Abstract
The present teaching describes a recyclable polyethylene film of at least 80% polyethylene material and max. 20% compatible polyolefin material. The polyethylene film is less than 40 μm and has a central layer of linear low-density polyethylene (LLDPE) and/or metallocene linear low-density polyethylene (mLLDPE) and two outer layers made of high-density polyethylene (HDPE) and bonded to the central layer and surrounding a central layer. The HDPE content of the polyethylene film constitutes at least 60 vol %, preferably at least 70 vol %, especially preferably at least 80 vol. The two outer layers together are at least three times as thick as the central layer, preferably at least four times as thick. The polyethylene film is stretched in at least one direction.
