Embodiment Construction

[0027] Before several exemplary embodiments of the invention are described, it is to be understood that the invention is not limited to the details of construction or process steps set forth in the following description. The invention is capable of other embodiments and of being practiced or carried out in various ways.

[0028] The present invention relates to a multilayer polymer film comprising only olefin-based polymers that provide performance and low cost. The multilayer polymeric film of the present invention provides a recyclable and durable film due to the use of one or more layers of polypropylene, an anhydride-modified polyethylene-based tie layer and a polyethylene (PE) seal layer. One or more embodiments of the invention relate to various applications of the polymeric films described herein, including but not limited to vertical or horizontal fill-seal packaging, pouch films, flow packaging; and in flexible blister packaging ( Top and bottom web polymer films suc...

Abstract

The present invention provides a polymeric film and, and more particularly provides a multi-layer polymeric film including one or more structural layers of homogenous polypropylene, one or more structural layers of random copolymer polypropylene, one or more anhydride modified polyethylene based tie layers, and one or more linear low density polyethylene (LLDPE) blend sealant layers having a primary LLDPE component, a secondary LLDPE component and an optional LDPE additive component.

Description

technical field [0001] Aspects of the present invention relate to polymer films, and more particularly to a multilayer polymer film comprising one or more structural layers of homopolypropylene, one or more structural layers of random copolymer polypropylene, and a or more anhydride-modified polyethylene-based tie layers, and one or more linear low-density polyethylene (LLDPE) having a primary LLDPE component, an optional secondary LLDPE component, and an optional LDPE additive component Blend seal coat. Background technique [0002] Many polymer films currently used in industry are still not recyclable. Due to increased environmental awareness and desire to reduce environmental impact, there is still a need for recyclable polypropylene / polyethylene films with customizable physical and sealing properties at thin thicknesses such as good formability, toughness and impact strength . Furthermore, despite advances in polyethylene peelable sealing technology, poor sealing perf...
