G Seal

- A seal without "ears" (the protruding ends of the seal part) is formed using the conventional method. - The conventional ear part is shaped in an R form. - The positioning of the tube is aligned with the actual product, ensuring there is no misalignment. - A direct flame and hot air method is set for the melting of the tube to uniformly melt the seal part (patent obtained). It is also possible to create a buildup at the seal boundary. - Differences in tube diameter can be adjusted, allowing for cost reduction (part-time workers can easily make adjustments).
