The product of the present invention has high transparency, and may be used in printing bright pattern and packing with stable stacking and is suitable for mechanical production. The product of the present invention may be used in packing various products, such as farm product, domestic article, cosmetic, detergent, food, medicine, beverage, etc.
Description
Technical field
The present invention relates to polyethylene heat-shrinkable film and production method thereof, particularly high-clarity polyethylene heat-shrinkable film and production method thereof belong to plastics, field of packaging material.
Background technology
The packing of commodity for the storage of commodity, guarantee the quality, beautify and have vital role.Along with development of market economy, people are more and more higher for the requirement of commodity packaging, the wrapping material of multiple novelty also occurred.
In industries such as food, medicine, beverages, traditional outer packaging form is packed in cases, and the carton moistureproofness is poor, and packing material is mouldy easily, is unable to undergo extruding, and transportation stores inconvenient; Consumption of natural resource is unfavorable for environmental protection.The cost of packed in cases is higher, and required manually more, if adopt the mechanize form of packing automatically, the investment of its equipment will be higher.The outer packaging form that the bottled beer industry is traditional is an enlacement packaging, and this packaged form spends much more artificial and is absolutely unsafe, and causes bottle explosion easily.
Along with economic growth, high-tech development, the making rapid progress of product, people's life more tends to convenient and leisure, and the packing of product has been had higher requirement.Based on the defective of above two kinds of packaged forms, people begin to adopt the packing with the polyethylene heat-shrinkable film to replace traditional packed in cases and enlacement packaging.Heat-shrinkable film has unique advantage as wrapping material: economical with materials, reduce cost, protection against the tide, health, easy to use; Commodity after the packing are attractive in appearance, conserve space.The commodity of heat-shrinkable film packing can be accomplished " fit " packing, make commodity have distinguished outward appearance; The technology of the package of heat-shrinkable film is also simple especially, as long as just can finish wrapping process to its heating, has improved the packing production rate.
The polyethylene heat-shrinkable film is that application is more a kind of in the heat-shrinkable film, because polyethylene is considered to non-toxic material, is particularly suitable for the commodity packaging of industries such as food, medicine, beverage.
But in the commodity of industries such as food, medicine, beverage, bottle class commodity have significant proportion, and the polyethylene heat-shrinkable film runs into challenge to the packing of this bottle class commodity.There is following defective in common polyethylene heat-shrinkable film:
1, the heat-sealing temperature of Xu Yaoing is too high, not only can influence the outward appearance of the outer PVC label of bottle, even also can influence the quality of the interior article (as beverage or beer etc.) of bottle of packaging.
2, smooth surface, the stacking instability is transported dangerous.
3, grow dim or turn white in the surface, and when needs printed on heat-shrinkable film, effect was not beautiful.
4, insufficient strength, the weight that can bear is not enough.
Summary of the invention
The invention provides a kind of high-clarity polyethylene heat-shrinkable film, can effectively overcome the above-mentioned defective that at present common polyethylene heat-shrinkable film exists.The present invention also provides the production method of this high-clarity polyethylene heat-shrinkable film.
Metallocene is the Organometallic complexes that the undersaturated luxuriant ring of transition metal and ring-type (promptly encircling luxuriant diene) is formed.Metallocene-polyolefin promptly is to be that catalyzer carries out the prepared polymkeric substance of olefinic polyreaction with metallocene coordination compound (metallocene), the characteristics of metallocene catalyst are that the active centre is single, active identical, can prepare molecular weight distribution very narrow and the height stereoregular polymkeric substance, to polymericular weight, molecular weight distribution, the stereoregular structure, co-monomer content and distribution, can realize accurate control, thereby produce the polyolefin resin of excellent performance, can give polymkeric substance with good physicals and processing characteristics, mainly contain MpE at present, Mpp, Mps etc.
Metallocene polymers has good, and the excellent properties such as the transparency is good of good processability, high fondant-strength, high rigidity, thin film stability, thereby receive people's very big concern, and therefore released many new products, be applicable to aspects such as food product pack, medical packaging, shrinkable film and sanitary product.
It is the polyethylene that polymerizing catalyst is produced that metallocene PE is to use metallocene.Compare metallocene polyethylene film toughness height, puncture intensity height, tear-resistant, low temperature resistant, long service life with other polyethylene films.Be widely used in pack for liquids, detergent bag, salt bag, rice bag, twine film, modification basic material, medical apparatus and drug packaging etc.
High-clarity polyethylene heat-shrinkable film provided by the invention, prepare burden by comprising the mixture that metallocene LDPE (new LDPE (film grade)), linear LDPE, LDPE and auxiliary agent are formed, stirrer stirs, mixes, and compound is extruded through forcing machine, and heat-shrinkable film is made in blow molding.
The mixture of preparing burden the ratio of each component is: metallocene LDPE 4-6 weight part, linear LDPE 1-2 weight part, LDPE 2-3 weight part, auxiliary agent 0.2-0.4 weight part.
Described forcing machine can be a single screw extrusion machine, and the processing temperature of extrusion-blown modling can be made heat-shrinkable film at 160-200 ℃.
Described auxiliary agent can comprise lubricant, softening agent, can also comprise talcum powder or diatomite.
Described lubricant can be for stearic acid or stearic metal-salt, as calcium stearate, Magnesium Stearate and barium stearate etc.; Described softening agent can be polyvalent alcohol, as the incomplete esterification products of propylene glycol, glycerol, tetramethylolmethane, sorbyl alcohol or they and longer chain fatty acid such as glyceryl monostearate etc.
This high-clarity polyethylene heat-shrinkable film provided by the invention has improved transparency, intensity, heat sealability and the surface property of polyethylene heat-shrinkable film.
The transmittance of product of the present invention can reach more than 90%, in length and breadth to tensile strength 〉=24mpa, and in length and breadth to elongation at break 〉=700%, skin friction coefficient 〉=0.4, heat sealability is good, sealing-strength 〉=20N.
As a comparison, common polyethylene heat-shrinkable film poor transparency, grow dim or turn white in the surface; In length and breadth to tensile strength 〉=12mpa; Longitudinal fracture elongation 〉=200%; Transverse breakage elongation 〉=250%; Skin friction coefficient 〉=0.2; Heat sealability is general, sealing-strength 〉=10N.
This high-clarity polyethylene heat-shrinkable film provided by the invention has improved the transparency of film, makes whole packing more beautiful and bright-coloured after the printing; Improved the surface property of film, made the packing stacking more stable, transported convenient; Improve the intensity of film, guaranteed to bear the weight of content; Improve the rigidity and the heat sealability of film, adapted to mechanize production, and can improve the rebound resilience of packing; Product has constant in length and breadth to shrinking percentage, can guarantee the stability of packing.
Product of the present invention can be applied on the wrapping material such as Agricultural products, daily necessities, makeup, washing composition, food, medicine, beverage.
In conjunction with the flexographic printing technology that the applicant grasps, high-clarity polyethylene heat-shrinkable film of the present invention also very is suitable as the material of flexible printing, provides a kind of energy to substitute the packaged form of carton.Its not only attractive in appearance, light, health can also improve the speed of packaging production line, reduces cost; Satisfy the requirement to packing when client selects commodity in the modern economy society fully.
