Classically used to promote products, brands, events and services. A flyer can often be described as a flat 1 or 2 sided sheet containing information of an advertising nature whilst leaflets are often folded with more pages and carrying more information although essentially they serve the same purpose.
Flyers and leaflets are recyclable. The recycling process removes and separates any laminating film. 'Green' lamination film made from ultra fine paper fibres is a compostable product.
