How a Standup Bag Form Fill Seal Machine Works
A standup bag form fill seal machine allows companies to produce many types of pouches for their products. This hygienic machine can also be outfitted with accessories that will add to the functionality of the pouch such as zippers, tear notches and a rigid spout inserter.
The main function of this type of VFFS machine is to automatically form, fill, and seal bags from a roll of film. This allows the manufacturer to save time and money on materials by eliminating the need for premade bags. This is an excellent option for businesses that require a high volume of packaging but want to avoid the expensive cost of purchasing premade bags.
To begin the forming process, the machine takes the film from its roll and moves it into a tube called a forming tube. It then heats the film and creates a bottom seal by clamping across it and sealing it together. This is done either at a constant speed or at a variable speed depending on the manufacturer.
Once the bottom seal is complete, the product is added to the bag by being dispensed directly into the forming tube or through an automatic weighing system. This is then sealed with either a lap or fin seal. The lap seal simply overlaps the two outer edges of the film to create a flat seal while the fin seal actually folds the film into itself and forms a pouch shape.
A variety of finishes can be added to the final bag including a hole punch for retail hang holes, an inert gas supply (like nitrogen) for reducing crushing on delicate products and a zipper application for easy closure. If the product will be a liquid or gas, the bag can also be inflated with air for better shelf presence and protection from contamination.
Some products can cause problems for a bagging machine like powders that tend to float and cling to the film. This can result in poor quality seals and an unattractive appearance for the bag. To help prevent this, a deionizer is often used to reduce the static charge on the film or product. This is especially important for powders that are exposed to the moving belts of the forming machine or when passing over rollers. If you're looking to invest in a form fill seal bagging machine, it's a good idea to consult with the manufacturer to discuss options and pricing. This way you'll be sure to find the perfect machine for your business. This will ensure that your products are well protected and your company can be successful on the market. You'll also be able to focus more energy on other business needs. This will allow you to increase productivity and make more profit in the long run.
