CN103088716A - Production technology of logical positioning laser transfer paper - Google Patents

Abstract

The invention discloses a production technology of logical positioning laser transfer paper. At present, a secondary printing protective layer is adopted for logical positioning transfer, aluminum washing and gold stamping treatment are carried out, and the work time is complicated and simple; moreover, because of the technical technology, logical transfer aluminized patterns and words usually have the quality defects that the edges of the patterns and words are rough or disconnected. The production technology comprises the following steps of film coating, seamless molding, vacuum aluminum plating, gravure electric roller making, positioning and gluing compounding of logical patterns or words, and peeling. The film is directly glued and compounded logically through the electric roller, so that the production technology is short in work time, low in cost, environment-friendly and safe; and the edges of the patterns and words after being transferred are prevented from being rough, so that the product quality is refined.

Description

ー kinds of local positioning laser transfer paper production Ester Arts

FIELD

[0001] The present invention relates to printing packaging technology applied to cigarette pack, gift paper and high-grade alcohol, specifically ー wrong kind of localizing production of the transfer paper exit Ester arts.

Background technique

[0002] Vacuum Metallized paper in the late 1970s began to be used on the label and decorative gift wrap. In the late 1990s, only a good image for its environmentally friendly products and sophisticated processing equipment and Ester arts popular in European and American markets, followed by the landing of China's market. Because of its noble metal texture in appearance, relatively low cost price compared with similar products, reliable printing performance, good moisture, moisturizing properties, and biodegradable, recyclable environmental performance, more and more printing and packaging favorite industry, increasingly wide range of applications. The partial transfer sheet and the surface layer is formed into a partial transfer of sprayed aluminum metallized paper, which has obvious advantages in more specific terms, it can serve as seed ー printing paper, white paper (sheet) surface of a printed pattern of silver, then feed ー printing step, the printing sheet is formed; it can also use a strong visual effect between the spray pattern and the aluminum directly as paperboard packaging with security features, in addition, it may be substituted after printing in some respects Ester stamping process in the arts and so on. Therefore, local positioning laser transfer paper products have been deeply favored by the packaging industry, and with the corresponding proposed a more refined quality requirements. Today at home and abroad for finishing packaging products, are based on cold-hot printing technology, printing is completed, the offline perm transfer. Artistic offline Ester the following problems: First, many production lines, production efficiency is low; the Ni, the Eito program product, quality is difficult to control, high consumption, high rejection rate; Third, product accuracy is poor. Since Ester reasons of process technology, local metastasis aluminum recurrent character pattern defect pattern quality text rough edges or disconnection occurs. Therefore, development of a method of producing mass Ester Arts more refined localizing laser transfer paper is imperative.

SUMMARY

[0003] The present invention solves the technical problem is to overcome the above-described deficiencies present in the prior art, to provide localized species ー positioned Ester laser transfer paper production arts, so that the quality of products produced more refined.

[0004] To this end, the present invention employs the following technical solution: Ester ー seed production arts localizing the laser transfer paper, characterized by comprising the steps of:

1), the coating film: The release coating layer is transferred on the film, after completion of the coating, once dried through an oven by applying a printing machine;

2), seamless embossing: The dried film obtained by transfer molding machine seamless embossing pattern on the CD;

3), vacuum aluminum: a thin film on the embossing pattern is laser or metalised aluminum plating medium vacuum dryer;

4), custom gravure electric carving roll: The required product pattern or character, the corresponding patterns or characters carved on the printing roller, made of engraved roll local patterns or characters (engraved roll is about a pattern or text portions carved into the cable other parts of calender rolls);

5), positioning the composite plastic: the aluminum or aluminum plating medium laser transfer film obtained by electric carving roll coating, while forming a composite paper and paper composite, and winding the drying oven;

6) Separation: The composite sheet for the aging treatment, after using the stripping machine peeling, the above transfer paper patterns or characters on the respective silver layer of aluminum. [0005] The present invention, by an electrical local positioning engraving roller coating, control local positioning the composite laser transfer film and aluminum sheet, blanching is with respect to its greatest advantage is low investment without making costly stamping Edition, structure simple, easy to operate, high cost performance. The coating requirements transferable peeling good coating loose, trimming good. Aging treatment means disposed a predetermined time (typically 24 hours).

[0006] Advantageously, the step I) of BOPP film is a PET film or a film.

[0007] Advantageously, according to step I), the coated printing speed of 90-100 m / min, temperature of the oven five sections were 80 ° C, 100 ° C, 135 ° C, 120 ° C, and 90 . . .

[0008] Advantageously,) in the step 2, seamless embossing plate during molding roll temperature 165 ° C -170 ° C, the speed of 30-35m / min, roll nip grades of 2_3kg, so that the pattern or text pressure and light pressure through non-stick coating Edition.

[0009] Advantageously, said step 3), the degree of vacuum of aluminum ~6.54X10-2 5.33X10-2 Pa Pa, a resistance, high frequency heating or electron beam, so that an aluminum wire was heated to 1400 ° gasification C~1500 ° C, so that the aluminum wire gasified rapidly evaporated, diffused and deposited on the surface of the film, the aluminum film through the process.

[0010] Advantageously, said step 4), the cable rollers 250-300 preparation cable lines, deep lines 5_7um.

[0011] Advantageously, 5) in the step to prevent the spread of glue, after transferring a pattern character appears rough edges, the glue used in the composite mass fraction of 0.5% to 1% aqueous ammonia, decreasing the viscosity of the glue coating cloth amount 3-4g / m2.

[0012] Advantageously, 5) in said step, the composite speed of 100~120 m / min, drying temperature in the region of the multifunction peripheral control 70~130 ° C.

[0013] Advantageously, the composite machine has five drying tunnel, the temperature of the same are not provided, adjacent temperature zones ni temperature difference is within 25 ° C.

[0014] Advantageously,) in step 6, 12~24 hours aging time, aging temperature environment 250C ± 5 ° C, humidity of 55% ± 10%, the peeling rate was 200 ~300m / min.

[0015] The present invention has beneficial effects: by electric carving roller partially a thin film directly on the plastic composite, Ester is shorter, low cost, environmentally safe; added ammonia glue compound employed, the lower the viscosity, to prevent the glue spread, to avoid after the transfer of the pattern of text appears rough edges, so that product quality more refined.
