Rolled and Glued Body
The vertical joined seam is a normal and necessary part of this manufacturing method.

CLEAR CYLINDERS
Custom clear plastic cylinders with joined seams and separate caps
Clear PET cylinders and PVC cylinders are rolled and glued from sheet. They are not seamless injection-molded containers; top and bottom caps are separate components.
HISTORICAL PRODUCT PHOTOS
Clear cylinders and caps from the former Lung-Lin website
These real examples show rolled clear bodies, visible joined seams and separate top and bottom caps rather than seamless molded jars.
Photos are from the former Lung-Lin website media library and document historical products or applications. Product names and trademarks shown belong to their respective owners. Current diameter, height, sheet thickness, cap fit and printing feasibility require sample confirmation.
CONSTRUCTION & CAP TOOLING
Diameter follows the available round-cap specifications
Confirm inside/outside diameter, cylinder height, sheet thickness, cap fit, printing and packing method before ordering.
Die-Cut Clear Alternatives
For non-round shapes, foldable polygon or square clear boxes use crease lines, tabs and seams.
| Round-cap / mold reference diameters | 55.5, 66.5, 77.5, 88.5, 90, 100, 105, 113, 120, 125, 130, 135, 140, 150, 160, 180 and 202.5 mm |
|---|---|
| Cylinder body height | Up to 350 mm; shorter heights can be evaluated by product and quantity |
| Sheet thickness | 0.20, 0.25, 0.30, 0.35 and 0.40 mm |
| Materials | PET or PVC |
| Opening treatment | Rolled-edge treatment can be evaluated to improve strength and edge feel |
| Cap configuration | Separate top and bottom caps; fit, cap depth and stock must be confirmed when quoting |
The original reference list used 5.55 to 20.25 cm; this is the same as 55.5 to 202.5 mm. These are cap / mold reference labels, not guaranteed finished inside or outside diameters.
PRINTED CYLINDER REFERENCES
Print options with clear glue margins
White ink, spot colors, screen printing and metallic effects can be evaluated. Artwork must leave the vertical overlap seam and the lower gluing/cap-fit area completely unprinted.
AI-assisted print and structure references, not photographs of completed Lung-Lin production. Ink adhesion, registration, glue-margin width, bottom clearance, cap fit and production feasibility require material and sample confirmation.
