[0092] Film polymeric component - Example

[0093] In the following examples, various combinations described, and such a thin layer of polymer coating a thin layer of polymer coating. A thin layer of polymer coating comprising one of the following types corresponding to one or more polymer coatings.

[0094] Low-density polyethylene A (LDPE A) represents a commercially available low density polyethylene resin. LDPE A melt index was 8.2g / 10min and a peak melting temperature was 106 ℃. LDPE A minor does not have a melting temperature peak of 110 deg.] C and between 120 ℃. In other applications, LDPE as desired for coating applications where good organoleptic properties on A conventional vapor.

[0095] Low-density polyethylene B (LDPE B) shows another commercially available low density polyethylene coating. The melt index LDPE B was 5.0g / 10min and a peak melting temperature was 105 ℃. In other applications, LDPE B for low-speed extrusion coating, and its low necking property con...

Abstract

Polymeric coating compositions and articles coated with the polymeric coating compositions are provided. The polymeric coating compositions may include ethylene-based polymers that exhibit desirable melt properties and molecular weight distributions. The polymeric coating compositions can provide thin coatings on articles while still providing beneficial properties, such as seal strength.

Description

[0001] Cross-reference related application [0002] The benefits of the series No. 62 / 646952 submitted on March 23, 2018, which are hereby incorporated by reference in its entirety. [0003] Inventive field [0004] The polymer coating composition and article coated thereof are provided. [0005] Inventory background [0006] The polymer coating composition can be used to coat the various substrates to impart certain properties of the articles produced by it, such as imparting moisture gas protection when accommodating food or beverages. In various applications, such as disposable cups, cutlery and industrial packaging, no thick polymer coatings are required. However, from the viewpoint of processing / manufacturing, conventional selection of the polymer coating composition cannot provide a thin coating in an efficient manner. [0007] U.S. Patent No. 6,565,34 discloses a heat-insulating paper cup having improved sealing. The main body element of the cup is coated with a foamed low ...
