Avery A4 Double sided Laminating pouches are the ideal way to protect signs, photos and documents from the wear and tear of daily classroom use. They can be used to form long term displays of your signs, photos and documents in your school. Simply write or print your document, then slip inside the laminated film pocket & seal following the easy to use instructions. Documents are instantly laminated on both sides giving them protection from the day to day school life. No need to use a hot laminating machine in the classroom as these are self adhesive, only requiring a light pressure to seal the document permanently.
