Abstract
The invention relates to an antifog thinned high-toughness heat shrinkable packaging color film. The antifog thinned high-toughness heat shrinkable packaging color film is composed of an upper layer, a middle layer and a lower layer. The upper layer and the lower layer are both made of a mixture containing metallocene MPE, LDPE, LLDPE and an additive; and the middle layer is made of a mixture containing LDPE, MDPE and HDPE. As the upper layer and the lower layer have a high metallocene content, the purpose of thinning by 20% has no influence to the mechanical properties of the film. The additive is a mixture of a lubricant, a plasticizer and an antifogging agent. The antifogging agent enables no formation of water mist after freezing of the product, thus increasing the optical properties and exhibition effect of the film. The middle layer employs about 40% medium density MDPE, and under the premise of ensuring the rigidity, the mechanical properties and optical properties of the film are increased. In general, under the premise of ensuring normal use, the raw material consumption is reduced, and consequently the production cost is reduced.
Description
Technical field:
The present invention relates to a kind of heat shrink films, particularly the color film of a kind of antifog attenuate high-toughness hot shrink wrapping.
Background technology:
As packaging material common in daily life, the application of the color film of heat shrinkable package is very extensive, as long as the products such as beverage, mineral water, tealeaves, beer, milk, cosmetics of everyday use, articles for washing, oil product, food and medicine have carrier to need parcel, can see the figure of the color film of heat shrinkable package.Because multiple separate carrier have been shrunk to an entirety by a skim, its intensity is good, toughness is large, outward appearance is beautiful; Again because shrink film raw material itself are nontoxic, easily brokenly unlike PVC film easily split, and containing poisonous, can sensitive paper case do not make moist after jolting yet and will produce distortion, be therefore subject to increasing pursuing of factory both at home and abroad.
Due to the restriction of raw material and processing technology, the color film of existing heat shrinkable package exists that thickness is thicker and inhomogeneous, impact strength and tear resistance is lower, poor transparency, heat-sealing are bad and freezing after have the technical problems such as water smoke.
Summary of the invention:
The present invention is in order to overcome defect in above-mentioned prior art, provide that a kind of impact strength and tearing toughness are high, transparency and heat-sealing well, the color film of antifog attenuate high-toughness hot shrink wrapping of Thickness Ratio packaging of the same race thin 20%.
In order to realize the above object, according to the invention provides one
The color film of antifog attenuate high-toughness hot shrink wrapping, is made up of the upper, middle and lower; It is characterized in that: described the upper and lower are the mixture that contains metallocene MPE, LDPE, LLDPE and auxiliary agent, its weight proportion is: MPE3-5 part that melt index is 1, melt index is LDPE3-4 part of 0.3, LLDPE2-3 part that melt index is 0.8, auxiliary agent 0.1-0.3 part; Described middle level is the mixture that contains LDPE, MDPE and HDPE, and its weight proportion is: LDPE4-5 part that melt index is 0.3, MDPE2-4 part that melt index is 0.3-0.5, HDPE1-4 part that melt index is 0.8.
In technique scheme, described auxiliary agent is the mixture that contains lubricant, plasticizer and antifoggant.
Compared with prior art, the present invention has following beneficial effect:
Adopt upper, middle and lower-ranking structure, wherein the upper and lower are the mixture that comprises metallocene MPE, LDPE, LLDPE and auxiliary agent, film tear-proof in the situation that of attenuate 20% is impacted for this and anti-drop intensity can not reduce also can increase on the contrary, and its optical property is better; In auxiliary agent, add antifoggant, can effectively prevent that product from not having water smoke to form after freezing, thereby increase the optical and bandwagon effect of film; Middle level is the mixture that contains LDPE, MDPE and HDPE, further improves the rigidity of film, stops to occur bale broken phenomenon in transport and handling process.
Detailed description of the invention:
In order to deepen the understanding of the present invention, below a specific embodiment of the present invention is described in detail, but is to be understood that protection scope of the present invention is not subject to the restriction of detailed description of the invention.It will be appreciated that, mentioned in following embodiment of the present invention " on ", D score, " left side ", " right side ", " front " and " reverse side ", these words that are used for limiting direction are only used to be convenient to explanation, do not represent the restriction to the concrete technical scheme of the present invention.
The color film of antifog attenuate high-toughness hot shrink wrapping, is made up of the upper, middle and lower; Described the upper and lower are the mixture that contains metallocene MPE, LDPE, LLDPE and auxiliary agent, its weight proportion is: MPE3-5 part that melt index is 1, melt index is LDPE3-4 part of 0.3, LLDPE2-3 part that melt index is 0.8, auxiliary agent 0.1-0.3 part; Described middle level is the mixture that contains LDPE, MDPE and HDPE, and its weight proportion is: LDPE4-5 part that melt index is 0.3, MDPE2-4 part that melt index is 0.3-0.5, HDPE1-4 part that melt index is 0.8.Auxiliary agent is the mixture that contains lubricant, plasticizer and antifoggant.
Because the metallocene content using in the upper and lower is high, so under the object of attenuate 20%, can not impact the mechanical property of film, the antifoggant in levels can make product not have water smoke to form after freezing, thereby has increased the optical and bandwagon effect of film.Middle level is used the middle density MDPE of 40% left and right, is ensureing, under the prerequisite of rigidity, to have increased again mechanical property and the optical property of film.Generally speaking, under the normal prerequisite using of guarantee, reduced the use amount of raw material, thereby reduced production cost.
After tested, the color film of antifog attenuate heat shrinkable package of this project does not have water smoke to form after freezing, light transmittance reaches more than 90%, vertically and horizontally stretching intensity >=38mpa, elongation at break >=900% in length and breadth, after packaging product, 1.5 meters are highly freely fallen for several times not bale broken, skin-friction coefficient >=0.3, not landing in transit, heat sealability is good, sealing-strength >20N.
The color film of antifog attenuate high-toughness hot shrink wrapping provided by the invention, has good transparency, fall strength of briquette, surface characteristic and good bandwagon effect.
Disclosed is above only specific embodiments of the invention, and still, the present invention is not limited thereto, and the changes that any person skilled in the art can think of all should fall into protection scope of the present invention.
