Abstract
The utility model provides a warm-paster packaging film which belongs to the technical field of a compound packaging material. The packaging film comprises a nonwoven cloth layer at an outer layer, and is characterized in that a ventilating film layer is compounded at the inner surface of the nonwoven cloth layer, and the nonwoven cloth layer is compounded with the ventilating film layer by a dot-matrix cloth adhesive in a gluing manner. With the characteristics of unique design, reasonable structure, uniform ventilation and high packaging intensity, the warm-paster packaging film leads lasting as well as uniform heating of an entire warm paster, and leads users to feel comfortable; meanwhile, the encapsulating technique of inclusions of the warm paster can be simplified, so as to reduce the manufacturing cost of the warm paster.
Description
Technical field
The utility model belongs to field of packaging material, is specifically related to the warm packaging film that pastes of a kind of compound type.
Background technology
The warm subsides, utilize under the effect of synthetic poly-mer oxygen in air such as iron, stone, active carbon, inorganic salts, water exothermal reaction takes place, only need be attached to corresponding ailing position, just can alleviate and eliminate pain about half an hour at once, being the desirable health treatment that patient's pain relievings health cares such as cold pain are met in arthritis, scapulohumeral periarthritis, pain in waist and lower extremities, rheumatism and rheumatoid disease, chilly discomfort, coolness of extremities, injury, also is simultaneously the resisting cold guarantee of the best when being engaged in low temperature environment work such as mountain-climbing, skiing, fishing, tourism, geology exploration or outdoor activities.The permeability to air of packing is the key point of its performance effect concerning warm the subsides, so adopt nonwoven fabrics to coat the warm subsides structure of raw material layer in the market substantially, though this traditional warm subsides structure possesses air permeability and good, but the raw material that includes is because of the minimum easily seepage of particle order degree, causes including raw material and gradually reduces and reduce effect.
The utility model content
The utility model aims to provide a kind of warm packaging film technical scheme of pasting of compound type with good permeability to air and packaging intensity, to overcome problems of the prior art.
Described warm subsides packaging film comprises outer field nonwoven layer, it is characterized in that the nonwoven layer inside face is compound ventilative rete is set, and is gluing compound by dot matrix cloth glue between nonwoven layer and the ventilative rete.
Described warm subsides packaging film is characterized in that described nonwoven layer is by 40g/m
2-80g/m
2Nonwoven fabrics constitute.
Described warm subsides packaging film is characterized in that described ventilative rete is that ventilative PE co-extrusion film or the ventilative CPP film of 20-80 μ m constitutes by thickness.
Described warm subsides packaging film is characterized in that between nonwoven layer and the ventilative rete gluing compound by dot matrix cloth glue dry type.
Above-mentioned warm subsides packaging film design is unique, rational in infrastructure, having has uniform permeability to air and good packaging intensity, makes whole warm subsides heating evenly, lastingly, allows the user feel comfortable, can simplify simultaneously warm packaging technology of pasting inclusion, reduce warm manufacturing cost of pasting.
Description of drawings
Fig. 1 is the utility model structural representation;
Fig. 2 is this practical cross section structure scheme drawing.
Among the figure: 1-nonwoven layer, 2-dot matrix cloth glue, the ventilative rete of 3-.
The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description:
As shown be the warm packaging film that pastes, comprise the ventilative rete 3 of outer field nonwoven layer 1 and internal layer, nonwoven layer 1 is by 40g/m
2-80g/m
2Nonwoven fabrics constitute, nonwoven layer 1 inside face is compound to be provided with ventilative rete 3, it is ventilative PE co-extrusion film or the ventilative CPP film of 20-80 μ m that ventilative rete 3 adopts thickness; Gluing compound between nonwoven layer 1 and the ventilative rete 3 by dot matrix cloth glue 2 dry types.Both can guarantee the bond strength between nonwoven layer 1 and the ventilative rete 3, and can avoid justifying face coating glue again and influence permeability to air.
