la metà di quello atteso

Perfekt genau was ich wollte

Parafilm is synonymous with lab work, every lab I've been in has a roll of it somewhere (often coveted by that one researcher who's work is clearly more important than yours and believes you to be a lesser creature in the grand scheme of scientific discourse and therefore a resource like this is worth keeping away from you). This is that stuff, there are cheaper alternatives and buying them will likely create more problems than the money saved will solve. Buy this stuff, it does the thing lab workers expect it to. Non-sciencey people > Parafilm is like fancy cling film or cellophane, the big difference is the low chemical reactivity, the stretch and sealing properties mean you can cap a tube or flask with reasonable expectation of air/water tightness. And if you want, you can scrunch it up and block stuff with it. I use it sometimes to cover vinegar/oil flasks or to cap storage bottles I've lost the tops of in everyday life..... cause I sometimes do cool science stuff and fail at everyday life stuff (like remembering where caps are)
