Chapter 04 · The Korina Standard
Solventless is only the beginning.
What touches your rosin matters.
We didn't stop at eliminating chemical extraction solvents. We paid attention to the materials used in the pressing process — choosing stainless steel filtration bags and stainless steel pressing surfaces instead of conventional nylon pressing bags.
From plant to person
Everybody talks about what's in their rosin.
We talk about what touches it.
Solventless extraction
Produced using only heat and pressure. No chemical solvents. No hydrocarbons.
Stainless steel filtration bags
Premium stainless steel mesh bags. No nylon bags. No plastics.
Stainless steel surfaces
Rosin only touches stainless steel. No parchment paper. No synthetic materials.
No petrochemicals
Designed to avoid petroleum-based materials at every stage, in accordance with the NoPetroChem standard.
The difference
Conventional vs Korina 420.
| Conventional | Korina 420 | |
|---|---|---|
| Filtration bags | Nylon pressing bags | Stainless steel mesh bags |
| Pressing surface | Parchment paper | Stainless steel |
| Extraction | Often solvent-based | Heat and pressure only |
| Petroleum-based materials | Common in contact | Avoided at every stage |
Precision materials.
A purer process.
Our patented extraction and collection technology uses stainless steel filtration bags and stainless steel pressing components to maintain the purity of the rosin from start to finish.
Korina's technology is designed around solventless production and deliberate material selection — protected by multiple patents in the U.S., Canada and Europe.
Our standard is built on intentional choices, not unnecessary complexity.
