<p>The bag (101) has a wall (104) with a calendered non-woven fabric layer formed as a melt-spun microfiber non-woven fabric layer, where the fabric layer is calendered using thermal energy or ultrasonic waves. The fabric layer has a surface area of 120 grams per square meter and maximum force of more than 60 Newton in a machining direction and more than 50 Newton in a transverse direction. Thickness of the fabric layer is in the range of 0.4 to 0.8 mm, where the fabric layer is made of polymer, polypropylene and biologically degradable plastic e.g. polylactide.</p> |
