Abstract
A blank for a package can include a substrate comprising a recyclable paper, the substrate having a first side and a second side opposite the first side. The blank can include one or more recyclable fluid resistant layers on the first side of the substrate configured to prevent water and/or oxygen from passing through to the substrate. The one or more recyclable fluid resistant layers can be configured to be an outside of the package. The blank can include a recyclable fluid permeable layer disposed on the second side and configured to allow a controlled amount of a fluid transmissibility and/or absorption by or through the fluid permeable layer.
Claims20
A blank for a package comprising:
- a substrate comprising a recyclable paper, the substrate having a first side and a second side opposite the first side;
- one or more recyclable fluid resistant layers on the first side of the substrate configured to prevent water and/or oxygen from passing through to the substrate, the one or more recyclable fluid resistant layers configured to be an outside of the package, wherein the one or more recyclable fluid resistant layers include at least two layers comprising a first layer and a second layer, wherein the first layer includes adhesive and is bonded to the substrate with the adhesive;
- and
- a recyclable fluid permeable layer comprising coating directly disposed on the second side and configured to allow a controlled amount of a fluid transmissibility and/or absorption by or through the fluid permeable layer.
A container for holding a frozen item, comprising:
- a substrate comprising a recyclable paper, the substrate having a first side and a second side opposite the first side;
- one or more recyclable fluid resistant layers on the first side of the substrate configured to prevent water and/or oxygen from passing through to the substrate, the one or more recyclable fluid resistant layers configured to be an outside of the package, wherein the one or more recyclable fluid resistant layers include at least two layers comprising a first layer and a second layer, wherein the first layer includes adhesive and is bonded to the substrate with the adhesive;
- and
- a recyclable fluid permeable layer comprising coating directly disposed on the second side and configured to allow a controlled amount of a fluid transmissibility and/or absorption by or through the fluid permeable layer, wherein the container is configured such that the recyclable fluid permeable layer is an inside surface on which the frozen item sits.
A method for forming a blank, comprising:
- coating a first side of a water absorptive substrate with one or more recyclable water resistant or recyclable water impermeable layers;
- and
- coating a second side of the substrate with one or more recyclable fluid permeable layer having a controlled amount of fluid permeability configured to allow a controlled amount of a fluid transmissibility and/or absorption by or through the fluid permeable layer, wherein the one or more recyclable fluid resistant layers include at least two layers comprising a first layer and a second layer, wherein the first layer includes adhesive and is bonded to the substrate with the adhesive.
