Abstract
A heat-generating bag is composed of an external bag, an internal bag with a non-woven fabric-polyethylene film surface and another non-woven fabric-slightly air-permeable polyethylene film furface, and a heat-releasing material, which is put in said internal bag and contains iron powder, inorganic salt, activated carbon, water and wood powder. Its advantages are smooth and durable generation of heat and low cost.
Description
Technical field
The present invention relates to a kind of hot packing articles for use, particularly relate to a kind of heating bag.
Background technology
A kind of non-adhesive type heating bag is arranged in the market, and it is that inorganic salt, iron powder, active carbon, wood powder are put into the inner bag that the non-woven fabric compounded polyethylene film in the hole that gets beat up is made, and inner bag is contained in air-locked outer bag, tear outer bag in use, take out inner bag, the aperture of inner bag penetrates air in the inner bag, because the hole that the machinery on the inner bag is beaten, the bigger heating of hole is rapid, and in use, content is prone to tenesmus, irregular phenomenon, in addition, punch lost time, cost height on the inner bag.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of heating bag is provided, it can continue slow heat release in use, and cost is reduced.
Technical scheme of the present invention is summarized as follows:
A kind of heating bag, comprise exothermic material, inner bag, outer bag, described exothermic material comprises by weight percentage: iron powder 25～85%, inorganic salt 1～12%, active carbon 3～50%, water 0～40%, wood powder 0～10%, described exothermic material is placed in the inner bag, and described inner bag is placed in the outer bag of being made by gas impermeable material, bag material simultaneously is non-woven fabric compounded polyethylene film in described, and another side is the little ventilative polyethylene film of non-woven fabric compounded atresia.
Described inorganic salt is one of sulfate, sulphite, sulphurizing salt, nitrate, nitrite, carbonate, silicate, halide salt or phosphate.
The present invention is because the one side of inner bag has been replaced the non-woven fabric compounded polyethylene film of original punching by the little ventilative polyethylene film of non-woven fabric compounded atresia, it is little ventilative, make air slowly see through inner bag, the exothermic oxidation reaction in the bag is not fierce, so heating effect steadily, lastingly; Simultaneously, owing to need not punch, reduced drilling process in the manufacturing process, consuming time few, cost descends; In addition, the characteristics that inner bag also can not have drum, do not drop reach beyond thought effect.
The specific embodiment
The present invention is further illustrated below in conjunction with embodiment: express 12 embodiment of the present invention down, unit is gram.
