Use Iron on Low Heat to Unstick Envelopes

People have been using iron heat to unstick envelopes for a long time. Few follow the accurate steps, and few make mistakes which should be avoidable.

This way is effective for both thick and thin paper. But when the paper has something glittery or glossy, this way is not appropriate.

Now take the iron and heat it low, don’t use high heat.

Then, take the envelope, place the damp cloth on it, and gently place the iron on the damp cloth.

Leave it for 3-4 seconds. Now, look carefully if the gum is loosen or not. If the gum is still adhesive, repeat the process for more 3-4 seconds.

After processing, use a knife to separate the envelope’s head.

Thin Envelopes

When the envelope is of thin material, you can directly place the iron on it. Make sure the iron is not too warm, low heat will work effectively.

Place the iron on the envelope for 2-3 seconds, the gum will get loosen. Later, Using a knife, complete your unsticking.

Use Boiled Water to Unstick Envelopes

Here you’ll need to steam the envelope with boiled water. If your envelope’s paper is too thin, don’t use this because water vapor can make the envelope bad.

At first, take a kettle or water pot. Wait until water starts to boil extremely.

Then start the machine and blow air in the head of the envelopes. Observe carefully if the glue is loosing or not.

Place your stuck envelope in the microwave. Long with the envelope, place a cup of mug too. This is to keep the moisture of the paper.

Then start the machine and leave it for 20 seconds.

Your envelope will easily get loosened by then, and you can easily make it separate.
