Promotional bags
Market needs
Made of organic (cotton, flax…) or synthetic fibres, advertising bags have a variety of shapes and colours. They are generally printed flat, folded. Silk-screen printing is selected for its inks, which must be opaque, thus increasing the contrast with the colouring of the canvas; and also for the brightness of the printed colours and the ease of production.
