An interlayer film for laminated glass according to the present invention has one end, and the other on an opposite side of the one end, the other end has a thickness larger than a thickness of the one end, and when the interlayer film is arranged between two sheets of clear glass conforming to JIS R3202:1996 to obtain a laminated glass X, and a specific measurement of parallel light transmittance is conducted for the laminated glass X obtained, the interlayer film has a gradation part in which a parallel light transmittance continuously reduces from the one end side to the other end side, and an absolute value of a variation rate in the parallel light transmittance is more than 0.3%/mm; a transparent part located closer to the one end side than the gradation part and having a parallel light transmittance of 60% or more; and a dark color part located closer to the other end side than the gradation part and including one or more points A having an absolute value of a variation rate in the parallel light transmittance of 0.3%/mm or less.

According to at least one embodiment of the present disclosure, a multilayer elastic film comprises a core layer, a first outer layer, and a second outer layer. The core layer comprises at least 75 wt % polyolefin elastomer such as an ethylene/alpha-olefin block copolymer or a propylene-based plastomer. The first outer layer and the second outer layer each comprise at least 75 wt % of an ethylene-based copolymer, wherein the ethylene-based copolymer is selected from the group consisting of: (I) greater than 50 wt % of ethylene, from 5 to 16 wt % of an α,β-ethylenically unsaturated C3-C8 carboxylic acid, and optionally, from 0.5 to 10 wt % of an alkyl acrylate; (II) from 86 to 95 wt % of ethylene, and from 5 to 14 wt % of an alkyl acrylate; and (III) combinations thereof.

The invention relates to multilayer polymer structures having at least three layers. These layers include a polar capstock layer other than an acrylic, an olefinic substrate layer, and a tie layer. The tie layer is selected from olefinic acrylate copolymers, a block copolymer of vinyl aromatic monomer with an aliphatic conjugated diene or a derivative thereof, a copolymer of olefin and (meth)acrylic acid partially or fully in the salt form, a high impact polystyrene, and/or a vinyl cyanide-containing compound. Each layer could contain multiple sub-layers. The multilayer structure exhibits excellent structural integrity, excellent surface appearance, high impact strength, high scratch resistance, and excellent resistance to UV rays.

The present disclosure provides resins that can be used as a tie layer in a multilayer structure and to multilayer structures comprising one or more tie layers formed from such resins. In one aspect, a resin for use as a tie layer in a multilayer structure comprises a first composition, wherein the first composition comprises at least one ethylene-based polymer and wherein the first composition comprises a MWCDI value greater than 0.9, and a melt index ratio (I10/I2) that meets the following equation: I10/I2≥7.0−1.2×log (I2), wherein the first composition comprises 1 to 99 weight percent of the resin; and a maleic anhydride grafted polyethylene comprising a maleic anhydride grafted high density polyethylene, a maleic anhydride grafted linear low density polyethylene, a maleic anhydride grafted polyethylene elastomer, or a combination thereof, wherein the maleic anhydride grafted polyethylene comprises 1 to 99 weight percent of the resin.

The present disclosure relates to a recyclable retort package made of one type (mono) material. Specifically disclosed herein is a recyclable retort package that includes an outer layer and an inner layer, wherein the outer layer includes oriented polypropylene material and the inner layer includes polypropylene material.

A multilayer film having at least one barrier layer and at least one outer layer, suitable for medical applications, such as ostomy applications, which is effective as barrier for odors and has sufficient properties with respect to provide a pliable, tear resistant with noise damping film is provided. The multilayer film includes polyolefin elastomers, plasticized PVDC, ethylene vinyl acetate copolymers and additives.

In an embodiment, the invention comprises a wrapper with dead bend characteristics. The wrapper comprises a first polyethylene layer comprising low density polyethylene; a second polyethylene layer affixed to the first layer, wherein the second polyethylene layer comprises high density polyethylene; a first tie layer affixed to the second layer, opposite the first layer; a barrier layer affixed to the tie layer, opposite the second layer; a second tie layer affixed to the barrier layer, opposite the first tie layer; a third polyethylene layer affixed to the second tie layer, opposite the barrier layer, wherein the third polyethylene layer comprises high density polyethylene; and a fourth polyethylene layer affixed to the third polyethylene layer, opposite the second tie layer, wherein the fourth polyethylene layer comprises low density polyethylene. In an embodiment, the tie layers and the barrier layer may be substituted with a cyclic olefin copolymer layer.

An all polyethylene multilayer film structure having alternating layers of (A) a linear low density polyethylene and (B) a high density polyethylene has improved performance properties relative to a film structure in which the (A) and (B) layers are arranged in a block like or random manner.
