The design of packaging and dispensing systems can go a long way in supporting adhesive manufacturers and end users in the pursuit of increased efficiencies. Particularly with the optimal filling and application of 2-component adhesives, it’s fundamental to obtain reliable bonds. medmix reports that its latest Mixpeel coaxial cartridge offers high performance, reliability, and ease of use without compromises.
Adhesive, sealant, and caulking formulations are continuously improving to deliver optimal solutions for a wide range of applications and industries, not just building and construction. These new products need suitable packaging and dispensing systems that help adhesive manufacturers easily and reliably pack their formulations while minimizing waste and allowing end users to efficiently apply the products.
According to medmix, it developed the new Mixpeel based on the design principle that “form follows function.” A key feature is compactness and convenience, as the system can hold 2-component adhesives in a 1-component-style cartridge. In this way, end users can use simpler single-component dispensers rather than multi-component tools. The new Mixpeel cartridge is compatible with most 1-component dispensers available on the market, offering flexibility and adaptability for a wider range of users and applications.
The 2-in-1 design also includes an innovative cutter unit. Four cutter blades “cut-peel” the inner tube apart and push the sliced inner tube parts toward the outer tube. This technique enables the use of a single-component dispenser in combination with a 2-component cartridge.
The 2-in-1 compact design of Mixpeel offers substantial waste reductions, lowering the environmental impact of the system. The solution was designed to minimize the volume of adhesive loss in discarded cartridges. To further reduce waste, Mixpeel cartridges can be resealed and stored if they are not empty after use; the fitted closure avoids contamination and adhesive hardening.

The design of the cartridge uses less packaging material than traditional coaxial systems while accommodating larger amounts of adhesives vs. comparable cartridges available on the market. medmix reports that its solution fits 280 mL of 2-component adhesives into the cartridges, as opposed to the conventional 250 mL. This leads to substantial savings in packaging materials and a positive knock-on effect toward reducing waste and carbon footprints.
Shifting the Outlet Position
Ensuring optimal functionality was also the reason behind the geometry of the cartridge outlet, which is decentralized and features a large side-by-side opening. This design supports adhesive manufacturers by allowing cartridges to be front-filled.
The decentralized outlet position reduces the likelihood of friction issues and air being trapped in the cartridge. The components being filled into the tubes follow a straight path, without changes in direction that can affect optimal filling. Similarly, when it comes to dispensing, no air bubbles are formed within Mixpeel.
In addition, the big aperture increases the adhesive liquid flow rate during filling, allowing adhesive manufacturers to fill the cartridges faster and more efficiently. The Mixpeel concept also supports back-filling, when this option is preferred. In this case, adhesive producers can benefit from a lightweight and reliable system that can be filled again without any trapped air. Excellent mixing performance and accurate dispensing are provided by the system’s QUADRO mixing tips, which fold the two adhesive components together repeatedly until a homogenous mixture is prepared for delivery.

Finally, end users that choose Mixpeel need to apply less dispensing force. Tests show that the dispensing force required with high-viscosity materials is 35% lower than comparable cartridges available on the market.
Efficiency through Design
Efficient design of adhesive packaging and dispensing is key to boosting productivity, reliability, and performance. By relying on leading experts in applicator systems and their solutions, cutting-edge adhesives and cartridges can work together to meet demanding market requirements and support even the most challenging applications.
