Abstract
The invention discloses a damp-proof packing material comprising an inner layer, a sub inner layer, a sub outer layer and an outer layer which are bonded mutually. The inner layer is a polyethylene layer, the sub inner layer is a nylon layer, the sub outer layer is an aluminum foil layer, and the outer layer is a bilaterally oriented polypropylene layer or polystyrene layer. Since the polyethylene layer, the nylon layer, the aluminum foil layer and the bilaterally oriented polypropylene layer or the polystyrene layer have high water vapor transmission rate barrier property and oxygen transmission rate barrier property, water and oxygen in air can be isolated effectively, and a damp proofing effect can be achieved. In addition, antistatic liquid coated on the outer layer can resist electromagnetic interference.
Description
Technical field
The present invention relates to a kind of packing, relate in particular to a kind of moisture-proof packaging material.
Background technology
Impact after electronic devices and components make moist mainly is to occur in the electronic devices and components heat treatment process, and high temperature particularly is such 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 owing to 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 also is called the difference of pressure damage by people.Difference of pressure damage on the one hand may be because the electronic devices and components damage seriously cause the inefficacy of product direct function, can check out as last dispatching from the factory.And on the other hand can be because the trickle damage of electronic devices and components inside, and when measuring ability, do not lose efficacy, but in follow-up use, cause the problems such as product life is of short duration, total quality is not high, bring very bad impact to enterprise.
Summary of the invention
Technical matters for above-mentioned existence the objective of the invention is: proposed a kind of packing with moisture effect.
Technical solution of the present invention is achieved in that a kind of moisture-proof packaging material, comprises internal layer bonded to each other, inferior internal layer, inferior skin and skin, and 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, described internal layer, inferior internal layer, inferior skin and outer four thickness sums are 0.005～0.18mm.
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.
Because the utilization of technique scheme, the present invention compared with prior art has following advantages:
Moisture-proof packaging material of the present invention, polyethylene layer, nylon layer, aluminium foil layer and Biaxially oriented polypropylene layer (or polyester alkene layer) all have stronger moisture-vapor transmission barrier and OTR oxygen transmission rate barrier, can well intercept airborne moisture and oxygen, dampproof effect.
Description of drawings
Below in conjunction with accompanying drawing technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of moisture-proof packaging material of the present invention;
Wherein: 1, internal layer; 2, inferior internal layer; 3, inferior skin; 4, skin.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described.
Of the present invention a kind of moisture-proof packaging material as shown in Figure 1 comprises internal layer bonded to each other 1, inferior internal layer 2, inferior outer 3 and outer 4, and described internal layer 1 is polyethylene layer; Described time internal layer 2 is nylon layer; Described time outer 3 is aluminium foil layer; Described outer 4 is Biaxially oriented polypropylene layer or polyester alkene layer.
Moisture-proof packaging material of the present invention, polyethylene layer, nylon layer, aluminium foil layer and Biaxially oriented polypropylene layer (or polyester alkene layer) all have stronger moisture-vapor transmission barrier and OTR oxygen transmission rate barrier, can well intercept airborne moisture and oxygen, dampproof effect.
Above-mentioned moisture-proof packaging material, described internal layer, inferior internal layer, inferior skin and outer bonded to each other by glue.
Above-mentioned moisture-proof packaging material, when described internal layer, inferior internal layer, inferior skin and outer four thickness sums were 0.005～0.18mm, moisture effect was best.
Above-mentioned moisture-proof packaging material, 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.
Above-described embodiment only is explanation technical conceive of the present invention and characteristics; its purpose is to allow the personage that is familiar with technique can understand content of the present invention and is implemented; can not limit protection scope of the present invention with this; all equivalences that Spirit Essence is done according to the present invention change or modify, and all should be encompassed in protection scope of the present invention.
