Packaging prefinished fiber cement products
View Patent ↗Protected prefinished fiber cement products are manufactured by applying a protective layer on the finished surface of a fiber cement product. The protective layer protects the finish layer of the prefinished fiber cement product during handling, storage, and transport. Removing the protective layer leaves no adhesive residue on the finish layer, does not damage the finish layer, and does not substantially tear the protective layer. Protected prefinished fiber cement products are typically stacked on pallets for storage and transport. Optionally, spacers may be placed between the stacked protected prefinished fiber cement products.
1. An assembly of protected prefinished fiber cement products comprising a plurality of protected prefinished fiber cement articles arranged in a stack, wherein a protected prefinished fiber cement product comprises:
a fiber cement product, a non-adhesive finish layer applied to the fiber cement product, and a removable multilayer protective layer consisting essentially of a separate polymer film and a separate adhesive layer, said adhesive layer of said multilayer protective layer adhered to the non-adhesive finish layer, wherein the adhesive layer is selected with predetermined adhesive properties to work in concert with the thickness and tensile strength of the protective layer such that the adhesive bonds weakly to the fiber cement product to allow the polymer film and the adhesive layer to be removed from the fiber cement product at the same time without tearing or leaving a residue on the non-adhesive finish layer, wherein the thickness of the protective layer is from about 0.0001 inch to about 0.08 inch and the tensile strength of the protective layer is from about 1200 to 4767 psi;
the multilayer protective layer protects the finish layer from damage in storage, transport and handling,
removing the multilayer protective layer leaves no residue on the non-adhesive finish layer and does not damage the non-adhesive finish layer, and
the multilayer protective layer resists tearing on removal.
2. The protected prefinished fiber cement product of claim 1 , wherein the protective layer is from about 0.0003 inch to about 0.03 inch thick.
3. The protected prefinished fiber cement product of claim 2 , wherein the protective layer is from about 0.001 inch to about 0.01 inch thick.
4. The assembly of claim 1 , wherein the protected prefinished fiber cement products are banded together.
5. The assembly of claim 1 , wherein the protected prefinished fiber cement products are stacked on a pallet.
