Abstract
The utility model discloses an air-permeable plastic film which comprises a plastic film and is characterized in that: an air hole is formed on the plastic film, and an air-permeable module covering the air hole is fixed on the air hole. The air-permeable plastic film disclosed by the utility model has reasonable structure and wide application range, is convenient to use, and can be applied to any occasions needing air permeation. The air-permeable plastic film disclosed by the utility model can be used as a medical or food preservative film and a packaging film needing air permeation, and is particularly suitable to be used as a bacteria bag for culturing edible fungi.
Description
Technical field
The utility model relates to a kind of plastic film, particularly a kind of breathable plastic film.
Background technology
Plastic film of the prior art is sir-tight plastic film, and when it was used for connection with wrapping of piece, can't be applicable to needed ventilative occasion.For example, with traditional edible fungus bag that plastic film is made, its ventilative pattern generally all is to utilize the sponge ventilating cover ventilative.In use, utilize the common plastics film to process the bacterium bag earlier, behind the packed full culture base-material of bacterium, put the collar at the bacterium sack, the ventilating cover that on the collar, covers the band sponge is then breathed freely.Therefore, plastic film of the prior art uses very inconvenience, narrow range applicatory.
Summary of the invention
The utility model technical matters to be solved is the deficiency to prior art, provides a kind of structure breathable plastic film more reasonable, easy to use, applied widely.
This is that technical matters to be solved is to realize through following technical scheme.The utility model is a kind of breathable plastic film, comprises plastic film, is characterized in: on plastic film, be provided with breather hole, on breather hole, be fixed with the ventilated membrane piece that covers breather hole.
The set breather hole of the utility model breathable plastic film can be single through hole, the delicate hole that several apertures of also can serving as reasons are formed.
The utility model technical matters to be solved can also further realize through following technical scheme.Above-described breathable plastic film is characterized in: described plastic film rolling is provided with, and described breather hole and upward set ventilated membrane piece thereof evenly are located on the plastic film at interval.On plastic film, can also be interval with wire and tear the hole.Like this, just can do the plastic film of rolling, use more convenient.
The invention also discloses a kind of preparation method of as the described breathable plastic film of above technical scheme; The steps include: to get plastic film; On plastic film, go out earlier breather hole; Press the size requirements intercepting ventilated membrane piece of breather hole then, at last the ventilated membrane piece adopt is pasted or the mode of welding is fixed on the plastic film and covers breather hole, promptly get.
Ventilated membrane piece described in the utility model technical scheme is to be processed by ventilated membrane, and described ventilated membrane is also claimed filtering membrane, drenched film nonwoven fabrics, overlay film nonwoven fabrics, and it can be disclosed any material ventilative, filter effect that has in the prior art; Preferably process with materials such as PP, PTFE; Can use the commercially available prod, it can be an individual layer, also can be the ventilative piece of multiple layer combination; Use occasion according to the utility model breathable plastic film is selected for use; Preferably can breathe freely, filter the ventilated membrane of bacterium, the filtering accuracy of ventilated membrane generally reaches about 0.02-0.1 μ m, also can select the filtering accuracy of ventilated membrane according to the filtration needs for use.
Compared with prior art, the utility model breathable plastic membrane structure is more reasonable, easy to use, applied widely, goes for the ventilative occasion of any needs.The utility model breathable plastic film can be used preservative film as medical or food, needs ventilative packaging film, is particularly suitable for using the bacterium bag as the edible mushroom cultivation.
Description of drawings
Fig. 1 is a kind of structural representation of the utility model.
The specific embodiment
Following with reference to accompanying drawing, further describe the concrete technical scheme of the utility model, so that those skilled in the art understands the utility model further, and do not constitute restriction to its right.
Its preparation method is: get plastic film, on plastic film, go out breather hole earlier, press the size requirements intercepting ventilated membrane piece 2 of breather hole then, the mode of at last 2 employings of ventilated membrane piece being pasted is fixed on the plastic film 1 and covers breather hole, promptly gets.
