Regardless of the current discussion about plastic film, our planet can now be wrapped in plastic multiple times, but packaging film will remain an important part of packaging for the foreseeable future.

However, manufacturers are encouraged to develop thinner and thinner films to save resources, get more out of the same raw material input, and produce more in the same amount of time.

These developments have an impact on machine technology, as larger machines are being used and/or machine speeds are being increased.

In the film manufacturing process, the raw material is usually stretched to its physical limit using rollers and stretchers before tearing.

The rollers used for this process are heated using heat transfer media such as thermal oil or hot water to temporarily increase the entropy within the molecular structure of the plastic. This reduces its stability, and thermoplastic deformability is used for tensile structures.

The DEUBLIN rotary joint is used to transfer the required amount of heat transfer medium to the roll. They act as a link between the fixed feed tube/hose and the rotating roller.

In addition to the large amount of media that flows through the roll every hour, the quality of the finished product needs to be maintained or improved.

This is only possible if the "machine as a whole" operates with extreme precision. Therefore, this also applies to machine components such as rotary joints, because the operating parameters - media, pressure, temperature and speed - always affect the service life.

As a result, there are versions with short and compact designs, single and multi-flow designs, and rotary joints made of stainless steel. All of these products come standard with a reliable and low-wear mechanical seal.

The above describes the advantages of the DEUBLIN rotary joint used in plastic films. In addition, Shenzhen Oudejie Technology specializes in selling new original German imports DEUBLIN rotary joints, and promises to sell products are new original imports, while providing our customers with quotation, selection, product information and other services.
