Punched pocket

Punched pockets have several holes in the left edge, which allow them to be bound into a file folder or ring binder.

The clarity of the plastic will vary with the thickness of the pocket due to the semicrystalline nature of the polymers and Light scattering by particles.

One can see attached punched pockets, each containing a page with some information, in some banks, post offices and polyclinics.

These pockets allow numerous visitors to read the information closely without soiling, deterioration, or accidental removal.

Archivists and conservationists do not use punched pockets to preserve documents as they may create micro-climates, react with inks and stick to the paper.
