Abstract
The utility model provides a waterproof packaging film, which relates to the technical field of waterproof packaging films and comprises a base film and a nano-pore film, wherein the nano-pore film is covered on one surface of the base film and is bonded by an adhesive.
Description
Technical Field
The utility model relates to the technical field of waterproof packaging films, in particular to a waterproof packaging film.
Background
The food packaging film can effectively isolate external pollutants and microorganisms, prevent food from being influenced by factors such as environment, moisture, oxygen, light and the like, prolong the shelf life of the food and keep the freshness and sanitation and safety of the food.
The existing waterproof packaging film has lower gas and moisture permeability, and for certain food vegetables, ventilation and moisture permeability are needed to keep fresh and stable, and lower gas and moisture permeability can lead to moisture and deterioration in the package.
Disclosure of Invention
The utility model aims to provide a waterproof packaging film, which aims to solve the problems that the waterproof packaging film in the prior art has lower gas and moisture permeability, and certain food vegetables need ventilation and moisture permeability to keep fresh and stable, and the lower gas and moisture permeability can cause humidity and deterioration in the packaging.
In order to achieve the above purpose, the utility model adopts the following technical scheme: the waterproof packaging film comprises a base film and a nano-pore film, wherein the nano-pore film covers one surface of the base film and is bonded through an adhesive.
Preferably, the distribution of micropores on the nanoporous film is 10-1000/cm 2 。
Preferably, the pore size of the micropores is 0.1-10 μm.
The beneficial effects of the utility model are as follows:
the waterproof packaging film has good waterproof performance and high-efficiency air permeability, can keep the interior of an article dry and clean, and can discharge excessive moisture at the same time, so that the problems of mildew, oxidization, deterioration and the like are avoided.
Drawings
Fig. 1 is a schematic structural view of an embodiment of the present utility model.
In the figure: 1. a base layer film; 2. a nanoporous film; 3. an adhesive; 4. micropores.
Detailed Description
The following describes the embodiments of the present utility model further with reference to the drawings.
As shown in fig. 1, a waterproof packaging film comprises a base film 1 and a nanoporous film 2, wherein the nanoporous film 2 is covered on one side of the base film 1 and is bonded by an adhesive 3.
The base film 1 may be a film made of polyethylene, polypropylene, polyester or other plastic materials having certain waterproof properties and mechanical strength.
The nanoporous film 2 may be a film of porous structure composed of nanoscale fibers, having high porosity and high permeabilityThe gas performance can allow water vapor to pass through and prevent liquid water from penetrating, the pore diameter of the nano-pore membrane 2 can be 0.1-10 mu m, and the distribution of micropores 4 on the nano-pore membrane 2 is 10-1000/cm 2 。
The adhesive 3 may be an acrylic, epoxy or other adhesive 3 having good weatherability and chemical resistance.
The waterproof packaging film has good waterproof performance and high-efficiency air permeability, can keep the interior of an article dry and clean, and can discharge excessive moisture at the same time, so that the problems of mildew, oxidization, deterioration and the like are avoided.
In the description of the present utility model, unless explicitly stated and limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; can be directly connected or indirectly connected through an intermediate medium, and can be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
Furthermore, it should be understood that although the present disclosure describes embodiments, not every embodiment is provided with a separate embodiment, and that this description is provided for clarity only, and that the disclosure is not limited to the embodiments described in detail below, and that the embodiments described in the examples may be combined as appropriate to form other embodiments that will be apparent to those skilled in the art.
