With the accession to the WTO, people's awareness of their own health, environmental protection has become a replacement of pharmaceutical products and more stringent quality standards, severe ecological imbalance has constituted a great challenge for human survival. In contrast, the State Drug Administration recently stated in the "National Standard for Pharmaceutical Packaging Containers (Materials)" that it has been specified on June 1, 2004 for YBB00132002 (General Requirements for Composite Films and Bags for Pharmaceutical Packaging). Technical standards.

After conducting research on the standards pointed out in the regulations, the author believes that only in strict accordance with YBB00132002 can it be brought into line with the international market. Only by reaching YBB00132002 can we meet environmental protection requirements. In the packaging film and packaging system for pharmaceutical packaging, packaging inks, adhesives, and substrates for packaging films for pharmaceutical packaging, three-side seals, middle seals, organ bags, self-contained bags, and Zipper bags were developed. The strict and rigorous technical specifications limit not only imposes higher requirements on the formula design of inks and the source of varnishes and raw materials, but also in the production process (including workshops, equipment, facilities), ink packaging and use, etc. It is also necessary to revisit the theme of environmental protection. The environmental protection requirements are very strict, and the environmental management system must be protected from the source - the production of substrates, the evaporation of solvents from the adhesive or coating of the protective layer of the printing ink during the printing process (pollution of the environment Quantity) consumption.

In this regard, the author combines the above general rules and requirements in the following research and development of high-temperature pharmaceutical aluminum foil packaging printing inks:

1. Strictly use clean raw materials; 2. Use clean equipment and facilities; 3. Use clean packaging containers; 4. Use materials that can be recycled or recycled; 5. Use simple processes and Strict control of material loss control to reduce the emission of pollutants; 6. The generated waste should be harmless, resource-efficient and minimized; 7. The pollution caused by ink must not exceed the technical parameters specified in the YBB00132002 standard. 8. The cleaning of packaging printing inks should not decompose and produce contamination when the temperature is as high as 180-250°C.

In order to achieve environmental protection control in the design, production, printing, cutting, heat sealing and other process links, the author combines the experience of Jiangsu Zhenjiang Jiangzhou Pharmaceutical Packaging Co., Ltd., Henan Kaidi Pharmaceutical Packaging Co., Ltd. and other manufacturers to use a comprehensive analysis. The phenomenon of the failure of the packaging printing ink in the printing process, causes and treatment methods. For example: 1. The type, specification, technical parameters and production date, nature, status, and toxicity of the raw materials used; 2. The degree of pollution of water, sound, gas, and slag generated during the production process; 3. The upper limit of the production quality rate. And the lower limit requirements; 4, the contaminant components, the method of discharge and the residual amount of solvent residues; 5. The safety performance of the product.

All these are all closely linked to the quality of ink products, printing effects, after-sales technical services, environmental awareness and preventive measures must meet the standards stipulated by YBB00132002 in order to achieve comparable with multinational companies packaging printing ink products, and even meet or exceed international The current ink manufacturing level in the market. This is not only an opportunity for China's packaging and printing ink industry and packaging and printing companies to form new partnerships, but also the most difficult and inescapable challenge in this global market economic integration.
High-temperature transparent ink formulation design and manufacturing process examples.

First, formula design (as shown in Table 1)

Second, high-temperature transparent printing ink formula design (mainly printed pharmaceutical packaging products) (as shown in Table 2)

The scope of application of this formula

1. Single linking material is OP glue (liquid) / coating protection coating;

2. When the 2042# resin is changed to 582, it is transparent and light in color;

3. When the binder is increased 2042 # resin or 582 resin to improve the attachment fastness;

4. After the LM-405 resin is added to the link material, the gloss can be improved. Secondly, adding the leveling brightener to the linking material is also one of the methods to increase the gloss.

5. When the increase of 1010, can greatly reduce the content of easy oxide (easy oxide is the country's main technical standards) / increase the stability of high temperature resistant ink and varnish;

6. When the MR-30 resin is increased, the heat resistance of the ink and the varnish can be greatly improved, but excessive addition will often affect the curing speed.

7. When the ethyl acetate single dilution solvent is changed to (47.14% acetone, 35.35g/0 ethyl acetate, 17.5% alcohol), the solvent residue in the film of the ink and varnish can be greatly reduced; Greatly improve the speed of printing and coating; Third, it can greatly improve the adhesion of ink and varnish; Fourth, it can greatly improve the gloss of ink film and varnish film; Fifth, it can reduce the use cost of thinner material (solvent) by 10%. About to improve the printing company's production profits.

Note: The main requirements: A, in a certain high temperature conditions, tape sticking does not fall off; B, under certain conditions (temperature) under the heat seal pressure after the ink film, varnish film is not sticking out; C, in a certain Under high temperature conditions, no discoloration, no fading, no loss of color/varnish light (rainbow phenomenon); D, under certain high temperature conditions, easy oxide (both consumption) can not be greater than 1.5ml.

Outlook:

When we leapfrogged from the previous generation of pharmaceutical aluminum foil packaging and printing inks to this generation of environment-friendly pharmaceutical high temperature resistant packaging printing ink technology, only calmly faced it, strictly followed the YBB00132002 standard for pharmaceutical packaging printing inks and pharmaceutical aluminum foil coatings. Oil research and exploration continue to develop, innovate, and improve around environmental protection so that we can contribute our due responsibilities to human survival.
