Abstract: A multilayer film (10) having excellent mechanical strength and transparency comprise a core layer (12), at least two skin layers, and at least two sub-skin layers disposed between the core layer (12) and the two skin layers. The core layer (12) comprises at least 60 wt. % linear low density polyethylene (LLDPE). The sub-skin layers comprise at least 60 wt. % low density polyethylene (LDPE). The skin layers comprise at least 80 wt. % of LLDPE wherein the LLDPE comprises C6 LLDPE, C8 LLDPE, or combinations thereof, and each skin layer has a thickness of less than 25% of the overall thickness of the multilayer film (10). The multilayer film (10) comprises at least 0.1 wt. % ultraviolet stabilizer.
