Aseptic packaging and extended shelf life packaging (ESL) technology (Part 1)

this paper collects some of the latest developments in aseptic packaging and extended shelf life packaging (ESL). At present, the market is full of technical challenges, but the development direction is very clear

glass coating, increase barrier performance

in aseptic packaging and shelf-life extension packaging, the role of barrier coating is very important. This coating can help improve the barrier performance of plastic bottles against oxygen and extend the shelf-life of products. Some people are giving up the research of barrier coating, while others are persistent. Sidel recently announced that the company has processed and sold 1billion ACTIS coated bottles. The type of use depends mainly on the use itself

sig Holdings' efforts in coating have never stopped. The plasma technology jointly developed by the company and Schott hicotec can provide transparent, barrier and 100% recyclable packaging bottles. The company attaches great importance to this technology, and even established sig plasma affairs department, which is responsible for plasma installation and commissioning

the specific name of the technology behind plasma is plasma pulsed chemical vapor deposition (PICVD). Through the joint action of microwave and vacuum, a thin and transparent glass layer is coated on the inner wall of PET bottles. FDA approved the application of plasma in food and beverage packaging in food circular 000329 issued in July 2003. In addition, the European non-profit petcore Organization (PET container recycling Europe) also agreed to the use of plasma technology. The organization is committed to promoting the use and recycling of PET containers and recognized plasma as a fully recyclable packaging container this year

the first plasma prototype was tested in Switzerland. Plasma 12D was officially put into production in July 2003, and the bottle capacity increased from 0 50. Speed up to 10000 bottles/hour. Electronic universal experimental machine is a new generation of double space microcomputer controlled electronic universal experimental machine specially designed for colleges and universities and scientific research institutes. The coated bottles are directly aseptic filled, and then enter the sales channel

Promeet nag, sales and marketing manager of SIG plasma, said that other plasma coating systems were put into commercial production in Japan, and several American companies also expressed strong interest

nag added, "plasma still has a long way to go. Our equipment has been greatly improved since it was put into production, but we will not stop our research and development efforts and will continue to optimize the processing technology and equipment."

Pepsi milk

Quaker milk chillers, a product of Pepsi, was launched in the United States in mid August. According to insiders, Jasper products is responsible for aseptic filling of this 16 Ounce plastic bottle. Jasper products is also the bottler of racing cow. Racing cow chooses a 14 ounce sterile milk beverage, which was launched by Dr pepper/sevenup in March 2003. It adopts the whole-body shrinkage sleeve label, and the impact strength of the shelf life at room temperature for 6 months is used to evaluate the impact resistance of the material or judge the brittleness or toughness of the material. The cartoon cow image on the bottle is very similar to PepsiCo's milk chillers, which withdrew from the market about 1 year ago

milk chillers uses calorie free sweeteners, including sucrose, sucralose, ask, and milk with nutrients close to 2%. "In addition," PepsiCo announced, "because milk chillers adopts the most advanced aseptic technology, the shelf life at room temperature can reach 6 months." Milk chillers' transportation and sales environment are at room temperature, and the retail price is $1.55

light resistant UHT milk

Grupo Leche Pascual in Madrid, Spain, is the first beverage manufacturer to use plastic bottles made of lacpet material (the latest variety in PET). Lacpet is a new material developed by France tergal fibers and Sidel to add titanium dioxide to pet. Titanium dioxide masterbatch is added to PET particles and injected into bottle blanks by injection molding machine. Lacpet bottle is white, so the contents can be protected from ultraviolet radiation

Leche Pascual, a famous European food and beverage manufacturer, has installed two side combi SF ultra 16 FMF 36/36t equipment, which mainly blows 150ml and 1.5L lac "PET bottles, and completes the aseptic filling of UHT milk and lactic acid bacteria drinks. The aluminum foil heat sealing of the bottle mouth is also completed by the combi system in a sterile environment. Downstream of the combi system is the capping machine

"the most common packaging of lactic acid bacteria drinks and UHT milk is paper bricks. Our pet bottle packaging can maintain a 90 day shelf life at room temperature. This packaging form makes our products one step ahead of similar products in the market." A spokesman for Leche Pascual said

although this new packaging can not immediately replace sterile paper bricks in a short time, it has become a new choice

the spokesman also added, "the PET production line is more flexible and the conversion between different tasks is faster, while the paper brick production line can only process a single product and a single size."

some beverage manufacturers are looking for HDPE multi-layer co extruded plastic bottles with black smoke layer with UV barrier function. According to tergal, the advantage of lacpet is that it does not need to adopt multi-layer technology that is very complex in practical application

leche Pascual ordered two side combi at the end of 2004, and the delivery time is the first quarter of 2005. Each system has 16 bottle blowing groups, 36 flow filling valves and 36 sealing devices, and the speed of the system can reach 22500 bottles/hour

the order also includes a microbial confirmation agreement. The agreement will select 10% of the 18000 bottles in each of the three batches for pollution testing

"the test results are very satisfactory." A spokesman for Leche Pascual said, "the first batch of UHT milk was put on the market in early July. The yogurt part is still under testing and is believed to be officially available in the near future."
