National Packaging Systems have supplied many systems to a wide variety of satisfied customers around the globe, who have packaged products ranging from cosmetics to charcoal.

The choice of packaging machinery should include: technical capabilities, labor requirements, worker safety, maintainability, serviceability, reliability, ability to integrate into the packaging line, capital cost, floor space, flexibility (change-over, materials, etc.), energy usage, quality of outgoing packages, qualifications (for food, pharmaceuticals, etc.), throughput (speed requirements), efficiency, productivity, ergonomics, return on investment, etc.

 NPS Packaging machinery can be:

  1.    1. purchased as standard, per catalogue
       2. purchased as custom-made or custom-tailored to specific operations.

Various levels of packaging line automation can be achieved using programmable logic controllers and robotics.


The first step in deciding on the correct packaging system is to classify the product into the following  3  groups -


Product Group Sub Group Examples
POWDERS Non Compressible Milk powder
    Soups and soyas
    Cool drink powders
    Fine maize meal
  Compressible Washing powders
GRANULAR Grains Rice
    Maize grit and meal
  Delicate products Chips / snacks
  Other Instant coffee
    Wrapped products
    Sticky products
    Non uniformed products
LIQUIDS Free flowing Juices
  Viscous Creams
    Peanut butter
    Steak and kidney pie fillings


The next step is to decide on the packaging style and type of Film that is suitable for your product.
A wide variety of pack styles can be catered for in the design of a bag for every conceivable product. The most commonly used in the industry are -:

The pillow pack The block bottom The quad Strip Pack The pyramid pack

A variety of film (material) types are available, and a choice of the most suitable film needs to be made from one of the two main groups.

1. Straight Poly Films

Monolayer sealant films

2. Laminate Films

The highest performance, most prevalent film, used in demanding applications.

Sub Categories (2 ply films)


A typical packaging process is composed of various machines which together make up a complete system. A description of a typical system would be as follows.

Feeding system
This machine will convey your product from the manufacturing process or bulk stores into the filling hopper of the filling system.  Various systems are available depending on the type of product you are trying to convey, how often you may change products/ flavours etc. These machines are often controlled by a level sensor in the filling systems bulk hopper.

Filling system
This machine will measure out the correct quantity of product required for each individual bag / closure. The machine will release the product once a signal has been received from the bagging machine in the case of a full automatic system, or on command from the operator, in a semi automatic system. In many cases the accuracy of these machines is dependent on being consistently fed by the feeding system. Various machines are available and the correct choice will depend on the product being packed, the accuracy required, speed etc.

Bagging / Form fill and seal
These machines actually make the closure/ bag from a roll of plastic film, fill the bag with the required product and seal it into an completed bag. There are many different types of machines available and the type of bag / sachet, size / volume of bag, required output, and type of product, will determine which machine will be the most suitable choice

Once the completed bag exits the machine it will drop the bag onto a discharge conveyor to be conveyed to a point where it will be packed in its end of line packaging.

End of line packaging
Here the individual packages get collated in to either bales, boxes, or directly onto a pallet. The machine chosen depends on the level of automation required. 

A wide range of accessories as well as custom modifications can be undertaken to tailor the system to meet and exceed the clients full requirements.
