The advantages of plastic soft packaging are: light quality, soft, less waste, small space, low cost and cost effectiveness (volume and weight per unit weight package), so it is more competitive than hard packing. The direction of plastic material development is to improve performance, reduce cost and be beneficial to environmental protection.

 

 

With the development of new plastic varieties and new brands, processing technology and mechanical improvement, the performance of materials and packaging products can be improved, which can not only reduce material consumption and cost, but also meet the requirements of the environment.

 

 

According to the Research Report of the European plastics manufacturer association (APME), the average weight of the plastic used for packaging has fallen by 28% in the last ten years, reducing the amount of more than 1 million 800 thousand tons per year and saving the resources. The plastic packaging film is the most effective, accounting for more than 70% of the savings, and the annual consumption of packaging materials in Europe is 66 million 400 thousand tons, of which plastic is plastic. 11 million 600 thousand tons, accounting for 17%, accounting for 50%.

 

 

Therefore, it can be said that plastic, especially plastic soft packaging is the most effective way to reduce the weight of packaging, reducing the weight or even more than the recycling amount (1 million 500 thousand tons per year), the rational use of resources plays the most important role.

 

 

When it comes to the importance of plastic soft packaging in food packaging, the German plastic magazine has pointed out that it has become a part of the culture. Besides the packaging, it can prevent the damage of the package, reduce the requirements for the storage, provide the information to the consumers, serve the customers more effectively, make the goods convenient for the family management, Easy to store and transport. This point can be expressed as follows: the food of 30%-50% in developing countries is damaged in storage and transportation, and the developed countries in Western Europe are currently only one of the fastest growing varieties in the packaging of the 1%-2%. plastic soft packaging market because of their good comprehensive performance and price ratio of plastic soft packaging.

 

 

It can be seen that the average annual growth rate of plastic soft packaging is higher than that of other packaging methods in the past and last, not only faster than paper packaging, but also higher than plastic hard packing. The data provided by the famous American business communications company (BCC) in the "plastic soft packaging industry of the changed public" is that the total amount of the world plastic soft packaging market is only 6 million 310 thousand tons in 2001, and the largest amount is food packaging, which is 1 million 680 thousand tons.

 

 

In a word, the colorful plastic soft packaging, with its excellent comprehensive performance, continuously replace other packaging, and has become the fastest growing product in the packaging industry. It is expected to maintain a good growth momentum in the next few years.

 

 

In order to improve market competitiveness, plastic flexible packaging will develop towards thin wall and high performance. The demand for multilayer composite membrane will increase faster than ordinary single layer membrane. The development of new plastic grades and processing technology advances the progress of plastic soft packaging technology. Polyethylene film and biaxially stretched polypropene film have the most promising application prospect in packaging.
