[0217] The layer configurations are provided below in Table 2. Each multilayer film structure is formed with a first layer having a volume that is 20 volume % of the multilayer film, a second layer having a volume that is 60 volume % of the multilayer film, and a third layer having a volume that is 20 volume % of the multilayer film. The first layer is a skin layer that is a sealant layer. The second layer is a core layer. The third layer is a skin layer. The multilayer film has the following structure: first layer/second layer/third layer. The first layer is in direct contact with the second layer, and the second layer is in direct contact with the third layer. In Table 2, CS refers to Comparative Sample.

[0218] The PDMS is included in the first layer as part of a masterbatch (MB25-502) in which the PDMS is dispersed in a LDPE A matrix. Table 2 provides the individual amounts of the PDMS and the LDPE A matrix included in the first layer. For example, the first layer of Example 1 includes 0.375 wt % of the PDMS from MB25-502 (which has a Mn of 48,400 g/mol, as provided in Table 1A) and 1.125 wt % of the LDPE A from MB25-502, based on the total weight of the first layer. Thus, the first layer of Example 1 contains a total amount of 1.500 wt % MB25-502, based on the total weight of the first layer.

[0219] The talc antiblock agent is also included in the first layer as part of a masterbatch (ME 50024) in which the talc is dispersed in a LDPE B matrix. Table 2 provides the individual amounts of the talc and the LDPE B matrix included in the first layer. For example, the first layer of Example 1 includes 0.400 wt % of the talc from ME 50024 and 0.225 wt % of the LDPE B from ME 50024, based on the total weight of the first layer. Thus, the first layer of Example 1 contains a total amount of 0.625 wt % MB25-502, based on the total weight of the first layer.

[0220] The multilayer film samples are tested for COF. The results are provided below in Table 2.

[0221] As shown, comparative sample films with a first layer containing (A) an ethylene-based polymer (AFFINITY PL 1880G and LDPE) and (C) from 0.1-5 wt % PDMS, and no carboxylic-functionalized ethylene-based polymer (CS 3, CS 5, CS 6) exhibit a high COF (0.36-0.64).

[0222] Applicant surprisingly found that a film with a first layer containing (A) an ethylene-based polymer (AFFINITY PL 1880G and LDPE); (B) carboxylic-functionalized ethylene-based polymer (AMPLIFY TY 1353, which is a MAH-g-LLDPE); and (C) from 0.1-5 wt % PDMS, based on the total weight of the first layer (Ex. 1, Ex. 2, Ex. 4), advantageously exhibits a coefficient of friction (COF) of less than 0.36, and further less than 0.35.
