Abstract
The utility model discloses a multifunctional polyethylene and polypropylene co-extruded composite membrane with good adhesion among layers, which is formed by compounding three material layers. The outermost layer and the innermost layer of the membrane are respectively a polyethylene layer, and a polypropylene core layer is arranged between the two polyethylene layers. The utility model combines the advantages of the polyethylene membrane and the polypropylene membrane, and has the advantages of good low-temperature heat sealing performance, good stiffness, high elastic modulus and the like. Moreover, with the low cost, good feeling, high transparency and good smoothness, the utility model can be widely used in the tissue paper packaging, the food packaging and the packaging of other products, particularly in the high-speed mechanically automatic packaging of products.
Description
Technical field
The utility model relates to a kind of packing film goods, especially relates to a kind of polyethylene and polypropylene multifunctional coextrusion-lamination film with good interlayer adhesion.
Background technology
Polyolefin film is to use on the market that packing film, especially polyethylene film and its range of application of polypropylene film are especially extensive very widely.In general, polypropylene has high transparent, good thickness evenness, deflection height, but its low-temperature heat-sealing performance is relatively poor relatively.Though polyethylene film low-temperature heat-sealing performance is better relatively, its deflection is little, when high-speed packaging, causes the card machine easily and influences production capacity.If increase its deflection by the method that improves polyethylene film thickness merely, certain limitation is not only arranged, also can improve the price of packing accordingly.If with other deflections preferably film to carry out dry type compound, not only increased price, produce the dissolvent residual phenomenon in addition, properties of product and use are caused adverse effect, nor environmental protection.
Increasing polyethylene film deflection method commonly used is to add to increase firm agent (having another name called intensity strengthening agent).The firm agent of using that increases at present mainly contains organic and inorganic two types, it is organic that to increase firm agent mainly be monobasic or binary aliphatic acid and aralkyl acid and its esters, they improve the product processing characteristics for the modulus that increases polymer certain effect, but can influence the machinery and the chemical property of product, and relatively poor with polyolefinic intersolubility, polyolefinic transparency there is certain negative effect.It is another kind of that to increase firm agent be that inorganic matter increases firm agent, as inorganic nano-fillers such as superfine talcum powder, kaolin, mica, silica gel carbon black etc., though theoretically, Nano filling can play nucleator, improve material stiffness, improve mechanical property, yet the characteristic that there are the non-homogeneous effect in Nano filling and polymer body and are difficult to dissolve each other, be difficult to reach during therefore actual the use and increase very effect preferably, and the transparency of infringement goods, it is of less types and cost an arm and a leg to add Nano filling, so the scope of application is wideless.
Summary of the invention
The utility model mainly is to solve to have now to be applied to the existing deflection of film of packaging field and the technical problem that heat sealability can not be taken into account, in the hope of preparing a kind of multi-functional polyolefin coextrusion-lamination film with good low temperature heat sealability and higher stiffness and transparency.
The utility model is mainly solved the problems of the technologies described above by following technical proposals:
This film is composited by trilaminate material, is positioned at the polyethylene layer that is of film outermost layer and innermost layer, and between the two layers of polyethylene layer is the polypropylene sandwich layer.
As preferably, described polyethylene layer and polypropylene sandwich layer intersection also have a permeable formation.
As preferably, the outermost surface of described film has a lot of pits.
Owing in polyethylene layer, added the elastomer that propylene-ethylene copolymers or polyethylene octene elastomer or styrenic thermoplastic elastomer etc. have compatible role.And these special elastomers all have the good binding effect to polyethylene and polypropylene, therefore vinyon layer and polypropylene plastics sandwich layer prolong poly-compound tense, therefore polyethylene layer and polypropylene sandwich layer interpenetrate, naturally form a permeable formation, can well increase adhesive force between polyethylene film and the polypropylene screen like this, it is stable to make that three-layer composite structure of the present utility model remains in heat seal process.
The utility model combines the advantage of polyethylene and polypropylene film, it is good to have the low-temperature heat-sealing performance, characteristics such as deflection height, elastic modelling quantity height, and use cost is low, good hand touch, the transparency height, smooth performance performance is good, the packing that can be widely used in paper handkerchief packing, packaging for foodstuff and other products, the high speed machines that is particularly useful for product is packed automatically.
Description of drawings
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of preferred implementation of the present utility model;
Fig. 2 is a B shown in Figure 1 place partial enlarged drawing.
The specific embodiment
Fig. 1 is the structural representation of a kind of preferred implementation of the present utility model.It is composited by trilaminate material, and what be positioned at film outermost layer and innermost layer is polyethylene layer 1,3, and between the two layers of polyethylene layer is polypropylene sandwich layer 2.And by Fig. 2 further as can be known, also have a permeable formation 11 at polyethylene layer and polypropylene sandwich layer intersection.For the ease of printing on film or carrying out compoundly with other base material, the outermost surface of film is handled through high-frequency discharge (corona), has therefore formed a lot of pits 12.
Its production process is: by weight percentage with polyvinyl resin 75%, propylene-ethylene copolymers 24.8%, silica 0.1% drops into respectively after erucyl amide 0.1% mixes in first the extruder hopper and second extruder hopper of cast film production line; With polypropylene copolymer 99.2%, phosphoesterase 30 .3%, silica 0.3%, sorbitan ester 0.2% mix in the 3rd extruder hopper of back input by weight percentage; From the fused mass process loading head that three extruders come out, T pattern head is extruded, and passes through cooling and shaping then, and extexine carries out sided corona treatment, deburring, and rolling promptly obtains the utility model film article.
In order to verify effect of the present utility model, polyolefin coextrusion-lamination film and existing P P, PE composite membrane that the above-mentioned specific embodiment is prepared compare test, and its result is as follows:
Table 1 packaging film contrast test data:
Result of the test shows: compare with conventional P E, PP composite package film, the utility model film mainly contains following characteristics: 1. good impact resistance, deflection height, elastic modelling quantity height, all greater than the PP composite membrane of high-stiffness, elongation at break then approaches the high PE composite membrane of elastic modelling quantity to its hot strength; 2. initial heat-sealing temperature is low, and the initial heat-sealing temperature of the PE composite membrane better than low-temperature heat-sealing performance is also low; 3. glossiness is fine, and mist degree is excellent, so the properties of transparency of product is better; 4. coefficient of friction is little, so the feel of product is better.5. the interlayer adhesion is strong, and three-decker is difficult to separate.
