6 Critical Powder Packaging Points to Consider

There are several factors that are vital and should be taken into account if you are planning to undertake packaging of powder products.  Powder packaging materials and powder packing machines are available in different variations which offers you an array of products to choose from. The factors that should be considered include the following six steps.

1. Know Powder Characteristics

The type of product you have is key when determining the most appropriate powder packaging machine for your applications. Although there are general types of equipment that are compatible with a wide range of products there are a few specialized packaging machines designed for specific types of powders. Powder characteristics include;

Free-flow Powder

Powder is characterized as free-flowing when it can flow through a very small opening only relying on gravity. Even when stored under unfavorable conditions such as 75 percent atmospheric humidity and stored in thin layers, this type of powder retains its ability to flow freely through miniature orifices as small as 6mm in diameter.

Non-Free Flow Powder

This powder variation has a much higher cohesive force and tends to retain the shape of an object it’s pressed against for example if you grip it in your hands it retains its shape. This type of powder typically has specialized equipment for packaging as it may prove difficult for general powder packaging machines.

Powder Bulk Density

Powder bulk density is a measure of the actual mass of the product in relation to its volume and this ratio also factors in the void in between the particles of the powder. This property is important when it comes to packaging as it factors in on the flow characteristic of your product. It also helps determine how efficient your packaging and filling equipment will be.

The weight which is essentially the volume of the product dispensed is vital in the overall packaging container as well as customer satisfaction in terms of product portion. The type of powder packaging material also factors in the overall weight of the product. It is important to ensure that you accurately dispense the stated product in their corresponding containers as it may lead to legal problems in case there are inconsistencies.

2. Choose Appropriate Packaging Container

3. Consider Powder Filling Technology

There are various powder-filling technologies that are suited for different types of powders and are used to characterize filling machines. Understanding how each method works is important as it will help you select the, most appropriate filling method for your applications. These methods include e;

Gravimetric Powder Filling

This is a highly efficient dispensing method that relies on the weight of the powder to accurately fill the desired containers. It is typically incorporated into an automated system that requires no contact with the product making it ideal for applications that include powders with abrasive properties such as pharmaceuticals as well as food products that can easily be contaminated.

Volumetric Powder Filling

In volumetric filling, the weight of the powder is first accurately measured before getting dispensed into tits respective containers. This filling method is very precise and relies on its sensors and control panels to properly function minimizing manual input.  They are used to fill a wide range of containers and can be used for abrasive powders, food, and pharmaceuticals.

4. Choose Efficient Powder Filling Machine

It is important that you select a powder-filling machine that takes all your application needs into consideration. This will ensure that you run more efficient and productive operations. You should consider these factors when selecting the most appropriate filling machine for you.

Powder Product Characteristics

Different powders have different characteristics which may require specialized filling machines. For example, powder that is free-flowing efficiently be dispensed by the gravimetric filling machine as it also relies on gravity to aid its dispensing. Therefore, the size, shape, and flow ability of the powder will directly influence the type of filling machine you require for the application.

Level of Accuracy

Precision is vital for specific industries such as pharmaceuticals and it is therefore important to select a filling method with an enhanced accuracy. When it comes to accuracy in terms of weight technology such as the volumetric filling machine is generally preferred as it ensures that only the desired volume of product is dispensed into its corresponding containers.

Types of Packaging Containers

The different types of containers come in various shapes and sizes and are designed from different materials. It is therefore important that you select a filling method that is compatible with your desired containers. For example, a machine that is used to fill bottles may not be useful when filling sachets.

5. Know your Industry

There are a broad range of industries that deal with powdered products. These industries include the following;

  • Pharmaceuticals: Different types of medicine and other health products are produced in powder form. These products often require precise measurements and the packaging materials used should have great barrier protection to protect the sensitive contents automated systems are preferred for this type of product.
