This comparison explores the technical capabilities of both formats, helping you determine which packaging technology delivers the optimal balance of efficiency, cost-effectiveness, and consumer convenience for your specific product requirements.

 

1️⃣ Understanding Stick Pack and Sachet Packaging Fundamentals

In the world of single-serve packaging, stick packs and sachets have revolutionized how products reach consumers. These compact formats offer efficiency, convenience, and extended shelf life across multiple industries. As someone who’s worked with these technologies for years, I’ve seen firsthand how the right packaging choice can make or break a product launch.

“Stick pack and sachet packaging systems offer distinct advantages for different products, with stick packs excelling in portion control for powders and sachets providing versatility for thicker substances.

What is Stick Pack Packaging? Slim Design and Single-Serve Precision

Stick pack packaging represents the slimmer, more elongated option in single-serve formats. Typically measuring 7-10mm in width and 80-200mm in length, these narrow tubes excel at dispensing powders, granules, and thin liquids. The stick pack machine creates these sleek packages through a vertical form-fill-seal process, producing packages that are “game changers” for portion-controlled products.

The narrow profile of stick packs makes them ideal for products where precise dispensing matters. Coffee, sugar substitutes, protein powders, and pharmaceutical formulations benefit from the controlled pouring that stick pack packaging provides. Modern stick pack machines can produce up to 1,200 units per minute while maintaining seal integrity and fill accuracy.

What is Sachet Packaging? Versatile Format for Thicker Products

Sachet packaging offers a wider, more rectangular profile compared to stick packs. Typically measuring 30-100mm in width, sachets accommodate thicker products like creams, gels, and pastes that wouldn’t flow easily through narrower openings. Sachet machines create these packages using similar sealing technology but with modified forming components to allow for the wider format.

Sachets excel in applications like cosmetics, condiments, personal care products, and pharmaceutical creams where product viscosity demands a wider opening. The larger surface area also provides more space for branding and product information, making sachets favored in retail environments where shelf appeal matters.

Key Structural Differences: Shape, Sealing, and Material Usage

The fundamental differences between these formats extend beyond mere dimensions. Film usage efficiency varies significantly—stick pack machines typically consume 30-40% less packaging material than comparable sachet machines for the same volume of product. This translates to reduced material costs and environmental impact.

When manufacturers are evaluating packaging solutions, understanding the technical distinctions between stick pack and sachet machines becomes critical for operational success. Both technologies utilize similar principles but differ significantly in their execution, processing capabilities, and optimal applications.

The efficiency gap between stick pack and sachet machines stems primarily from their mechanical design differences, with stick pack machines typically achieving higher production speeds for powdered products.

Stick Pack Machines: VFFS Technology and High-Speed Production

Stick pack machines utilize vertical form fill seal packaging technology, where film flows vertically through forming shoulders that create the characteristic narrow tube shape. This vertical orientation optimizes gravity-assisted filling, particularly advantageous for free-flowing powders and granules. The stick pack machine’s slim profile enables multiple lanes of production—typically 8-12 lanes operating simultaneously.

Our VFFS 320S model exemplifies this efficiency, achieving production rates of 100 bags per minute across 10 lanes, translating to 1,000 individual stick packs per minute. This high-throughput capability makes stick pack machines ideal for large-scale production environments where speed and consistency are paramount.

Sachet Machines: Handling Viscous Products and Wider Sealing Areas

Sachet machines, while also utilizing VFFS principles, are engineered with wider forming sets and more robust sealing mechanisms to accommodate thicker, more viscous products. The wider format necessitates stronger sealing pressure and often longer dwell times to ensure package integrity. This fundamental design difference affects both operational parameters and production throughput.

The wider sealing area of sachets requires more precise temperature control across a larger surface, with typical sachet machines featuring 4-6 production lanes compared to stick packs’ 8-12 lanes. This configuration difference directly impacts overall production capacity while providing the versatility needed for creams, gels, and paste products.

Production Speed Comparison: Bags/Minute Metrics

When evaluating production efficiency, the bags-per-minute metric provides a clear comparison point. However, this metric must be contextualized within the specific product being packaged and the physical constraints of each technology.
