Example Embodiment

[0010] The heating bag 1 shown in FIGS. 1 and 2 is composed of a non-woven fabric bag 2 and a molten aluminum thermal agent 3. The non-woven bag 2 may be a double-layer polyester hot-rolled non-woven fabric / polyethylene powder composite material that has been hydrophilically treated. It can also be a hydrophilic treated polyester hot-rolled non-woven fabric / polyethylene powder / polypropylene hot-rolled non-woven fabric composite material. Aluminum liquid thermal agent 3 is a mixture of industrial aluminum powder and alkaline materials, with a particle size in the range of 40 mesh to 200 mesh, and is usually packed in compartments. The edge 4a of the bag and the cross section 4b can be heat sealed by low frequency heat sealing or ultrasonic heat sealing. In order to prevent the bag edge 4a from opening, the four edges can be reinforced by sewing. The storage of the heating bag 1 should be put into the bag 6 and sealed in moisture-proof. When heating and using, as shown in FIG. 3, th...

Abstract

A portable self-heating sack includes heating sack, non-woven fabric sack and aluminum-water heating agent. The aluminum-water heating agent is comprised by aluminum, accelerant containing alkali material, depressant containing soluble oil material, and is completely powdered, in this manner, heat generation speed can be accelerated and high temperature can be obtained. The heating agent is packed in hydrophilic double-layer composite non-woven fabric grid, so that external surfaces of the heating sack and food sack is undefiled during the affusion activating procedure and a procedure of heat generation for heating food. The self-heating sack making in this manner has advantages of low cost, easement for use and carrying, quick heating, high temperature.

Description

technical field [0001] The invention relates to a packaging bag, in particular to a self-heating packaging bag. Background technique [0002] In the food field, cooking utensils are usually used for heating edible food, which is extremely inconvenient for the majority of office workers, students, car drivers, especially tourists and field workers such as soldiers, etc. to eat outdoors, so a special heating device is made to allow It is a problem that people have been paying close attention to that people can have hot meals and hot dishes.
