Stretch casing tray packaging technology overseas application case

Coca-Cola Company

Higher operating speed, lower number of membrane feeds

To further increase product output, reduce costs, and improve the stability of product packaging. The Danish company Tapperierne Coca-Cola recently made an important investment in its factory in Fredericia, Denmark. An important part of this investment was Coca-Cola's ordering of a highly efficient stretch casing film packaging machine to Rachmeier Packaging Machinery in Denmark. Coca-Cola's 1.5-litre PET bottled cola is usually packed in 3 or 4 bottles together; 0.5 litre PET bottled cola is usually 6 bottles packed together. In order to facilitate transportation, a fully automated packaging system is required to be able to pack 120 metric tons per hour of output and operate 51 hours a year, 5 days a week, and 16 hours per day. By using a stretch-wrapping film packaging machine produced by Lachmeer, Coca-Cola not only increased the production of the product, but also reduced the number of frequent film feedings due to the use of conventional winding-wrapping machines, and the most important point was that The overall stability of the stack. The stretch casing film packaging machine produced by Rachmeyer can pack stacked pallets. The machine automatically measures the pallet height before the pallets enter the machine. Depending on the size of the different trays (eg quarter tray, half tray to full tray size) the same machine can choose different film sizes for packaging. The film cover is automatically formed on the top of the machine and covers the entire stack until the bottom of the tray. In addition, the stretch-sleeve film packaging prevents dust from invading; due to the use of a transparent film, Coca-Cola can more easily track the product; at the same time, it improves the stability of the stack. Stretch casing film packaging overcomes all the problems that may occur with traditional winding packages. Workshop manager Peter Hoeeg Jensen said: “Since our industry has a very high weight requirement for the machine, I always doubt the engineering quality of the new equipment. But the packaging machine produced by Rachmeier proves to us that it has The extremely high quality, robust and stable system, and simple operation make it a completely reliable device. Moreover, Rahmeyer is a very good partner and it always listens to our needs and responds promptly.”

New Stretch Sleeve Packaging Effectively Addresses Problems with Automated Inbound System

Interbrew, an internationally renowned brewing company, invested in its new Leuven subsidiary in Belgium and purchased a new back-end packaging production facility, which solved the problems caused by the automated storage system and saved money. The Leuven branch supplies bottled and canned beer for the Belgian and European markets. The Interbrew Group has invested in the purchase of Lachmer's stretching sleeves. So far, it has been used very well.
Previously, the Leuven branch already used shrink sleeve equipment. Nico Van Tilt of Interbrew Technical Department said: At that time, the main purpose of purchasing this set of stretching sleeve equipment was to solve the problems caused by the company's original automated storage system. They mainly want to use stretching sleeve equipment to make up for the problems caused by ordinary wrapping equipment, for example, due to the loose or loose end of the wrapping, causing the problem that the product cannot be put on the shelf properly.
In order to find a new packaging solution, Nico Van Tilt, an engineer at the Leuven branch, and Peter Sauer, the packaging department, contacted Rachmer's ITRA company in Belgium. Rachmer introduced the new principle of the stretch-sleeve machine and took them to visit a machine being used by Faxe in Denmark. After the visit of the engineer Van Tilt, he said: “A device with such a high technical requirement requires only minimal maintenance.” After using Rachmeier's test equipment, the coded goods were carried out several times. After the trial, Interbrew Group saw that Rachmeier's stretching casing system was more stable than the ordinary shrink casing system during loading and unloading.
Interbrew has improved the quality of its packaging after opting to use Rachmeier's stretching sleeve system instead of the normal shrink wrap system. Engineer Van Tilt added: "After using this new stretch-pulling system, our customers can get better-quality packaging with higher shelf-display quality."
According to Mr. Sauer, the primary reason for choosing a stretching sleeve system instead of an ordinary shrink sleeve system is that the use of a stretching sleeve system can avoid the looseness of the wrap-around seal ends and cause problems during the automatic loading process. Interbrew also has a stretch wrapper, but it has had a lot of problems with automatic putting. Since the shrink sleeve is fixed at the bottom of the entire crucible, when transporting the shrink-wrapped crucible from the packaging line with a forklift, the front end of the forklift must be pierced by the packaging film, thus eliminating the use of a shrink wrap as a new package. method. At the same time, Interbrew also recognized that another major advantage of stretch-sleeve equipment is that the use of stretch-sleeve-packed goods can isolate bad weather and improve the display of goods.
Mr. Allan Thysen, Chief Sales Manager of Rachmer Company, stated: “Our tensile sleeve device can handle films with a thickness of 40 microns. At this point we can see that it is thinner than ordinary shrink wrap equipment in the film. The advantages of consumption.” In addition, Mr. Thysen also believes that when using shrink sleeve packaging equipment, the packaging film used for each shipment is fixed. However, when using conventional shrink wrap equipment, the operator may choose to use a multilayer film for security reasons, thereby increasing the cost of wrapping each shipment.
The stretch-cannula equipment installed at Interbrew's Leuven branch can handle bottled beer pods measuring 1200 mm x 1000 mm at speeds up to 60 mph. Moreover, Lahmer's tensile casing equipment has great potential. The maximum operating speed of a single device can reach 150 mph.
The stretch-sleeve equipment can operate on automatically palletized goods, and this fully-automated equipment can automatically measure the size of each shipment before the goods enter the machine, and if it deviates from a preset production line The device can be automatically detected. The device can process wrapping film of a suitable size and then apply the film to every shipment without any heating process. This will ensure the proper amount of film, reduce losses, and reduce material costs.
Nico Van Tilt said that the performance of the rear-end production line is crucial. So, another reason to choose Rachmer's stretch casing equipment is that Interbrew has established close relationships with engineers from Rachmer and ITRA throughout the project, both from the start-up phase and now.
