It is not suitable for fragile products that could break when product drops from the Linear Weigher to the Bagging Machine during this process. Packaging speeds between 6 - 20 packs per minute can be achieved depending on product, volume and weight. This Bagger is a Pouch Present/Fill/Seal Machine, and is designed to be used with premade pouches. It offers many benefits including savings in labour units, professional presentation and consistency of finished products. Zip Lock pouches are most commonly used with a choice of Stand Up (flat bottom) or Full Gusset (square side) pouches. A full weigh packaging solution encorporating a bulk Product Conveyor, Linear Weigher for portion weighing, Pouch Presenting/Filling/Sealing machine, Metal Detector, Automatic Check Weigher to ensure target weight acceptance, Rejection Conveyor that removes packages if they are out of tolerance or metal is present, Rotary Table collects packaged goods ready for packing into final boxes/outers. There are many models of pouch filling machines to choose from with some capable of processing pouches up to 300 mm wide by 400 mm tall. The pouching machine can be further tailored with options such as; gas insertion (to aid shelf life), bag shaker (to make product settle), support table (for heavy products), inkjet printing (date and batch printing) and air extraction (to remove air from pouch). An estimated height for this system is 3.2 - 3.5 metres and the layout configuration can be changed to suit the size and design of your room. If packing powders into pouches the Linear Weigher would be replaced by an Auger Filler. A B C D E F G H I Multihead, Vertical Form Fill Seal & Finished Inspection Line This weigh packaging line is ideally suited to products that flow smoothly via vibrating pans without generating dust, e.g. potato crisps, frozen foods, grated cheese, fresh produce, rice, dried pet food, dried pasta, cereals, nuts, hard confectionery and fastenings/hardware. It is not suitable for fragile products that could break during the packaging process. This type of system is generally used for high speed, low cost, disposable packaging as once the bag is opened it can not be closed. It offers many benefits including savings in labour and low packaging costs. Packaging speeds between 20 - 100 packs per minute can be achieved depending on product, volume and weight. Our Multihead Weighers range from 10 weigh heads to 24 weigh heads and offer high speed & accuracy. You can also use these for mixing ingredients to get a consistent blend in your package. A full weigh packaging solution encorporating a bulk Product Conveyor, Multihead Weigher on a Working Platform for portion weighing, Vertical Form Fill Seal Bagger (VFFS) that forms and seals a bag from rolled substrate, Metal Detector, automatic Check Weigher to ensure target weight acceptance, Rejection Conveyor that removes packages if they are out of tolerance or metal is present, Rotary Table collects packaged goods ready for packing into final boxes/outers. The VFFS Bagger is designed for fast operation, generating its own bag from rolled film. Film can be blank, printed in the machine, or final presentation printed. Forming tubes are required for each bag width and can include gussets to make flat bottom or box bags (folded corners). There are many VFFS models to choose from and the right model will be determined by product being packaged, bag size and speed output. VFFS Baggers can be further tailored with the addition of; gas insertion (to aid shelf life), support table (for heavy products), inkjet printing (date and batch printing) and bag deflation (to remove excess air from bag). An estimated height for this system is 4 - 5 metres and the layout configuration can be changed to suit the size and design of your room. If you are packaging powders, the Multihead Weigher would be replaced with an Auger Filler.
