For the filling of small portion packs, it is often necessary to first form the parts of the packaging. We offer integrated tools for the forming of plastic and aluminum foil as well as paper and non-woven inserts.
Perfect forming with Rychiger tools
Having been involved in many development and industrial production projects, Rychiger has acquired huge expertise in forming. That is why we can offer optimized solutions for virtually all materials.
Filters made from paper or non-wovens
Cold or hot forming tools fold and shape the filter material for insertion into the coffee or tea capsule. By folding, the filter surface is increased, enhancing extraction. Excess material that cannot be stretched or shrunk is hidden inside the folds. Our forming technology for paper and non-woven filters has become the industry standard, and we are the preferred supplier of K-Cup contract packers.
Healthcare microfluidic applications sometimes differ greatly from each other. There are those where we seal two flat sheets together to form channels for liquids. The seal can be peelable (frangible seals) or non-peelable. Then there are applications in which an injection-moulded part is sealed with a film or with a counterpart. It can also be injection-moulded or bonded with a PSA (Pressure Sensitive Adhesive). Finally, there are applications where thin aluminium foils are shaped in such a way that they get a three-dimensional shape, which is used in microfluidics or lab-on-a-chip applications. Thanks to our experience from numerous development projects, we have found the optimal process for the heat transfer between the sealing tool and the foils for foil forming.
Food & Beverage pads
For pads, we seal foil to foil instead of foil to capsule. As the plastic foil enters the heated forming tools, it becomes formable. With this process, our machines produce smooth coffee pads, which have become a popular alternative to capsules.
Capsules and blister packs
During its startup phase, Rychiger produced deep drawing tools for the forming and shaping of aluminum. Today we apply this know-how by bringing flat aluminium foils into the correct shape with cold or hot tools - be it for coffee capsules or blisters for IVD applications. The latter are characterized by their highly precise and complex shape as well as the possibility of headspace-free filling. This is how unique projects with high value are created.
Alternative to injection molding
Formed foil packaging is a viable alternative to injection molding, as it requires less material and is more sustainable. In addition, the containers are formed just before they are filled, doing away with the costly transport of empties.
Take advantage of our experience
Do you wish to form a biodegradable or recyclable material? Does your product need to be filled into multi-layer foil containers including several barrier layers? Would you like to obtain a sample before making your decision? Then please contact us as early as possible during the development phase for your new packaging. We will then put our lab at your disposal, test your solution for proof of concept and make your product ready for serial production.
