It is understood that with the continuous improvement of the supply capacity of China's plastic flexible packaging industry, more opportunities will be provided for the export growth of products. Recently, the National Technical Committee for printing standardization held a meeting in Beijing to discuss the establishment of the drafting group of the national standard for gravure printing process control and quality inspection methods for plastic flexible packaging and related issues for standard formulation.
The meeting confirmed that Beijing Printing Institute, Shanghai Zijiang color printing and packaging Co., Ltd., gravure printing branch of China Printing Technology Association, Zhejiang Chengxin packaging material Co., Ltd., Hangzhou dingzheng printing and packaging Co., Ltd., Shaanxi Beiren Printing Machinery Co., Ltd. were the drafting units of the national standard.
The topic, framework and content of the national standard were discussed at the meeting. The framework is: 1 scope; 2 normative references; 3 terms and definitions; 4 quality control requirements (4.1 raw materials, 4.2 equipment, 4.3 tooling, 4.4 process, 4.5 operation specification); 5 inspection methods.
In the national standard, the printability indexes of substrate materials include wetting tension and uniformity, thermal shrinkage, tensile strength, friction coefficient, thickness deviation, transparency, width deviation, tensile strength and appearance. Printing materials include: BOPP, PE, pet, CPP, BOPA, PVC, OPS, etc.
Process indicators mainly include: printing environment temperature and humidity (supplemented by other conditions), tension, oven temperature, exhaust air volume, knife line, spot color ink error range, imprint cylinder pressure. The meeting determined that the first draft of the national standard drafting group should be completed by the end of June, and the first working meeting of the drafting group would be held in July with the venue to be determined.
China's flexible packaging industry attaches more and more importance to energy saving, consumption reduction, emission reduction and safety on the basis of the original emphasis on style and persistence. This is because we should retain the spirit of modified plastics and enhance the skills to deal with the problem that BOPP plastic film is easy to infect.
In recent years, continuous progress has been made in the recycling and reuse of plastic waste, and the secondary pollution problem has been gradually solved. It is expected that the future development prospects will be broader. In order to make great progress in plastic flexible packaging, it is necessary to advance the production technology and reduce the use of raw materials.
