They are used for waste disposal, especially for: leftovers in households and industry, medical institutions etc. They are produced in different sizes, volumes and colours. They can be produced with or without ties. Bags with ties are more economic for use (it makes them bigger), and more practical for disposal (the tie can be used as a handle). Bags are wrapped on a roll with perforation for ripping. Bags are produced from original and recycled materials which makes them eco friendly.
