These pouches are made of several materials and therefore can be classified into different categories. The differences in these categories are determined by 'what it is made of' and 'how it is to be processed'. For example, there is much of demand for 'aluminum-free' pouches, but these are made of traditional plastic and are 'better' than bags with aluminum (more environmentally friendly). We also make pouches from 50% or 100% natural raw materials. These pouches are fully or partially compostable and may be for different waste streams.
