Abstract
A polyethylene heavy packaging film composite can be widely used for producing blisterpack, such as FFS package, large goods package, tray package and so on, which can effectively improve the all round performance of packaging film, and make the package of goods more beauty, firm, green and effective. The film composite comprises: linear low density polyethylene accounting for 60-80% of the sum of the material, low density polyethylene accounting for 5-25% of the sum of the material, metallocene linear low density polyethylene accounting for 10-30% of the sum of the material, additive accounting for 3-7% of the sum of the material. An automatic feed proportioning system feeds the material of three extruders to die head and the heavy packaging film combination is obtained after three-layer extruding and mixing. The additive is combination of one or several kinds of slippery agent, antistatic agent, antioxidant, opening agent, thermal stabilizer.
Description
Technical field
The present invention relates to a kind of polyethylene (PE) repackaging film material composition.Belong to plastics processing and application technology.
Background technology
Heavy duty packaging film is the domestic a kind of new packaging material that grew up in recent years, is that a kind of continuity automatic moulding, opening can realized fills the novel package film product that material, heating such as seal at multiple working procedure and operation process.Can satisfy the needs of the high speed filling of scale operation automatic packaging line, large-scale accumulating and automatic stacking, not only improved packaging efficiency greatly, and the simplification of bag operation, only need coextrusion blow, (online or off-line) printing, envelope cutting bag, greatly reduce the comprehensively packaging cost.Traditional compound braided bag packing must be drenched through plastics film blowing, wire drawing, plastics and be answered (pouring film), prints, cuts, seals a series of complicated step such as cutting bag, and production efficiency is low, the capacity packing of wall scroll pack-thread is limited in below 500 bags/hour usually, and use heavy duty packaging film pack-thread, capacity packing can reach 1700～1900 bags/hour usually, and obviously traditional compound braided bag packing can not satisfy the needs of modernized high-speed packaging.At present, in developed countries such as Europe, heavy duty packaging film has become general heavy wrapping material, this novel heavy wrapping material not only can satisfy the needs of industrial chemicals product modernization packing, and the packing of agricultural byproducts such as rice, soybean, agricultural chemicals, chemical fertilizer, daily chemical product is also had broad application prospects.
Because novel heavy duty packaging film product is from just trial production at home just of calendar year 2001, still be at present the starting stage of application, its product quality indicator does not form unified national standard yet, only is by consulting to determine with the form of contract between each user and the supplier with reference to foreign standard.The prescription of product is also immature, still be in update and improve among, directly cause the quality fluctuation of product bigger, particularly the tensile strength of product and puncture resistance are very unstable, multiple accidents such as inclusion breaks, heat seal strength deficiency often take place, and have had a strong impact on the ordinary production of automatic packaging line.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of polyethylene repackaging film material composition, can improve the performance of heavy duty packaging film effectively, solve the defective of above-mentioned existence, possess advantages such as cost is low, high efficiency, intensity height, puncture resistance excellence simultaneously, and working mechanism is simple, suitability is extensive, and result of use is remarkable.
Technical scheme: the present invention to the optimization improvement of multilayer packing membrane material formula, adds multiple additives according to concrete purposes by the research to the PE repackaging film material again, obtains a kind of PE repackaging film material composition.
This coating materials composition comprises linear low density polyethylene, new LDPE (film grade), metallocene linear-low density polyethylene, additive, wherein, linear low density polyethylene is selected hexene or the octene high ' alpha ' olefin product as comonomer for use, accounts for 60～80% of raw material total amount by mass ratio; New LDPE (film grade) accounts for 5～25% of raw material total amount by mass ratio; Metallocene linear-low density polyethylene accounts for 10%～30% of raw material total amount by mass ratio; Additive accounts for 3～7% of raw material total amount by mass ratio; By the quality feed proportioning system, deliver to die head with adding three forcing machines respectively behind linear low density polyethylene, new LDPE (film grade), the metallocene linear-low density polyethylene adding additive, carry out obtaining polyethylene repackaging film material composition after the three-layer co-extruded mixing.Additive is one or more the combination in slipping agent, static inhibitor, oxidation inhibitor, opening agent, the thermo-stabilizer.
Beneficial effect: compared with prior art, PE repackaging film material composition of the present invention can be widely used in the production in heavy duty packaging film field, as FFS bag packing, large cargo packing, pallet packing etc., can not only significantly improve the intensity and the puncture resistance of packaging film, the film transverse tensile strength is greater than 28Mpa, longitudinal tensile strength is greater than 30Mpa, and the dart impact strength on two sides is greater than 800g, and make the packing of kinds of goods more attractive in appearance, firm, energy-conservation and efficient.
The main performance index of heavy duty packaging film product and testing standard
