Problems solved by technology

[0003] The heat generating components of the heating pack basically contain a variety of metal powders such as iron powder, aluminum powder, magnesium powder, and calcium oxide, etc., which will produce an exothermic chemical reaction when exposed to water. The package also contains some components (catalysts) that may produce harmful gases, which will produce some peculiar smell when used, and are easy to pollute the environment

Embodiment Construction

[0010] Combine below figure 1 The technical scheme of the present invention is further described.

[0011] A packaging film for heating packs, which sequentially includes a first non-woven fabric base layer 1, a nanometer non-woven fabric purification layer 2, a second non-woven fabric base layer 3, an activated carbon non-woven fabric layer 4 and a third non-woven fabric layer from inside to outside Grassroots 5.

[0012] Antioxidant is smeared on the purification layer 2 of nanometer non-woven fabric. Most of the antioxidants are hydroxyphenols, naphthols and benzene sulfinates, which have certain reducing properties, can capture and digest the oxygen penetrating into the packaging film, and prevent the metal powder in the heating core from being oxidized.

[0013] Apparently, the above-mentioned embodiments of the present invention are only examples for illustrating the present invention, rather than limiting the implementation of the present invention. For those of ordi...

Abstract

A heating bag package film includes a first non-woven fabric base layer, a nano-non-woven fabric purification layer, a second non-woven fabric base layer, an activated carbon non-woven fabric layer and a third non-woven fabric base layer in order from the inside to the outside. The packaging film can prevent a heating core from getting wet, protects the user's health, and avoids environmental pollution.

Description

technical field [0001] The invention relates to the field of heating packs, in particular to a packaging film for heating packs. Background technique [0002] As people's pace of life accelerates, many people are busy with work and have no time to cook, or they don't want to cook at home alone during holidays. At this time, instant food with efficient heating packs can bring us convenience and speed; and now Many people like outdoor camping and hiking, and some even stay overnight in deep mountains and old forests. In virgin forests, there is no power supply and open flames are strictly prohibited. At this time, it is a very happy thing to be able to eat a steaming meal outdoors far away from home , These heating instant foods do not need power supply, no open flame, they can automatically heat up just by adding water, and can serve steaming hot and delicious food to people. [0003] The heat generating components of the heating pack basically contain a variety of metal pow...
