All Round Savings
Recent developments mean that building products, cements and fine minerals, can be packed automatically into low cost plastic bags.
The cost of purchasing and operating a Form-Fill-Seal (FFS) bagging machine is now far lower than an automatic bagging line for pre-made bags.
Automatic and Dust Free
Form-Fill-Seal offers total automation, with no need to have an operator in attendance. FFS is dust free (now days a serious consideration when packing fine, powders) and very compact. Users also find that bags made on the FFS costs half as much as paper valve sacks.
Unique Technology
The special powder de-aeration and air evacuation systems combined with a range of plastic films from Rosenlew provide a water and dust proof package which extends the shelf life of building product from 2 to 9 months (or significantly longer).
The unique filling technique also makes sure that statically charged powder never comes into contact with the area of the plastic film which will be welded together.
Low Cost
Apart from costing 65% less than a fully automatic valve sack filling station with auto sack placer and ultrasonic valve sealing system, Form-Fill-Seal is more compact, dust free and accurate.
Simple Operation
The FFS machine un-winds plastic film from a flat roll and forms it into a tube which is then made into a bag before being filled with the de-aerated powder, while the top of the bag is being sealed, the bottom of the next bag is being made.
Flexible Automation
By changing the bag forming tube, FFS machine can also pack 5kg, 10kg, 12.5kg and 20kg bags - the small 5 and 10kg bags can also be made with handles and/ or a block bottom so that they stand up on the shelf for better 'point of sale' display in DIY stores.
Versatile and Fast
The new range of Form-Fill-Seal machines from Webster Griffin can pack mortar mixes, renders, screeds, fine ground minerals into 25kg bags at the rate of 6-8 bags per minute and aggregates at 20 bags per minute.
