Green packaging sweeps the entire packaging market POF shrink film

POF heat shrinkable film adheres to the path of sustainable development, and actively advocates energy conservation, emission reduction, and low-carbon life are currently important strategies for alleviating severe pollution in China. Nowadays, low-carbon life has become a household word, and the concept of energy conservation and emission reduction has been Deepen the development of various industries in China, such as China’s packaging industry, green packaging has swept the entire packaging market, and environmentally friendly packaging films represented by POF heat shrinkable films have set off a wave of green packaging. Combining green environmental protection and packaging concepts, POF is hot Shrink film not only embodies the modern packaging concept, but also fully embodies its green and environmental protection characteristics, conforms to the mainstream of the development of an energy-saving society, and has development significance for the times. The main raw materials of OF shrink film. The main raw materials of three-layer co-extruded heat shrinkable packaging film include LLDPE (linear low density polyethylene), TPP (ternary copolymer polypropylene), PPC (binary copolymer polypropylene) and necessary functional aids. Agents such as slip agents, anti-blocking agents, antistatic agents, etc. These raw materials are environmentally friendly and non-toxic materials, no toxic gas or odor will be generated during processing and product application. The product's hygienic performance meets the US FDA and USDA standards, and can be used for packaging food. As the world's factory, China is still in the stage of industrial production with high energy consumption and high emissions. Industrial pollution has become the chief culprit of Chinese-style pollution, and the high-carbon lifestyle of Chinese people is the Achilles heel of Chinese-style pollution. It can be seen that my country is facing The environmental issue is a social issue. The widespread use of POF heat shrinkable film in the Chinese packaging market fully reflects China’s emphasis on environmental protection, and also reflects the improvement of modern people’s environmental awareness and overall quality. POF heat shrinkable film is a functional and environmentally friendly The combined plastic packaging film has superior airtightness, high transparency and gloss, strong tear resistance, and excellent cold resistance. The most prominent feature is its environmental protection performance, which is unmatched by the same type of film. POF heat Shrink film is widely used in the packaging of food and beverage, frozen food, daily chemical products, medical supplies, electronic products and other industries. Production process The three-layer co-extrusion heat shrinkable packaging film is made of linear low density polyethylene (LLDPE) and copolymer polypropylene (TPP, PPC) as the main raw materials, adding necessary additives, and processed by co-extrusion blow molding. The process is different from the traditional blow molding process. Due to the poor tensile properties of PP melt state, the traditional blow molding process cannot be used. Instead, the double bubble process is adopted, which is also known as the Pulandi process in the world. Different extruders are melted and extruded, through a specially designed co-extrusion die head, the primary film is formed and then quenched, and then heated for secondary inflation and stretching to obtain products. POF heat shrinkable film is currently the most widely used and most environmentally friendly packaging film on the market. It is favored by manufacturers and consumers. It opened up the first wave of green packaging in my country. POF heat shrinkable film is gradually replacing PE and PVC equivalent types. Packaging film, occupy the leading position in the packaging film market. The production process of POF heat shrinkable film is non-toxic and consumes less raw materials per unit area. It is an environmentally friendly packaging film with the most development potential and the most market prospects. For more related knowledge, please click:
