Abstract
Protection barriers, such as floor protection barriers, and methods for making and using same. The protection barrier can include a base sheet and an energy absorbing layer. The base sheet can have two or more paperboard layers and one or more sizing layers. A first paperboard layer can form a first surface of the base sheet, a second paperboard layer can form a second surface of the base sheet, and the one or more sizing layers can be disposed between the first and second paperboard layers. The energy absorbing layer can be secured to the second paperboard layer.
Claims20
A protection barrier, comprising:
- a base sheet comprising a first paperboard layer, a second paperboard layer, and one or more sizing layers, wherein the first paperboard layer forms a first surface of the base sheet, the second paperboard layer forms a second surface of the base sheet, and the one or more sizing layers are disposed between the first and second paperboard layers;
- and
- an energy absorbing layer secured to the second paperboard layer, wherein:
- the protection barrier has a water vapor transmission rate of about 5 g/645.2 cm2/24 hr to about 150 g/645.2 cm2/24 hr, as measured according to ASTM E96M-14, Procedure A,
- the sizing layer has an average oil and grease resistance value of about 6 or greater, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard, and
- the protection barrier has an oil and grease resistance flotation value of about 3 hours or greater, as measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415.
A protection barrier, comprising:
- a base sheet comprising one or more sizing layers disposed between two or more paperboard layers;
- and
- an energy absorbing layer secured to the base sheet, wherein:
- the protection barrier has a water vapor transmission rate of about 5 g/645.2 cm2/24 hr to about 150 g/645.2 cm2/24 hr, as measured according to ASTM E96M-14, Procedure A,
- the sizing layer has an average oil and grease resistance value of about 6 to 12, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard,
- the protection barrier has an oil and grease resistance flotation value of about 3 hours to about 24, as measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415,
- the protection barrier has a thickness of about 0.2 mm to about 10 mm,
- the protection barrier has a width of about 0.25 m to about 4 m, and
- the protection barrier has a basis weight of about 300 g/m2 to about 800 g/m2.
A method for making a protection barrier, comprising:
- forming a base sheet comprising a first paperboard layer, a second paperboard layer, and one or more sizing layers, wherein the first paperboard layer forms a first surface of the base sheet, the second paperboard layer forms a second surface of the base sheet, and the one or more sizing layers are disposed between the first and second paperboard layers;
- and
- securing an energy absorbing layer to the second paperboard layer, wherein:
- the protection barrier has a water vapor transmission rate of about 5 g/645.2 cm2/24 hr to about 150 g/645.2 cm2/24 hr, as measured according to ASTM E96M-14, Procedure A,
- the sizing layer has an average oil and grease resistance value of about 6 or greater, as measured according to TAPPI T-559 standard test for Grease Resistance for Paper and Paperboard, and
- the protection barrier has an oil and grease resistance flotation value of about 3 hours or greater, as measured according to the Georgia-Pacific Flotation Paper Saturation Test STP-415.
