Krones launches "PET blowing-filling production line"

Krones started to launch the "PET blow-blow-filling integrated production line" for beer (Europe's annual sales have reached 100 million marks, and will reach 2 billion marks in the future). Prior to finding a better blowing process for beer-filled PET bottles, there are currently plasma-based inner and outer coatings, PEN/PET, and multilayer bottle methods, but these methods have advantages and disadvantages.

As a beer packaging container, the first is the issue of safety (bottle bursting), the B-bottle does not allow the bomb to disappear; the second is a lightweight problem, generally 640ml beer bottles are 460 ~ 540g, or to improve the bottle from the perspective of safety The pressure capacity, the bottle weight increased to 600 g; the third is the health issue, the glass is hygienic, the new material needs persuasive certification; the fourth is the appearance of the consumer's senses and fashion issues.

Now, the traditional one-step blowing method is more difficult to guarantee the geometric size of the container, high transportation costs, and there is a secondary pollution problem. The application of nanotechnology in the industrialization of PET beer bottles is best to consider using a two-step method. Will use existing equipment and nanotechnology.

For polyester film manufacturers, it is hoped that nanotechnology will be introduced into the production of polyester film to solve the barrier problem. Enterprises that produce plastic extrusion blow machinery equipment need to solve the problem of combining nano-montmorillonite with PP and PE at the site, then using extrusion blow molding technology to make bottles and improving the barrier properties of packaging bottles.
