Background technology
Plastic film product is widely used in the fields such as household, building materials, food, medicine, chemical industry, for various product
Packaging, storage and transport, can play a good protection.Tack film is because have the use that can reduce adhesive
Conveniently tear open so as to reducing artificial and technological process during packaging, reducing pollution, packaging film that adhesive is likely to result in product
Except the features such as, which applies increasingly extensive.Modern packaging industry packs requirement of the popularity of product to packing film also more and more higher,
The combination properties such as tack, intensity, toughness, paracentesis resistance, wholesomeness, good outward appearance and the transparency to film product are carried
Higher requirement is gone out.
Market packaging film is often because of some performance deficiencies at present, it is impossible to meet wider application demand, prepares combination property good
Packing film be modern packaging industry pressing needs.
The content of the invention
For the deficiencies in the prior art, it is an object of the invention to provide a kind of high intensity puncture-resistant adhesive protecting film, phase between each layer
Capacitive is good, caking property is high, and obtained film tack is high, with high intensity, paracentesis resistance and excellent optical transparence.
High intensity puncture-resistant adhesive protecting film of the present invention, is obtained by three-layer co-extruded blown film, and internal layer is by mLLDPE and EVA
Mixing is obtained, and intermediate layer is obtained by mLLDPE and LLDPE mixing, and outer layer is mixed by random impact copolymer polypropylene and LLDPE
Obtain.
Wherein：
Internal layer thickness accounts for the 10-40% of film gross thickness, and intermediate layer thickness accounts for the 20-50% of film gross thickness, and outer layer thickness accounts for film gross thickness
10-40%.
In internal layer, weight ratio shared by EVA is 30-70%, and EVA uses can adjust film tack, and the use of mLLDPE can
The intensity and the transparency of film forming and this layer are adjusted, combination property is optimum under the weight ratio, EVA more preferably weight ratios are
40-60%；In intermediate layer, weight ratio shared by mLLDPE is 10-80%, and the use of the mLLDPE can adjust this layer of film strength
And puncture resistance, shared by mLLDPE, weight is than preferably 50-70%；In outer layer, random weight ratio shared by impact copolymer polypropylene is
30-70%, the use of random impact copolymer polypropylene can adjust the performances such as the stretch-resistance of film, intensity, deflection, and provide
The good transparency of film, shared by random impact copolymer polypropylene, weight is than preferably 50-70%.Three layers of raw material are mixed respectively
High intensity puncture-resistant adhesive protecting film of the present invention can be obtained by multilayer extrusion blown film after even, extrusion blown film temperature is
135-205℃；Between its each layer, caking property is good, and obtained film tack is high, and with high intensity, paracentesis resistance and excellent
The transparency.
Melt mass flow rate (the MFR of mLLDPE used2.16) for 1-30g/10min, density is 0.920-0.940g/cm3,
Molecular weight distribution Mw/MnBetween 2 and 6；Melt mass flow rate (MFR2.16) be preferably 2.5g/10min, density and be preferably
0.925g/cm3。
MLLDPE is that ethene is produced using gas-phase process under metallocene catalyst effect with alpha-olefin, preferred alpha-olefin
Molfraction 2-4%, alpha-olefin be butene-1, hexene -1, octene-1 or tetramethyl amylene -1, preferred hexene -1.
The MFR of random impact copolymer polypropylene is 20g/10min, and random impact copolymer polypropylene is preferably QCT20N, its knot
For random copolymerization and crushing-resistant copolymerization are employed in polymerization simultaneously, performance characteristics are to have high transparent and impact concurrently to structure feature.By
There is in antinoise structure long ethene segment, compatibility and polyethylene between, caking property can be strengthened, improve the strong of packaging film
Degree, and while ensure that the transparency of packaging film.
LLDPE is the LLDPE without auxiliary agents such as opening agent, slipping agents, can be the QLLF20 that Qilu Petrochemical is produced,
But the not limited to this trade mark.
EVA is ethylene-vinyl acetate copolymer, and wherein vinyl acetate weight content is 18-25%.
High intensity puncture-resistant adhesive protecting film of the present invention, is obtained by three-layer co-extruded blown film, and extrusion temperature is 135-205 DEG C.
In sum, the present invention has advantages below：
(1) present invention obtains a kind of high intensity puncture-resistant self-adhesion guarantor by the screening and preparation of three layers of raw material and by coextrusion film blowing
Cuticula, between its each layer, compatibility is good, caking property is high, and obtained film tack is high, with high intensity, paracentesis resistance and excellent
Different optical transparence.
(2) high intensity puncture-resistant adhesive protecting film of the present invention, is obtained by three-layer co-extruded blown film, three layers each provide it is thin
The different performance of film, internal layer are the self-adhesive layer that can improve good tack, and intermediate layer provides stretch-resistance and paracentesis resistance, outer layer
Film strength, deflection etc. are provided, at the same this three layers be respectively provided between good optical transparence, three layers have good compatibility,
Caking property.
(3) its high intensity of high intensity puncture-resistant adhesive protecting film of the present invention and paracentesis resistance can fully meet frozen fish
The packing instructions of shrimp, ice-spur, sharppointed article etc., its good tack disclosure satisfy that modern packaging quick, wholesomeness of industry etc.
