Liquid packaging relies more on plastic bottles (Part 1)

over the years, with the increasingly perfect performance of pet and HDPE materials, the aseptic filling technology adopted by beverage manufacturers has become more and more mature; Thus, higher requirements are put forward for other peripheral equipment besides filling technology, such as integration and ease of use. For many beverage manufacturers, the introduction of new aseptic technology in product production means a great market opportunity, of course, is also a great challenge

aseptic filling

more and more beverages, such as juice, non carbonated beverages, iced tea, coffee, sports drinks, purified water, and pasteurized milk, must maintain good antibacterial properties during the filling process. In recent years, more and more PET bottles or PP and HDPE bottles are used as containers for these drinks. Some experts predict that in the next few years, the PET bottle aseptic filling market will increase at twice the current rate

aseptic filling of plastic bottles must include the sterilization process of contents, bottle body and bottle cap respectively, and at the same time, the three should be combined in a sterile environment. The disinfection of contents is usually carried out in a short time of high temperature environment. The sterilized bottle cap can be made of multi-layer materials, or it can be a screw cap with plastic. Usually, the disinfection method of disinfection pool or UV sterilization is adopted

if the enterprise assumes that the machine selects aseptic filling in the standby mode, it means that it also has to invest a lot of money in the whole disinfection system. It must combine disinfection with a more assured flushing system. In this series of links, how to keep containers from actively expanding the research and development of new materials in aerospace, national defense industry, rail transit, deep-sea operation and other fields to the sealing and quality assurance in the aseptic packaging process is the most important issue for all enterprises. In recent years, the space for container drying on the equipment has become smaller and smaller, because it is believed that the smaller the drying space, the smaller the risk of container being affected by bacteria. People have different opinions on the specific drying methods

in this year's Drinktec2005, the two different drying methods adopted the wet drying method with over acidity and the dry drying method with hydrogen peroxide, both showing their own characteristics in terms of efficiency and safety. For example, the dry drying method uses the steam flow of hydrogen peroxide. After a very short drying process, the container can be dried immediately in the disinfection hood

system integration

it can be seen that the aseptic packaging process is reflected not only in filling, but also in the whole process. This requires the whole system to be well integrated, including the selection of disinfectant or toxic gas, the pre cleaning of disinfection devices, the preparation and storage of beverage raw materials, etc. the automatic control system and detection device can make the whole processing process realize visual operation, analysis and quality management with traceable detectors

on the other hand, if the aseptic filling production line needs to be repaired, the technicians must be trained or qualified accordingly. In short, the effect of aseptic processing is related to each link of the whole process

aseptic filling of milk

drinktec2005 is the first exhibition that Drinktec has paid attention to milk products or related marginal fields since its inception. Because milk needs to be kept in aseptic packaging for a long time, aseptic filling is undoubtedly the most interesting part of the production line. Driven by the increasing expectations of consumers and food innovation, plastic containers are gradually used for milk products. It is understood that about 30% of milk products have now adopted plastic containers. As for aseptic filling of PET bottles, they are mainly used in UHT milk products, which can be stored at room temperature for up to three months

in a word, the aseptic filling technology and product quality of beverages and milk packed in cartons or plastic bottles will continue to improve with the improvement of consumer demand

bottle labeling solution

the packaging of beverages not only needs attractive appearance design, but also needs a personalized and unique packaging form. For the beverage packaging container, the label plays a very important role. It can remind consumers of the important information of the beverage, such as production date, beverage composition, etc. As people pay more and more attention to the importance of bottle label, while the production technology of beverage and its container continues to develop, the labeling equipment and related processes have also made great progress. On the one hand, the flexibility of the production mode has been improved, so that the forming temperature should be strictly controlled. One equipment can process a variety of labels; However, it must be pointed out that the humanized design of the machine is particularly important for flexibility. On the other hand, the performance of the equipment is also improving

diversity of label materials

with the increasing variety of bottle bodies in the market, the corresponding label varieties also show a diversified situation. For glass bottles, paper labels are mainly used, which are attached to the bottle body, the back, or the bottleneck. In terms of technology, the common printing methods of paper labels are offset printing and rotary gravure printing. All production parameters, such as printing tension, printing speed, pasting speed and bottle pasting speed, need to be set correctly; In addition, it is also necessary to consider how to improve the adhesion between the label and the bottle body, and how to make it easier for the bottle washer to clean the residual label. In terms of label design, brighter colors will be adopted to present a more shiny and even metallic surface effect. Paper labels can also be used on plastic bottles, or only on the front, or as winding labels

the labels on the bottles of spirits or other spirits are mostly wet glue labels, which are characterized by no label; Now, many beer bottles are also using such labels

on other plastic bottles, the application of film labels has become more and more popular, and hot melt adhesive is used to adhere the label head and tail. The use of heat shrinkable sleeve labels on plastic bottles is the main development trend in the future. Covering the whole bottle with labels can not only perfectly reflect the advertising image of products, but also bring consumers more information tips
