At present, the government strengthens the supervision and management of food labels, regulates the labeling of food labels, prevents quality fraud, protects the legitimate rights and interests of enterprises and consumers, and formulates management methods for labeling machinery in packaging machines. The main contents are as follows: 1. The food labeling should clearly indicate the production date and shelf life of the food. 2, food identification should be marked with a list of food ingredients. 3. The food labeling in packaging machinery shall indicate the national standard, industry standard, local standard number or enterprise standard number that has been filed by the company. 4. If the standards for food execution clearly require the labeling of food quality grades and processing techniques, they shall be marked accordingly. The establishment of food labeling machines has brought opportunities to the packaging machinery industry. The above food labelling management regulations have promoted the development of the packaging machinery inkjet printer series in the food industry and broadened the market share of the packaging machinery industry.
natural rubber, synthetic rubber, reclaimed rubber, carbon black, various additives, fillers, matrix materials etc.The term rubber is derived from the Indian cau-uchu, meaning "tree of tears," a highly resilient polymeric material with reversibly deformable properties that is flexible at room temperature and produces large deformations with little external force, Remove the external force can restore the status quo. Rubber is a completely amorphous polymer with a low glass transition temperature (T g) and a high molecular weight, often greater than a few hundred thousand.
The early rubber was latex from plant such as rubber tree, rubber grass and the like, which was made of processed materials with elasticity, insulation, imperviousness and air. High elasticity of the polymer compounds. Divided into two kinds of natural rubber and synthetic rubber. Natural rubber is made from rubber tree, rubber grass and other plants made of plastic processed; synthetic rubber by a variety of monomers derived by polymerization. Rubber products are widely used in all aspects of industry or life.
Isoprene rubber, like natural rubber, has good elasticity and abrasion resistance, excellent heat resistance and good chemical stability. Isoprene rubber raw (raw) strength was significantly lower than natural rubber, but the quality of uniformity, processing performance superior to natural rubber. Isoprene rubber can be used in place of natural rubber to make truck tires and off-road tires. It can also be used to produce various kinds of rubber products.
