POF heat shrinkable film contributes to environmental protection

With the increasing pressure on the environment on a global scale, the Chinese government has continuously strengthened its environmental protection supervision efforts. More and more cities will join the ranks of charging for air pollutant emissions; and it stems from the awakening of consumers’ awareness of green environmental protection. Packaging has become a manifestation of the soft power of commercial competition. In the new year, more companies will follow the principle of '4R1D' (low consumption, development of new green materials, reuse, recycling, and degradability), in terms of green materials, energy-saving and consumption-reducing equipment, clean production processes, waste Speed u200bu200bup the research and development, application and promotion of recycling and processing technologies. In 2016, the industry will speed up the establishment, improvement and introduction of a wider range of green printing standards and green printing evaluation systems, and will include more outstanding packaging companies in the standard construction and system certification. While the government strengthens environmental protection supervision and eliminates outdated production capacity, it is bound to strengthen green printing policy guidance and provide greater policy support for enterprises to implement green printing. POF actually means heat shrinkable film. The full name of POF is a multi-layer co-extruded polyolefin heat shrinkable film. It uses polyethylene as the middle layer and co-polypropylene as the inner and outer layers. It is plasticized and based on an extruder, and then passed through a mold. It is processed by special supply such as head molding, so it has the characteristics of high transparency, strong sealing, good shrinkage, strong tear resistance, etc., suitable for packaging in various fields, such as food packaging, daily necessities packaging, industrial packaging, etc. . In the 21st century where energy saving and emission reduction, green and environmental protection are the key words, the concept of energy saving and environmental protection is deeply rooted in the hearts of the people and permeates all major fields. The concept of energy saving and environmental protection of POF heat shrinkable film is combined with the production concept to bring convenience in our production and life. At the same time, it does not cause pollution and burden to the environment, and enters our lives with the characteristics of energy saving, environmental protection, and excellent packaging effect, adding a touch of 'green vitality' to the packaging market. POF shrink film is the only certified environmental protection packaging film in the United States and other European and American countries. POF heat shrink film is a replacement product of traditional packaging film. It is a new generation of environmental protection, transparent gloss, strong sealing, strong cold resistance, and excellent flexibility. Ideal packaging film. Heat shrinkable film can be used for product sales and transportation. The main function is to protect the goods. Heat shrinkable film is a good packaging material, but how to store it when it is not used normally? The heat shrinkable film manufacturers give you an analysis. 1. When storing the heat shrinkable film, it should not be placed in a place that is too dry or exposed to direct sunlight. The temperature should be kept at about 50 degrees. 2. The heat shrinkable film manufacturer tells everyone that because the heat shrinkable film shrinks when exposed to heat, do not store the heat shrinkable film in a place where the temperature is too high. 3. No matter what the product is, it will have a shelf life. If it exceeds the shelf life, the effect will not be so good when used. The same is true for heat shrinkable film. Pay more attention to it. Shrink film is also a kind of packaging film, which can be used to pack regular and irregular items, and it has a good protective effect on the items. Sometimes when we buy pof shrink film, the price is usually different, shrink film The manufacturer will explain why. Reason 1: The material is different. In the production of pof shrink film, most of them are made of polyethylene as the middle layer and polypropylene as the inner and outer layers. If the materials used are not these two, the price of the shrink film will be affected. Reason two: the quality is different. Pof shrink film manufacturers tell everyone that the main reason why the quality of shrink film is different is that the production process of shrink film is different. If the production process is relatively complete, then the quality of the shrink film must be guaranteed. Reason three: different manufacturers. Nowadays, there are many manufacturers that produce pof shrink film. The shrink films produced by different manufacturers are different in all aspects, which also causes the different prices of pof shrink film. The environmentally friendly multi-layer co-extruded polyolefin POF shrink film uses linear low-density polyethylene (LLDPE) as the middle layer and co-polypropylene (PP) as the inner and outer layers in a special equipment. The inner, middle and outer layers are separated by a special process. The three layers are co-extruded to produce a heat-shrinkable film with high transparency, high shrinkage and good heat sealing performance. The shrinkage temperature of POF shrink film is generally 150 degrees. The setting of the temperature difference depends on the shrinking furnace itself. A good shrinking furnace can shrink at about 120 degrees. Old-fashioned heating tube shrinking furnaces must be set to 200 degrees to shrink. There is a process for the product to enter thermal shrinkage. Generally, it is heated first, then expands and then shrinks, and finally comes out. There is a cooling time, so choosing a shrinking furnace is the key. For shrinking films of different materials, you can choose shrinking furnaces with different functions. When shrinking, the shrinking film should be vented according to the different conditions of the product, so that the internal gas can escape during shrinking. Come out. It will not bulge up due to gas inside after shrinking, which will affect the appearance. POF environmentally friendly heat shrinkable film is best to choose a constant temperature shrinking furnace with a temperature cycle in the furnace, so as to avoid uneven heating of the product during the shrinking process and affecting the shrinking effect.
