Abstract
The utility model relates to the non-woven fabrics fields of packaging material, it specifically discloses a kind of for wrapping up the compound nonwoven cloth of spontaneous heating packet, it is characterized in that, from inside to outside successively including the spun-bonded non-woven fabrics layer made of PET material, the first hydrophilic nonwoven layer of cloth and the second hydrophilic nonwoven layer of cloth made of PP material made of PP material.Provided by the utility model for wrapping up the compound nonwoven cloth of spontaneous heating packet, high temperature resistant, water imbibition is strong, and the bisque that can obstruct exothermic material is flowed out from non-woven fabrics.
Description
Technical field
The utility model relates to the non-woven fabrics fields of packaging material, more particularly, to wrap up the compound nothing of spontaneous heating packet
Woven fabric.
Background technique
With people's lives tempo increase, the instant food with heating pack bring more convenient with fast.And
And people, when camp or go on a hike outdoors, fever instant food is not necessarily to power supply, is not necessarily to open fire, it is thus only necessary to
Spontaneous heating Bao Jiashui can be heated automatically, provide cuisines for people.
The heating composition of spontaneous heating packet all includes various metals powder such as iron powder, aluminium powder, magnesium powder and calcium oxide substantially
Deng generating exothermic chemical reaction after meeting water, and then heated automatically to food.The packaging of the spontaneous heating packet of commercial type
The non-woven fabrics that bag is all made of single layer is made, and non-woven fabrics has nontoxic and porous characteristic, can promptly make water and fever
Material reacts, but in heating process, due to the rapid expansion of exothermic material, single-layer nonwoven is caused to rupture, so that
Exothermic material is flowed out from non-woven fabrics.
Utility model content
The purpose of this utility model is that being directed to the existing state of the art, provide a kind of for wrapping up the compound of spontaneous heating packet
Non-woven fabrics.
In order to achieve the above objectives, the utility model adopts the following technical solution: a kind of for wrapping up the compound of spontaneous heating packet
Non-woven fabrics, which is characterized in that from inside to outside successively include the spun-bonded non-woven fabrics layer made of PET material, made of PP material
First hydrophilic nonwoven layer of cloth and the second hydrophilic nonwoven layer of cloth made of PP material.
The one side of the first hydrophilic nonwoven layer of cloth by glue and spun-bonded non-woven fabrics layer it is compound, another side by glue with
Second hydrophilic nonwoven layer of cloth is compound.
The glue is polyurethane adhesive.
The spun-bonded non-woven fabrics layer with a thickness of 40-45 μm.
The first hydrophilic nonwoven layer of cloth with a thickness of 20-30 μm.
The second hydrophilic nonwoven layer of cloth with a thickness of 20-30 μm
The utility model has the beneficial effects that: provided by the utility model for wrapping up the composite non woven of spontaneous heating packet
Cloth, high temperature resistant, water imbibition is strong, and the bisque that can obstruct exothermic material is flowed out from non-woven fabrics.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of compound nonwoven cloth.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and embodiments:
Refering to Figure 1, it is a kind of for wrapping up the compound nonwoven cloth of spontaneous heating packet, it from inside to outside successively include by PET
Spun-bonded non-woven fabrics layer 1 made of material, the first hydrophilic nonwoven layer of cloth 2 made of PP material and the second parent made of PP material
Water nonwoven layer 3.
The one side of first hydrophilic nonwoven layer of cloth 2 is compound by glue and spun-bonded non-woven fabrics layer 1, and another side passes through glue and the
Two 3 layers of hydrophilic nonwoven fabrics are compound.
The glue used is polyurethane adhesive.
Spun-bonded non-woven fabrics layer 1 with a thickness of 40-45 μm.
First hydrophilic nonwoven layer of cloth 2 with a thickness of 20-30 μm.
Second hydrophilic nonwoven layer of cloth 3 with a thickness of 20-30 μm.
1 good permeability of spun-bonded non-woven fabrics layer made of PET material, light-weight, intensity height and high temperature resistant.By PP material
2 water imbibitions of manufactured first hydrophilic nonwoven layer of cloth are extremely strong, can promptly draw the water of addition, quickly occur with spontaneous heating material
Chemical reaction, the second hydrophilic nonwoven layer of cloth 3 made of PP material, other than water imbibition is strong, moreover it is possible to obstruct exothermic material
Bisque outflow.
Certainly, illustrated above is only the preferred embodiment of the utility model, and the use of the utility model is not limited with this
Range, therefore, it is all made in the utility model principle it is equivalent change should be included in the protection scope of the utility model.
