Abstract
The invention discloses a production process of packaging films free from undesirable odor. The key points of the technical scheme provided by the invention comprise the followings: (1), carrying out plate making before printing, and accurately controlling ink cell depth, (2) carrying out the step of printing: the step of printing mainly relates to the matching of printing liquids, the using proportion (weight ratio) of liquid raw materials of polyurethane ester dissolving printing ink to ethyl ester to stearic acid to glycerinum is 1 to 1.1-1.5 to 0.0013-0.007 to 0.0007 to 0.003. (3), carrying out the step of composition: the proportion of used liquid raw materials (weight ratio) of a polyurethane bicomponent adhesive to ethyl ester to stearic acid to glycerinum is 1 to 1.1-1.5 to 0.0013 to 0.007 to 0.0007-0.003, or of a water-soluble adhesive to stearic acid to glycerinum is 1 to 0.0007-0.003 to 0.0003-0.002; (4), cutting formed packaging films; (5), packaging and forming. According to the production process provided by the invention, through the control on two aspects, residuals after the production of composite films are qualified, products are free from undesirable odor, not only can the production efficiency be improved, but also product quality is effectively improved.
Description
Technical field:
The present invention relates to the production technology of packaging film, particularly a kind of production technology relating to the free from extraneous odour packaging film of food packaging applications.
Background technology:
In recent years, along with people are to the more and more concern of food security, food service industry improves a series of examination criteria thus, and food relevant industries are corresponding lifting standard also, and food packing industry corresponding requirements increases test item.China GB GB/T 10004-2008 " packaging composite plastic film, bag dry laminating, extrude compound " regulation, dissolvent residual total amount must not more than 5mg/m
2, benzene kind solvent must not detect and (detect and be limited to 0.01mg/m
2).In the product exceeded standard, the residual solvent detected mostly is the volatile solvents such as ethyl acetate, acetone, ethanol.The material that food flexible packing industry uses is the retarder thinner of fluent material owing to much needing use certain especially, after having produced, there is the residual of trace to volatilize completely, these diluents have certain smell, for ensureing that product " is not disliked and avoided " by consumer thus affects oneself sales volume, prestige in client uses, will require that packaging industry eliminates this smell.And as food packaging industry, but the unavoidable material using these easy generation peculiar smell is kept away in process of production, when process control a bit micro-deviation time or when sometimes affecting uncontrollable by extraneous factor, dissolvent residual will be produced exceed standard, and then generation peculiar smell, be direct infringement to product quality, economy, honor loss are caused especially to enterprise.It is evident that, control dissolvent residual, just can control Peculiar Smell to a great extent, and control dissolvent residual in industry inherence is generally all set about from self production process such as speed of production, temperature etc., or improve by improving that environment of production, these methods have certain effect, but do not have basic effect, and also there is reduction production efficiency or other quality problems such as deformation of products due to use high-temperature owing to changing production technology, environmental protect input cost is high, and effect also and not obvious.
Summary of the invention:
The object of the invention is the production technology of the free from extraneous odour packaging film designing a kind of composite membrane free from extraneous odour be processed into.
Technical scheme of the present invention is, a kind of production technology of free from extraneous odour packaging film, it is characterized in that: (1) carries out printing front plate-making, the degree of depth of accurate control ink cell, the general control ink cell degree of depth is at 38 μm-40 μm, (2) print steps, mainly printed liquid proportioning, the usage ratio (weight ratio) of liquid material of the present invention be " the molten ink of polyurethane ester: ethyl ester: stearic acid: glycerine=1:1.1-1.5:0.0013-0.007:0.0007-0.003; oven temperature when controlling printing is at 50-55 DEG C, and air draft blast velocity control is at > 20m/s; (3) ratio of liquid material that composite steps uses is: usage ratio (weight ratio) is " polyurethane two-component adhesive: ethyl ester: stearic acid: glycerine=1:(1.1-1.5): (0.0013-0.007): (0.0007-0.003) " or " water-soluble binder: stearic acid: glycerine=1:(0.0007-0.003): (0.0003-0.002) "; Control the temperature of compound tense at 50-85 DEG C, air draft blast velocity control is at > 20m/s; (4) packaging film be shaped is cut; (5) pack shaping.The molten ink of polyurethane ester described above is the molten ink of polyurethane ester that Chinese redbud ink Hebei Co., Ltd produces GNB, GSK model; Polyurethane two-component adhesive uses Beijing Comens New Materials Co., Ltd. to produce YH2975 model polyurethane two-component adhesive; Water-soluble binder uses Kunshan Guan Bao Chemical Co., Ltd. to produce the water-soluble binder of RL-640 model.
The present invention is by the control of above two aspects, and composite membrane is not only residual qualified after manufacture, and product does not have peculiar smell, not only increases production efficiency, and effectively improves product quality.
