Bend Outward: The ends of the paper tube are bent outward, creating a flared edge. This process enhances the aesthetics and durability of the tube.

Bend Inward: The ends of the paper tube are bent inward, creating a folded edge. This process improves the sealing and structural stability of the tube.

Gold Stamping: Similar to hot silver, but with gold foil, creating gold patterns or text on the paper tube surface, adding a luxurious touch to the packaging.

UV Printing: Uses UV-curable ink for printing, offering advantages like fast drying, waterproofing, and wear resistance, with bright colors and glossy effects.

Concave-Convex: This technique creates a three-dimensional effect on the surface of the paper tube by pressing, adding texture and visual depth.

Gold Printing: A special technique that gives the paper tube surface a shimmering gold laser effect, typically used for high-end product packaging.

Matte Coating: A matte finish is applied to the surface of the paper tube, reducing gloss and enhancing the texture and premium appearance.

Covered with Light Film: A transparent glossy film is applied to the surface of the paper tube, increasing gloss, wear resistance, and water resistance.

Embossing Process: Mechanical pressure is used to imprint specific patterns or textures on the surface of the paper tube, enhancing its decorative appeal and tactile feel.
