Description
Technical field
The present invention relates to a kind of packaging film, particularly a kind of film papery Easy tearing lid and preparation method thereof.
Background technology
Bottle cap is a food ring important with the drink packing, is also the place that the consumer contacts with product at first.Bottle cap has the content of maintenance product airtight performance, also has the function of antitheft unlatching and security aspect, therefore is applied in widely on bottled product, so bottle cap is food, drink industry, wine, chemical industry, the upstream industry of pharmacy industry, be the key product of bottle container packing.Along with the progress of science and technology, the packaged form of plastic containers seal cap appears on the market of China's packaging for foodstuff in recent years successively, easily tear layer as cold drink or box-packed instant noodles top.Chinese invention patent application as application number 201210411811.1, applying date 2012-10-24 discloses a kind of sealing epiphragma, and described epiphragma is pet layer, aluminium lamination, ethylene acrylic acid co polymer layer, bimodal polyethylene layer, composite polyethylene layer from outside to inside.There are two defects in the layer material that easily tears in the market: 1, sealing is insecure, and leakage, gas leak phenomenon are many, cause quality problems and loss.2, be difficult for tearing after the sealing.
Summary of the invention
The invention provides a kind of film papery Easy tearing lid that seals firmly, easily removes.
The present invention also provides a kind of preparation method of described film papery Easy tearing lid.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of film papery Easy tearing lid, comprise successively: easily tear layer, aluminium foil layer, low density polyethylene layer and copperplate ply of paper, the described layer that easily tears is mixed by following component: low density polyethylene (LDPE): 78-82%, high-molecular polythene 4210:14-16%, anti-bonding agent KMB 15F-4:4-6%.Forming the composition that easily tears layer is that film is easily torn material.Existing sealing epiphragma product does not have easily tearing layer or only with plastic products, replacing described in the present invention, be unfavorable for like this it to be torn after environmental protection or sealing, the consumer uses inconvenience, and when using plastics as seal closure, different materials needs corresponding the use simultaneously; The common film of not adding is easily torn the seal closure of material, there will be sealing not firm when heat-sealing, gas leakage, leakage material phenomenon; Added after film easily tears material on its surface, this seal closure enlarges the material range of application of cup, can be paper, PP cup, PS material, PE material, PVC material, PET material.
As preferably, described low density polyethylene (LDPE) (LDPE) model is 1C7A, and high-molecular polythene is 4210, and anti-bonding agent is KMB 15F-4.High-molecular polythene 4210 is ternary polymerizations, the high-molecular polythene that is comprised of ethene, propylene, maleic anhydride; Anti-bonding agent is that KMB 15F-4 is a kind of high transparent spongy flexible devitrified glass, the microcosmic smoothness on energy strict guarantee film material surface.
As preferably, the described layer that easily tears is mixed by following component: low density polyethylene (LDPE) 1C7A:80%, high-molecular polythene 4210:15%, anti-bonding agent KMB 15F-4:5%.
As preferably, the surface of aluminium foil layer is through sided corona treatment, and electric current is 4-6A.
A kind of preparation method of described film papery Easy tearing lid, the method comprise the steps: a, adopt low density polyethylene (LDPE) that aluminium foil and art paper are combined with each other, and form the composite bed that is followed successively by aluminium foil layer, low density polyethylene layer and copperplate ply of paper; B, to the aluminium foil surface of composite bed, adopt metal corona equipment to carry out sided corona treatment, electric current is 4-6A; C, low density polyethylene (LDPE), high-molecular polythene 4210 and anti-bonding agent KMB15F-4 are mixed according to proportioning, obtain film and easily tear material; D, with the film for preparing in step c easily tear the material by the extrusion coated aluminium foil surface to having processed of film machine curtain coating, obtain product.Existing various sealing epiphragma product just simply carries out film or LDPE and high-molecular polythene 4210 with LDPE and mixes use, the product of producing occurs that sealing is not firm, or the paper surface of producing is clamminess, can't normally use, the product that this formula is produced not there will be top phenomenon, reaches the effect of easily tearing.
As preferably, in the d step, the coating weight that film is easily torn material is 20-22g/m
2.When grammes per square metre is following lower than 20g, after product sealing, when this product need be placed in low temperature-subzero and store, there will be the not firm phenomenon of sealing or sealing to pop, after exceeding 22g, to material, be a kind of waste.
As preferably, in the d step, the technological parameter of film is:
Barrel temperature is followed successively by 195 ℃, 260 ℃, 275 ℃, 295 ℃, 330 ℃, 330 ℃,
Take over temperature: 325 ℃,
Die head temperature is followed successively by 320 ℃, 325 ℃, 330 ℃, 340 ℃, 325 ℃, 320 ℃;
Pressure roller pressure is 5-6kg,
Chilling temperature is 20 ℃, and the speed of a motor vehicle is 70m/min, and the die head mouth is 100mm to the height of chill roll.
The invention has the beneficial effects as follows: 1, easily sealing and fastness are good.2, sealing is easily torn, the convenient use.
