For these products, the vertical form, fill, and seal machine is the standard platform: up to 80 bags per minute with \u00b11% dosing accuracy, depending on the product and film.<\/p>\n<h2>The Structure of the Line<\/h2>\n<p>The basis is the <a href=\"https:\/\/lintyco.nl\/en\/verticale-vorm-vul-en-sluitmachine\/\">vertical form, fill, and seal machine<\/a>: film roll, forming shoulder, bottom and top seals. Above the machine, a <a href=\"https:\/\/lintyco.nl\/en\/multihead-weger\/\">multi-head weigher<\/a> accurately fill the bag to the specified product weight. For fine granules that are dusty or sticky, a screw feeder is the alternative.<\/p>\n<h2>Step-by-Step Guide to the Selection Process<\/h2>\n<ol>\n<li>Test the product: flow, particle size, dust formation, susceptibility to breakage.<\/li>\n<li>Set the dosing range, from the smallest to the largest bag weight.<\/li>\n<li>Select the bag size and type: pillow bag, stand-up bag, or block-bottom bag.<\/li>\n<li>Record output in bags per minute, not in hourly rates on paper.<\/li>\n<li>Select the film based on its single-material composition and barrier requirements.<\/li>\n<\/ol>\n<figure class=\"wp-block-table\">\n<table class=\"has-fixed-layout\">\n<thead>\n<tr>\n<th>Product<\/th>\n<th>What to Look For<\/th>\n<th>Dosing device<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Sugar and Salt<\/td>\n<td>Fine particles, dust formation<\/td>\n<td>Multihead weigher with cover, or screw feeder<\/td>\n<\/tr>\n<tr>\n<td>Rice and Grains<\/td>\n<td>Prone to breakage<\/td>\n<td>Multihead weigher with a low drop height and a gentle infeed<\/td>\n<\/tr>\n<tr>\n<td>Animal Feed Pellets<\/td>\n<td>Dust and Grease<\/td>\n<td>Multihead weigher, 304 stainless steel product contact<\/td>\n<\/tr>\n<tr>\n<td>Fertilizer pellets<\/td>\n<td>Corrosive<\/td>\n<td>Stainless steel 316 version and corrosion-resistant seal<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<\/figure>\n<h2>Plastic Film and Sustainability<\/h2>\n<p>Granules require a dust-tight seal; a 50- to 80-\u00b5m PE monolaminate is sufficient for this purpose, as it is recyclable as a single material. When requesting quotes, ask for the film consumption per 1,000 bags\u2014this difference between machines will persist as long as the line is running.<\/p>\n<h2>What We've Learned from Experience<\/h2>\n<ul>\n<li>Dust in the seal seam is the classic problem with sugar and salt: the seam doesn't seal, and the bag leaks. Vacuuming at the filling station and a field dosing system solve the problem.<\/li>\n<li>Rice and grains break during the fall; a low drop height and a gentle feed rate keep breakage to a minimum.<\/li>\n<li>Hygroscopic granules clump when exposed to moisture; store and transport them in a sealed container to a location just above the machine.<\/li>\n<\/ul>\n<h2>When a VFFS for granules isn't suitable<\/h2>\n<ul>\n<li>Sticky or highly hygroscopic product: the dosing chute becomes clogged and dosing stops.<\/li>\n<li>Is the <a href=\"https:\/\/lintyco.nl\/en\/doy-pouch\/\">doypack<\/a> If that's your main selling point, then choose a <a href=\"https:\/\/lintyco.nl\/en\/machine-voor-het-vullen-van-voorgemaakte-zakken\/\">packaging machine for preformed bags<\/a>.<\/li>\n<li>Bags weighing approximately 10 kg or more require a heavier-duty frame; discuss the dosing weight with the supplier in advance.<\/li>\n<\/ul>\n<h2>Frequently Asked Questions<\/h2>\n<p><strong>Q: Which film should I choose for granules?<\/strong><\/p>\n<p>PE monolaminate for dry granules, or a barrier-lined film if the product loses moisture or odor. The bottom seal must be dustproof.<\/p>\n<p><strong>Q: How do I prevent dust from getting into the seal?<\/strong><\/p>\n<p>With extraction at the filling station, field dosing, and a film selection that matches the particle. Check the first bags after each film change.<\/p>\n<p><strong>Q: Can a single machine process both granules and powder?<\/strong><\/p>\n<p>Yes, by switching the dosing equipment: a multihead weigher for granules and a screw feeder for powder.
