Silo bags with non-uniform thickness and methods of producing

A method of using a multilayer silo bag, wherein filling the multilayer silo bag causes the thickness of the first region to decrease by less than 15%, wherein the multilayer silo bag comprises

• a tube comprising at least two layers, the tube having a first open end, a second open end, and a first region disposed between the first and second end and a second region disposed between the first and second end,
• wherein each of the at least two layers comprises an ethylene/alpha-olefin interpolymer having a density of 0.90 g/cc to 0.965 g/cc when measured according to ASTM D792 and a melt index (I2) of 0.1 to 6.0 g/10 minutes when measured according to ASTM D1238, a low density ethylene-based polymer having a density of 0.917 g/cc to 0.935 g/cc and melt index (I2) of 0.1 to 2.0 g/10 minutes, or combinations thereof;
• wherein the first region has a thickness of at least 10% greater than a thickness of the second region;
• wherein the first region has a surface area that is at least 65% of an overall surface area of the multilayer silo bag;
• and
• wherein the tube has an overall thickness of 50 micrometers (μm) to 350 μm.

A method of manufacturing a multilayer silo bag, the method comprising:

• forming a multilayer layer blown film bubble, wherein the multilayer layer blown film bubble comprises at least two layers,
• wherein each of the at least two layers comprises an ethylene/alpha-olefin interpolymer having a density of 0.90 g/cc to 0.965 g/cc and a melt index (I2) of 0.1 to 6.0 g/10 minutes, a low density ethylene-based polymer having a density of 0.917 g/cc to 0.935 g/cc and melt index (I2) of 0.1 to 2.0 g/10 minutes, or combinations thereof;
• cutting the multilayer blown film bubble to form a multilayer silo bag, the multilayer silo bag comprising a tube having a first open end, a second open end, a first region, and a second region
• wherein the first region has a thickness of at least 10% greater than a thickness of the second region;
• wherein the first region has a surface area that is 65% of an overall surface area of the multilayer silo bag;
• and
• wherein the tube has an overall thickness of 50 μm to 350 μm.
