Description
Technical field
The present invention relates to the production technology of intaglio printing packaging film, especially a kind of production work suitable for environment-protective packaging film
Skill.
Background technique
In recent years, thus the increasingly concern food-safe with people, food service industry improve a series of detection
Standard, food relevant industries also accordingly promote standard, and food packing industry corresponding requirements increase detection project.China national standard GB/
T10004-2008 " it is compound to be packed for composite plastic film, bag dry laminating, extrusion " regulation, dissolvent residual total amount must not exceed
5mg/ ㎡, benzene kind solvent must not detect (detection is limited to 0.01mg/ ㎡).Food contact material resin should meet GB
4806.6-2016, the material that food flexible packing industry uses especially fluent material is due to much needing to use certain dilution molten
Agent has micro residual not volatilize completely after the completion of production, these diluents have certain smell, are in client's use
Guarantee that product is not influenced oneself sales volume, prestige by consumer " disliking and avoiding ", just may require that packaging industry eliminates this smell.
And as food packaging industry, the unavoidable material that peculiar smell is easy to produce using these in process of production,
When being influenced uncontrollable when process control micro- deviation a bit or sometimes by extraneous factor, it is exceeded to generate dissolvent residual,
And then peculiar smell is generated, it is directly to damage to family quality, is even more to cause economic loss to enterprise.It is readily apparent that control
Make dissolvent residual, so that it may Peculiar Smell is largely controlled, and in control dissolvent residual generally all from certainly in industry
Production process of body such as speed of production, temperature etc. is set about, or is improved by improving that environment of production, these methods have centainly
Effect, but do not have basic effect, and there is also reduce production efficiency or due to using high temperature due to changing production technology
Degree and other quality problems such as deformation of products, improve that environmental input is at high cost, and effect is also not obvious.
Summary of the invention
The object of the present invention is to provide a kind of low-residual, free from extraneous odour and the relatively simple novel environment friendly packaging films of processing technology
Production technology.
The technical scheme is that a kind of production technology of novel environment friendly packaging film, it is characterised in that: (1) first match
Water-based ink；40% waterborne polyurethane resin, the organic pigment of 20-30%, 5-10% dehydrated alcohol, 1-2% aqueous promoter are selected,
20-30% ionized water；
(2) carry out gravure plating before printing, control the depth of ink cell, control ink cell depth in 85 lines/inch-100 line/inch,
23-28um is deep；
(3) print steps, the proportion of printed liquid are as follows: the use ratio (weight ratio) of liquid material is aqueous, environmental protective ink: nothing
Water-ethanol: tap water=1:0.5-0.9:0.6-0.8, control printing oven temperature is at 70-80 DEG C, and two sections of oven temperatures are in 75-85
DEG C, into air draft blast velocity control in 20m/s or more, control into exhaust air rate in >=6000m3/h；
(4) composite steps: the film after printing is placed on the first let off roll, and the film on the first let off roll is coated with aqueous binder
It is bonded, then dries moisture through drying tunnel, bonded with the second let off roll (the generally materials such as VMCPP film, PE film)；Drying tunnel
The temperature control of drying in 65 DEG C of an area, 85 DEG C of 2nd area, 90 DEG C of 3rd area, into air draft blast velocity control in >=20m/S；Or
Film coating on one let off roll is bonded using adhesive for solvent-free use.
The weight ratio proportion of adhesive for solvent-free use described further is Isocyanate prepolymers body: hydroxyl polyurethane chemical combination
Object=100:75-80.
Aqueous promoter described further is BYK auxiliary agent.
The beneficial effects of the invention are as follows friendly environment, low-residual, free from extraneous odour；It is applied widely；Using water-based ink work
After skill, dissolvent residual detected value is below 0.5mg/ ㎡, and comparison solvent-based ink technique is very big after two sections of baking ovens are heated at high temperature
Degree reduces dissolvent residual ratio, and smell significantly reduces.It is printed using water-based ink, is printed compared with traditional solvent-based ink
Brush, VOC emission are greatly reduced, and alleviate environmental improvement pressure.
