The hottest film sticker becomes the mainstream of

  • Detail

Film stickers have become the mainstream of packaging in the 21st century and are playing an increasingly important role in the new metropolis in the 21st century. The development of the situation has brought great changes to the packaging and printing industry and food logistics in history; This is because of the emergence of supermarkets/hypermarkets. In this new century, we are also pleased to see the application of new packaging materials - plastic film. The low price, light weight, short size and easy production and processing of this material have indeed brought a lot of benefits to consumers

★ packaging is sufficient to reflect the development of consumers' lifestyle. It is also helpful to create popularity and make life more and more convenient. This dramatic lifestyle development has actually been going on for many years. Many even increased their efforts for several times because they attached importance to the development of network and e-commerce, and even occupied the territory. This trend has led to the development of new products and new packaging, such as the famous "TV dinner", which is enough to create an innovative lifestyle. With the knowledge of "customer identification" and the process of "deciding to purchase", the "shelf life" in the super market has been changed and the packaging can no longer be changed. The reform of packaging means to focus on the design and appearance. It must have the characteristics of pleasing customers, providing special functions and being convenient to carry. This need for convenience makes it easier for the public to buy, use and discard products

★ film packaging has captured the cosmetics, food and beverage markets. Customers are eager to see the pure and transparent packaging of the product, which makes it look "not like stickers", but film stickers with transparent bottles and plastic containers are more and more popular. Packaging and main stickers must match the appearance of transparent glass. The surface of the sticker, whether bright or hairy, must match the bottle. In food packaging, PP film stickers have become more and more popular in daily necessities, although some UV printing inks have not been approved by the FDA. At present, this problem can be solved by coating a thin layer of PP film micron on UV printing ink, so that food can be contacted and harmless. Pet has replaced many glass bottles, but it is likely to reduce the use of glass in Europe by 25% by 2020. More environmentally conscious PET bottles and cans will be more likely to replace aluminum beer bottles. The beer market will be replaced by PET beer bottles in the near future. This is because new multilayer pet has been successfully developed after adding nylon to form stronger properties. The new plasma coating technology can also solve the problem of low temperature sterilization resistance of PET bottles. PET beer bottles have been imported into three factories in heinegan, the Netherlands, Miller, the United States and calden, Australia

★ the application of plastic film continues to rise. In the 1990s, the use of film in Europe was amazing, especially PP, pet and PE. PE is mostly used for film printing because of its extrudability. However, under the requirement of cost reduction, PE film stickers can not be made thinner without losing their nature. New and more expensive materials can obtain better processability without losing their properties. Pet is not widely used because of its high price. However, due to its durability and heat resistance, it is widely used in A4 laser printers, VIP stickers and other stickers that need its characteristics. The near perfect property makes PP take the lead in the application of film stickers. Its continued popularity is due to the transparency, processability and stability of PP. The only problem is its "non extrudability", so PP will not be able to replace PE in some applications. The biggest challenge in the industry is to develop a material between PP and PE. So far, many companies have developed it, but the market is still waiting for its best product

★ 1 the pointer of the experimental machine must be set to zero. The European Union (EC) has begun to dominate the packaging and its waste. Creative packaging is closely related to the raw materials, their chemical composition and environmental protection issues. In 1994, the European Union announced that a new manager would be added to the packaging and its waste. Its purpose is only to set the goal of recycling and reuse in order to reduce the burying of packaging. According to its statement, packaging waste must be recycled and reused in 2001. In 1998, 40% of the packaging waste was recycled and 8% was recycled. By 2001, the recycling proportion must reach% and at least 15% of the% must be recycled to the original packaging material. This legislation enables EC management personnel to set up real environmental protection supporting material utilization simulation, performance evaluation, risk analysis and technical demonstration books for manufacturers, users and Throwers in accordance with the 1997 packaging waste regulation (Pror)

★ responsible for environmental protection. As the demand for energy conservation continues to rise, the packaging industry must consider the direction of lighter, reusable and recyclable. In this way, it is necessary to upgrade to a new concept, that is, both convenience and economy should be taken into account. Lighter packaging can be developed by using thinner materials or different forms of packaging. According to statistics, packaging materials have been reduced by 28% on average compared with 10 years ago, that is, 1.8 million tons of materials have been reduced. Most of the restrictions on the use of film sticker materials are on the machines that handle their characteristics. At present, there has been positive development. It is expected that the surface and inner materials will be more than 50% thinner than now in a few years. Repeated use of packaging is a way to enhance the future of material efficiency. Reusable packaging such as PET bottles and non food bottles and cans are used in liquid packaging and industrial transportation packaging to make them have "fire performance" that can avoid material flashover. About 1.5 million tons of plastic packaging are recycled every year, not much in food, because of the health regulations, but new technologies will provide new possibilities. Therefore, the use of recycled materials is meaningful. The best packaging is entirely made of man-made materials
