Method of packaging manufactured stone
A method of packaging manufactured stones comprises placing two layers of manufactured stones in a vented container and separating the two manufactured stone layers with a separator sheet made from a spun-bond, non-woven fabric having a desired moisture vapor transmission rate.
1 . A method of packaging manufactured stones, comprising:
placing two layers of manufactured stones in a vented container; and
separating said two layers of manufactured stones with a separator sheet made from a spun-bond, non-woven fabric having a moisture vapor transmission rate of at least 100 grams/100 sq in/24 hours as measured by ASTM E-96.
2 . The method of claim 1 including using a polypropylene material for said fabric.
3 . The method of claim 1 , including using a polypropylene material with a weight per unit area of between about 2.1 and about 0.5 ounces/yd 2 for said fabric.
4 . The method of claim 1 , including using a polypropylene material with a weight per unit area of about 0.75 ounces/yd 2 for said fabric.
5 . The method of claim 1 , including using a polyester material for said fabric.
6 . The method of claim 1 , including using a combination of polypropylene material and polyester material for said fabric.
7 . The method of claim 1 , including using a fabric with a tensile MD of at least 58 N as per Edana ERT 20.2-89.
8 . The method of claim 1 , further including providing a series of apertures in said separator sheet.
9 . The method of claim 8 , including using apertures having a diameter of about 0.25 inch.
10 . The method of claim 1 , including providing a double layer separator sheet.
11 . The method of claim 10 , including providing said double layer separator sheet with at least one side seam so as to form a pouch.
12 . The method of claim 1 , including using a patternless fabric with only random surface features.
13 . A package of manufactured stones, comprising:
two layers of manufactured stones positioned in a vented container; and
a separator sheet positioned between the two layers of stones, the sheet comprising a material having a moisture vapor transmission rate of at least 100 grams/100 sq in/24 hours as measured by ASTM E-96.
14 . The package of claim 13 , wherein the separator sheet comprises a spun-bond, non-woven fabric.
15 . The package of claim 14 , wherein the separator sheet is made from a material selected from a polypropylene material, polyester material or a combination thereof.
16 . The package of claim 15 , wherein the sheet is made primarily from a polypropylene material having a weight per unit area of between about 2.1 and about 0.5 ounces/yd 2 .
17 . The package of claim 16 , wherein the polypropylene material has a weight per unit area of about 0.75 ounces/yd 2 .
18 . The package of claim 13 , wherein the separator sheet comprises a fabric with a tensile MD of at least 58 N as per Edana ERT 20.2-89.
19 . The package of claim 13 , further including providing a plurality of apertures in said separator sheet.
20 . The package of claim 13 , wherein the separator sheet comprises a double layer separator sheet with at least one side seam so as to form a pouch.
