Embodiment

[0118] It is to be understood that while the invention has been described in connection with specific embodiments thereof, the foregoing description is intended to illustrate rather than limit the scope of the invention. Other aspects, advantages and modifications will be apparent to those skilled in the art to which the invention pertains.

[0119] Therefore, the following examples are presented to provide complete disclosure and description to those skilled in the art, and are not intended to limit the scope of the invention which the present invention is regarded as.

[0120] 218 polymer films comprising the Polymer A composition were produced. The tear was measured for each MD . figure 1 is the tear of polymer A as a function of strain rate MD diagram.

[0121] figure 1 The data and corresponding physical properties of Polymer A (specifically bulk density, melt flow rate and flow rate ratio) and blown film extrusion conditions (specifically melt temperature, strain ra...

Abstract

Methods for forming polyolefin films using a model including a multivariate adaptive regression splines (MARS)-derived algorithm are provided. Related computing devices are also provided.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of US Serial No. 62 / 674877, filed May 22, 2018, and EP18177657.6, filed June 14, 2018, the disclosures of which are hereby incorporated by reference in their entirety. [0003] field of invention [0004] The present disclosure relates to a method of forming films, primarily films made of polyolefin polymers, using a model (A) to estimate the polymer film based on the physical properties of the polymer and blown film extrusion conditions MD tear, or (B) estimating the necessary polymer physical properties and blown film extrusion conditions necessary to achieve a polymer film with the desired MD tear. The present disclosure also relates to computing devices using such methods. [0005] Background of the invention [0006] Blown film technology is a common way of manufacturing polyethylene films. Such films can be used in the manufacture of bags, plastic wrap films, agricultural films...
