Whatever your production requirements, we have the packaging solution to match.
Small portions demand tighter control of the formulation
With stevia, the packaging challenge is not simply to dose a powder accurately. The physical volume of each portion depends on how the sweetening ingredient is formulated, which carrier is used and how consistently the blend behaves during feeding.

Why Universal Pack for stevia packaging?
Stevia is already part of Universal Pack’s sugar and sweetener application portfolio, with real pack samples produced using Universal Pack technology. For free-flowing formulations, the basculating dosing system provides a proven starting point for developing compact single-dose stick packs and sachets.
The machine is then configured around the finished stevia formulation rather than the ingredient name alone: actual dose, bulk density, flow behaviour, pack volume and required output all become part of the engineering process.
Basculating dosing for free-flowing stevia formulations
Universal Pack uses oscillating volumetric cups with micro-adjustable dose control for free-flowing products such as stevia. The dosing volume is configured around the actual formulation and target portion.
Low-dose packaging from a platform starting at 0.1 g
Universal Pack’s sugar and sweetener platform covers applications from 0.1 to 100 g per pack, subject to product characteristics and machine configuration. This is particularly relevant when a stevia formulation requires a significantly smaller portion than conventional sugar.
Test the finished formulation, not only the ingredient
The internal Universal Pack laboratory can test the customer’s actual product and laminate before final machine engineering. For stevia, this helps evaluate flowability, bulk density, dose behaviour and packaging material under representative conditions.
Turn individual portions into a controlled carton count
When stevia packs need to be supplied in fixed-count cartons, Universal Pack can integrate primary packaging with patented counting and cartoning technology. Inspection, coding and weight-control systems can also be incorporated according to project requirements.

Technical Project Assessment
Stevia concentration alone does not define the packaging process: the finished formulation, carrier system, bulk density, particle distribution and target portion determine how the product behaves inside the volumetric dosing system. These variables are evaluated together before defining dosing volume, pack geometry and machine configuration.
| What we evaluate | Key project considerations |
|---|---|
| Is the product a concentrated stevia ingredient or a finished tabletop formulation? | The answer defines the actual quantity and physical volume that must be dosed into each pack and determines whether the proposed configuration is appropriate for the finished product. |
| What quantity of the finished stevia formulation belongs in each pack? | The target weight establishes the required dosing volume and is used together with bulk density to size the volumetric dosing setup. |
| Which carrier or bulking system is used in the formulation? | The carrier can strongly influence bulk density, particle size and flow behaviour, so the finished commercial formulation should be assessed rather than the stevia component in isolation. |
| How stable is the formulation’s bulk density? | Because the basculating system doses volumetrically, changes in bulk density can change the weight contained in a fixed dosing volume. Density consistency is therefore directly relevant to portion repeatability. |
| Does the finished formulation remain free-flowing throughout production? | Consistent natural flow is necessary for stable filling of the volumetric cups. Any tendency to cake, bridge or feed irregularly must be identified during product assessment. |
| Can the stevia blend segregate before it reaches the dosing cups? | If ingredients have different particle sizes or densities, separation can change the composition of individual portions. Blend homogeneity should therefore be verified under representative feeding conditions. |
| What particle-size distribution does the finished blend have? | Particle dimensions influence flow behaviour and how uniformly the volumetric cups fill and empty. The distribution should therefore be evaluated on the actual production formulation. |
| Are very fine particles generating dust around the filling area? | Fines can disperse differently from the main product fraction and may increase deposits around product-contact and sealing areas. Their behaviour is considered when defining product handling and machine settings. |
| Does static electricity affect product discharge? | Light or fine particles can adhere to surfaces instead of falling cleanly into the pack. If this behaviour is observed during testing, appropriate handling measures can be evaluated. |
| Does humidity alter the flowability of the stevia formulation? | If the blend absorbs moisture or agglomerates, changing environmental conditions can reduce the repeatability of volumetric filling. Production and storage conditions should therefore be considered during assessment. |
| What dosing-cup volume corresponds to the required stevia portion? | The appropriate cup volume is defined from the target weight and measured bulk density of the finished product and then adjusted to achieve the required portion. |
| How compact can the finished stick pack or sachet be? | The physical volume of the measured dose determines the minimum practical internal space required, while pack dimensions must also support reliable product discharge and sealing. |
| Will different stevia strengths or formulations run on the same machine? | Each formulation may have a different target weight, bulk density or particle profile and can therefore require dedicated machine recipes or dosing adjustments. |
| What barrier does the selected laminate need to provide? | The required protection is defined according to the formulation’s sensitivity to moisture, intended shelf life and storage conditions, together with sealability and machinability. |
| How will a very low finished-pack weight be verified? | If automatic weight verification is required, the selected checkweighing solution must be assessed against the actual total pack weight, required tolerance and line conditions. |
Faq
Which packaging machine is suitable for stevia?
Universal Pack multilane stick pack and sachet machines can package free-flowing stevia formulations using basculating volumetric dosing. The final configuration depends on the finished formulation, dose, bulk density and pack format.
Why does Universal Pack use basculating dosing for stevia?
The basculating system is designed for free-flowing powders and granules. Stevia formulations with stable free-flowing behaviour can naturally fill the volumetric cups, allowing the required portion to be set through cup sizing and micro-adjustment.
Can very small stevia portions be packaged?
Yes, subject to the actual formulation and machine configuration. Universal Pack’s sugar and sweetener platform covers applications starting from 0.1 g per pack.
Is pure stevia extract packaged in the same way as a tabletop stevia blend?
Not necessarily. The required quantity, bulk density and physical volume can be very different, so the actual finished product must be assessed before the dosing configuration is confirmed.
Why does the carrier used in stevia matter for packaging?
The carrier changes the physical characteristics of the finished blend. It can affect bulk density, particle size, flowability and therefore the volume required to produce the target pack weight.
Can different stevia formulations run on the same packaging machine?
Potentially, yes. Each formulation should first be assessed for dose, density and flow behaviour so that the necessary machine recipes and adjustments can be defined.
Can stevia be packaged in both stick packs and sachets?
Yes. The choice depends on the physical dose volume, desired pack proportions, branding requirements and production setup.
Can stevia sachets be made very small?
Potentially, but pack dimensions are not determined by product weight alone. The actual bulk volume, product discharge path and space required for reliable sealing also need to be considered.
Can dust from fine stevia formulations affect packaging?
Yes. A high proportion of fines can increase product dispersion around the dosing and filling area. This behaviour should be assessed using the actual formulation so that machine settings and handling can be adapted accordingly.
Can stevia packs be automatically inspected and coded?
Yes. Visual inspection and inkjet or laser coding systems can be integrated according to the quality-control and traceability requirements of the project.
Can sustainable films be tested for stevia stick packs?
Yes. Alternative packaging structures can be evaluated in the Universal Pack laboratory to assess machinability, sealing and the barrier performance required for the formulation.
Can stevia stick packs be automatically counted into cartons?
Yes. Universal Pack can integrate multilane primary packaging with patented counting systems and cartoning equipment to produce defined pack counts automatically.
