Application Scenarios
Product Description
A biaxial stretching film roller is engineered for the high-speed and temperature-sensitive processing stages used in oriented plastic film production. JWELL supplies roller solutions for BOPP, BOPET, BOPA and BOPI biaxial stretching lines, as well as roller types used in lithium battery separator equipment. Available process positions include chill rollers, stretching rollers, preheating rollers, pull rollers, corona rollers, rubber rollers and TEFLON-coated rollers.
Because film-production rollers operate at high rotational speeds, dynamic balancing accuracy is critical to stable line performance. JWELL uses dedicated large-scale dynamic balancing inspection equipment and multiple balancing methods to verify rollers for demanding film applications. This helps support smooth rotation and reliable operation where web stability and consistent processing conditions are required.
Roller-surface temperature variation is another important factor in plastic-film forming. Rollers can use an internal spiral circulation channel to improve heat exchange across the working surface. The design is intended to minimize allowable temperature fluctuation during production, supporting more uniform thermal conditions for film stretching and related processing stages.
For lithium battery separator production, the product range can include stretching, drying and extraction rollers designed to meet the equipment’s precision and stability requirements. Buyers should provide the film type, roller position, face length and diameter, line speed, temperature-control medium, surface treatment, balance requirement and operating conditions. These details allow the roller structure and process configuration to be evaluated for the intended BOPP, BOPET, BOPA, BOPI or separator-film line.
