OK Compostable Standard: decompose over 90% in 180 days and leave no toxic residuals
To achieve this standard, the thickness of the packaging material will vary the result, because normal household compost condition is not strong, therefore only thinner than 60μm can achieve the standard to be called “Certified” Home compostable. For our film thicker than 60μm and thinner than 120μm. On one important note that it is certified as Industrial compostable and doesn’t mean it is not “Home compostable”. In fact, they are home compostable too, it just take longer time as the compost condition (acid, micro decomposer, water, sunlight, pressure etc…) is not enough for the pouch decompost in 180 days 90% but longer.
