The hard stiff breathable film layer is arranged on the outer side of the heating layer, the hard stiff breathable film layer supports and protects the warm pasting unit, prevents damage due to scratching, and the low weight breathable film layer is arranged on the inner side of the heating layer, the low weight breathable film layer is soft, can be closely attached to flat and non-flat parts, and is beneficial to improving the adhesion of the skin pasting part.

[0009] In the utility model, the hard stiff breathable film layer is polyethylene breathable film or polypropylene breathable film or polylactic acid breathable film.

[0010] In the utility model, the low weight breathable film layer is polyethylene breathable film or polypropylene breathable film or polylactic acid breathable film.

[0011] In the utility model, the hard stiff breathable film layer has a weight of 25g / m 2 2, and a breathability of 3000g / (m 2 ·24h), preferably a weight of 30-40g / m 2 .

[0012] In the utility model, the low weight breathable film layer has a weight of 13-15g / m 2 2, and a breathability of 3000g / (m 2 ·24h).

[0013] In the utility model, the four peripheral edges of the hard stiff breathable film layer and the four peripheral edges of the low weight breathable film layer are heat sealed together to close the heating layer.

[0014] In the utility model, the packaging bag is separated by a tape bag roll, and the heat sealing connection part is arranged between adjacent packaging bags.

[0015] By adopting the technical scheme, the warm pasting structure has the advantages of strong breathability, good heating effect, firm contact with the skin and comfortable contact. BRIEF DESCRIPTION OF DRAWINGS

[0016] The utility model will be further explained in detail in combination with the drawings and specific embodiments:

[0017] Figure 1 It is the structure section view of the utility model. DETAILED DESCRIPTION

[0018] As Figure 1 shown, the warm patch structure of the utility model, including the packaging bag 100, the warm patch unit 200 of being packed in the packaging bag 100.

[0019] The warm patch unit 200 is in turn from top to bottom from stiff breathable film layer 201, heating layer 202, low grammage breathable film layer 203, viscose layer 204 and release paper layer 205.

[0020] Among them, stiff breathable film layer 201 is polyethylene breathable film or polypropylene breathable film or polylactic acid breathable film breathable film. The grammage is ≥25g / m 2 , and the air permeability is ≥3000g / (m 2 ·24h), preferably the grammage is 30-40g / m 2 . Low grammage breathable film layer is polyethylene breathable film or polypropylene breathable film or polylactic acid breathable film, and the grammage is 13-15g / m 2 , and the air permeability is ≥3000g / (m 2 ·24h).
