Coffee bags
For conservation of coffee aromas, pockets with one-way flower flower. Valve reliably controls the release of oxygen, carbon dioxide or steam. Coffee bag equipped with aluminum creates an excellent air and humidity layer. Oxygen does not impede the aging of the coffee beans and roasted coffee so does not lose their typical scent and taste.
The aluminum layer is also fully replaced by a combination of two layers of BOPA / CPP foil that creates a barrier fully comparable to aluminum. In addition, few CO2 emissions are produced when liquidating these pockets. Pockets can be sealed with pulse welding or welding pliers. Re-shutting zip keeps freshness of coffee even after the bag open.
