Patent number: 10766236Abstract: In order to improve the sealing properties and the sliding properties of a sealing film, surface structures are provided on a first side of the sealing film, the greatest thickness of the sealing film being at least 10% greater than the smallest thickness of the sealing film and the greatest lateral extension of the surface structures being less than 500 ?m. A slip additive is added to the sealing film in a maximum quantity that results in an S-value of less than 10,000, preferably less than 5,000, in order to achieve a COF relative to steel of dynamically less than 0.3, preferably less than 0.27, and statically less than 0.35, preferably less than 0.3, with the side comprising the surface structures, irrespective of an addition of an antiblock additive to the sealing film.Type: GrantFiled: March 14, 2016Date of Patent: September 8, 2020Assignee: Constantia Pirk GmbH & Co.

Patent number: 10751979Abstract: 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 ?m 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.Type: GrantFiled: July 8, 2016Date of Patent: August 25, 2020Assignee: Constantia Pirk GmbH & Co.
