My original order of the parafilm didn’t work due to defects of dryness and breaking into fragments easily. I contacted the seller and the seller went above and beyond by sending a full refund and a new roll free of charge. I appreciate the seller’s professionalism and outstanding customer service!

5.0 out of 5 stars Unbelievably stretchy
Reviewed in the United States on June 6, 2024
Using the paratape for keeping bacteria out of test dishes for mushroom cultivation. Apparently it worked just as it should because I had no bacterial growth in 7 out of 7 agar plates so I don't have to isolate any mycelium, it's all looking good. It's mode of adherence is the stretch (kind of like saran wrap) and wow! Does it stretch. It wraps, clings and keeps the agar dishes closed while letting air escape in the mycelium growth process. This whole process is new to me so having a quality product to work with is really nice.

Despite the product itself seems to be of the right count and okay at first glance, the package arrived opened from two sides.

5.0 out of 5 stars Perfect for bottles

Bought this to seal my tequila bottles for long term storage. Takes some time getting used to it, how much to stretch it out but well worth the price and investment.

5.0 out of 5 stars Perfect for sealing perfume bottles and vials
Reviewed in the United States on July 26, 2022
I was familiar with Parafilm from my student days in Chemistry labs. I started hearing from people that Parafilm had uses outside of the lab as well. Folks are using it to seal perfume bottles, decant, and travel sprays to prevent or reduce perfume evaporation. There is a bit of a learning curve to using this stuff. It is stretchy, but if you pull too much, it will break. That's why I gave it 4 stars, even though the roll I received was in great shape. Very happy to have it!
