What does a bag filler do?
- Bag fillers fill bags. Seems obvious, but this primary role allows manufacturers to fill virtually any sized bag with almost anything.
- Bag fillers seal bags. Sealing is a hugely important feature of bag fillers. Not only does it keep the bag’s contents from deteriorating, but it also discourages tampering in-store. A sealed bag reassures the consumer that the quantity shown on the bag is the exact quantity inside.
- Bag fillers weigh bags. A 2kg bag of dog biscuits isn’t a 2kg bag of dog biscuits if it’s 1.8kg. Bagging machines weigh every bag to ensure precise filling before the bag is sealed. While good news for consumers seeking honesty in packaging, it also safeguards manufacturers against over-packing.
What are the types of bag filling machine?
- Small weight bag fillers mostly use open-mouth bags under 4.5kg and can even fill bags weighing a mere 28g.
- Bulk bag fillers are at the other end of the bagging scale and can fill super-sacks weighing as much as 1,800kg.
- Valve bag fillers fill 2kg to 55kg bags through a valve at the top of the bag greatly reducing spillage.
- Open mouth bag fillers also operate in the 2-55kg range but with an open mouth feeder.
What does a fully-automated bag filling system contain?
Quite a lot! In fact, a fully-automatic bagging system can pretty much take human involvement out of the equation by including all or most of the following;
- Bag placer
- Bag former
- Bag filler
- Check weigh conveyor
- Transfer conveyor
- Bag flattening conveyor
- Bag transport conveyor
- Bag closer
- Bag palletiser
- Bag positioner
What does a form-fill-seal bag filler system do?
Pretty much everything except driving the bag to its end destination. A full automated form-fill-seal system forms/opens a bag, fills it with the product and then seals it ready for delivery.
What must be considered when choosing bag fillers?
Plenty. The range of bag fillers available makes narrowing down the ideal machine quite overwhelming. However, if you go to your preferred supplier with answers to the following questions, they will be able to match the appropriate system to your current and future needs.
- What’s your budget?
- What products do you want to bag?
- How small are the bags – small, medium, large or super sacks?
- What weight range are the bags – as light as 28 grams or as heavy as 1,800kg?
- What are current and projected production levels?
- Does current productivity call for a modest system part-manual, part automated?
- Does current production call for full automation?
How much does a bag filler cost?
Bag fillers do tend to be expensive, but how expensive depends on how your bag-filling system is put together and the components within. Once you nut out the ideal bagging scenario with a supplier, they’ll give you a firm quote.
What are common problems with bag filling machines?
- Bag fillers aren’t cheap. In fact, they can be a bit on the pricey side. That’s why it’s important to accurately map out future bagging requirements before making a bag filler purchase. Will the bag filler pay for itself in time? Or is a less expensive machine going to make better financial sense?
- Bag fillers are high maintenance. This is largely because the maintenance of a bagging machine requires proper technicians from the machine supplier to carry out most if not all scheduled maintenance.
- Bag fillers use a lot of electricity. Self-explanatory, but it’s a cost that needs to be factored into the bagging process
- Bag fillers need bagging experts. Joe Warehouse-Junior can’t operate a bagging machine and wouldn’t know where to start if he tried. No, unfortunately, bagging machine operators are trained specialists with the technical know-how to operate what is a very complicated piece of equipment. Of course, such specialists don’t come cheap, but they will be able to do some of the machine maintenance, potentially saving a few expensive visits from the supplier techs.
What training or certifications do I need to operate bag fillers?
Bag fillers are specialised industrial machines. They should only be operated by employees with full training provided by the machine supplier and equally thorough training in all aspects of workplace health and safety.
