Abstract
The utility model discloses a packaging film with drying function mainly comprises polyester layer, dry layer, non -woven fabrics layer, curtain coating polypropylene layer and chitosan layer, dry layer uses the non -woven fabrics layer as the carrier, and polyester layer and curtain coating polypropylene layer separate application provide good waterproof performance and gas tightness in the interior outside on non -woven fabrics layer, polyester layer, can prevent the entering of outside moisture, chitosan layer coats the inboard on curtain coating polypropylene layer, and chitosan layer is the polysaccharide structure, the utility model discloses rational in infrastructure, low in production cost not only provides good gas tightness and waterproof nature, simultaneously can also the inside moisture of effectual absorption wrapping bag to especially adapted dry fruit packing of product, whole moreover still have fine biodegradability, little to the environmental disruption.
Description
Technical field
This utility model relates to one in a big way, a kind of packaging film with functions/drying.
Background technology
Packaging film is mainly formed by the mixed with resin extrusion of several different trades mark, there is puncture resistant, super-strength high-performance, the goods being deposited on supporting plate is wound packaging, make packing material more firm clean and tidy, more superpower waterproof action, is widely used in foreign export, papermaking, five metals, plastics chemical industry, building materials, food pharmaceuticals industry.
For the packaging film of dry fruit, do not need only have extraordinary waterproof effect, it is also required to have drying effect simultaneously, under normal circumstances, need to place one bag of desiccant during dry fruit packaging, not only increase production process and cost, and the most unsightly, and the function that existing food package film is so dried.
Summary of the invention
The purpose of this utility model is to provide a kind of packaging film with functions/drying, with the problem solving to propose in above-mentioned background technology.
For achieving the above object, the following technical scheme of this utility model offer:
A kind of packaging film with functions/drying, mainly it is made up of polyester layer, drying layer, nonwoven layer, cast polypropylene layer and chitosan layer, described drying layer is with nonwoven layer as carrier, polyester layer and cast polypropylene layer are respectively coated the interior outside in nonwoven layer, polyester layer provides good water resistance and air-tightness, is possible to prevent the entrance of outside moisture；Described chitosan layer coats the inner side of cast polypropylene layer, and chitosan layer is polysaccharide structures, can not only provide fresh-keeping function, has preferable degradation capability, environmentally safe simultaneously, utilizes drying layer to realize being dried inner air simultaneously.
As further program of the utility model: described drying layer is made up of calcium silicates powder or calcium chloride powder.
As this utility model further scheme: the thickness of described polyester layer is 18 μm-20 μm, the thickness of nonwoven layer is 90 μm-150 μm, and the thickness of cast polypropylene layer is 20 μm-40 μm, and the thickness of chitosan layer is 13 μm-17 μm.
Compared with prior art, the beneficial effects of the utility model are: this utility model is rational in infrastructure, production cost is low, good air-tightness and water proofing property are not only provided, can also effectively absorb packaging bag internal moisture simultaneously, thus it is especially suitable for the packaging of dried fruit product, and entirety also has good degradation capability, and little to environmental disruption.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of packaging film with functions/drying of this utility model.
In figure: 1-polyester layer, 2-drying layer, 3-nonwoven layer, 4-cast polypropylene layer, 5-chitosan layer.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model rather than whole embodiments.Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art are obtained under not making creative work premise, broadly fall into the scope of this utility model protection.
Refer to Fig. 1, in this utility model embodiment, a kind of packaging film with functions/drying, mainly it is made up of polyester layer 1, drying layer 2, nonwoven layer 3, cast polypropylene layer 4 and chitosan layer 5, described drying layer 2 is with nonwoven layer 3 as carrier, polyester layer 1 and cast polypropylene layer 4 are respectively coated the interior outside in nonwoven layer 3, and polyester layer 1 provides good water resistance and air-tightness, is possible to prevent the entrance of outside moisture；Described chitosan layer 5 coats the inner side of cast polypropylene layer 4, and chitosan layer 5 is polysaccharide structures, can not only provide fresh-keeping function, has preferable degradation capability, environmentally safe simultaneously, utilizes drying layer 2 to realize inner air simultaneously and is dried.
Described drying layer 2 is made up of calcium silicates powder or calcium chloride powder.
The thickness of described polyester layer 1 is 18 μm-20 μm, and the thickness of nonwoven layer 3 is 90 μm-150 μm, and the thickness of cast polypropylene layer 4 is 20 μm-40 μm, and the thickness of chitosan layer 5 is 13 μm-17 μm.
Operation principle of the present utility model is: polyester layer 1 provides good water resistance and air-tightness, it is possible to prevent the entrance of outside moisture, chitosan layer 5 coats the inner side of cast polypropylene layer 4, chitosan layer 5 is polysaccharide structures, fresh-keeping function can not only be provided, there is preferable degradation capability simultaneously, environmentally safe, utilize drying layer 2 to realize inner air to be dried, drying layer 2 can help to siphon away packaging bag internal moisture, thus play desiccation, and need not place extra desiccant.
It is obvious to a person skilled in the art that this utility model is not limited to the details of above-mentioned one exemplary embodiment, and in the case of without departing substantially from spirit or essential attributes of the present utility model, it is possible to realize this utility model in other specific forms.Therefore, no matter from the point of view of which point, embodiment all should be regarded as exemplary, and be nonrestrictive, scope of the present utility model is limited by claims rather than described above, it is intended that all changes fallen in the implication of equivalency and scope of claim included in this utility model.Should not be considered as limiting involved claim by any reference in claim.
In addition, it is to be understood that, although this specification is been described by according to embodiment, but the most each embodiment only comprises an independent technical scheme, this narrating mode of description is only for clarity sake, description should can also be formed, through appropriately combined, other embodiments that it will be appreciated by those skilled in the art that as an entirety, the technical scheme in each embodiment by those skilled in the art.
