The hottest new technology of plasma coating

The new plasma coating technology

pet bottle is favored by the majority of beverage manufacturers because of its light bottle, not easy to be damaged, can be sealed for storage, completely transparent, compression resistant, does not affect the taste of the filler, recyclable and many other advantages. However, due to the limitations of its barrier performance, many oxygen sensitive and/or carbon dioxide containing beverages, such as beer, milk, red wine and so on, are difficult to use PET bottles for packaging

plasmax 12D, the first plasma coating equipment to improve the barrier performance of PET bottles, jointly developed by sig corplast copperas of Germany and Schott hicotec, has been successfully accepted by bischofszell beverage company of Switzerland

now, PET bottles of bottled beverages coated with plasmax have been placed on the shelves of Migros supermarket in Switzerland, and have been approved by the FDA of the U.S. Food and drug administration

plasmax plasma coating equipment advantages: the internal coating is evenly distributed, the bottle after coating has an excellent barrier layer improvement coefficient, and the coating is glassy, colorless and absolutely transparent. The plasma deposition process is carried out in the inverted state of the bottle to avoid pollution, and the installed process monitoring device can control and ensure the product quality

internal coating enhances protection

since a special adhesive layer is coated at the beginning of the coating, there is good adhesion between the barrier layer and the inner wall of the packaging bottle. Even if the geometry of the packaging bottle is very complex, pulsed plasma can also make SiOx barrier layer effectively and evenly coated on the bottle wall. Therefore, compared with uncoated packaging bottles, this process can achieve a very good barrier layer improvement factor (BIF). Due to the firm adhesion, its advantages can be better reflected when load is applied on the bottle wall and expansion (such as creep) occurs. BIF O2 (oxygen) = BIF CO2 (carbon dioxide) = SiOx barrier layer is glassy, colorless and absolutely transparent. It has been approved by FDA. SiOx coated bottles can be recycled through a variety of recognized recycling technologies. Most processes do not need to add processes. Recycling can be carried out locally in post consumer re crushing (PCR) or completely in post industrial re crushing (PIR)

the PICVD process of Schott (plasma pulse chemical vapor deposition method) can generally be used for internal and external coatings. But it is only used for internal coating at present. Main advantages of internal coating:

◆ the barrier layer will not be damaged

◆ the barrier layer can strengthen the protection of the beverage in the bottle from the influence of oxygen, acetaldehyde and other gases contained in the bottle

◆ because the filled beverage is not in direct contact with the base material of the bottle wall, it can support PCR application

◆ the machine does not need to be cleaned separately, and it is used in combination with sig corplast blomax stretch bottle blowing machine, The coating is carried out in the continuous production high-performance rotary table machine

the deposition process is carried out upside down

in the blumax stretch blow molding process, the plasma deposition process is carried out with the bottle mouth down and the bottle bottom up (bottle upside down), so as to avoid the pollution of the packaging bottle or the pollution of the filled products due to the presence of loose particles

according to the design, the output of the first series of equipment is 10000 bottles per hour. Therefore, in terms of output, it can be directly used in line production in combination with most sterile filling machines. In the process parameter deviation, the extremely strict tolerance requirements are observed, so as to achieve reliable process control and high operation safety. It ensures high-quality and uniform coating, and there is no additional process flow after coating

quality monitoring

the installed process monitoring device can control the equipment to carry out experiments and ensure product quality. The three-level protection principle of high-precision deposition process has been tested in the production of pharmaceutical bottles, and has been further applied and transformed in this new deposition machine

the application of this unique process control system in pet plasma deposition can not only monitor the plasma ignition and whether it meets the process parameters, but also directly and reliably detect whether there is leakage and whether the deviation in the process is too large. For example, if the plasma does not burn or does not meet the process parameters, the opportunity will exclude the packaging bottle. To ensure uniform and high-quality bottle coating

simple and efficient control

due to the configuration of formula memory with multiple retrieval options and the use of intuitive touch screen technology, this model is simple and efficient, easy for the operator to control. The new attachment machine can be combined with three shift production, and the operator can operate normally with only a little training. Moreover, the maintenance of this model is very convenient, which can shorten the maintenance time

greatly reduce costs

after adopting the new sig plasma coating system, the barrier enhanced packaging market is more competitive. The cost of each bottle of packaging is lower than any existing 101 concrete interface treatment agent process. The above cost reduction is mainly due to the low material cost and the reliable mechanical performance of the machine

sig beverage machinery Shanghai Branch was established

or the belt on the piston for testing strength falls off or is too loose, which may cause the piston to not rotate at a uniform speed

sig group is a packaging equipment supplier with business all over the world, which can provide users in the food and beverage industry with a full range of liquid product packaging technology solutions. Its business covers packaging materials, machinery and equipment, production lines, and excellent services are the cornerstone of the brand. Aseptic packaging and traditional packaging technology can be used for the packaging of various containers, such as cartons, PET bottles, glass bottles, etc. In 2002, the sales volume of SIG group reached 1.88 billion euros and the number of employees reached more than 9400

sig group's two main businesses, SIG kangmeibao and SIG beverage machinery, have established their own factories and sales service agencies in China since the mid-1990s, and are currently distributed in Beijing, Shanghai, Suzhou, Guangzhou and other places. The business in China includes the production of packaging materials, the sales of equipment, the provision of convenient technical services and the supply of spare parts for domestic customers

since January 2004, SIG beverage machinery has established its own branch close to sig combo Shanghai office to realize the synergy of SIG group business in the Chinese market. At present, SIG copperas, a professional bottle blowing equipment manufacturer subordinate to sig beverage machinery business, has established a sales and service team in the new Shanghai branch to be closer to customers in East and South China markets and provide more efficient and thoughtful services

sig corplast copperas has more than 28 years of rich experience in design, manufacturing, sales and service in pet processing. Its main products include a two-step bottle blowing machine with a production capacity of 42000 PET bottles per hour
