Sachets or Cartridge: Which Packaging to Choose for Your Sealants?

Sealants are essential materials in many sectors such as construction, renovation, and DIY. Their performance and effectiveness depend not only on their chemical formulation but also on the type of packaging used. In this article, we will compare two of the main packaging formats available on the market: sachets and cartridges. Each format has distinct characteristics that influence the choice of professionals and individuals based on their specific needs.

Advantages

1. Reduction of Plastic Waste: Sachet packaging is often favored by those looking to reduce their environmental footprint. This format uses significantly less plastic than rigid cartridges, limiting the amount of waste generated after use.
2. Larger Capacity: Sachets typically hold between 400 and 600 ml of sealant, compared to around 300 ml for cartridges. This larger capacity is ideal for large-scale projects where a significant amount of product is needed.
3. Less Product Waste: Thanks to the flexibility of sachets, almost all of the contents can be extracted, reducing product waste—a key factor in maximizing cost-efficiency.
4. Optimized Transport and Storage: Lighter and less bulky, sachets offer a logistical advantage for both distributors and end users in terms of storage and transport.

Limitations

1. Tool Compatibility: One of the main barriers to adopting sachets is the need for specific applicator guns, which are often more expensive than those compatible with cartridges.
2. Reduced Handling Precision: The flexibility of sachets can make it harder to control the application of the sealant, particularly for tasks requiring a high degree of precision.
3. Risk of Air Bubbles: Some sachets lack an integrated air evacuation system, which can cause air bubbles during application, affecting the quality of the final finish.

Advantages

1. Precision Application: The rigidity of cartridges allows for more precise application, which is essential for tasks requiring fine detail, especially in finishing work.
2. Standardized Compatibility: Cartridges are compatible with a wide range of caulking guns readily available on the market, usually at an affordable price. This makes them ideal for a broad audience, from DIY enthusiasts to professionals.
3. Product Protection: Thanks to their rigid structure, cartridges provide better protection for the sealant against mechanical damage and contamination, ensuring optimal product preservation.
4. Control of Air Bubbles: Cartridges are often designed to minimize air bubbles during application, ensuring a higher quality seal or bond.

Limitations

1. Environmental Impact: Compared to sachets, cartridges generate more plastic waste, making them less eco-friendly.
2. Limited Capacity: With a capacity of 300 ml, cartridges may require multiple units for larger projects, increasing both costs and waste.
3. Product Waste: The rigid shape of cartridges often makes it difficult to extract all the sealant, leading to notable product waste.

If you need to switch between these two packaging types, the ideal solution is to use applicator guns compatible with both formats. At Acrom, we offer a range of COMBI guns, compatible with both sachets and cartridges. Available in manual, electric, and pneumatic versions, these guns provide the flexibility needed to use both packaging types without having to invest in multiple tools.

Choosing between sachets and cartridges depends largely on the specific requirements of your project. Sachets are more environmentally friendly, more economical in terms of product waste, and offer a larger capacity, making them ideal for large-scale projects. In contrast, cartridges stand out for their durability and precision, making them better suited for tasks requiring optimal control and finer application.

Whatever your choice, at Acrom, we have the solutions you need to make your work easier and optimize your results. Feel free to reach out to us for more information on our products and application tools.
