In today's daily life, the development of many industries and the expansion of each field will increase with the progress of society. The increase in population will increase the demand for suction molding, and more and more.
Progress, starting with material innovation.
In recent years, new sterile packaging materials have emerged one after another, which has further promoted the development of sterile packaging. Nano-antimicrobial packaging materials have become a hot topic.
Of course, paper matrix composites are also evident. Paper matrix composites are generally composed of paper, polyethylene, aluminum foil and other materials. Sterile packaging in many Western European countries uses such containers more, especially the aseptic brick boxes and diamond bags produced by the Swedish company Lele Packaging. Typical. It has excellent resistance to oxygen and water vapor, and the printing decoration is also very good. The paper container is sterilized by a combination of hydrogen peroxide and heating-the packaging material is first bathed in hydrogen peroxide and then filled with a tubular heating element at the feeding pipe to achieve high air temperatures. The liquid hydrogen peroxide film on the paper surface is rapidly decomposed into water and new ecological oxygen. Because this oxygen has a strong sterilization ability, it can make the container aseptic.
What would happen if you added a nanometer on top of that? Under the transformation of nanotechnology, pure and natural basic materials can exert amazing bactericidal effects, make bacteria denaturation or precipitation, and once they encounter water, they will exert greater lethality on bacteria.
The finished product made of nanometer antibacterial packaging material has strong adsorption ability, strong permeability, and has strong antibacterial effect after repeated washing. Composite tank is a new type of packaging product that has developed rapidly in recent years. It is made of cardboard, plastic film, aluminum foil in a certain way, and then sealed with metal or plastic cover. The product is good barrier, water-resistant and oil-resistant, can replace the use of metal, glass cans, and reduce product costs, conducive to waste treatment. However, due to the difficulty of killing heat-resistant bacterial spores in composite tanks, it is limited to filling highly acidic juices.
Demand brings a large environment for plastic packaging
The pursuit of plasticization brings new opportunities for sterility.
Sterile packaging of plastic bottles has become popular in developed countries, but its first phase of investment is relatively high, plant hygiene conditions and staff quality requirements are stricter, and it will take time to promote it in the Chinese market.
It is generally believed that aseptically packaged dairy products have the advantages of good taste and high nutritional value compared with secondary sterilized dairy products. Therefore, dairy companies are considering actively launching aseptic packaging. At present, the popular sterile packaging in China is mainly carton packaging, paper pillow packaging and membranous pillow packaging. The sterile barrier system is also known as the original packaging or medical device sterilization packaging system(SBS). Such packaging is required to sterilize it, achieve aseptic operation and clean opening, can provide acceptable microbial barrier properties, can protect the product before and after sterilization, and can maintain the system's internal aseptic environment within a certain period of time after sterilization. Packaging system. For the second and third types of implanted medical devices, such as orthopaedic products, cardiovascular intervention products, surgical implantation devices, etc., hard plastic packaging has almost become a hard demand.
