When it comes to choosing a bulk packaging system, every business has its own unique needs. There are different types of bulk packaging systems available on the market, and each machine comes with its own uses and advantages.
Some focus more on outer packaging functions such as forming, cleaning, and sealing. Others focus more on the interior of the package through filling, wrapping, and creative packaging solutions. What you’ll need depends on the type of items you’ll be packaging and the type of packaging you’ll be using, as well as your budget.
Form, fill and seal machines (FFS)
These machines are commonly used for food packaging, although they can also be used for other items including liquids and solids. The FFS machine creates a bag from a flat roll of film, while simultaneously filling the bag with the product and sealing the bag once it’s full. The advantages of FFS machines are that they can operate at a high speed and they’re ideal for running the same product continuously.
The cost of the film is cheaper than purchasing pre-made bags, so you will save on operating costs. However, changing the film is time-consuming, and if the bag is dropped it will often break.
Vertical form, fill and seal machines (VFFS)
VFFS machines fill each bag before heat sealing it, labelling it with a time stamp, and auto cutting the bag. Most VFFS machines can operate at about one finished bag per second, so they are ideal for businesses with high output requirements.
They can be used for small individual packages (like sachets) or for larger bags, and they can package a wide variety of materials like seeds, powders, liquids. VFFS machines are suitable for bagging oats, hay, mulch, fertilisers and more.
Bale packaging machines
Bale packaging machines use hydraulic cylinders to compress products to a quarter of their original size. This allows you to store more products, maximise your available space, and save on packing and transportation costs. This type of bulk packaging system is normally used for cereals, rags, sawdust, humus, straw, hay and fodder.
Valve bag fillers
These machines are consistent, accurate, and simple to install and adjust. Valve bag fillers use a two-stage filling system. The majority of product is filled at maximum rate, and then just before the bag reaches its target, the machine reduces the fill rate to a dribble feed.
This way, the machine can stop filling more accurately when the bag reaches its target weight.
Valve bag fillers are relatively small machines, so they don’t take up a lot of floor space. They’re suitable for packaging dry materials, powders and granular products such as soil, mulch, minerals, grains or concrete mix.
Pre-made bags or open mouth baggers
These systems are extremely flexible. They are compatible with paper bags or woven bags, heat sealers, inner liners, stitched outer bags, fold overs and taped seals.
They offer various feeding methods including gravity feeding, auger feeding, and vibratory feeding, providing you with the ability to package unusual products.
You can add dust extraction systems or bag compression functions depending on your business needs. Poly woven bags are, on average, more robust than FFS bags, but your cost per bag will be higher. Open mouth baggers also tend to be slower than FFS systems.
