Factors affecting the quality of roof packages

During their daily visits to dairy companies, the reporter often heard comments on the problems of bagging and leakage of paper packaging in dairy products packaging. Due to the repeated occurrence of these problems, the quality of products may even affect the corporate image. Enterprises will generally take measures such as changing suppliers, multi-sourcing, or adjusting filling equipment, but they still cannot fundamentally solve the problem. Recently, the reporter visited Potlatch's office in Beijing and requested the head of its sales and technical department to discuss from the perspective of the cardboard supplier what factors affect the quality of the carton.
Potlatch is a 35-year-old cardboard supplier. Although it has established an office in China for only half a year, most of the domestic manufacturers, including Gulin, Global, Quanhua, etc., are purchasing their milk cardboard. For production of "roof packaging". For the headache and bloating problems of roof packages that plagued dairy companies, Yu Xin, Technical Department Manager explained that this has something to do with board weight, die-cut quality, heat-sealing temperature, and accuracy of filling equipment. Dairy packaging boxes should be based on the different needs of the user and filling choose different weight cardboard, for example, long shelf life requirements should choose a thicker cardboard, short can be thinner; die cutting is a key factor in the expansion of the carton package , It is directly related to the appearance of the tray is founder, milk box die-cutting requires different depth of each indentation, which is not easy to control the flat die-cutting die-cutting machine, while the round pressure die-cutting machine although the effect is good but the price The quality of heat sealing not only carton manufacturers should pay attention to, dairy enterprises should also pay attention to the production, the heat sealing temperature is too high or too low are the causes of milk leakage, coupled with the domestic carton production companies due to capital, cost The reason is often to select relatively low-grade processing equipment such as die-cutting machines and heat-sealing machines, and it is not surprising that products have problems. Yu Yu said that although there are many carton manufacturers in China, they are still at the stage of exploration in terms of production technology, technology, and experience, resulting in a shortage of products compared with foreign advanced levels. This situation has led many dairy companies to consider only a handful of well-known companies' products when purchasing roof packs. They cannot conduct multi-factory inspections and convenient local purchases just like plastic bags (cartridges) or cartons. In order to achieve the goal of localized procurement of roofing materials, Potlatch, which is in the promotion period, often provides technical cooperation including product development technology sharing, paper product conversion technical support, and golden ideas to the cartons supplier that it is cooperating with. service. In order to be able to cultivate a batch of qualified roofing packaging suppliers distributed throughout the country, to bring more choices for dairy companies.
Sales Manager Jiang Jianbo told the reporter that the current situation in China has confirmed the optimistic prospects of paper packaging, especially “roof packaging”, in many respects. First, consumer demand has determined the change in dairy packaging structure to freshness, after some adjustments, fresh-keeping packaging. Can greatly improve the shelf life; Second, with the rapid development of refrigeration conditions and supermarkets, the external conditions required for fresh-keeping packaging is getting better and better; Third, people's awareness of environmental protection is increasing, the demand for the application of biodegradable packaging materials increased, some large Cities from the perspective of urban governance will limit the use of packaging materials such as plastics. But at the same time, there are some misunderstandings in the use of roof-type packaging materials by dairy companies: for example, blindly stressing the weight of the carton, not knowing and mastering the scientific inspection methods for the acceptance of the carton, etc. Therefore, Jiang believes that both the dairy industry and its related industries should be standardized within the industry as soon as possible, and should be in line with international advanced management methods and concepts. Otherwise, neither side can achieve greater development. (Leading) ("Milk, Drink Packing")
