Abstract
The utility model discloses a gas-permeable membrane cover. The gas-permeable membrane cover is characterized by comprising a first base material layer, a second base material layer and a bonding coating layer, wherein a first exhaust reserved band is arranged on the first base material layer, the second base material layer is arranged on the first base material layer, the second base material layer adheres to the first base material layer through the bonding coating layer, and a second exhaust reserved band is arranged at the position, corresponding to the first exhaust reserved band, of the bonding coating layer. By the adoption of the gas-permeable membrane cover of the structure, the good ventilating effect is achieved under the conditions of heating by a microwave oven and the like, and compared with the traditional method that ventilation holes are cut in a package manually in advance, more time and more effort are saved.
Description
Technical field
The utility model relates to a kind of complex film, especially a kind of ventilative membrane cover.
Background technology
From physical angle, traditional preservative film has appropriate oxygen permeability and moisture permeability, regulates by fresh-keeping product oxygen content and moisture around, intercepts koniology, thereby extends the freshness date of food.Therefore, to select different preservative films be necessary to different food products.Preservative film on market is divided into two classes substantially now, and a class is common preservative film, is applicable to fridge freshness retaining; One class is microwave-oven fresh-preservation-film, both can be used for fridge freshness retaining, also can be used for micro-wave oven.Rear a kind of preservative film is far superior to common preservative film at the aspect such as heat-resisting, non-toxic.In the use of rear a kind of microwave-oven fresh-preservation-film, usually there is such warning: the first, when the larger food of heating oiliness, should, by preservative film and food maintenance isolated condition, not make the two directly contact.Because when food is heated, food oil may reach very high temperature, preservative film is occurred damaged, is bonded on food.The second, when heat food, should cover after vessel with preservative film, then on preservative film, prick several apertures with spicules such as toothpicks, be beneficial to the evaporation of moisture, prevent from making preservative film explosion because of gas expansion.Concerning most consumers, when use, prick the way of aperture inconvenient, and also happen occasionally owing to usually ignoring the situation that this thing causes heated food to blow in micro-wave oven implosion.
Summary of the invention
For the problems referred to above, the utility model provides a kind of ventilative membrane cover, and the hot gas that this membrane cover produces in use is outwards got rid of all waste hot airs by reserved ventilating groove, finally makes the food energy actv. in this packing absorb heat energy.
In order to realize foregoing invention object, the utility model has disclosed ventilative membrane cover, it is characterized in that, described ventilative membrane cover comprises:
The first substrate layer offers the reserved band of the first exhaust on described the first substrate layer;
The second substrate layer, is arranged on described the first substrate layer;
One bonding coating layer, is bonded in described the second substrate layer on described the first substrate layer, and on described bonding coating layer, the reserved band of corresponding described the first exhaust position arranges the reserved band of the second exhaust.
Reasonable, ventilative membrane cover of the present utility model, is characterized in that,
The material of described the first substrate layer is thermoplastic closure material.
Reasonable, ventilative membrane cover of the present utility model, is characterized in that,
The material of described the second substrate layer comprises poly-ester fibres, nylon, art paper.
Reasonable, ventilative membrane cover of the present utility model, is characterized in that,
The material of described bonding coat comprises glue.
Reasonable, ventilative membrane cover of the present utility model, is characterized in that,
The area of the reserved band of described the first exhaust is greater than the reserved band of described the second exhaust.
The utility model adopts the ventilative membrane cover of said structure, has played good air permeable effect in situations such as microwave-oven-heatings.
Accompanying drawing explanation
Below, with reference to accompanying drawing, for those skilled in the art, to detailed description of the present utility model, above and other object of the present utility model, feature and advantage will be apparent.
Fig. 1 is the cross-sectional view of the utility model one preferred embodiment.
Reference numeral
1 second substrate layer
2 bonding coating layers
The reserved band of 3 first exhausts
4 first substrate layers
The reserved band of 5 second exhausts
6 food containers
The specific embodiment
The sectional structure schematic diagram of ventilative membrane cover one preferred embodiment of basis shown in Figure 1.
Wherein, skin is the second substrate layer 1, can be chosen as nylon, poly-ester fibres (PET), internal layer is the first substrate layer 4, conventionally select the material of thermoplastic sealing property, such as polyethylene etc., between ectonexine, be a bonding coating layer 2, this bonding coating layer 2 is bonded together the first substrate layer 4 and the second substrate layer 1.
The more special structure of the utility model is, offers that the first exhaust is reserved is with 3 in the first substrate layer 4; Offer with 3 position that the second exhaust is reserved is with 5 corresponding the first exhaust of bonding coating layer 2 is reserved.Thus, two exhausts are reserved and are with 3,5 to form a structure from food containers 6 to outside breather hole.The reserved bands of two exhausts can be any shapes, and the first exhaust is reserved is greater than with 3 area that the second exhaust is reserved is with 5.
The first substrate layer 4 that the utility model adopts can be selected poly-ester fibres, nylon, art paper, in order to realize the functions such as printing and advertisement.
When use, first the first substrate layer 4 on the food container 6 that contains the ventilative membrane cover of said structure is removed, then this container is inserted in micro-wave oven and is heated, when food is heated, aqueous vapor rises, be with 3 by the first exhaust in the first substrate layer 4 is reserved, and the second exhaust in bonding coating layer 2 reserved with 5 form from container 6 to outside breather hole structure, can make aqueous vapor from the content of the container 6 whole membrane cover of overflowing, set off an explosion thereby avoid aqueous vapor to accumulate in seal cavity.
Adopt the ventilative membrane cover of said structure, played good air permeable effect in situations such as microwave-oven-heatings, more traditional artificial in advance this packing to be cut to the way of breather hole more time saving and energy saving.
The utility model can be used for boxed cassette and other heat sealable containers of microwave packaging.
All embodiment are only for illustration of the utility model above, but not to restriction of the present utility model, person skilled in the relevant technique, in the situation that not departing from spirit and scope of the present utility model, can also make various conversion or variation, therefore all technical schemes that are equal to also should belong to category of the present utility model and should be limited by each claim.
