Embodiment

[0067] Various multilayer films according to the inventive subject matter were prepared. Each multilayer film includes a single core layer disposed between two skin layers. In some embodiments, the composition of the skin layers is the same, while in other embodiments, the composition of the skin layers is different. The weight ratio of the core layer is 70%, and the weight ratio of each skin layer is 15%. Table 1 summarizes the multilayer films with skin-core-skin arrangement and the composition of each layer.

[0074] Given that marked articles, including marked bottles, are likely to be conveyed on metal rails on high speed production lines or metal rails lined with high density polyethylene, enhanced abrasion resistance is desirable. Wall friction encountered by marked articles can lead to surface defects, including scratches or marred markings, which are aes...

Abstract

Compositions well suited for forming machine direction oriented (MDO) films are described. Multilayer films comprising one or more layers of compositions and / or films are also described. Additionally, label assemblies utilizing multilayer films, marked substrates, and related methods are described. Various versions of multilayer films are described, including films having an inner core layer and at least two skin layers. Certain multilayer films having a polyethylene-enriched core are also described.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Provisional Patent Application No. 62 / 006,447, filed June 2, 2014, which is hereby incorporated by reference in its entirety. [0003] Background of the invention [0004] The present subject matter relates to machine direction oriented (MDO) films and compositions for forming such films. The subject-matter of the invention also relates to the use of MDO films in decoration technology, labels and labeling applications coated or uncoated with adhesive on the film, as well as in the case of direct application of the adhesive to the substrate and indirectly to the film. In particular, the present subject matter relates to multilayer films having an inner core layer with a higher polyethylene content but unexpectedly retaining the lower polyethylene content of MDO films It has excellent transparency and enhanced wear resistance. At the same time, the present invention also considers...
