Talking about the Change and Thinking of Washing Powder Packaging Materials

Washing powder developed in China with the development of petrochemical industry. In 1958, the first package of detergent was produced in Shanghai, the popularity of washing machines and the transformation of the concept of laundry in the countryside, so that the output of washing powder increased year by year. So far, China's detergent production has reached more than 3 million tons. When the product comes out, it also brings in the use of packaging materials. According to preliminary estimates, the direct consumption of packaging materials in the detergent industry is more than 2 billion yuan. In the past decade or so, changes in the market, changes in people’s aesthetics, and fierce market competition have caused many changes in the internal and external packaging materials and packaging processes of laundry detergent. Although the requirements for packaging of laundry detergent products are not very high, some traces or history of the development of the packaging industry in China can be seen from the evolution of the use of laundry detergent packaging materials.

1, the evolution of washing powder packaging

Inner packaging, also called small packaging, single packaging. After washing powder was produced in China, its packaging form also followed recently. Due to the poor printing conditions in the country, the use of color was monotonous and printed directly on the polyethylene film used. The detergent component contains a surfactant. After it meets water, it has a certain emulsification effect on the ink, which will make the packaging bag show a "flower face" phenomenon. In the era of planned economy at that time, the commercial nature of the product had not been raised, and few people had complained about it. With the addition of detergent, soap, and other daily necessities, the goods have continued for nearly 30 years. During this time, many companies also studied packaging materials, such as Shanghai, Nanjing, and other companies have tried to use paper instead of plastic film. Later, due to the factors such as easy absorption of moisture and agglomeration of laundry detergent, the cost of adding paper is high. Not easy to seal, etc., caused this new life to die.

In the 1980s, the printing industry made great progress. The emergence of printing technology, blown film technology, and various types of plastic films enabled the use of composite film packaging materials in laundry detergent packaging. Due to the fact that the cost and the market are not sensitive to this, it is not widely used. It is only used in products where the content requires relatively high packaging materials, such as concentrated laundry detergent, because its alkalinity is relatively high, it is easy to agglomerate, and appearance High density, single-film plastic film can no longer meet the requirements. The large-scale use of composite films in detergent powder bags was really in the 1990s. As the market gradually develops towards the direction of the market economy, the advantages of the technology of composite membranes have been recognized by the market through reform and opening up. In fact, the market has promoted the application and development of this technology. Composite membrane technology has unique advantages in the application of detergent powder packaging bags. Firstly, the phenomenon of ink discoloration is completely avoided when the composite layer of plastic film is applied on the surface of the printing layer, so that the use of color can be avoided. Restrictions, the introduction of printing equipment, the improvement of platemaking technology, and the use of computers have greatly improved the accuracy of chromatography, and thus the completed bags have greatly improved the product's commercial properties, and the scale effect of petrochemicals has enabled various The cost of plastic materials has been greatly reduced. This has also created favorable conditions for the promotion of composite film plastic bags. Currently, detergent powder bags on the domestic market use a large number of such composite films.

Although the composite membrane material is good and the cost is low, it has its own inadequacies. Now, the paper promotes the protection of the environment and protects our planet. The easily biodegradable material—paper packaging is still one of the most environmentally friendly materials. Box packaging is very common, but in our country is basically some of the more upscale detergent used this form of packaging, the low price competition of the domestic detergent to make use of this packaging material has been affected.

2, the evolution of washing powder packaging

The outer packaging, that is, the large package, is basically in the form of a carton just like other industries. Until the late 1990s, this form of packaging has undergone a qualitative change. It can be said that an abnormal imagination has occurred and companies have adopted a method that is not easily biodegradable due to cost considerations. Some woven bags made of polypropylene film, some directly use a thicker polyethylene film. The current large-scale detergent packaging on the market uses this type of packaging, and the impact on the environment is difficult to estimate.

3, the development and thinking of washing powder packaging materials

The packaging industry of detergent industry should eventually develop in accordance with the requirements of the development of the times. The application of new materials and technologies is a topic that should be studied by packaging developers in the industry for a long time. Green packaging is always a goal pursued. The transitional competition of enterprises in terms of products has affected the development momentum of enterprises, reduced the investment of enterprises in scientific research, and the competition at low prices has caused enterprises to put environmental protection and other issues behind them, along with the sound laws and regulations of China. Implementation, I believe this abnormal phenomenon will gradually improve. However, as far as the current situation is concerned, there are some problems in the packaging of laundry detergent, such as small packaging specifications, less investment in the application of packaging materials, and less investment in automatic packaging. Therefore, it is hoped that more new materials will be introduced in the packaging industry, more advanced printing technologies will be applied, more environmentally friendly and low-cost materials will be available, and the government will be able to spend more efforts to support the promotion and application of new materials. The use of materials that are conducive to environmental protection will be limited, so that through the efforts of the entire society, in the near future, it will be more than just the packaging of the detergent industry. It is believed that the entire packaging industry will be healthier and better.
