Bica plastic bags for waste sorting at work. These plastic bags are suitable for mixed waste. Heavy and unmanageable waste should be placed in plastic bags with a high My (thickness). Combine the colors for different types of waste. When buying waste bags, we always recommend that the bag has a capacity of 5-10 ltr. larger than the container in which the bag must fit in. These plastic bags fit perfectly into inner bins with a capacity of 20 ltr.
