Abstract
The utility model relates to a metal volatile corrosion inhibition POF (Polyolefin) heat shrinkable film. The metal volatile corrosion inhibition POF heat shrinkable film comprises a plastic film, which is obtained by compounding three films, wherein an inner layer is VCI (Volatile Corrosion Inhibitor) volatile corrosion inhibition and copolymerized PP (Polypropylene) layer; a middle layer is a linear puncture resistant barrier layer; an outer layer is an ultraviolet resistant copolymerized PP layer; and thickness ratio of the three layers is 1.2:1:1. The metal volatile corrosion inhibition POF heat shrinkable film provided by the utility model has the advantage that corrosion inhibition, sealed, heat insulating, fading slowing packaging protection can be provided for metal products and metal and nonmetal combined products.
Description
Technical field
The utility model relates to packaging material, is specifically related to metal volatile rust prevention POF heat shrink films (bidirection stretching polyolefine shrink film).
Background technology
Show the antirust most employing spray antirust agent of metal object, be coated with modes such as antirust oil, bag anti-tarnish paper, its integrated cost is high, and human resources consumption is big, and enterprise staff health is had certain influence, also can pollute environment.Prior art also has and adopts antirust bag packing, but existing antirust bag light transmittance is low, simultaneously non-metallic part in the product is not had protective effect, also can impact color etc.
Summary of the invention
The purpose of the utility model is to provide for metal, metal and the nonmetal product that combines a kind of antirust, uvioresistant, airtight of better effect, and is heat insulation, slow down the volatile rust prevention copolymerization POF heat shrink films of the protection of fading.
The solution of the utility model is following:
A kind of volatile rust prevention copolymerization POF heat shrink films, it is by the compound plastic sheeting that constitutes of trilamellar membrane.Wherein, internal layer is VCI (vapour phase inhibitor, Volatile Corrosion Inhibitor) volatile rust prevention and a copolymerization PP shrink wrap layer, and the intermediate layer is linear anti-puncture barrier layer, and skin is a uvioresistant copolymerization PP shrink wrap layer; Three layers thickness is than being 1.2:1:1.
The utility model adopts unique three-decker, has the following advantages:
1, superior performance: This POF shrink film preclude the use of multi-layer extrusion technology to produce blends, inner layer copolymer PP material, because of its high transparency, good gloss, appearance of the product can be clearly demonstrated to improve sensory awareness, reflect the high grade.Also have very greatly in length and breadth to shrinkage factor, reach as high as 75%, pliability is good, can pack the commodity of any profile, and, its cold resistance can keep pliabilities and embrittlement not take place at-50 ℃, is fit to the pack metal object and under cold environment, stores and transport.Environment-protecting asepsis, processing and use health are nontoxic, meet U.S. FDA and USDA standard, and can closely encase on the metallic object, and secluding air increases seal.The VCI gas molecule in space fully is kept at wherein and is slowly discharged; Because the middle level intercepts can not be to external diffusion; The POF heat shrink films does not discharge when having the contacting metal product, just begins to discharge the VCI gas molecule in space and be enclosed in product surface the protection product when having only contact product.And the excellent anti-puncture function of the copolymerization PP of internal layer can guarantee that barrier layer is not destroyed when the packing of product of corner angle is arranged, and gas molecule in space can be to external diffusion.Outer field anti-ultraviolet function can stop ultraviolet ray to the irradiation of product and heat insulation; Stop the variable color of metal product specular surface; Slowing down metal fades with the nonmetal product non-metallic part that combines; Stop two kinds of storeroom thermal deformations, the anti-puncture function that outer field copolymerization PP is excellent can stop external force that middle level and internal layer are destroyed to lose effect.
2, it is strong to seal ability up for safekeeping: the extremely strong anti-puncture function of the VCI volatile rust prevention of internal layer and copolymerization PP combines with outer field uvioresistant and the excellent anti-puncture function of copolymerization PP; Make product under household condition also can reach 3-6, as seal and better can reach fully more than 10 years and can guarantee that color is gorgeous as new.
3, attractive in appearance, environmental protection: owing to adopt the three-layer plastic structure, transparency is high, can observe product fully after heat shrinkable package is good.Need not be coated with any grease and antirust agent before the packing of product, need not clean behind the disassemble heat shrinkable package, can not cause any pollution to environment, heat shrinkable package also can recycling.
This heat shrink films mainly applies to metal rust preventing, the anti-variable color in high brightness alloy material surface, metal and nonmetal combination product non-metallic part and fades.The heat shrink films packing of different size be can process according to the product size size, automobile, boats and ships, machinery, military project, electronic applications are applicable to.Along with China adds World Trade Organization; A large amount of products constantly exports to abroad; Transportation for a long time, moist marine climate, long-term ultraviolet ray are shone increasingly high to the product requirement of shelter; Some big machinery parts particularly, automobile, large-scale coil of strip section bar etc. is just needing this kind heat shrink films manner of packing.
Description of drawings
Fig. 1 is the cross-sectional view of this heat shrink films.
The specific embodiment
This heat shrink films is formed by trilamellar membrane is compound, and referring to Fig. 1, internal layer is volatile rust prevention and copolymerization PP shrink wrap layer 3, by 10%VCI volatile rust prevention inhibition material, 90% high strength TPP (ternary polymerized polypropylene), PPC (binary copolymerization polypropylene) material blend; The intermediate layer is linear anti-puncture barrier layer 2, is the high barrier material with 50%, 2% compatilizer and PEF blend; Outer for the anti-puncture layer 1 of uvioresistant, be with 95% high-intensity TPP (ternary polymerized polypropylene), PPC (binary copolymerization polypropylene) material, 0.5% anti ultraviolet agent blend; Three layers thickness adopts film extrusion than outer 1.2:1:1.
The utility model can adopt the three-layer co-extruded equipment of present technological comparative maturity, and compatible properties between utilization PEF and copolymerization polypropylene raw material adopts blend expressing technique blown film.The thermal contraction film body is followed successively by the anti-puncture layer of volatile rust prevention copolymerization PP shrink wrap layer, high-barrier, uvioresistant copolymerization PP shrink wrap layer from inside to outside, extrudes under the effect of middle level adhesive layer perfect adaptation and gives full play to its effect through head is compound for these three layers.
