When it comes to liquid filling – whether that’s dispensing from bulk containers into smaller vessels, working with viscous or aerated formulations, or managing the full process from blending through to despatch – Grotech Production has the experience and equipment to handle it.
With over 40 years in contract manufacturing and packaging across the general chemical, agriculture and horticulture sectors, we understand that no two liquid filling projects are quite the same. Here’s a good example of what that means in practice.
How did Grotech Production’s liquid filling services help textile makers in Sweden and China?
Silver is well-known for its biocidal properties for killing bacteria and viruses. Liquid silver matrix is used by textile makers in China and Sweden as a fabric protector. The silver matrix solution has been cleverly formulated so that it is suspended in a surfactant enabling it to become enmeshed in fabric. While the silver remains enmeshed – which is usually for quite a long time – it continues its biocidal effect.
The patented silver matrix formulation is supplied to us by our customer in bulk IBCs in 10 tonne batches. It is our brief to repack it, using our liquid filling machines to fill it into significantly smaller containers – either 1 litre, 5 litres or 20 litres in size.
The nature of the product is such that it occasionally has high levels of viscosity and aeration of the surfactant, which makes it tricky to fill into the smaller bottles. The liquid filling system we have at Grotech means we are more than capable of working with viscous liquids. We slow stir the compound to disperse any high viscosity layers while deaeration allows any froth to subside. Our liquid filling machinery does the rest, with filling nozzles ensuring a smooth fill into the bottles.
Grotech has a range of liquid mixing vessels including stainless steel, HDPE and polypropylene, plus filling machinery enabling us to vary our manufacturing processes and filling rates to suit the nature of the different products being produced for our customers.
In addition to dispensing the product into containers we have packaging equipment including capping machines that can pack on to shrink wrapped trays or into shipping cartons. Once palletised, the loaded pallets can also be stretch-wrapped or strapped as required for transit.
Working with liquid silver matrix is just one example of where having the right liquid filling equipment – and the experience to use it correctly – makes the difference between a product that fills cleanly and consistently and one that doesn’t.
Grotech handles liquid filling projects across a wide range of formulations and pack sizes – from straightforward repacking jobs to technically demanding briefs like this one. If you’ve got a liquid product that needs filling, blending or packing, we’d be glad to talk it through.
