Description
Technical field
The present invention relates to packaging bag print fields, and in particular to a kind of food pack plate making technique.
Background technique
Food pack is one kind of package design, for the ease of fresh-keeping, storage food in life, to produce
Product packaging bag.Food pack, which refers to, directly to be contacted with food, for containing and protecting the membrane container of food.
The production procedure of food pack is: after plan, design, plate making, compound, curing, cutting, bag making, product examine
Obtain finished product.Wherein, plate making, which refers to, is made printing plate for figure or original copy for type composition, and colorant printing ink is coated in version, passes through
Colorant printing ink is transferred on paper or other stocks by pressurization, and a kind of technique of massive duplication rapidly.
At present the printed patterns on many food packs due to adhesion and stability it is not strong, just by slight friction
Easy stamp falls, and causes pattern imperfect, is unfavorable for selling.In addition to this, the color bleeding degree of pattern is bad, is chronically exposed to sky
Also it is susceptible to the influence of various substances in air in gas and takes off color gradually, this can also be unfavorable for selling, therefore, right
Pattern on food pack is studied, and the stability of the integrality and color that guarantee pattern form is of the invention mainly to grind
Study carefully direction.
Summary of the invention
The present invention for the above technical problems, provides a kind of food pack plate making technique, to process
Wearability is strong, the good food packaging pattern of color stability.
In order to solve the above technical problem, the present invention provides following technical solutions: a kind of food pack printing engravers
Skill, comprising the following steps:
Step 1: preparing film base: using titanium alloy material, cutting film forming block or film item are carried out to it, in film block or film
The pattern of shaping on item；One layer of UV chemical treatment layer is smeared in pattern；
Step 2: painting photosensitive liquid: after UV chemical treatment layer is dry, being smeared back and forth again in the pattern of engraving photosensitive
Liquid, the dosage of photosensitive liquid are 30~40g/m2；
Step 3: dry: the film base for having smeared photosensitive liquid is put into baking oven and is dried, temperature is 40~50 DEG C, when
A length of 60~80min；
Step 4: the film base after dry is placed on UV coating moulding press, with 9~10g/min coating weight by UV laser hologram
Coating is coated on film base, fits closely UV laser hologram coating with photosensitive liquid；
Step 5: completing to superscribe rubber outside the film base after step 4, by film laminator Pressurized-heated, make the vulcanization of rubber at
Type cuts off rubber pattern to obtain printed patterns then along the profile of pattern, as last to reprint onto food pack
Printing plate.
Preferred scheme one: the dosage of UV chemical treatment layer is 20g/m in step 12。
Preferred scheme two: the dosage of photosensitive liquid is 40g/m in step 22。
Preferred scheme three: temperature is 45 DEG C in step 3, Shi Changwei 80min.
Preferred scheme four: the pressure of moulding press is 4kg, speed 28m/min in step 4.
The invention has the benefit that
1, it uses titanium alloy material as the substrate of engraving film base in the present invention, has high intensity, corrosion resistance good and high
Heat resistance, while its plasticity is good, is easy to carve out pattern, guarantees the integrity degree of pattern, lays the foundation for subsequent processing, together
When, titanium alloy is also sturdy and durable, conducive to satisfactory pattern is processed, so that pattern has the effect of permanent holding shape
Fruit.
2, select coating of the UV chemical treatment layer as first layer, UV laser hologram coating as the last layer coating,
Under process conditions, so that finally obtained packaging bag pattern is beautiful, enhances metal-like and wearability, make in packaging material for food
Pattern persistently shape is kept not change.
3, the sensitivity of pattern can be enhanced in the photosensitive material being coated with, and is conducive to pattern-forming, the color of holding pattern
Steadily in the long term.
In summary: mutually being cooperateed between each step of the present invention program, promote the pattern on manufactured food pack
Shape and color is stable for a long time is present in packaging bag, and the friction Jing Guo appropriate dynamics will not take off easily, be conducive to
It transports and during food selling, the newness of packaging is kept, conducive to the sale of food.

Comparative example 1: the difference from embodiment 1 is that:
Aluminium alloy is used in step 1；Delete step 2 and step 3.
Comparative example 2: the difference from embodiment 1 is that:
UV chemical treatment layer is not smeared in step 1 in pattern；Delete step 4.
Experiment: the food pack made of above-mentioned three groups of embodiments and two groups of comparative examples is rubbed by 5N size dynamics
Wipe pattern, observation after the 2min that rubs pattern it is complete whether, and by food pack as 2 Zhou Houguan of outdoor placement
The color density of pattern is examined, record the results are shown in Table 1.
Table 1:
| Group | The integrated degree of pattern | The color situation of pattern |
| Embodiment 1 | Pattern is intact | Color is brand-new complete |
| Embodiment 2 | Pattern is intact | Color is brand-new complete |
| Embodiment 3 | Pattern is intact | Color is brand-new complete |
| Comparative example 1 | Pattern has the abrasion of 1.5/4 area degree | Part colours shoal light |
| Comparative example 2 | Pattern has the abrasion of 1/2 area degree | All colours shoal light |
It can be seen that food pack made of the scheme of embodiment in same experimental station the record result of table 1
Under the conditions of reason, the newness of the integrity degree of pattern and color with just make without significant difference, however through and deletion
Step 2 and step 3 in the present invention use aluminium alloy as the comparative example 1 of substrate, and do not smear UV chemical treatment layer；It deletes
Except the comparative example 2 of step 4, the pattern on food pack obtained is schemed after the influence of experiment condition and environment
The integrated degree of case and the integrated degree of color are influenced to different extents, this just illustrates in the present invention program, Mei Yibu
Between be substantially play function and effect all linked with one another, the generation for beneficial effect of mutually promoting.
