FORM FILL SEAL PROCEDURE FOR PACKAGING ARTICLES IN BAG FILLED WITH AIR

摘要

The procedure for packaging articles comprises the steps of: providing a packaging sheet (2) having a longitudinal extension and two longitudinal edges (4); moving the packaging sheet (2) forward along a direction of forward movement (A) substantially parallel to the longitudinal extension; arranging a plurality of articles (3 ) on the packaging sheet (2) at a reciprocal distance (D) along the direction of forward movement (A); - moving the longitudinal edges (4) close to each other to form a substantially tubular section (10) of the packaging sheet (2) having an open extremity (11) and the articles (3) inside; blowing air in the substantially tubular section (10) through the open extremity (11); - sealing the longitudinal edges (4) together longitudinally; sealing transversally the substantially tubular section (10) downstream and upstream of each of the articles (3) to form a plurality of closed packages (22) containing the articles (3) and substantially swollen with air.
