Multi-layer wear-resistant plastic packaging bag
Technical field
The present invention relates to plastics package, particularly relate to a kind of multi-layer wear-resistant plastic packaging bag.
Background technology
Plastics are to synthesize or natural macromolecule resin is main material. Add after various auxiliary agents, under certain temperature and pressure, be ductile, can fix a class material of its shape after cooling. Natural or synthetic macromolecule resin molecule is under molten condition, and the process of the auxiliary agent molecule that around distributes is uniformly plasticizing, has reached this process having plastified, and does not also reach, and is considered to not yet plastify. Plastics package is one of four large materials in packing business: paper and cardboard account for 30%, and plastics account for 25%, and metal accounts for 25%, and glass accounts for 15%. The most material of existing polybag and structure are comparatively simple, very easily damage, and owing to adopting multiple additives composition to make when use, cannot storing food, avoid affecting health, quite inconvenience when use.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of multi-layer wear-resistant plastic packaging bag, this multi-layer wear-resistant plastic packaging bag contributes to the permanent use of packaging bag can not damage, and production cost is low, and internal layer adopts polydiphenyl ether plastics to make, nontoxic anti-pollution, result of use is good.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of multi-layer wear-resistant plastic packaging bag is provided, comprise the environmental protection layer of internal layer, middle packed layer and surperficial wearing layer, the environmental protection layer of described internal layer is made up of polydiphenyl ether plastics, the packed layer of described centre is made up of talcum powder, the wearing layer on described top layer is made up of Fypro plastics and age resistor, plasticizer and Nucleating Agent, described age resistor is p-phenylenediamine (PPD), described plasticizer is phthalic acid two (2-ethyl hexyl) ester, and described Nucleating Agent is zirconium dioxide.
In a preferred embodiment of the present invention, in described wearing layer, the shared percentage by weight of each composition is respectively described Fypro plastics and accounts for 92.1%-94.7%, described benzene two ammoniums are accounted for to 2.4%-3.3%, described phthalic acid two (2-ethyl hexyl) ester accounts for 1.6%-2.5%, and described zirconium dioxide accounts for 1.3%-2.1%.
In a preferred embodiment of the present invention, in described wearing layer, the shared percentage by weight of each composition is specially described Fypro plastics and accounts for 94.4%, described benzene two ammoniums are accounted for to 2.5%, described phthalic acid two (2-ethyl hexyl) ester accounts for 1.7%, and described zirconium dioxide accounts for 1.4%.
In a preferred embodiment of the present invention, in described wearing layer, the shared percentage by weight of each composition is specially described Fypro plastics and accounts for 92.5%, described benzene two ammoniums are accounted for to 3.2%, described phthalic acid two (2-ethyl hexyl) ester accounts for 2.4%, and described zirconium dioxide accounts for 1.9%.
In a preferred embodiment of the present invention, the thickness of described environmental protection layer is 0.1-0.3mm, and the thickness of described packed layer is 0.4-0.8mm, and the thickness of described wearing layer is 0.2-0.5mm.
The invention has the beneficial effects as follows: the present invention contributes to the permanent use of packaging bag can not damage, and production cost is low, internal layer adopts polydiphenyl ether plastics to make, nontoxic anti-pollution, and result of use is good.
Detailed description of the invention
Fig. 1 is the cutaway view in multi-layer wear-resistant plastic packaging bag one preferred embodiment of the present invention;
In accompanying drawing, each mark is as follows: 1, environmental protection layer, 2, packed layer, 3, wearing layer.
Detailed description of the invention
To the technical scheme in the embodiment of the present invention be clearly and completely described below, obviously, described embodiment is only a part of embodiment of the present invention, instead of whole embodiment. Based on the embodiment in the present invention, those of ordinary skill in the art, not making all other embodiment that obtain under creative work prerequisite, belong to the scope of protection of the invention.
A kind of multi-layer wear-resistant plastic packaging bag, as shown in Figure 1, comprise the environmental protection layer 1 of internal layer, middle packed layer 2 and surperficial wearing layer 3, the environmental protection layer 1 of described internal layer is made up of polydiphenyl ether plastics, packed layer 2 talcum powder of described centre form, and the wearing layer 3 on described top layer is made up of Fypro plastics and age resistor, plasticizer and Nucleating Agent, and described age resistor is p-phenylenediamine (PPD), described plasticizer is phthalic acid two (2-ethyl hexyl) ester, and described Nucleating Agent is zirconium dioxide.
Further, in described wearing layer 3, the shared percentage by weight of each composition is respectively described Fypro plastics and accounts for 92.1%-94.7%, described benzene two ammoniums are accounted for to 2.4%-3.3%, described phthalic acid two (2-ethyl hexyl) ester accounts for 1.6%-2.5%, and described zirconium dioxide accounts for 1.3%-2.1%.
Further, in described wearing layer 3, the shared percentage by weight of each composition is specially described Fypro plastics and accounts for 94.4%, described benzene two ammoniums is accounted for to 2.5%, and described phthalic acid two (2-ethyl hexyl) ester accounts for 1.7%, and described zirconium dioxide accounts for 1.4%.
Further, in described wearing layer 3, the shared percentage by weight of each composition is specially described Fypro plastics and accounts for 92.5%, described benzene two ammoniums is accounted for to 3.2%, and described phthalic acid two (2-ethyl hexyl) ester accounts for 2.4%, and described zirconium dioxide accounts for 1.9%.
Further, the thickness of described environmental protection layer 1 is 0.1-0.3mm, and the thickness of described packed layer 2 is 0.4-0.8mm, and the thickness of described wearing layer 3 is 0.2-0.5mm.
The beneficial effect of multi-layer wear-resistant plastic packaging bag of the present invention is: the present invention contributes to the permanent use of packaging bag can not damage, and production cost is low, and internal layer adopts polydiphenyl ether plastics to make, nontoxic anti-pollution, and result of use is good.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes description of the present invention to do; or be directly or indirectly used in other relevant technical field, be all in like manner included in scope of patent protection of the present invention.
