Quantitatively packaged goods are short of catties? Enterprise self-reflection and self-correction?
01 Hot spot tracking
◆ Recently, Ms. Li, a Beijing resident, exposed a shopping experience on social media in that "the purchased product does not match the pre-sold product".She only received 86 of the 150 garbage bags she purchased, which has attracted widespread attention.But this is not an isolated example, as many consumers have similar problems when purchasing quantitatively packaged goods.
◆When shopping, consumers often can only rely on the quantity marked by the merchant to determine the authenticity of the product. However, after receiving the product, the phenomenon of reduced shrinkage occasionally occurs, which is difficult for consumers to distinguish. For example, for diapers labeled with 50 pieces, only 38 pieces are available; The so-called 100 sheets of paper towels are actually less than 80 sheets; Even buying a box of oranges, only one of which fits the description. These phenomena make consumers feel helpless and angry!
02 Current Situation of Quantitative Packaging Commodity Market
◆ Quantitatively packaged goods - refer to pre-packaged goods with unified identification content such as quality, volume, length, area, and counting within a certain quantity limit.
◆ This is not the first time that the actual quantity or weight of quantitatively packaged goods does not match the labeled information. The survey results released by the Beijing Consumer Association in September 2018 showed that 10 out of 49 quantitatively packaged products did not meet the standard requirements, and nearly 20% of the products had issues with weight shortage.
◆ According to the notice from the State Administration for Market Regulation, a special inspection on the measurement and supervision of the net content of quantitatively packaged goods was carried out in nine provinces including Tianjin, Hebei, and Heilongjiang in 2021. A total of 431 enterprises were randomly inspected, with 987 batches of quantitatively packaged goods. Among them, the net content labeling of products such as rice, flour, shampoo, and cosmetics had a sampling qualification rate of 96.6%.
◆ Under relevant regulations such as the "Measures for the Supervision and Management of Quantitative Packaging Commodity Measurement", in real life, the measurement equipment is not accurate enough, the measurement methods are not perfect enough, the professional abilities of measurement operators are different, and environmental factors such as weather, temperature, and humidity are considered. Quantitatively packaged goods are allowed to have a slight "weight shortage", but the difference between the marked net content and the actual content must not exceed the specified allowable shortage quantity.
03 Increase regulatory efforts and raise the requirements for entry barriers
◆ Chen Yinjiang, Deputy Secretary General of the Consumer Rights Protection Law Research Association of the China Law Society, stated that the issue of insufficient weight and shortage of quantitatively packaged goods is widespread and hidden, infringing on the legitimate rights and interests of many consumers.
◆ This chaos is mainly due to the lack of integrity and legal awareness among some operators, who seek improper economic benefits by reducing costs through a lack of weight. To root out this problem, production and sales enterprises should consciously enhance their sense of main responsibility, improve their metrological assurance ability and product quality, strengthen internal supervision and spot checks, and improve the quality of management personnel, in order to eliminate the act of lacking weight and cutting corners from the source.
04 “A good helper” for quantitatively packaged goods
◆ Of course, some non-compliant products may be due to inaccurate measurement equipment, incomplete measurement methods, insufficient professional skills of measurement operators, as well as environmental factors such as weather, temperature, humidity, etc., resulting in very few quantitative products being "lacking in weight".
◆ In response to this situation, Guangdong Kenwei Intellectualized Machinery Co., Ltd. company's professional research and development of a quantitative combination of weighing and packaging equipment suitable for various materials in various industries can effectively solve the problems of inaccurate weighing, material leakage, and insufficient storage caused by various objective factors. It can effectively improve the production efficiency of weighing packaging while ensuring accurate weighing, saving time and effort, and making it convenient and fast!
