Abstract
The present invention relates to a making method of a soft package material with barrier properties for liquid food, which comprises the following steps: 1, primarily unreeling on a coated backing material; 2, extruding to compound; 3, extruding a compounded layer in the second step and polyethylene in a molten state by a No. 2 extruding machine to compound, and then, compounding a polyethylene layer on. The soft package material with barrier properties for liquid food made by the method comprises a backing material layer, a paper layer and two polyethylene layers. The distribution order of the layers respectively is the polyethylene layer, the paper layer, the polyethylene layer, a coating layer and the backing material layer or the polyethylene layer, the paper layer, the polyethylene layer, the backing material layer and the coating layer. When the method of the present invention is used for making materials, four layers are directly made from two layers, and then, five layers are made. Thus, the making steps are reduced, the production cost is reduced and the production efficiency is increased.
Description
Technical field
The present invention relates to a kind of preparation method and material of barrier liquid food flexible packing material.
Background technology
Know packing and transportation food liquid in the close packing container of the liquid that laminate wrapping material is manufactured in the prior art already; this packaging laminate comprises a plurality of independently layers; they lump together given finished product packing container with packaging product required mechanical property and chemical-resistance; common packaging laminate has refill layer or back flow liner firm in structure but that can fold; these sandwich layer both sides protecting this wet quick property sandwich layer, and make wrapper can carry out heat seal with the outer coating of plastics preferably polyethylene simultaneously.The above-mentioned feasible close packing container of liquid that can produce dimensionally stable of this class packaging laminate that paper or ply of board and plastic layer are only arranged, but the sealing for oxygen and other gases is poor, therefore must add that one or more layers has bubble-tight material (being called barrier layer), so that this packaging laminate can be used as the packing container to oxygen sensitive product etc.Swedish patent 440519 discloses a kind of material, in the above the top layer of polyethylene alcohol layer that added of said packaging laminate.But also there is defective in this material, and Chinese patent ZL96198882.7 discloses a kind of laminate wrapping material that comprises polyvinyl alcohol layer and preparation method thereof for this reason, and its preparation method adopts the method for extruding and coating, has added one deck plastic layer outside polyvinyl alcohol layer.But still there is very big defective on the manufacture craft, its procedure of processing be from two layers to three layers again to four layers again to five layers, the procedure complexity is loaded down with trivial details, be difficult for grasping, and product cost height, the material of product also exists barrier low in addition, and heat sealability is bad, its low-friction coefficient and the bad shortcoming of low static behaviour.
Summary of the invention
At the shortcoming that above-mentioned prior art exists, the long-pending experience of being engaged in this area work for many years of the inventor, feasibility study repeatedly gets generation of the present invention eventually; The invention provides a kind of preparation method and material of barrier liquid food flexible packing material.
The technical solution used in the present invention is: a kind of preparation method of barrier liquid food flexible packing material, its making step is: 1, will just unreel on the coated base material, with polyester film, polyethylene film or polypropylene screen, the coating materials are polyvinylidene chloride or nylon resin with base material in coating.2, extrude compound: the polyethylene under above-mentioned base material and paper and the molten condition is extruded the composite bed that is combined into substrate layer, ply of paper and polyethylene layer at an extruder, and the temperature when extruding is 280 ℃-350 ℃, and polyethylene is a molten condition under this temperature; Polyethylene is low density polyethylene (LDPE), metallocene PE or linear polyethylene.3, with compound good composite bed of the 2nd step again with molten condition under polyethylene extrude by No. two extruders compound, compound again last layer polyethylene layer, this polyethylene layer and ply of paper are combined with each other becomes final products.
A kind of barrier liquid food flexible packing material, this material comprises substrate layer, ply of paper and bilaminar polyethylene layer, and substrate layer is polyester film, polyethylene film or the polypropylene rete that is coated with coating layer, and coating layer is polyvinylidene chloride or polyamide resin layer; Ply of paper is refill layer or back flow liner, polyethylene layer is a low density polyethylene (LDPE), metallocene PE or linear polyethylene layer are compounded with one polyethylene layer wherein between described base material that is coated with coating layer and the described ply of paper, another layers of polyethylene layer is compounded in the another side of described ply of paper.
Above-mentioned each layer distribution sequence is polyethylene layer, ply of paper, polyethylene layer, coating layer, substrate layer or polyethylene layer, ply of paper, polyethylene layer, substrate layer, coating layer successively.
The thickness of above-mentioned each layer is: polyethylene layer 15 μ of ply of paper 70 μ, outer field polyethylene layer 30 μ, internal layer, coating layer 3 μ, substrate layer 15-18 μ.
Directly do from two layers during the affected material of the inventive method and make four layers, and then, reduced making step, reduced production cost, improved production efficiency to five layers.
The characteristics that material of the present invention has:
1, gives the product high barrier, comprise low oxygen transmission rate and rate of perviousness;
2, low-friction coefficient, low static behaviour have guaranteed that the use on automatic packaging machine is quick;
3, fragrance protectiveness, the guarantor performance of distinguishing the flavor of prolongs the shelf life of product.
4, heat sealability (low temperature) is good, has improved the efficient in can production.
5, good wearability is protected product in carrying, placement, storage and transport process.
6, material non-toxic of the present invention, free from extraneous odour meet food hygienic standard fully, and coated film meets the FDA standard.
The present invention is described in further detail below in conjunction with drawings and the specific embodiments:
Description of drawings
Fig. 1 is a material making step schematic diagram of the present invention;
Fig. 2 is the utility model material cross-section schematic diagram.
