In short, sachet filling and packing machines are designed to handle a wide variety of liquid, paste, and high-density products. They are commonly used for single-serving or sample-sized packaging of items ranging from food products like ketchup, honey, and fruit jam to personal care items like shampoo, hand sanitizer, and facial creams.
The key determining factor isn't the specific product itself, but its physical state. These machines are engineered to manage different levels of viscosity, from thin liquids to thick pastes and spreads.
The Core Principle: Product Viscosity and Consistency
The versatility of a sachet filling machine comes from its ability to handle products with different physical properties. The suitability of a product for this type of packaging is almost entirely dependent on its flow characteristics.
Low-Viscosity Liquids
These are thin, free-flowing products that are easily pumped through the machine's filling system.
Examples include hand sanitizer and liquid hair shampoo, which require precise volumetric control to prevent over- or under-filling the sachet.
Medium-Viscosity Pastes and Creams
These products are thicker and require more specialized systems to ensure they are dosed accurately without creating air pockets.
Facial creams and many types of chilli sauce fall into this category, demanding a filling mechanism that can handle their consistency.
High-Viscosity and Dense Spreads
These are the thickest products, which resist flowing and require powerful pumping mechanisms.
Products like honey, marmalade, fruit jam, and ketchup are examples of high-density spreads that need robust machinery to handle their thick texture.
Common Applications by Industry
While the product's physical state is the technical determinant, these machines see widespread use across several key industries. This demonstrates their adaptability to different market needs and packaging standards.
Food and Beverage
This is a primary market for sachet packaging, focusing on single-serving condiments and samples.
Common applications include ketchup, honey, chilli sauce, and various jams.
Cosmetics and Personal Care
Sachets are ideal for travel-sized products, samples, and one-time-use treatments in this sector.
Typical products include hair shampoo, facial cream, and hand sanitizer.
Pharmaceutical and Chemical
Though not detailed in the product examples, sachet machines are widely applied in the pharmaceutical industry for gels and creams, as well as in the chemical sector for specific formulations.
Understanding the Limitations
While highly versatile, these machines are not a "one size fits all" solution. The configuration required for one product type may not be suitable for another without adjustment.
The Myth of Universal Compatibility
A machine optimized for a thin liquid like hand sanitizer will likely struggle with a thick paste like fruit jam.
The pump, nozzles, and filling mechanism are often tailored to a specific range of viscosity.
The Importance of Machine Specification
When sourcing a machine, it is critical to specify the exact products you intend to pack.
This ensures the machinery is equipped with the correct components to handle your product's specific density and flow characteristics accurately and efficiently.
How to Apply This to Your Product
Your product's physical properties will determine the type of sachet machine you need.
- If your primary focus is on thin liquids: Your priority should be a machine with a highly accurate volumetric or gravity-fed filling system to ensure consistent dosing.
- If your primary focus is on thick pastes or creams: You must select a machine with a powerful piston or rotary pump designed to handle high-viscosity materials without failure.
- If your primary focus is on versatility for multiple products: Look for a semi-automatic or modular system that allows for interchangeable pumps and nozzles to adapt to different product types.
Ultimately, matching the machine's technical capabilities to your product's specific consistency is the key to successful sachet packaging.
