Polyolefin stretch film

Abstract

The present invention discloses a stretch film with improved physical properties and packaging performance that can replace conventional PVC-based stretch films. The stretch film is laminated with two skin layers and a core layer, and the skin layers contain ethylene vinyl acetate (EVA) and an anti-fogging agent, while the core layer contains propylene terpolymer, polyolefin elastomer (POE), and petroleum resin (HCR). This results in good film formability, a breaking elongation of 700% or more, and a tensile strength of 2 kgf / mm. 2 The elastic modulus (Young's modulus) is 8kgf / mm 2 The present invention provides a stretch film having an adhesive strength of 10 N or more, a haze of 2% or less, excellent film physical properties, and excellent packaging properties such as blocking performance, anti-fogging properties, adhesion, and workability.
