RESEALABLE FOOD BAGS AND METHOD THEREOF
Embodiments of the present invention generally relate to resealable food bags utilizing an adhesive compound, and a method thereof. In one embodiment of the present invention, a resealable food stuff bag comprises a food stuff bag with an interior and an exterior, and an adhesive tape applied to the interior of the food bag, wherein the adhesive tape comprises a carrier with a first side and a second side, a layer of food-grade permanent adhesive applied to the first side of the carrier, and a layer of food-grade removable adhesive applied to the second side of the carrier.
1 . An adhesive tape, comprising:
a carrier with a first side and a second side;
a layer of food-grade permanent adhesive applied to the first side of the carrier; and
a layer of food-grade removable adhesive applied to the second side of the carrier.
2 . The adhesive tape of claim 1 , wherein the adhesive tape has a width of at least one quarter of an inch.
3 . The adhesive tape of claim 1 , wherein the carrier has a thickness of about 0.5 mils.
4 . The adhesive tape of claim 1 , wherein the carrier comprises at least one of polyester, polyethylene, polyethylene-terephthalate, polypropylene, polyvinylidine chloride, polyvinylchloride, or polyolefin.
5 . The adhesive tape of claim 1 , wherein the food-grade permanent adhesive comprises at least a rubber or an acrylic food-grade adhesive compound.
6 . The adhesive tape of claim 1 , wherein the food-grade removable adhesive comprises a food-grade pressure sensitive adhesive compound.
7 . The adhesive tape of claim 1 , wherein the food-grade removable adhesive comprises a food-grade acrylic based adhesive compound.
8 . The adhesive tape of claim 1 , wherein the food-grade removable adhesive further comprises a tackifying resin.
9 . The adhesive tape of claim 8 , wherein the food-grade removable adhesive further comprises about 0.0 percent to about 15.0 percent by weight of the tackifying resin.
10 . The adhesive tape of claim 8 , wherein the food-grade removable adhesive further comprises about 2.5 percent by weight of the tackifying resin.
11 . The adhesive tape of claim 8 , wherein the tackifying resin is an aliphatic resin.
12 . The adhesive tape of claim 8 , wherein the tackifying resin is a rosin ester resin
13 . The adhesive tape of claim 1 , further comprising a release liner applied to an exposed side of the layer of food-grade permanent adhesive compound.
14 . The adhesive tape of claim 13 , wherein the release liner comprises at least one of polymeric film liners, paper liners, or board liners.
15 . A method of forming an adhesive tape comprising:
providing a carrier;
applying a layer of food-grade permanent adhesive to a first side of the carrier; and
applying the layer of food-grade removable adhesive to the second side of the carrier.
16 . The method of claim 15 , further comprising applying the layer of food-grade permanent adhesive by coating the first side the carrier between about 16 pounds and about 40 pounds per ream.
17 . The method of claim 16 , further comprising applying the layer of food-grade permanent adhesive by coating the first side the carrier at about 27 pounds per ream.
18 . The method of claim 15 , further comprising applying the layer of food-grade removable adhesive by coating the second side the carrier between about 16 pounds and about 40 pounds per ream.
19 . The method of claim 18 , further comprising applying the layer of food-grade removable adhesive by coating the second side the carrier at about 27 pounds per ream.
20 . The method of claim 15 , further comprising processing the carrier such that the layer of food-grade removable adhesive compound is adhered by heat lamination to the carrier.
21 . The method of claim 15 , further comprising corona treating at least a side of the carrier.
22 . The method of claim 15 , further comprising drying the layer of food-grade removable adhesive at a temperature of about 225 degrees Fahrenheit.
23 . The method of claim 22 , further comprising drying the layer of food-grade removable adhesive for a time period of about two minutes.
24 . The method of claim 15 , further comprising:
applying the layer of food-grade permanent adhesive to a first side of a release liner material; and
drying the layer of food-grade permanent adhesive prior to applying the layer of food-grade permanent adhesive to the first side of the carrier.
25 . The adhesive tape of claim 24 , further comprising applying the layer of food-grade permanent adhesive by coating the first side of the release liner material at about 27 pounds per ream.
26 . The adhesive tape of claim 24 , further comprising drying the layer of food-grade permanent adhesive at a temperature of about 190 degrees Fahrenheit.
27 . The adhesive tape of claim 26 , further comprising drying the layer of food-grade permanent adhesive for a time period of about two minutes.
28 . A resealable food bag comprising:
a food stuff bag with an interior layer and an exterior layer; and
an adhesive tape applied to the interior layer of the food bag, wherein the adhesive tape comprises:
a carrier with a first side and a second side;
a layer of food-grade permanent adhesive applied to the first side of the carrier; and
a layer of food-grade removable adhesive applied to the second side of the carrier.
29 . The resealable food bag of claim 28 , wherein the interior layer of the food bag comprises polypropylene.
30 . The resealable food bag of claim 29 , wherein the interior layer is at least partially metallized.
