Pressure-sensitive-adhesive release film for oriented HDPE

A polyethylene film comprising:

• a core layer consists of low-density polyethylene, at least 85 wt. % high-density polyethylene, and, optionally, additives;
• a first tie layer on a first side of the core layer consisting essentially of:
• (i) at least about 50 wt. % high-density polyethylene;
• and (ii) from 5 wt. % through 40 wt. % of each of:
• (a) an olefin-block copolymer;
• and (b) low-density polyethylene polymer and/or ethylene-vinyl acetate polymer;
• a second tie layer on a second side of the core layer consisting essentially of:
• (i) at least about 50 wt. % high-density polyethylene;
• and (ii) from 5 wt. % through 40 wt. % of each of:
• (a) an olefin-block copolymer;
• and (b) low-density polyethylene polymer and/or ethylene-vinyl acetate polymer;
• and
• a first skin layer on the first tie layer, wherein the first skin layer is an outer layer and comprises a polyethylene-based polymer, silicone, and antiblock agent,
• wherein the polyethylene film is oriented and coextruded,
• wherein the polyethylene film has a release force capable of excluding a siliconized release liner when pressure-sensitive adhered to a face stock.
