For startups, entrepreneurs and small businesses, learning more about how each piece of equipment works in any processing line is important. Not only will understanding how the bag filling machines operate help to make a choice, but it will also help you to compare different equipment options.
Bag fillers, which are also known as a vertical form, fill and seal machines of (VFFS), are used in all types of industries. While they are used in the bagging of food, pharmaceuticals and even beverages, they are also used in other types of production and packaging as well. Anytime you see bagged items with any product a VFFS has been used if they are sealed.
Types of Bags
There are several different types of bags and bagging requirements that can be offered through these bag filling machines. There are at least 5 different bag forms that can be used for both foods, liquids and other types of materials during the bagging process.
These include the pillow type of bag, typically used to add protection to the contents or to use a controlled atmosphere type of packaging for perishable items. The zippered bag is very popular and allows the end consumer to reseal the bag, keeping the contents fresh. Gusseted and stand-up bags are the other common options used in production.
Additionally, it is possible to use film to have the equipment generate four sealed bags. These are sometimes known as quad sealed bags, and the bag itself forms a pouch around the contents, making these, and the stand-up bags, easy to stock on shelves and pack in cases without a lot of wasted space.
Single or Dual Web
Single web types of bag filling machines use one roll of material while dual web uses two. The dual web option is required for pouch types of bags and allows a smooth, simple process that creates the bottom of the pouch, measures the product to the desired level, fills the bag, and then creates the top closure of the pouch (four-sealed or stand-up) bag.
Of course, having precision weighing on the bag filling machines is going to be critical. Too much or too little product in the final bagged item is going to result in additional waste on the line and challenges both in brand reputation as well as in cost management and control of production.
It is a wise decision to compare all equipment you are considering with at least one or two other brands and manufacturers. Choose companies that have brand recognition, a solid reputation, and that provide top customer service and support.
