Technology
We can reproduce gradation and a photograph beautifully by our gravure printing with large lot production and 8-color flexographic printing with small lot production, so as to enable us to make optimal proposals that respond sufficiently to customer demand.
Manufacturing Processes of Laminated Tubes
Horizontal Direction
Laminated web
Plain original materials are always in stock
Single Row Printing
Surface printing in single row in LTP (Laminated Tube Printing) and flexo letterpress
Single-side Cut
Detect by i mark and cut it for each single face
Slit Molding
Round the cutted single-sided sheet and weld the side with a high-frequency hammer
Compression Molding
Extrude resin into mold, insert the mandrel which make cylindrical body into the mold, after compression molded, attached to the shoulder, then cool it
Capping
Rotate the body part fixed to mandrel to attach the cap
Vertical Direction
Seal Cutting Process
Compression Molding
Extrude resin into mold, insert the mandrel which make cylindrical body into the mold, after compression molded, attached to the shoulder, then cool it
Capping
Rotate the body part fixed to mandrel to attach the cap

| Overlapping of the Plate |
△ There is deviation to correspond with color joining |
△ There is variation in precision of colour overprinting |
◎ Possible to perform highly accurate of overprinting and cutter issues |
◎ Possible to perform highly accurate of overprinting and cutter issues |
- fine halftone dots reproduction is possible, superiority in printing of gradation etc.
- Overprinting is possible by flat surface printing
