Description
Technical field
Packaging technical field of membrane is the utility model is related to, is especially a kind of fresh-keeping multi-layer compound package film.
Background technology
The core technology of the packaging film fresh-keeping for vegetables and fruits is the regulation of the gas and humidity to vegetables and fruits local environment, needs
Breathe freely, but can not too breathe freely, it is necessary to moisturizing, but can not too moisturizing；In the prior art, the fresh-keeping packaging film of vegetables and fruits is general
For monofilm, such as polyethylene film, and the applicant is intended to study and a kind of belongs to the fresh-keeping with MULTILAYER COMPOSITE bag of structure of composite membrane
Film is filled, can be more beneficial to the gas of vegetables and fruits local environment and the regulation of humidity.
Utility model content
Technical problem to be solved in the utility model is the defects of overcoming prior art, there is provided one kind is fresh-keeping to use multilayer
Composite package film, it is structure of composite membrane, can be more beneficial to the gas of vegetables and fruits local environment and the regulation of humidity.
In order to solve the above technical problems, the utility model proposes a kind of fresh-keeping multi-layer compound package film, it includes N layers
Film, N are the natural number more than 1, and the first tunic is located at external environment side, and n-th layer film is located at package interior side, the first tunic
At least one layer of wall for being used to accommodate gas is provided between n-th layer film, the first tunic is provided with positioned at the interval of the superiors
The first through hole that is connected with external environment of layer, n-th layer film is provided with the will connected positioned at undermost wall with package interior
Two through holes, the third through-hole for connecting adjacent spacer is provided between the first tunic and n-th layer film.
After said structure, compared with prior art, the utility model has advantages below：In order to make it easy to understand, with
Packaging bag is illustrated to explain advantage of the present utility model, and packaging bag can simply be interpreted as sealing into one using two panels packaging film
Individual sack, the packaging film is all using the utility model structure, or one of region uses the utility model structure, two kinds
；Wall can be understood as an air chamber, and the air in air chamber has certain density water and gas, and gas indoor water is gentle
The passage that the passage of body disengaging packaging bag is first through hole, third through-hole, the second through hole and each wall of combination are formed, then,
By change first through hole, third through-hole, the second through hole the quantity either size in hole or the situation to stagger, Huo Zhegai
The thickness of changing distance layer, we can be produced with specific ventilative and performance of keeping humidity packaging bag, so as to be applied to different vegetables
The fresh-keeping requirement of fruit, in other words, the utility model structure provide the regulation option of more horn of plenty, prior art monofilm
In the case of, in general, thickness can only be adjusted, or adjusted in itself from material, for example change density, therefore compare existing skill
Art, the utility model are structure of composite membrane, can be more beneficial to the gas of vegetables and fruits local environment and the regulation of humidity, in addition, by
It is structure of composite membrane in the utility model, so than prior art single layer structure, intensity is high, such as can be with portable.
As an improvement, the through hole of adjacent layer is dislocatedly distributed, and so, more conducively moisturizing.
As an improvement, some tunics include non-flatted membrane, between the film of each non-flatted membrane and upper strata adjoining described in formation
Wall, so, be easy to manufacture composite membrane, the wall of formation can be kept connect with air, maintain certain density water with
Gas, when deployed, for example by heat-sealing, wall periphery is just closed.

Embodiment
The utility model is described in further detail below：
The utility model is fresh-keeping to use multi-layer compound package film, and it includes N tunics, and N is the natural number more than 1, the first tunic 1
Positioned at external environment side, n-th layer film is located at package interior side, and at least one layer is provided between the first tunic 1 and N tunics
For accommodating the wall 6 of air, the first tunic 1 is provided with first will connected positioned at the wall 6 of the superiors with external environment
Through hole 8, n-th layer film are provided with the second through hole 9 that will be connected positioned at undermost wall 6 with package interior, the He of the first tunic 1
The third through-hole 10 for connecting adjacent spacer 6 is provided between n-th layer film.
Each layer in N tunics, can be third layer film 3, in a Rotating fields or sandwich construction, such as Fig. 3
The sandwich construction that the connection of four tunics 4 is formed, the sandwich construction can regard one layer as.
Shown in Fig. 1, N five, composite membrane includes five tunics, respectively the first tunic 1, the second tunic 2, third layer film 3,
Four tunics 4, layer 5 film 5, wherein the second tunic 2, third layer film 3, the 4th tunic 4, layer 5 film 5 are non-flatted membrane.
Described wall 6 is formed between each non-flatted membrane and the film of upper strata adjoining.
The non-flat configuration of non-flatted membrane sets some raised 7 for the surface of the side of film, and non-flatted membrane abuts with upper strata
Film between pass through some raised 7 and form described wall 6.
Shown in Fig. 2, the adjacent intermembranous tie point or bar 13 for being provided with connection adjacent membranes, in same layer, each tie point or bar 13
Between space self-assembling formation described in wall 6；Tie point or bar 13 can be glue point or adhesive tape.
As change, the cross sectional shape of the non-flat configuration of non-flatted membrane can change, such as using waveform, i.e. ripple
Unrestrained structure, as shown in figure 3, so, the increasingly complex wall 6 of internal structure can be formed, to ventilative and performance of keeping humidity more
Fine adjustments have certain help, and lateral direction penetrating structure 11 can be set between each wave to penetrate each other, for example penetrate
Hole, so that the internal run-through of wall 6.
As shown in figure 3, N is six, composite membrane includes six tunics, the first tunic 1, the second tunic 2, third layer film 3, the 4th layer
Film 4, layer 5 film 5, layer 6 film 12, wherein third layer film 3, layer 5 film 5 are non-flatted membrane, and non-flat configuration is wave
Structure.
A piece of packaging film, it integrally can use structure of the present utility model or some region new for this practicality
The structure of type, and other regions are other structures, than as shown in figure 4, left-hand component is structure of the present utility model, and the right portion
Each tunic then fits together completely in point.
Described above is only better embodiment of the present utility model, therefore all according to described in the utility model patent application range
