Burundi Customer Case: 20g Washing Powder Sachet Packing Machine with Cup Dosing

Videos

Project Overview

Customer Requirement

The Burundi customer wanted to produce 20g washing powder sachets for the local detergent market. Small sachets are common in many African markets because they allow consumers to buy daily-use detergent powder at a lower unit price.

The customer’s key requirements included:

• 20g filling weight

• pillow bag format

• volumetric cup dosing

• 120mm bag width

• 100mm bag length

• 260mm film width

• 12 connected bags per strip

• serrated cutting

• French / English / Chinese interface

• 3 phase 380V 50Hz power supply

For this application, Samfull selected a Model 61 cup-type small vertical packing machine, which is suitable for compact, economical, and stable sachet production.

Why Cup Dosing Was Selected for 20g Washing Powder

For this project, the machine uses a volumetric cup dosing system. This is a practical filling method for washing powder when the product density is relatively stable.

The production requirement shows that 20g washing powder is approximately 36ml, so the filling cup can be designed according to the actual material volume.

Cup dosing is suitable for:

• washing powder

• laundry detergent powder

• cleaning powder

• free-flowing detergent granules

• small granular powder products

Compared with weighing systems, cup dosing has a simpler structure and lower machine cost. For many daily chemical sachet projects, especially small-dose washing powder packs, it is a practical entry-level solution.

Pillow Bag Design for Detergent Powder Sachets

The customer selected a pillow bag format, which is widely used for low-cost daily chemical packaging.

The final sachet specification is:

• Bag width: 120mm

• Bag length: 100mm

• Film width: 260mm

• Upper and lower seal width: 10mm

• Cutting style: serrated cut

• Easy tear notch: not required

• Connected strip: 12 bags per strip

This bag size gives enough space for detergent branding, washing instructions, and product information while keeping the package economical for mass-market retail.

12-Bag Linked Strip Function

A key feature of this project is the linked bag function.

The customer required 12 bags per strip, meaning the machine can produce connected sachets instead of fully separated single bags.

For washing powder products, this format is useful because:

• retailers can display connected sachets easily

• distributors can count and pack products faster

• consumers can tear off one sachet when needed

• small shops can sell individual packs conveniently

• bulk handling becomes more organized

This function is especially practical for detergent powder distribution in traditional retail markets.

Serrated Cutting for Easy Separation

The machine uses serrated cutting, which creates a toothed edge on the sachet. Even without a separate easy-tear notch, serrated cutting helps consumers separate or open the sachet more conveniently.

For small detergent powder sachets, serrated cutting is a cost-effective and reliable option because it supports simple retail use while keeping the machine configuration practical.

Machine Configuration Highlights

Volumetric Cup Dosing

The cup dosing system is designed according to the customer’s 20g washing powder volume. It provides a simple and stable filling solution for daily chemical powder products.

Pillow Bag Sealing

The machine forms pillow bags from roll film, fills the detergent powder, seals the bag, and cuts the finished sachets automatically.

Linked Bag Production

The machine supports 12 connected bags per strip, matching the customer’s retail and distribution requirement.

Multi-Language Interface

The HMI supports Chinese, English, and French, which is suitable for the Burundi market and local operators.

Export Power Standard

The machine is configured for 3 phase, 380V, 50Hz, matching the customer’s factory power condition.

Export Wooden Case Packing

The machine is packed in an export wooden case for international transportation.

Quality Control Points

For washing powder sachet packaging, the main quality points include:

• stable 20g filling volume

• smooth powder feeding

• firm top and bottom sealing

• stable vertical sealing

• accurate bag length control

• neat serrated cutting

• correct 12-bag strip counting

• reduced powder leakage

• stable film pulling and forming

Because detergent powder formulas may vary in density, particle size, and flowability, Samfull normally recommends confirming the actual material and film before final machine adjustment. This helps ensure the cup volume, bag size, sealing temperature, and cutting performance match the real production condition.

Suitable Applications

This machine is suitable for small-dose sachet packaging of daily chemical and free-flowing powder products, including:

• washing powder sachet

• laundry detergent powder sachet

• cleaning powder sachet

• detergent granule sachet

• bleaching powder sachet

• small household chemical powder sachet

With different dosing systems, the machine platform can also be adapted for other powder or granular products.

Why This Case Is Valuable

This Burundi project shows a practical solution for customers who need an economical small vertical washing powder sachet packing machine.

The value of this case is the matching between product, market, and machine configuration:

• 20g small-dose sachet for daily-use detergent

• cup dosing for cost-effective filling

• pillow bag for economical packaging

• 12-bag linked strip for retail display and easy counting

• serrated cut for convenient separation

• French interface for local operation

• compact vertical machine for small factory production

For detergent powder producers and local distributors, this type of machine is a practical way to start or expand small sachet production.

Conclusion

This Burundi customer case demonstrates a cost-effective packaging solution for 20g washing powder sachets.

Samfull supplied 1 set of Model 61 cup-type small vertical packing machine with volumetric cup dosing, pillow bag sealing, serrated cutting, and 12-bag linked strip function. The machine was configured with 260mm film width, 120mm bag width, 100mm bag length, and 3 phase 380V 50Hz power supply.

For customers looking for a reliable washing powder sachet packing machine, laundry detergent powder packing machine, or small vertical powder sachet machine, this case provides a clear reference for similar daily chemical packaging projects.
