Single-dose format
Each sachet protects one portion, avoiding repeated exposure from opening and closing a larger bag.
Graintact product platform
VitraLock™ single-dose coffee preservation.
A nitrogen-flushed, single-dose sachet system using SiOx Transparent Barrier Technology to help protect roasted coffee from oxygen, moisture, and aroma loss until brewing.
SiOx Transparent Barrier Technology
A glass-like mineral barrier for individual coffee doses.
VitraLock uses an ultra-thin silicon-oxide layer inspired by the protective properties of glass. Combined with nitrogen flushing and single-dose packaging, it creates a consumer-ready preservation format for coffee brands that want freshness to become part of the product experience.
Product logic
One sachet. One dose. One fresh brew.
Nitrogen flushed
Oxygen is displaced before sealing to help slow oxidation and protect delicate aromatic compounds.
SiOx barrier
A transparent silicon-oxide layer helps reduce oxygen and moisture transfer while keeping the format modern.
Brand platform
Graintact can adapt the technology for coffee brands that want a proprietary preservation story.
Brand application
Straight from the farm. Freshly Preserved.
For Paradise Horse, VitraLock protects a simple promise: coffee that feels as close as possible to the farm where it was grown. For partner brands, the same preservation platform can become a fully branded single-dose experience, with the sachet artwork, format language, and freshness story shaped around their identity.
