Abstract
The utility model relates to a damp-proof packaging bag. A bag body is formed by two pieces of damp-proof packing material in a three-edge sealing mode. A bag opening of the bag body is sealed through a sealing opening. The damp-proof packing material comprises an inner layer, a secondary inner layer, a secondary outer layer and an outer layer which are attached to one another. The inner layer is a polyethylene layer, the secondary inner layer is a nylon layer, the secondary outer layer is an aluminum foil layer, and the outer layer is a biaxially oriented polypropylene layer or a polyester layer. According to the damp-proof packaging bag, the polyethylene layer, the nylon layer, the aluminum foil layer and the biaxially oriented polypropylene layer (or the polyester layer) of the damp-proof packing material all have the strong water vapor permeability barrier property and the oxygen permeability barrier property, the moisture and oxygen in the air can be well obstructed, the damp-proof packaging bag is used for packaging electronic components, and the effect that the electronic components are prevented from being affected with damp can be achieved.
Description
Technical field
The utility model relates to a kind of packaging bag, relates in particular to a kind of moisture barrier bag of electronic part packaging.
Background technology
Impact after electronic devices and components make moist, is mainly to occur in electronic devices and components heat treatment process, and high temperature particularly, as Reflow Soldering, high-temperature baking etc.Electronic devices and components after making moist are in these pyroprocesses, the moisture content of electronic devices and components inside will gasify because temperature raises, the moisture content volume of gasification sharply increases, thereby cause the het expansion of electronic devices and components, cause the difference of pressure of electronic devices and components inside and outside, so caused electronic devices and components cracking, layering, peel off, tiny crack and to device damages such as " puffed rices ".This class damage is also called difference of pressure by people and damages.Difference of pressure damage, may lose efficacy because electronic devices and components damage seriously cause product direct function on the one hand, was dispatching from the factory as last and can check out.And on the other hand can be due to the trickle damage of electronic devices and components inside, and do not lose efficacy when measuring ability, but in follow-up use, cause the problem ，Gei enterprises such as product life is of short duration, total quality is not high to bring very bad impact.
Utility model content
The utility model object is that a kind of moisture-proof packing bag that can prevent that electronic devices and components from making moist before heat treatment is provided in order to overcome the deficiencies in the prior art.
For achieving the above object, the technical solution adopted in the utility model is: a kind of moisture-proof packing bag, and described bag body is formed by two moisture-proof packaging materials, three banding knots; The sack of described bag body seals by seal; Described moisture-proof packaging material comprises internal layer bonded to each other, inferior internal layer, inferior skin and skin; Described internal layer is polyethylene layer; Described internal layer is nylon layer; Described time skin is aluminium foil layer; Described skin is Biaxially oriented polypropylene layer or polyester alkene layer.
Preferably, described internal layer, inferior internal layer, inferior skin and outer bonded to each other by glue.
Preferably, the thickness of described internal layer is 0.003～0.15mm; The thickness of described internal layer is 0.015～0.025mm; Described time outer field thickness is 0.005～0.012mm; Described outer field thickness is 0.012～0.035mm.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
Moisture-proof packing bag of the present utility model, because polyethylene layer, nylon layer, aluminium foil layer and the Biaxially oriented polypropylene layer (or polyester alkene layer) of moisture-proof packaging material all has stronger moisture-vapor transmission barrier and OTR oxygen transmission rate barrier, can well intercept airborne moisture and oxygen, with this moisture-proof packing bag, electronic devices and components are packed, can be played the effect that prevents that electronic devices and components from making moist.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
The structural representation that accompanying drawing 1 is moisture-proof packing bag of the present utility model;
Wherein: 1, bag body; 2, seal; 3, internal layer; 4, inferior internal layer; 5, inferior skin; 6, skin.
The specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Described in the utility model a kind of moisture-proof packing bag as shown in Figure 1, described bag body 1 is formed by two moisture-proof packaging materials, three banding knots; The sack of described bag body 1 seals by seal 2; Described moisture-proof packaging material comprises internal layer bonded to each other 3, inferior internal layer 4, inferior outer 5 and outer 6; Described internal layer 3 is polyethylene layer; Described time internal layer 4 is nylon layer; Described time outer 5 is aluminium foil layer; Described outer 6 is Biaxially oriented polypropylene layer or polyester alkene layer.
Moisture-proof packing bag of the present utility model, during use, is placed in moisture-proof packing bag by electronic devices and components, then uses seal that sack is sealed.Because polyethylene layer, nylon layer, aluminium foil layer and the Biaxially oriented polypropylene layer (or polyester alkene layer) of moisture-proof packaging material all has stronger moisture-vapor transmission barrier and OTR oxygen transmission rate barrier, can well intercept airborne moisture and oxygen, play moisture effect, prevent that electronic devices and components from making moist, making, in electronic devices and components heat treatment process, difference of pressure not to occur damages, improved product life and total quality ，Gei enterprise brings positive impact.
Above-mentioned moisture-proof packing bag, described internal layer, inferior internal layer, inferior skin and outer bonded to each other by glue.
Above-mentioned moisture-proof packing bag, general, the thickness of described internal layer is 0.003～0.15mm; The thickness of described internal layer is 0.015～0.025mm; Described time outer field thickness is 0.005～0.012mm; Described outer field thickness is 0.012～0.035mm, and moisture effect is best
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
