What is a Flap seal?

A flap seal is a sealing method used to close the opening of bags, envelopes, and other packages. This type of seal involves folding a flap (a folded section) at the top or side of the bag and sealing it with a sticky material, ensuring that the package is tightly closed. Flap seals are often designed to be easily opened and resealed, making them popular in food, pharmaceutical, and electronic packaging. They provide a high level of sealing integrity, helping to preserve the contents and protect them from external contamination.
