Packaging technology originated in the 1940 s.
Since 1950, polyester, polyethylene plastic film successfully applied to food packaging, food packages installed quickly, the development of the technology development trend is becoming more and more tend to automated production, how to choose a suitable in many food packages installed a linear combination
of the said packing machine
, Suggestions from the following several aspects to consider.
1, composition, the function of the production line when you need to larger and larger will all the functions are concentrated in a single machine will make the structure is very complicated, also not convenient operation and maintenance, and then food packages installed the function different, matching efficiency of several kinds of combination machine can successfully complete production line, the specific representative models for automatic continuous stretch vacuum packaging machine
2, the related new technology food packages installed on the packing method of a large number of using inflatable packaging instead of vacuum packaging, pneumatic components, packaging materials and inflatable packaging machine
combining three aspects of the study;
On the control technology, more application of computer technology and microelectronic technology;
The application of heat pipe and cold sealing technology in sealing, can also be advanced devices installed directly in the vacuum packaging machine, computer control of coarse grain materials such as mount high-precision combination scale
In rotating or vacuum packaging machine, application of advanced high-speed circular arc surface CAM indexing machinery, concrete on behalf of the machine has automatic vacuum type packing machine.
3, high productivity food packages installed in the production of food packages installed productivity has from several to several ten pieces per minute, thermoforming -
The productivity of sealing machine can reach more than 500 pieces per minute.
4, which has been widely applied automation took a linear combination of the said packing machine, the machine has the process of pumping air into vacuum state, sealing, lettering, cooling one-time completed function, mainly used in meat products, bean products, seafood, agricultural and sideline products such as food packaging.
5, on the single machine multi-function in stand-alone, multi-function, can easily expand the scope of use.
Realize single machine multi-function adopts modular design, food packages installed manufacturer by microcomputer control operation panel, make a vacuum packaging machine is suitable for the different packaging materials, packaging, packaging requirements of different types of vacuum packaging machine, representative models have auto scroll vacuum packaging machine.
Type 6, special customization for different products, food packages installed developed various special customized models of multi-functional, such as soup more sauce, pickled products can choose the concave type vacuum packing machine, for small bag of snack food, can choose four seals vacuum packaging machine, according to need fresh products, you can choose with the function of inflatable air vacuum packaging machine, food packages installed manufacturer at present more popular with the market development, vacuum packed in vacuum and then filling the single gas such as nitrogen, carbon dioxide, oxygen, or two, three kind of a mixture of gases.
The nitrogen is inert gas, filling effect, make the bag to maintain positive pressure, in order to prevent the outside air into the bag, bag of food plays a protective role.
The carbon dioxide can dissolve all kinds of fat or water, leads into the weak acid carbonate, etc have inhibitory the growth of microorganisms.
