If you're hoping to seal an envelope with a quick blast in the freezer, you may be disappointed to learn that this method doesn't work. Freezing won't magically seal your envelope, and in fact, can actually make it more difficult to seal.
The reason why freezing an envelope doesn't work is because the cold temperature causes the glue to contract. This makes it harder for the glue to adhere to the envelope, and as a result, your envelope is less likely to seal properly.
So, if you're looking for a way to seal an envelope quickly, the freezer is not the answer. However, there are a few other methods you can try.
One way to seal an envelope is to use a moistened sponge. Simply run the sponge along the envelope's flap, and then press the flap down to seal. This method works because the moisture from the sponge helps to reactivate the glue, making it easier for the flap to adhere.
Another method is to use a hair straightener. Simply place the envelope between the two plates of the hair straightener and press down. Hold for a few seconds, and then release. This method works because the heat from the hair straightener helps to reactivate the glue, making it easier for the flap to adhere.
So, if you're looking for a way to seal an envelope quickly and easily, try one of these two methods.
