上田製袋 Product Lineup

Fluororesin films with excellent properties such as extreme low-temperature resistance and chemical resistance can be welded with high quality. The process allows for flexible designs depending on the programming of the laser beam scanning. This welding technology can also be applied to general thermoplastic resins in addition to fluororesins. The combination of laser and resin materials expands the possibilities for realizing new functions. 【Features】 - It enables smooth and high-quality welding without beads or wrinkles, with minimal influence from thermal damage or thermal distortion. - The welding process does not generate toxic gases, dust, or vibrations, allowing for clean and precise welding on delicate workpieces. - Since heat is generated by the absorption of CO2 laser, there is no need to add pigments to the materials. - No jigs or molds are required for each product, making it suitable for small lot production.
