Abstract
The utility model relates to the technical field of product external packaging, in particular to a moisture absorption and moisture prevention plastic film for packaging, which comprises a plastic film, wherein the plastic film comprises a base film, a breathable film is arranged at the bottom end of the base film, a plurality of moisture absorption blocks are arranged between the breathable film and the base film, and moisture between a product and the plastic film is absorbed through the moisture absorption blocks, so that the plastic film has a good moisture absorption effect, can effectively absorb redundant moisture on the product, and keeps the product and the plastic film dry.
Description
Technical Field
The utility model relates to the technical field of product external packaging, in particular to a moisture absorption and moisture prevention plastic film for packaging.
Background
As is well known, plastic films are films made of polyvinyl chloride, polyethylene, polypropylene, polystyrene and other thermoplastic resins, used for packaging, and used as film coatings. Plastic packages and plastic package products have a growing share in the market, and particularly, composite plastic flexible packages have been widely applied to the fields of food, medicine, chemical industry and the like, wherein the proportion of the plastic packages is the largest, such as beverage packages, quick-frozen food packages, steamed and cooked food packages, fast food packages and the like, and the plastic packages and the plastic package products bring great convenience to the life of people. The plastic films in the present day are mainly classified into a PVA coated high barrier film, a biaxially oriented polypropylene film (BOPP), a low density polyethylene film (LDPE), a polyester film (PET), a nylon film (PA), a cast polypropylene film (CPP), an aluminum plated film, and the like.
However, after the plastic film is used for outer packaging of the product, the sealing performance is good, so that if the humidity of the product is high or the product contains a lot of moisture, the moisture is difficult to be discharged through the plastic film, so that the moisture between the plastic film and the product is high, and the phenomenon of deterioration or corrosion is easy to occur after a long time, and the resource waste is caused.
SUMMERY OF THE UTILITY MODEL
Technical problem to be solved
Aiming at the defects of the prior art, the utility model provides a moisture-absorbing and moisture-proof plastic film for packaging, which can effectively absorb excessive moisture on a product.
(II) technical scheme
In order to achieve the purpose, the utility model provides the following technical scheme: the utility model provides a moisture absorption dampproofing plastic film for packing, includes the plastic film, the plastic film includes the base film, the bottom of base film is provided with the ventilated membrane, be provided with the several piece that absorbs moisture between ventilated membrane and the base film.
Furthermore, a plurality of through holes are formed in the breathable film and are uniformly distributed.
Still further, the absorbent mass is composed of a plurality of absorbent particles.
Preferably, a plurality of the moisture absorption blocks are uniformly arranged.
(III) advantageous effects
Compared with the prior art, the utility model provides a moisture absorption and moisture prevention plastic film for packaging, which has the following beneficial effects:
this a moisture absorption moisture proof plastic film for packing adsorbs through the moisture absorption piece to the moisture between product and the plastic film, makes this plastic film have good moisture absorption effect, can effectual absorption product go up unnecessary moisture, makes and keeps dry between product and the plastic film.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic structural view of the present invention in use.
In the figure: 1. a base film; 2. a gas permeable membrane; 3. a moisture-absorbing block; 4. and a through hole.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1-2, the moisture absorption and moisture proof plastic film for packaging of the present invention comprises a plastic film, the plastic film comprises a base film 1, the material of the base film 1 is the main material of the plastic film, and can be selected according to different packaging purposes, the bottom end of the base film 1 is provided with a breathable film 2, the breathable film 2 is directly contacted with a product, the material can be selected according to different products, a plurality of moisture absorption blocks 3 are arranged between the breathable film 2 and the base film 1, the moisture absorption blocks 3 absorb moisture between the product and the plastic film, the breathable film 2 is provided with a plurality of through holes 4, and the plurality of through holes 4 are uniformly distributed, the breathable film 2 fixes the moisture absorption blocks 3 between the breathable film 2 and the base film 1, the through holes 4 are arranged to enable the moisture between the plastic film and the product to be absorbed by the moisture absorption blocks 3 through the through holes 4, the moisture absorption blocks 3 are composed of a plurality of moisture absorption particles, the plurality of moisture absorption particles are divided into two types, namely a plurality of silica gel particles and a plurality of alumina particles, the moisture absorption blocks 3 absorb moisture in a physical moisture absorption mode, and the plurality of moisture absorption blocks 3 are uniformly arranged, so that the moisture absorption effect of the plastic film is more uniform.
To sum up, when the moisture absorption and moisture prevention plastic film for packaging is used, the plastic film with a proper size is taken firstly, then one surface of the breathable film 2 of the plastic film faces to a product, the product is wrapped, and the redundant part of the plastic film is removed.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
