Is FFS Bagging A Simpler, More Cost-Effective Alternative To Valve Sack Filling?
FFS Machines vs Valve Sack Filling Machines
In the past, manufacturers packaging high density, light or fine powdered products had to use a valve sack filling machine. While Form Fill Seal (FFS) packaging machines also existed at the time, early versions couldn’t package these kinds of products well. It meant that businesses were forced to choose between the two machines, forgoing the benefits FFS machines have to offer.
While this might have been true in the past, it no longer is. FFS packaging machines have evolved in leaps and bounds since their invention. Here’s how they currently measure up to valve sack filling machines, and why you should consider switching to one.
What Do Valve Sack Filling Machines Do?
Valve sack filling machines have long existed and were — and are — primarily used to package powder products like chemicals, pharmaceuticals, foods, minerals, fertilizers, animal feed and more.
Valve bags are usually made from one or more paper layers, although some are made from polyethylene (PE), which is a light but durable plastic, making it robust and better able to protect products against moisture. Both materials are designed to be easy to handle and palletize.
Most valve sack filling machines excel at filling products into bags quickly and with reduced waste. However, some struggle with removing air from the packaged products, risking the packages later bursting under pressure. They also struggle at preventing product dust from spreading, creating a potential health and safety hazard.
How Do FFS Packaging Machines Compare To Valve Sack Filling Machines?
FFS packaging machines offer aerated and fine particulate product manufacturers an efficient, affordable and safe way to package their products. A common concern when packaging powders is its potential harm to the people exposed to it. The finer the product is, the easier it is to inhale. FFS packaging machines dramatically reduce dust, making it a safer choice for employees.
Another advantage they offer is that they can remove excess air by densifying products and making their packaging more airtight. They’re also more stackable and stable during packing, transportation and storage.
Many FFS packaging machines also support important functions like weighing and palletizing. The process starts when the product is fed into the hopper or feeder. Once a bag is formed, the product is filtered and vacuumed to mechanically compact it. Following this, specific weights are dosed into each bag before the bag is sealed. The bags are then transported to a palletizing machine via a conveying system.
Using a FFS packaging machine can decrease the time you spend packaging products — streamlining the process and removing added steps. It means that you can package more products in less time, with reduced waste and fewer hands involved.
Choose The Right Packaging Machine Partner
Not all FFS packaging machines are equipped to handle powder products. It’s why it’s important to partner with a company that can customise a packaging system to the specific product you make. Webster Griffin can assist you in accomplishing this, so contact our team today to get started.
