Abstract

The utility model relates to a breathable anti-reverse osmosis packaging material structure which is used for packaging a drying agent or used as an inner layer packaging material for a container. The breathable anti-reverse osmosis packaging material structure is a layered product and comprises an anti-reverse osmosis layer and more than one breathable layer, wherein the breathable layer is a PE breathable film and/or PET breathable film, at least one layer is an inner layer breathable film which is a printing breathable film printed with patterns or characters, the breathable layer or anti-reverse osmosis layer is compounded outside the printing breathable film, and the anti-reverse osmosis layer is non-woven fabric and/or paper. With good moisture-permeable and air-permeable effects, the breathable anti-reverse osmosis packaging material structure provided by the utility model does not cause secondary pollution to a packaged product and has the advantages of prevention of reverse osmosis of moisture and the like.

Description

Ventilative anti-reverse osmosis packaging structure

Technical field

The utility model relates to a kind of ventilative anti-reverse osmosis packaging structure, for packing drier or in the internal layer packaging material of container.

Background technology

Desiccant package can be selected nonwoven, paper, nontoxic microporous plastic sheet and above several any combination.Although with respect to different drier, it is also different to the selection of packaging material, and suitable desiccant package material needs nothing but to possess following Some features: intensity is high, lightweight, waterproof, and chemical resistance, wear-resistant, the character such as ageing-resistant.But common packaging material have all been ignored a problem, when absorbing airborne moisture content, drier reaches after its saturation degree, and just have a certain amount of moisture content and from the hole of desiccant package material, return to ooze out and, thereby polluted the article that need to keep dry.

Therefore, applicant improves above-mentioned packaging material, this packaging material of using for packing drier, comprises air-permeable layer and counnter attack infiltration layer, and described ventilative anti-reverse osmosis packaging structure is composited by one or more layers of PE ventilated membrane and one or more layers of nonwoven polypropylene fabric hot pressing.Have wet, air permeable effect is good, when drier degree of reaching capacity, preventing that moisture content from returning oozes, hot strength is high, shrinkage factor is low.

But, because need printing on packing timber, to facilitate identification, make printing-ink produce secondary pollution to product.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of ventilative anti-reverse osmosis packaging structure is provided, makes printing-ink can not have pollution to the product of packaging.

The technical scheme that the utility model technical solution problem adopts is: a kind of ventilative anti-reverse osmosis packaging structure, for laminar product, comprise counnter attack infiltration layer and air-permeable layer more than one deck, wherein: described air-permeable layer is PE ventilated membrane and/or PET ventilated membrane, having one deck at least is internal layer ventilated membrane, this internal layer ventilated membrane is the printing breathable films that has printed patterns or word, composite ventilating layer and/or counnter attack infiltration layer outside described printing breathable films; Described counnter attack infiltration layer is nonwoven and/or paper.Because surface does not have ink, use safety.

In order to adapt to the needs of packing electronic product, at described ventilative anti-reverse osmosis packaging structure outermost layer, there is antistatic coat.

The beneficial effects of the utility model are:

1, not only thoroughly wet, air permeable effect is good, and can not cause secondary pollution to the product of packaging;

2,, when drier degree of reaching capacity, preventing that moisture content from returning oozes;

3, hot strength is high, and shrinkage factor is low;

4, after the utility model having been carried out to the painting of antistatic table, can be used for the packing of product that has requirement to antistatic.

The specific embodiment

embodiment 1

Refer to shown in the structural representation of the ventilative anti-reverse osmosis packaging structure of Fig. 1 the utility model, a kind of ventilative anti-reverse osmosis packaging structure, for laminar product, comprise counnter attack infiltration layer and air-permeable layer more than one deck, wherein: described air-permeable layer is PE ventilated membrane 1(or PET ventilated membrane), having one deck at least is internal layer ventilated membrane, and this internal layer ventilated membrane is the printing breathable films 3 that has printed patterns or word, composite ventilating layer and/or counnter attack infiltration layer outside described printing breathable films; Described counnter attack infiltration layer is nonwoven 2(or paper).

embodiment 2

As shown in the structural representation of ventilative anti-reverse osmosis packaging structure that Fig. 2 is the second embodiment, for the ventilative anti-reverse osmosis packaging structure of another kind, comprise counnter attack infiltration layer and air-permeable layer more than one deck, wherein: described air-permeable layer is PE ventilated membrane 1 ' (or PET ventilated membrane), having one deck at least is internal layer ventilated membrane, this internal layer ventilated membrane is the printing breathable films 3 ' that has printed patterns or word, composite ventilating layer and/or counnter attack infiltration layer outside described printing breathable films; Described counnter attack infiltration layer is nonwoven 2 ' (or paper), at the described outermost upper surface of ventilative anti-reverse osmosis packaging structure and lower surface, has anti-static coating 4,4 '.At skin coating antistatic liquid, reach anti-static effect, can use in electronic product.

Also can only for the packaging material layer towards product, apply anti-static coating.

Claims

1. a ventilative anti-reverse osmosis packaging structure, for laminar product, comprise counnter attack infiltration layer and air-permeable layer more than one deck, it is characterized in that: described air-permeable layer is PE ventilated membrane and/or PET ventilated membrane, having one deck at least is internal layer ventilated membrane, this internal layer ventilated membrane is the printing breathable films that has printed patterns or word, composite ventilating layer or counnter attack infiltration layer outside described printing breathable films; Described counnter attack infiltration layer is nonwoven and/or paper.
