Comparison of two different stretch wrapping film packaging technologies
stretch wrapping film packaging is one of the tray packaging forms, and it is also an ideal way for users. Its working principle is to use the retraction of the tensile film to bind the goods and the pallet into a whole, which plays a fixed role and is convenient for loading, unloading and transportation. At the same time, the fully enclosed outer packaging can prevent dust, moisture and water. The products packaged with stretch wrapping film can be applied to all walks of life, such as chemical industry, papermaking, food, glass bottle making, electronics, medicine, refractory, etc

among the stretch film winding packaging equipment, the pallet packaging line with the fastest speed and the highest degree of automation is the circular and rotating arm system winding film packaging machine, which has a stable market. Most of the world's famous pallet packaging equipment suppliers can provide these two products, Aetna company is one of them
the rotating arm system is more reliable, while the ring system is more waterproof.
Aetna company takes spring water as an example to illustrate that the ring and rotating arm technologies can be used at the same time. S recently announced that six qualified "white list" enterprises, pring water mineral water company, have just purchased the sixth set of rotating arm system winding film packaging machine, but the company still retains a Genesis ring system winding film packaging machine to achieve the speed of pallet packaging and meet the needs of high-speed production of the whole production line. The annular system winding film packaging machine has a large number of detachable accessories, which are often considered to be less reliable than the rotating arm system, But Aetna's mark Tucker said: "If users want to improve the waterproof performance of pallet packaging, it is the same as whether this electromechanical system can give enough power to the relay experimental machine. The effect of installation is the best.
most manufacturers believe that the speed of ring winding packaging machine is higher.
in terms of speed, the speed of a ring winding packaging machine can reach 120 discs/hour. It is also because of its fast speed that retailers prefer to use ring winding packaging machine." The system packs European style small pallets. "Orion packaging systems is also interested in manufacturing stretch winding film packaging machines with ring systems. The recently launched A800 series is one of its autoline series equipment with higher speed. Ann Williams, director of Orion company, said, "the A800 series winding film packaging machine can set procedures according to different needs, which can pack light and fragile goods or heavy goods, and the speed can reach 120 discs/hour."
MJ Maillis has been selling mancon series ring packaging machines in the UK. Now, this series of 2201 has added new performance. It is said that its advantages are easy to install and low production cost. Steve Bates, the sales manager of the stretch film department, pointed out that the stretch winding film packaging machine with carbon ring further reduced the inertia during winding packaging, improved controllability and extended the service life of the machine. Now they are trying to make it easier to operate and make the film more stretchable
MJ Maillis is very suspicious of the packaging speed claimed by some manufacturers (including the speed of the ring system). Steve Bates said, "to reach the speed of 120 discs per hour, we need to meet various conditions, which is impossible in practice." Indeed, for most industries served by circular winding, including automotive, electronic and electrical, construction, sports and leisure packaging machines, the speed of 100 discs per hour is close to the real level
mark parminter of Inpac estimated the speed of this kind of rotating arm machine, ranging from 40 to 100 discs per hour. The company said that in some cases, the rotating arm technology can catch up with or even exceed the speed of the ring packaging machine. For example, Inpac has developed a two arm rotation system, which enables the packaging speed to reach 120 discs/hour
but even so, most manufacturers admit that there is a certain gap between the speed of the rotating arm system and the ring packaging machine
in terms of cost, the rotating arm system stretching and winding film packaging machine is more dominant
mark parminter of Inpac company compares the octopus ring system stretching and winding film packaging machine with the fully automatic rotating arm system stretching and winding film packaging machine. The price of the former is 50000 pounds, and the price of the latter is 30000 pounds
speaking of the cost of stretch wrapping, Mr. mark parminter estimated that the annual maintenance cost of the top ring system used by some customers would be between 2000 and 3000 pounds. He pointed out that this is very similar to the purchase cost of many low-end machines. Franck mouriaux, general manager of ruag space structure Department of Inpac, added: "This achievement is another result of Altair's close cooperation with ruag space. Its own economy easy is priced at 3000 pounds.
in fact, in terms of cost recovery, Inpac claims that its more expensive machine, economy plus, priced at 5000 pounds, is a better choice. Because this semi-automatic machine adopts strong pre stretching technology, it saves the use of plastic film and can be recycled in less than 12 months Cost. The payback period of similar low-cost equipment is generally three years. Using plus, you can stretch one meter of film to 3.6 meters, which reduces material consumption by 70%
