TWO-SIDED NONWOVEN ABSORBENT FOOD PAD
An absorbent food pad is disclosed having nonwoven top and bottom layers with an equal percentage surfactant by weight. The pad provides liquid strikethrough and absorbency without drying a food product, regardless of orientation of the pad when placed on a food tray.
1 . An absorbent food pad comprising:
a top layer comprising a first nonwoven;
a bottom layer opposite said top layer comprising a second nonwoven;
a surfactant present in said first nonwoven and said second nonwoven in equal percentage by weight, based on a basis weight of said first nonwoven and said second nonwoven; and
an absorbent layer disposed between said top layer and said bottom layer.
2 . The absorbent food pad according to claim 1 , further comprising an active agent present in said absorbent layer.
3 . The absorbent food pad according to claim 2 , wherein said active agent is an antimicrobial, atmosphere modification system, or combination thereof.
4 . The absorbent food pad according to claim 1 , wherein said first nonwoven and said second nonwoven each have said basis weight between about 15 grams per square meter (GSM) to about 35 GSM.
5 . The absorbent food pad according to claim 1 , wherein said first nonwoven and said second nonwoven are selected from the group consisting of polypropylene, polyethylene, polyester, and any combinations thereof.
6 . The absorbent food pad according to claim 5 , wherein said first nonwoven and said second nonwoven are spunbond polypropylene.
7 . The absorbent food pad according to claim 1 , wherein said surfactant is in said first nonwoven and in said second nonwoven in an amount between about 0.30% to about 0.85% by weight, based on said basis weight of said first nonwoven and said second nonwoven.
8 . The absorbent food pad according to claim 7 , wherein said surfactant is in said first nonwoven and said second nonwoven in said amount between about 0.57% to about 0.84% by weight, based on said basis weight of said first nonwoven and said second nonwoven.
9 . The absorbent food pad according to claim 1 , wherein said basis weight of said first nonwoven and said second nonwoven are 20 GSM, and said amount of said surfactant is 0.57% by weight, based on said basis weight of said first nonwoven and said second nonwoven.
10 . The absorbent food pad according to claim 9 , wherein said amount of said surfactant and said basis weight of said first nonwoven and said second nonwoven provide a strikethrough time that is less than about 9.5 seconds.
11 . The absorbent food pad according to claim 10 , wherein said amount of said surfactant and said basis weight of said first nonwoven and said second nonwoven provide a strikethrough time that is less than or equal to about 9.0 seconds.
12 . The absorbent food pad according to claim 1 , wherein said surfactant is selected from the group consisting of polyethylene glycol, polypropylene glycol, polysorbate, sulfosuccinate, fatty amine oxide, linear alcohol ethoxylate, alkanolamide, alkylphenol ethoxylate, block co-polymer of ethylene oxide and propylene oxide, alkylphenol ethoxylate, alkylphenol polyethylene glycol ether, and any salts, and any combinations thereof.
13 . The absorbent food pad according to claim 1 , wherein said first nonwoven and said second nonwoven have a different basis weight.
14 . The absorbent food pad according to claim 1 , wherein said top layer is a food-contacting layer.
15 . The absorbent food pad according to claim 1 , wherein said bottom layer is a food-contacting layer.
16 . The absorbent food pad according to claim 1 , further comprising a pocket formed between said top layer and said bottom layer.
17 . The absorbent food pad according to claim 16 , wherein said pocket holds an active agent prior to activation.
18 . The absorbent food pad according to claim 1 , wherein said top layer and said bottom layer directly contact each other along their entire peripheries, thereby enclosing said absorbent layer.
19 . A case-ready food package comprising:
a food tray;
an absorbent food pad positioned on said food tray, comprising:
a top layer comprising a first nonwoven;
a bottom layer opposite said top layer comprising a second nonwoven;
a surfactant present in said first nonwoven and said second nonwoven in equal percentage by weight, based on said basis weight of said first nonwoven and said second nonwoven;
an absorbent layer disposed between said top layer and said bottom layer,
wherein said top layer and said bottom layer directly contact each other along their entire peripheries, thereby enclosing said absorbent layer; and
a food product positioned on said absorbent food pad; and
a lid placed over the food product and said food tray, and adhered to said food tray,
wherein said food tray and said lid completely enclose said absorbent food pad and the food product.
20 . A method of using an absorbent food pad comprising:
placing said absorbent food pad on a food tray, wherein said absorbent food pad comprises:
a top layer comprising a first nonwoven;
a bottom layer opposite said top layer comprising a second nonwoven;
a surfactant present in said first nonwoven and said second nonwoven in equal percentage by weight, based on said basis weight of said first nonwoven and said second nonwoven; and
an absorbent layer disposed between said top layer and said bottom layer, and
wherein said absorbent food pad can be positioned in said food tray with either said top layer or said bottom layer in contact with a food product without drying said food product.
