Application of Suzhou Jwell High-speed Rubber-coated Rollers in Biaxial Stretching Film Equipment

Biaxially stretching film is a high-performance polymer material obtained through precise physical processing. The core process involves subjecting a thick sheet of molten polymer to forced stretching, first in the longitudinal direction and then in the transverse direction, under precise temperature control,Which makes the originally disordered molecules highly ordered on a two-dimensional plane, and then "lock" this structure through cooling and heat setting processes. Similar to the process of making Lamian Noodles, the ordered arrangement of molecules enhances toughness and transparency.This microstructural reorganization endows the film with superior properties that surpass those of conventional cast films.Specifically, biaxial stretching film significantly enhances tensile strength, elastic modulus, and tear resistance in terms of mechanics.It offers higher transparency and gloss in optical applications.The barrier properties of the film are significantly enhanced due to its dense molecular arrangement, resulting in excellent waterproof and moisture-proof properties.Additionally, it features uniform thickness, dimensional stability, and low thermal shrinkage. Its surface treatment makes it ideal for further processing such as corona treatment, coating, or metallization.These characteristics make it widely used in high-end packaging, electronic materials, and other fields, achieving a leap from basic polymers to high-performance functional substrates.

Suzhou Jwell rubber-coated rollers are among the equipment components that significantly impact product performance in the production of biaxially oriented film.It directly affects the flatness, thickness uniformity, surface quality, and production efficiency of the film.During the production process, rubber-coated rollers serve as “flexible guardians,” which directly impacting film quality.Meanwhile,It effectively improves edge quality through elastic clamping, preventing edge curling, warping, or damage caused by rigid contact, ensuring high-speed and stable winding.Its smooth traction maintains stable tension in critical areas of the film, preventing unexpected stretching or compression, thereby ensuring uniform thickness across the entire sheet.In addition, the flexibility of the rubber surface significantly reduces the risk of the film being torn during high-speed roller passing, enhancing production continuity.

Finally, the wear resistance of high-quality roller surfaces ensures the stability of equipment operation and product quality, providing strong support for reducing usage costs and improving yield rates.

Performance of Suzhou Jwell Rubber-Coated Rollers. In the high-temperature, high-speed, and high-friction environment of biaxial stretching film production, rubber-coated roller materials must possess comprehensive and integrated performance.It needs to withstand high temperatures for a long time without softening or deforming, and has extremely high wear resistance to withstand continuous cutting at the edge of the filmThe material must possess both excellent tear resistance and chemical resistance to withstand mechanical impact and resist the erosion from oils and precipitates.During high-speed operation, the roll body must maintain dimensional stability and dynamic balance to prevent vibration from affecting film quality.In addition, precise control of the friction coefficient can be achieved by adjusting the rubber formula to meet the process requirements of different film materials, ensuring stable clamping and smooth traction.

Summary: Biaxially oriented film undergoes a molecular restructuring process through biaxial stretching, resulting in significantly superior mechanical strength, optical clarity, barrier properties, and dimensional stability compared to conventional cast film.During production, Suzhou Jwell rubber-coated rollers ensure film edges remain flat, thickness is uniform, prevent tearing, and maintain surface cleanliness through flexible clamping and traction.This roller must possess high-temperature resistance, wear resistance, tear resistance, and excellent dynamic balance to withstand high-speed production environments. It is a critical component for ensuring film quality and production efficiency.
