Aseptic filling more and more beverages, such as juice, non-carbonated beverages, ice tea, coffee, sports drinks, purified water, Pakistan-style sterilized milk, etc., must maintain good antibacterial properties during the filling process. In recent years, these beverages increasingly use PET bottles or PP and HDPE bottles as containers. Some experts predict that in the next few years, the aseptic filling market for PET bottles will increase at twice the current rate.
Aseptic filling of plastic bottles necessarily includes the disinfection of the contents, the bottles and the caps, respectively, while also combining the three in a sterile environment. Sterilization of the contents is usually performed in a short period of high temperature environment. Disinfected bottle caps can be multi-layer materials, or they can be plastic screw caps. They are usually sterilized using a disinfection tank or UV sterilization.
If the company chooses aseptic filling, it means that a large amount of money must be invested in the entire disinfection system. The disinfection and washing system must be combined. In this series of links, how to maintain the tightness and shelf-life of containers from sterilization to aseptic packaging is the most important issue for all companies. In recent years, the space used for container drying on equipment is getting smaller and smaller, because everyone thinks that the smaller the drying space is, the smaller the risk of the container being affected by bacteria. For the specific drying method, people's opinions are also different.
In this Drinktec2005, these two different drying methods - the use of an acidic wet-drying method and a dry-drying method using hydrogen peroxide, have demonstrated their respective characteristics in terms of efficiency and safety. For dry drying methods, a stream of hydrogen peroxide is used. After a very short drying process, the container can be dried immediately in the sterile hood.
System integration 
This shows that the sterility of the packaging process is not only in terms of filling, it is reflected in the entire process. This requires the entire system to have good integration, including the selection of disinfectant or disinfecting gas, pre-cleaning of the disinfecting device, preparation and storage of beverage raw materials, etc., and the automated control system and detection device can visualize the entire process. Operations, online analysis, and quality management with traceability detectors.
On the other hand, if an aseptic filling line needs to be repaired, the technician must be appropriately trained or qualified. In short, the effect of aseptic processing is related to every aspect of the entire process.
Aseptic filling of milk Drinktec2005 is the first exhibition that Drinktec has been focusing on in the field of dairy products or related fringes since its creation. Because milk needs to be stored in a sterile packaging environment for a long time, aseptic filling is undoubtedly the most interesting aspect of the production line components. With the increasing expectations of consumers and the drive for food innovation, milk products have gradually started to use plastic containers. It is understood that about 30% of milk products are now plastic containers. For the aseptic filling of PET bottles, they are mainly used in UHT milk products, and they can be stored for up to three months at room temperature.
In short, the quality of aseptic filling technology and products will continue to increase with the increase in consumer demand, whether in cartons of beverages and milk, or in plastic bottles.
Bottle labeling solutions The packaging of beverages not only requires an attractive exterior design, but also requires individualized and unique packaging. For packaging containers for beverages, the label plays a very important role. It can convey important information about the beverage, such as the date of production, the composition of the beverage, etc., to the consumer. As people pay more and more attention to the importance of the label of the bottle body, the labeling equipment and related processes have also made great progress while the beverage and its container production technology are continuously developing. On the one hand, the flexibility of production methods is improved, so that a single device can process a variety of tags; however, it must be pointed out that the humanized design of machines is particularly important for flexibility. On the other hand, the performance of the equipment is also constantly improving.
The diversity of label materials has continued to increase with the variety of bottle types on the market, resulting in a variety of label varieties. For glass bottles, paper labels are mainly used, either on the bottle body, or on the back, or at the bottleneck. In terms of technology, the common printing methods for paper labels are offset printing and rotogravure. All production parameters, such as printing tension, printing speed, pasting speed, and bottle placement speed, need to be set correctly. In addition, how to make labels and bottles Better adhesiveness and easier washing of residue labels in bottle washers also need to be considered. In terms of label design, brighter shades will be used to provide a more glossy and even metallic finish. Paper labels can also be used on plastic bottles, just on the front, or wrapped around labels.
The label on the bottles of spirits or other alcoholic beverages is mostly a wet glue label. Its prominent feature is the “no-tag feelingâ€; now, many beer bottles have begun to use such labels.
On other plastic bottles, the use of film labels has become more and more popular. Hot melt adhesives are used to block the head and tail of labels. The use of heat-shrink sleeve labels on plastic bottles is a major development trend in the future. Covering the entire bottle with labels will not only perfectly reflect the product's advertising image, but also give consumers more information.
High-yield rate has become a trend Now, the continuous increase in the output rate of plastic bottle-wound labels has become a very significant trend. For film labels using hot melt adhesive and paper labels using cold glue, the labeling speed has reached 70,000 bottles per hour, ie 20 bottles per second. In order to meet the production requirements for shrink sleeves, the manufacturing industry has produced rotating or wired labeling equipment.
Drinktec2005 built a display platform for beverage labeling solutions. Manufacturers not only brought in various types of label materials including smart labels, micro-tags, and electronic labels, but also demonstrated various advanced labeling processes.
The versatility of the equipment 
Beverage manufacturers need not only one label, but on the contrary, the type and style of the label must correspond to the product. Sometimes, the label of a bottle of a beverage not only shrinks the sleeve label, but also has an overall body and a bottleneck. Then, what kind of solutions do the labeling equipment manufacturers need to provide to meet the needs of the company?
The key point is that the equipment should have a modular structure. Because this can make a machine a versatile production tool, and a variety of solutions can be converted to each other. For example, in the labeling process, you can choose whether to use cold glue or hot melt glue. In short, if the device's labeling scheme is diversified, flexibility can be maximized in label design. Using a device with a modular structure not only saves the cost of purchasing other equipment, but also greatly simplifies the complexity of the transfer and connection work between multiple processes. In addition, the integration of multiple devices on one device also greatly reduces the space occupied by all devices.
Bottle cap is the protagonist
Bottle caps for PET beer bottles In order to meet beer enthusiasts' requirements for high-quality beer, beer brewing companies must not only use PET bottles that have good barrier properties against bacteria, but also require vacuum disinfection of bottle bodies and caps (O2S). Compared to glass bottles with crown-capped beer and PET bottles with vacuum-sterilized bottle caps, there is no material difference between the two. However, PET bottled beer is more refreshing in terms of taste.
The BERICAP double-sealed O2S bottle cap has a very good seal and is one of the best cap choices for PET bottled beer. In order to detect the safety performance of the bottle cap, the bottle body was placed in the highest temperature environment during the simulated transportation process. The BERICAP double-sealed O2S bottle cap showed good sealing performance, even if the beer was stored under poor conditions, the beer The aromatic compounds in the still have good sealing properties, so that their taste will not be greatly affected. Beers with such caps do not affect the quality of their taste even if they are left on the shelf for a long time.
The innovative nature of carbonated beverage caps is now favored by those who have screwed caps; previously, such caps were used only for non-carbonated beverages. In general, sports caps, if light carbonated beverages, in the warm transport environment, CO2 in beverages will not be lost due to the increase of internal stress. However, if it is in a cold storage environment, the bottle body will be deformed due to the loss of internal pressure. Another problem is the aseptic cold filling, which is a problem that almost all companies will encounter. The disinfectant in individual parts of the bottle cap remains after it has been disinfected.
Idee+Form Inc., a sporty “gas-tightâ€, tightens the caps and the new caps offer a new opportunity for beverage manufacturing. Idee+Form company at this Drinktec 2005, for the first time exhibited specifically designed for sports carbonated beverages "gas-tight" screw caps. Even in the aseptic cold filling process, there is no unnecessary pressure inside the bottle body. The cap rotates only one-third of a revolution, allowing consumers to drink smoothly. At present, the bottle cap has 28mm and 38mm specifications.
Menshen Co., Ltd. - "Cool Cap" New Caps In addition, a new type of cap called "Cool Cap" developed by Menshen Company is also attracting attention in Drinktec 2005. The cap is suitable for carbonated or non-carbonated beverage bottles and can also be used on three-dimensional sachets or carton packs. With the one-handed lever principle, the cap is easy to open, and at the same time, because the cap is designed to release the pressure on the side, it also improves the protection for consumers. This kind of bottle cap can be used with ordinary filling production lines and it is also suitable for aseptic cold filling.
Convenient Performance Highlights SimpliDrinkTM Bottle Caps: Minimizing Beverage Spill Risk Seaquist introduced three new cap products at the show. First of all, the bottle lid, called SimpliDrinkTM, not only has a consistent style design with its packaged mineral water, but also minimizes the risk of beverage spillage through streamlined valve plug controls. No matter if it is 0.5 liters or 1 litre of mineral water, it can be opened or tightened with only one hand. At the same time, the double design of the cap ensures the purity and hygiene of the beverage.
Refastenable bottle cap for three-dimensional pouches - SmartSpout
In collaboration with Kapak, Seaquist has also developed a SmartSpout for refastenable caps for three-dimensional pouches. Its unique design is that it greatly simplifies the gripping action and opening action of the cap, and is therefore suitable for use on consumer products for children or the elderly. The use of one-handed caps ensures that even if accidental squeezing occurs on the packaging, no beverage will leak out.
New bottle caps specifically for children's drinks (P'tits Monin) Also, Seaquist has exhibited a new type of bottle cap specially designed for children's drinks (P'tits Monin), shaped like a small animal's head. This rotating bottle cap has a cartoon style that attracts children's attention and is easy to use. Tear off the quality seal, when opening the bottle cap, a soft tongue made of plastic rubber will pop up in the red cartoon mouth of the bottle cap and act as a straw. For example, when the child grasps the tongue and puts it into the cup, the bottle is squeezed and the beverage can smoothly fall from the tongue, which is both hygienic and safe. When the cap is tightened, the tongue is pressed by the cap and the bottle, which is another way of sealing.
Peripheral equipment at a glance As we all know, the performance of the stretch blow molding machine will determine the quality of PET bottles, but at the same time you still need other peripheral equipment to assist.
New Air Compressors In terms of the processing of PET containers, the maximum pressure of a traditional compressor is 40 bar, but this is far from enough. Kaeser introduced the N-series of accelerated compressors at this exhibition. Its power can reach 45 kW, which can reach the required 45 bar pressure in the application. Among them, the N 253-G, N 351-G and N 502-G devices can raise the pressure to 45 bar in the power range from 7.5 to 18.5 kW.
The N-Series accelerated compressors have two-cylinder and three-cylinder engines. They usually start at a low speed from 5 to 13 bar and are then exchanged with air to reach a maximum of 45 bar.
Kaeser Accelerated Compressor
Italy's SIAD also demonstrated the latest air compression technology. The compressor named TEMPO? can compress 90 to 5550 m?/h of air in three stages.
The TEMPOTM series is characterized by easy and quick installation. After combining the mechanics and aerodynamics technologies, the electricity consumption has been reduced by 40%, resulting in significant improvements in energy consumption and mechanical vibration; in addition, the new TEMPO® has saved 15% of the previous product. Space. The new TEMPO® catheters are made of stainless steel.
New design for conveying and testing Italy's MB company is a professional conveyor equipment and system manufacturer in the PET field. The company's delivery system, named Softdrop, can deliver products directly from the injection molding process to a storage warehouse. The system includes timely monitoring software and programs that do not stop production. In addition, it is unique in that it includes a preformed cooling system and a dust cover.
Oxygen detection in PET bottles German PreSens is known for its photochemical oxygen and pH sensing elements. At this PETpoint, the company introduced a system for non-invasive measurement of oxygen in PET bottles. The system, mounted on the inner wall of the PET bottle, emits a blue optical signal through the Fibox measurement system, and the captured signal represents the corresponding oxygen content. Although the measurement process is only three seconds, it has been guaranteed that reliable information can be stored for at least one year. Special air seals prevent the sensing element from being affected by the cap. Although the sensing element is not directly connected to the electronic element, since the sensing element is composed of a single unit, the system can still adapt to long-term detection.
PET Injection Molding Peripherals At this PETpoint, the most significant feature of the injection molding peripherals is the reduction in floor space. Piovan of Italy presented the latest dryer (EMK), which is characterized by the fact that the thermal energy released by the device does not change even when the ambient temperature changes. The specific parameters can be set according to the outside air, and the amount and energy of the drying are all automatically controlled.
For the field of PET, Piovan's biggest innovation is a PLC-controlled integrated feed, heating/drying, molding, and batch filling functions.
Quality Control and Inspection in the Blow Molding Process The PETWall plus VisionTM from AgrTopWave is a system for quality control of the outer wall thickness of PET containers based on an accurate camera inspection system. The outer wall thickness sensor designs four measurement zones for each vessel. Of course, the user can adjust the position. The system uses infrared absorption technology to measure changes in the area being examined, while the camera performs random tests on other, more critical areas such as the bottom of the bottle and the seal. The main content of the test includes whether there are pores, impurities, dark spots, etc., because these will affect the integrity of the container. Convex, concave, nicks, stains, etc. will affect the regularity of the surface of the container.
Introducing this system in the blowing process has many benefits. The biggest advantage is that each bottle can be accurately detected even under high-speed conditions. Through the problem information reported by the system, it is possible to find out exactly where it appears, thus ensuring the normal operation of the production line.
Recycling PET
It is to see the growing market demand for PET, Austria's Starlinger company developed a concept for the "Recostar iV +" PET recycling equipment. The used or preformed PET bottles can be sliced ​​first and then cut into amorphous balls; these resin materials are then drawn into filaments under the action of a solid condenser. This device was fully certified by the FDA in June 2004.
In addition, the same Austrian company EREMA (the world's leading supplier of plastic recycling systems) also introduced a new bottle called bottle-to-bottle (BTB-bottle) that is highly efficient. The economical PET recycling and recycling program can automatically hot-melt the PET filter paper or film base.
Impurity Separation in PET Processing S+S Corporation is a leading company in the plastics manufacturing field dedicated to metal detection and impurity separation. It can provide not only stand-alone equipment but also integrated solutions. The various fields involved include the separation of whole bottles or high-sensitivity PET sheets, especially for the separation of impurities. At this Drinktec 2005, S+S introduced two PET rework solutions: the SPEKTRUM color sorter and the PETMAG metal separator.
The second-generation SPEKTRUM color sorter has greatly improved the identification performance of the color of the raw materials, and the more efficient valves enable accurate classification and classification even for colorless raw materials. In addition, the second level of identification and classification also introduces more integrated technology, reducing the loss of high-quality raw materials. In the recycling of PET, the new operating software makes the process of forming colorless plastics easier. S+S still uses the “Auto-learn†technology on the new generation of SPEKTRUM, which can be programmed into the classification process. The advantages and disadvantages of raw materials, and automatically eliminate inferior materials.
The high-frequency detector of the PETMAG metal separator can detect all kinds of metal impurities regardless of their position or shape in the raw material. PETMAG uses compressed air to remove impurities without mechanical crushing and handling, thus avoiding the risk of machine errors.
Mr. Peter Mayer, Manager of Recycling Department of S+S, commented: “Either SPEKTRUM or PETMAG is a high-quality purification equipment with extraordinary separation technology in the field of PET processingâ€.
The silicification of PET Czech company uses PTP plastic technology to develop an improved technology that avoids the waste of used PET. It has the following meanings:
* Increase the quality of polymer molecular chains;
* Reduce the melt flow index;
* Increase the stretching tension of the molecular tear.
The improved PET molecular chain shows good symmetry with silicone. If it is a low-quality polymer molecule, it will react with the 2, 3, and 4 polar ends of the silicon molecule to make the molecular chain longer or even branched.
This principle has a double effect. On the one hand, low-quality molecular particles can be tightly bound to the PET molecular chain by this method; on the other hand, for the average mass of the polymer, this mechanism allows the resin to be repaired. In addition, this technology allows PET molecules to be combined with PP or PE molecules.
When transporting or storing volatile or combustible materials in bulk bags, it is extremely important to choose static hazard controlling bags to prevent accidental discharges of static electricity. These discharges can cause the materials being transported to combust, leading to potentially fatal situations. A static hazard controlling bag such as the Type D Fibc will prevent static electricity from building up and potentially sparking an explosion.
Unlike other types of static hazard controlling packaging, Type D bags do not need to be grounded before they are filled. This provides a significant advantage in terms of safety because it eliminates the risk of human error. Type C FIBCs must be grounded before they are filled or discharged. In high-volume situations, this can lead to potentially hazardous oversights. Because they do not require grounding, The Type D FIBCs represent the highest level of safety for applications in which bulk bags are used for storing or transporting volatile and/or combustible materials.
