A format change is any adjustment you make between two products: a different film roll, a different forming die, a different bag size, or a different dosing recipe. Every change takes time and materials. If you change formats frequently, you\u2019ll easily recoup the cost of a quick changeover.<\/p>\n
On a vertical form, fill, and seal machine<\/a> Replace the film roll, the die if necessary, adjust the sieve settings, and change the dosing recipe. On a flow packer<\/a> In addition, there is the product data entry: chains and sizes for each product type.<\/p>\n A trained team can change out a VFFS in 10 to 30 minutes and a flow packer in 15 to 45 minutes. The first 20 to 50 bags after each change are waste, as explained in the guide on film consumption<\/a>. With three shifts per day, that amounts to well over a hundred bags and more than an hour of production time.<\/p>\n With only two tool changes per day, the tools hardly pay for themselves. With three or more tool changes per day, or when running short, consecutive runs, servo and spare tool sizes are the logical choice.<\/p>\n Q: How long does a format change take on a VFFS?<\/strong><\/p>\n Training takes 10 to 30 minutes, depending on the servo control and whether the mold changer needs to be switched. Without a recipe memory, that time increases.<\/p>\n Q: How much waste does a switch produce?<\/strong><\/p>\n The first 20 to 50 bags are waste: film that hasn't reached the right temperature yet and seals that aren't set properly.<\/p>\n Q: Can I schedule shifts in production?<\/strong><\/p>\n Yes: Plan the sizes from small to large based on film width and group products by film type; this will eliminate entire changeover steps.<\/p>\n film consumption<\/a> | vertical form, fill, and seal machine<\/a> | servo-controlled machines<\/a> | VFFS or flow packer<\/a><\/p>\nThe cost of a bill of exchange<\/h2>\n
