Third, the use of new technologies, new materials, new processes to save costs, reduce energy consumption

At present, whether it is a two-piece can, a three-piece can or a 200-liter steel drum, the development of reduction has become a general trend. In the canning industry, everyone uses DR material to produce cans, and in the barrel industry, the raw materials for producing steel drums are also continuously thinning. The original heavy-duty steel drums have a material thickness of 1.5 mm, and now almost no one cares. Most of the steel drums have a thickness of 1.0 to 0.8 mm, and the thickness of the inner and outer coating barrels of the food is reduced from 1.2 mm to 1.0 mm for many years. The thickness of the steel drum used for juice is reduced from 1.0 mm to 0.8 mm; the thickness of the conical steel barrel with ketchup is only 0.7 mm, although the thickness of the steel drum is thinned, but the quality requirements for the steel drum are improved. Grades, users who originally used Class II steel drums to meet quality and safety requirements, now require steel drums to meet Class I quality standards. This requires steel drum manufacturing companies to adopt new technologies, new processes and new equipment to meet user needs.

The DR material is the secondary cold-rolled thin strip steel, that is, the steel which is further thinned into the ultra-thin strip steel production process by the secondary cold rolling technology, and the promotion and application of the DR material realizes the saving of the packaging material resources. The DR material with a thickness of 0.15mm has been successfully applied to the large-scale production of food cans. The DR material with a thickness of 0.14mm is used for 5# and 7# food cans, which is in line with the development direction of the world packaging field.

Technological innovation has brought new markets to canmaking companies. On the basis of the successful application of DR material in tomato cans, after continuous efforts, 0.15mm DR material has been successfully applied to the large-scale production of 5# and 6# beverage cans.

The Metal Packaging industry is a resource-consumption industry. The reduction of the production factors by the thinning of the material of the DR material can greatly reduce the consumption of resources, and the material saving rate directly reaches 25%-30%. According to statistics, from 2012 to the end of 2013, after the use of DR materials and thinning optimization of metal packaging products, the total savings of steel products exceeded 100 million tons, and the canning industry saved more than 6,000 tons. At the same time, the reduction of steel consumption was reduced. The emissions of energy, water and carbon dioxide consumed in the production of steel are in line with national environmentally friendly and sustainable development strategies.

At present, the global metal packaging industry pays great attention to and attaches to the coated iron technology, which enhances the quality and safety of metal packaging products. Because the film is directly compounded on the metal surface, no longer use various solvents, it can solve the food safety problem of bisphenol A endangering human beings, eliminate the migration of harmful substances, provide a reliable guarantee for the hygiene and safety of food and beverage; and coated iron The performance of the barrel making tank is also better than the traditional printing iron products, and has significant advantages in processing, corrosion resistance and barrier properties, greatly expanding the scope of application of metal packaging products.

Compared with traditional material processing, coated iron barrel cans reduce the drying and curing process. Using coated iron can theoretically reduce energy consumption by 70% and CO2 emissions by 71%, completely eliminating industrial water consumption. And the discharge of solid waste can fully realize green, low carbon and environmental protection.

The leaders of China Canned Food Industry Association, China Beverage Industry Association and China Dairy Industry Association said that metal packaging has proven to be one of the safest and most environmentally friendly packaging forms in the world. Because of its packaging materials, it can be recycled and reused. It has a wide range of applications, such as good sealing and improved product shelf life. It can be said that metal Packaging Can solve more problems for canned food safety.

The food packaging industry has its own particularity. In addition to quality, it has higher sensitivity to safety and quality than other industries due to its direct contact with food. From the selection of materials, processes, finished product testing, and production and management systems are directly related to the safety of food packaging. Under the premise of ensuring the safety of food packaging, the development of green, environmentally friendly, novel and distinctive food packaging will be more welcomed by the market.
