Abstract
The invention relates to a liquid sterile composite package multicolor material and a preparation method thereof. The liquid sterile composite package multicolor material consists of eight layers of materials which sequentially include a low-density polyethylene LDPE layer, a high-toughness all-wood paperboard or a gold paperboard or a silver paperboard or a pearlescent paperboard paper layer, a low-density polyethylene LDPE layer, an ethylene-methacrylic acid multipolymer EMAA layer, an aluminum foil Al layer, an ethylene-methacrylic acid multipolymer EMAA layer, a low-density polyethylene LDPE layer and a metallocene catalyzed linear polyethylene M-LLDPE layer from outside to inside. The preparation method is characterized in that the method comprises the following steps: firstly, compounding low-density polyethylene LDPE and ethylene-methacrylic acid multipolymers EMAA; then, compounding obtained materials with metallocene catalyzed linear polyethylene M-LLDPE; and finally, compounding low-density polyethylene LDPE. The compounding technology adopts a co-extrusion structure, and the natural gas flame processing is adopted when compounding the gold paperboard or the silver paperboard. The invention can solve the problems of performance and cost of the package of liquid beverages in the prior art.
Description
Technical field
The invention belongs to packaging field, particularly relate to a kind of liquid sterile composite package multicolor material and preparation method.
Background technology
The dairy beverage kind is more and more now, and different beverages has the Different Package requirement, therefore, needs a kind of can being extensive use of, and performance is good, and the packing that cost is low adapts to various needs.
In the prior art, the combined type of multilayer material is successively carried out, so the material of sipper pore is damaged easily, and the successively compound technology time is long, and efficient is low.And, more single on the texture in packing, the packaged beverage of metallic luster is seldom arranged, and of low quality, cost is bigger.
Summary of the invention
Technical problem to be solved by this invention provides a kind of liquid sterile composite package multicolor material and preparation method, with the performance that solves liquid drink packing in the prior art, the problem of cost.
The technical solution adopted for the present invention to solve the technical problems is: a kind of liquid sterile composite package multicolor material is provided, be made up of 8 layer materials, described 8 layer materials are composited by low density polyethylene layer, high tenacity whole wood pulp cardboard or gold card paper or silver foil or pearly-lustre paperboard paper layer, low density polyethylene layer, ethylene-methacrylic acid copolymer EMAA layer, aluminium foil Al layer, ethylene-methacrylic acid copolymer EMAA layer, low density polyethylene layer, the hot pressing of metallocene catalysis linear polyethylene M-LLDPE layer from outside to inside successively.
Described metallocene catalysis linear polyethylene M-LLDPE layer component comprises the metallocene of 30%-60%, the polyethylene of 40%-70%.
A kind of method for preparing liquid sterile composite package multicolor material is provided, comprise successively the punching of step cardboard printing, impression, with compound, the extrusion coated hot sealing layer of aluminium foil heat seeling coating, extrusion coated sealer, the layer of 8 layer materials with the compound order of layer is: (1) low density polyethylene layer and ethylene-methacrylic acid copolymer EMAA layer are compound; (2) composite bed of step (1) and metallocene catalysis linear polyethylene M-LLDPE layer are compound; (3) compound other material; (4) last compound outermost low density polyethylene layer.
Described complex technique adopts coextruded structure, promptly extrudes bilayer or trilaminate material simultaneously and carries out compound.
In the described complex technique, adopt Flame of Natural Gas to handle when compound gold card paper or silver card ply of paper, the compound material speed by flame be 400m/min, the temperature of flame treatment is 800 ℃-1000 ℃.
Beneficial effect
The invention enables the characteristics that the aseptic packaging material cost is low, performance is high:
1. the compound order of each material layer of the present invention has been protected the integrality of sipper pore paper the biglyyest;
2. the second layer adopts different materials can reach the packing effect of different color and lusters;
3. complex technique adopts coextruded structure, and the NOT function ergosphere in the centre can adopt raw material at a low price, thereby has reduced cost;
4. adopt Flame of Natural Gas to handle the potential safety hazard of having avoided sided corona treatment to bring, and make gold and silver paperboard and the compound high strength that reaches of polyethylene heat;
5. distinctive 8 layers of paper plastic-aluminum structure, product pliability height is owing to guaranteed that all there is extraordinary binder resin on the aluminium foil both sides, can reach high strength between aluminium foil layer and the plastic layer.
Description of drawings
Fig. 1 is a structure chart of the present invention.
Wherein: 1-low density polyethylene layer, 2-high tenacity whole wood pulp cardboard paper layer, 3-low density polyethylene layer, 4-ethylene-methacrylic acid copolymer EMAA layer, 5-aluminium foil Al layer, 6-ethylene-methacrylic acid copolymer EMAA layer, 7-low density polyethylene layer, 8-metallocene catalysis linear polyethylene M-LLDPE layer.
The specific embodiment
Below in conjunction with specific embodiment, further set forth the present invention.Should be understood that these embodiment only to be used to the present invention is described and be not used in and limit the scope of the invention.Should be understood that in addition those skilled in the art can make various changes or modifications the present invention after the content of having read the present invention's instruction, these equivalent form of values fall within the application's appended claims institute restricted portion equally.
As shown in Figure 1, a kind of liquid sterile composite package multicolor material, be made up of 8 layer materials, described 8 layer materials are composited by low density polyethylene layer 1, high tenacity whole wood pulp cardboard paper layer 2, low density polyethylene layer 3, ethylene-methacrylic acid copolymer EMAA layer 4, aluminium foil Al layer 5, ethylene-methacrylic acid copolymer EMAA layer 6, low density polyethylene layer 7,8 hot pressing of metallocene catalysis linear polyethylene M-LLDPE layer from outside to inside successively.
Described metallocene catalysis linear polyethylene M-LLDPE layer 8 component comprise the metallocene of 30%-60%, the polyethylene of 40%-70%.
A kind of method for preparing liquid sterile composite package multicolor material, comprise successively the punching of step cardboard printing, impression, with compound, the extrusion coated hot sealing layer of aluminium foil heat seeling coating, extrusion coated sealer, the layer of 8 layer materials with the compound order of layer is: (1) low density polyethylene layer and ethylene-methacrylic acid copolymer EMAA layer are compound; (2) composite bed of step (1) and metallocene catalysis linear polyethylene M-LLDPE layer 8 are compound; (3) compound other material; (4) last compound low density polyethylene layer 1.
Compound tense employing coextruded structure is extruded two-layer simultaneously or trilaminate material carries out compound.
