Abstract
Disclosed herein are various embodiments of a protective packaging system suitable for use with a prefinished building article. The protective packaging system generally is designed to reduce shrink back of the flexible substrate after tension is applied. The protective packaging system generally comprises at least one outer layer, at least one core layer and at least one adhesive layer. One or more layers of the protective packaging system may include a roughening agent such that the flexible substrate will not “gloss” or burnish a coating on a prefinished building article.
Claims20
A protective packaging system for providing temporary protection of a top coating on a prefinished building article, comprising:
- an outer layer, said outer layer comprising 25 to 40% by weight of a low density polyethylene (LDPE) and 60 to 75% by weight of a high density polyethylene, wherein the LDPE and the high density polyethylene are present in the outer layer in a mass ratio of about 1:3 to about 3:1;
- an adhesive layer, said adhesive layer comprising ethylene methacrylate copolymer with a methyl acrylate co-monomer content of about 24% or less, acid modified ethylene acrylate terpolymer, an ethylene acrylic acid copolymer comprising 15-40% acid co-monomer, and a first roughening agent, wherein the first roughening agent comprises inorganic particulates dispersed in a polyethylene resin mixture in a manner such that at least some of the inorganic particulates protrude from the adhesive layer;
- and
- a core layer disposed between the outer layer and the adhesive layer, wherein the core layer comprises a linear low density polyethylene, a low density polyethylene, and a dispersed second roughening agent.
A coated fiber cement building article having a surface in contact with a multilayer film, wherein the multilayer film comprises:
- an outer layer comprising a mixture of a low density polyethylene (LDPE) and a high density polyethylene;
- an adhesive layer disposed on the surface of the fiber cement article, said adhesive layer comprising ethylene methacrylate copolymer with a methyl acrylate co-monomer content of about 24% or less, acid modified ethylene acrylate terpolymer, an ethylene acrylic acid copolymer comprising 15-40% acid co-monomer, and a first roughening agent, wherein the first roughening agent comprises inorganic particulates dispersed in a polyethylene resin mixture in a manner such that at least some of the inorganic particulates protrude from the adhesive layer;
- and
- a core layer disposed between the outer layer and the adhesive layer, wherein the core layer comprises a low density polyethylene and a dispersed second roughening agent.
