Recently, the AQSIQ and the National Standards Commission issued a newly revised series of national standards for "Express Delivery Packages". Greening is the top priority for this new national standard revision. The new national standard clearly recommends the use of low-weight, high-strength raw materials for production. It has proposed reductions and lighter weight requirements for consumables and has become one of the focuses of the revision of the national standard.

 

The author finds that the new national standard has obvious "lean" tendencies. The thickness of the courier bag was reduced to a single layer of 0.03 mm, a reduction of more than 50%; the raw material quantity of the envelope was not less than 200 grams, a decrease of more than 20%. Why does the new national standard boldly implement a "slimming plan"? The author believes that this is mainly due to the following considerations.

 

First, thickness is no longer the sole criterion for testing the performance of plastic bags. In the past, China's testing equipment and technology were backward. We believe that only courier bags with a thickness of 0.06 mm or more can meet the high-strength requirements of the express delivery industry. Now evaluate the performance standards of a courier bag, mainly through the toughness (stretching rate), breaking strength, burst resistance (piercing resistance) and other performance indicators, not just the thickness. Experiments show that some thin plastic bags far exceed the thick plastic bags in the above performance indicators. The so-called courier bags sold in the market to reach the national standard thickness are often made of recycled materials and limestone, which cannot meet the requirements of the express delivery industry.

 

Secondly, the application of new formulas and new technologies has enabled plastic bags with a thickness of less than 0.06 mm, both in terms of performance and test indicators, to be much higher than 0.06 mm plastic bags. For example, a new material plastic bag developed by some companies adopts a thickness of 0.035-0.045 mm, reaching or even exceeding the actual use effect of the national standard of 0.06 mm.

 

Third, reducing the quantitative requirements for plastic bags and jackets will help reduce the waste of raw materials, encourage technological innovations such as raw materials and processes, and boost the development of energy-saving, environmental-friendly, cost-effective enterprises. As we all know, the thicker the plastic bag, the more plastic pellets (PE material) are used, the thickness is reduced by half, and the used plastic pellets are also halved accordingly, thereby minimizing dependence on petroleum resources and reducing environmental pollution. The reduction in thickness standards has enabled Shenzhen printing companies to reduce the cost of raw materials, and to work hard on the strength, performance, and user experience of consumables.

 

Fourth, to meet the lightweight requirements of express delivery. The reduction in the thickness of courier packaging will reduce the weight accordingly, which is particularly important in the cross-border e-commerce and air transport sectors. According to calculation by an authoritative organization, from China's air cargo shipment to the United States or Europe, if the weight of a certain item is reduced, a reduction of 1 gram in packaging materials will reduce the transportation cost by 7.5 points. Lighter materials will help reduce delivery costs and benefit consumers.

 

Fifth, refer to international practice. Before the new national standard was introduced, the quantitative requirements for express envelope materials in China were generally 250-300 grams. Some good-quality envelopes even used 400 grams of cow cardboard and 600 grams of corrugated cardboard. However, there are only 200 grams of envelopes in many foreign countries and they are intact in the shipment. This kind of weight can be reduced by 155,000 tons to 310,000 tons of paper each year based on the use of 3.105 billion envelopes per year.

 

Undoubtedly, the introduction of the new national standard will help printing and packaging companies invest more energy in the research and development of new technologies and new materials, and prevent companies from seizing the market with low-quality and low-cost products, and fall into the red sea of price wars.
