We consider ourselves the powder packaging experts, and enjoy creating custom packaging solutions for our clients.
Easy to use and offering a great product, convenience packaging for powders is experiencing rapid growth. LinPackmachines are easy to operate, conveniently integrate into your packaging operations and produce flawless results. Our packaging machine line-up includes models specifically designed to create industry-standard and consumer-favorite sized stick packs.
Larger bags of powders for spices, salt or food service use are perfectly made by our LinPack machines. We provide complete powder packaging systems for all powders and granulars, whether dusty, free flowing, or non-free flowing.
Whether it be spices, flour, drink mixes, or non-food powders like enzymes or chemical additives. With convenience products becoming increasingly popular, we expect the powder packaging market to grow even more in areas like pre-packaged spice blends to add to meals, instant coffee and drink mixes, and single-serving nutritional powders. When it comes to powder packaging, there are three main things your packaging equipment manufacturer needs to know to provide the best packaging solution for your specific application.
A powder product is considered free-flowing when its particles are not cohesive. Examples of this are granulated sugar or table salt, which 'flow freely' when dispensed. Adding extra pressure usually will not compact these types of powders, and they usually don't hold their shape when manipulated.
A powder product is considered non-free-flowing when the particles are cohesive. Examples of this are brown sugar or flour, which tend to hold their shape when manipulated and can be compacted under pressure.
Determining whether your product is free-flow or non-free-flow is vital to the success of your POWDER PACKAGING PROJECT. In particular, it affects the type of filler your product requires to properly dispense your powder product into its packaging. Free-flowing product easily falls with the force of gravity while non-free-flowing product needs to be properly compacted and 'helped along' during packaging because of its cohesive properties, necessitating entirely different filling systems to convey the products properly. In general, free-flow powder packaging projects can utilize volumetric or free-flow auger product fillers, while non-free-flow powder packaging necessitates an auger filler specialized to properly dispense cohesive products.
Consider a non-free-flow powder product like flour. When flour is dispensed, inevitably a dust cloud is formed. Anyone who has ever worked with this type of product knows how far these particles can travel, and how they cling to almost any surface. Now consider this in the context of powder packaging machinery; serious mechanical issues can occur as a result of loose airborne particulates. Thus, certain powder packaging machinery options are recommended WHEN A POWDER PRODUCT IS DUSTY:
· An enclosed jaw drive on the packaging machine, will protect integral moving parts that drive the sealing jaws.
· A packaging machine IP RATED to be dust protected or dust tight, will prevent particulates from entering machine enclosures.
· A dust extraction device will help remove airborne particulates at the source.
· A dust hood will help contain dust ejected when the product is dispensed into the package.
The bulk density of a powder product conveys both the 'flowability' of the powder and how much it may compact when under pressure. A basic formula used to compute bulk density is total mass divided by total volume, although there are other methods and devices that can compute bulk density to a higher accuracy. Bulk density is customarily represented as g/cm3.
Free-flowing, dry products like granulated sugar usually will not compress very much and have a low bulk density. Non-free-flow, cohesive products like brown sugar have a higher bulk density that will get even higher when compacted.
So what does bulk density have to do with powder packaging machinery? As an extreme example: Consider packaging 50g of moist sand vs. 50g of roasted coffee beans. Both weigh the same at 50g, but the package dimensions and types will be vastly different because of the amount of empty space around and inside of the products. The sand contains less empty space and is more compressed within the package, allowing for a smaller pouch. The coffee beans contain much more empty space and do not compress much at all, necessitating a much larger pouch. This is where bulk density becomes an important consideration when packaging powders: It has a direct influence on pouch sizes and attributes, the type of filler required, as well as the packaging speeds that can be attained.
