Today, brands and consumers are more conscious than ever before about environmental issues linked to plastic pollution, and they look for more eco-friendly alternatives to plastic products.
A competent manufacturer should always look for ways to satisfy demand and find innovative solutions. That is why we created Legnavis: the most sustainable and plastic-free solution for packaging.

How threaded wooden caps make your products 100% sustainable
The demand for products that don’t have a negative effect on the environment and are produced in a sustainable way is constantly growing.
As consumers want to find eco-friendlier items on store shelves, brands and companies look for ways to satisfy them to be competitive in the market, and they look for suppliers that can offer new solutions for a greener packaging.
The idea of creating 100% sustainable threaded wooden caps for packaging arose from this need.
Threaded wooden caps already existed, but they didn’t satisfy customers’ needs, as they were subjected to wear over time, losing their smooth hermetic closure, and they were not completely eco-friendly.
So far, in fact, wooden caps in cosmetics have needed an internal plastic threaded capsule to ensure perfect closing. Now, this plastic part and the associated glue for it can be definitively eliminated resulting in a completely eco-friendly object.
What distinguishes a standard threaded wooden cap from Minelli’s?
Look at the picture below:
A regular thread starts at zero level tangentially to the edge of the cap and then rises progressively until it reaches its maximum section height. Since wood is a “soft” material, such structure is not resistant.
Minelli’s wooden thread starts at its maximum section height right from the beginning, so it is much more resistant and durable; such thread will maintain its functionality even when frequently screwed and unscrewed and protects the product from contamination and leakage.
A resistant wooden cap that can be easily combined with other materials without losing its functionality is essential (cosmetic bottles are often made of glass, for example, and the cap must be suitable for them).
To create such a strong and durable threaded cap, you need innovative tools and specific CNC (computer numerical control) machines as well as competency, expertise, and both manual and automatic quality control during production.
Minelli was a pioneer in introducing and patenting a completely eco-friendly threaded cap without plastic or glue. We were the first and only company that patented this innovative thread in January 2020, and we are very proud of this completely sustainable, elegant, and customizable solution.
We can supply it in almost any dimension and shape, wood essence, and finish according to your clients’ requests. Our R&D department is constantly working on developing new water-based lacquers that are eco-friendly and safe.
We must underline that in case a sealing gasket has to be present it can be completely removed, as we include in the internal cap design a specific undercut.
Today, you can offer an even more sustainable solution combining Legnavis with cork-sealing discs
Sealing discs are usually made of plastic, but to increasingly meet the need for sustainability, now you can choose completely ecological sealing discs made of cork that are extremely functional and customizable according to your clients’ requirements.
Discs made of cork exploit the natural compressibility of the raw material to seal the lid and avoid product leakage without using plastic, glue, or resin.
Combining threaded wooden caps with a cork-sealing disc means offering 100% sustainable packaging for cosmetics and ensuring maximum functionality and performance.

This solution can actually represent a turning point in the pursuit of completely sustainable products.
However, the experience and reliability of the manufacturer are crucial
The wood maker must know the typical tolerances required by wood when milled to be coupled with other materials in the final product and how to set them to guarantee maximum precision and adaptability.
An expert supplier has special in-house drying chambers to ensure the correct degree of dryness of the raw material before moving to production and avoiding that shape and volume of wooden caps warp over time, which could cause possible problems when used.
Moreover, you must ensure it employs sustainable practices during the production process and uses only FSC/PEFC-certified wood to create its objects.
Creating cosmetic wood packaging, though, is not enough to offer sustainable products.
Since 1937, Minelli S.p.A. has designed, developed, and manufactured premium custom-made wooden components and products for many different brands and markets, and the quality of its objects is recognized all over the world.
In 1999, we were among the first to be certified by the FSC when it was not yet a standard. Today, we are also PEFC certified.
