Product Detailed Description
The Cylindrical Advantage
Flat documents in rectangular boxes crease. Textiles fold into permanent wrinkles. Oddly dimensioned products rattle in excessive void fill. Custom mailer tubes solve format mismatch that rectangular packaging cannot address.
We manufacture spiral wound tubes with controlled crush resistance, end cap engineering that survives handling, and exterior surfaces that carry brand communication rather than shipping labels alone.
Structural Engineering
Spiral Wound Construction
Continuous paperboard strip wound under tension creates tube walls with directional strength. Crush resistance exceeds equivalent thickness folded board. Impact forces distribute around circumference rather than concentrating at corners.
-
Standard wall thickness — 0.125 inch for documents and textiles
-
Heavy duty specification — 0.25 inch for industrial components, hardware, fragile cylindrical items
-
Moisture resistant lining — Wax or polymer barrier for humidity protection during transit
End Cap Systems
Tube failure typically occurs at ends. Our cap engineering options include:
-
Friction fit plug caps — Recessed for flush exterior, plastic or molded pulp material
-
Telescoping overlap caps — Extended tube length with cap sliding over exterior, superior crush resistance
-
Snap ring retention — Metal or plastic rings locking caps against internal pressure
-
Permanent seal options — Adhesive or crimped closure for tamper evidence
Length and Diameter Precision
Custom tooling produces tubes exact to your contents plus minimal clearance. No excessive void requiring filler. No tight fit causing extraction damage. Diameters from 1.5 inch to 12 inch. Lengths to 48 inch without seam.
Surface Finishes
Kraft exterior communicates sustainability and industrial utility. White provides neutral substrate for full color print. Custom options include:
-
Lithographic wrap — Photographic imagery, brand patterns, campaign messaging
-
Spot color printing — Economical brand color matching for volume applications
-
Foil stamping — Metallic accents on kraft or white ground
-
Embossed texture — Tactile patterning for premium positioning
Contents Applications
Documents and Prints
Architectural blueprints, marketing posters, art prints, photographic enlargements. Rigid protection prevents creasing, rolling damage, surface abrasion. Interior diameter maintains flatness without curl memory.
Textiles and Apparel
Scarves, ties, socks, rolled garments. Cylindrical format prevents fold lines, compression creasing. Breathable construction allows moisture equilibrium.
Industrial and Component Shipping
Rods, extrusions, cable assemblies, cylindrical hardware. Heavy wall construction with end cap reinforcement survives freight handling.
Promotional and Gift Items
Wine bottles, specialty food items, rolled certificates, commemorative documents. Premium finishes with ribbon tie points or label windows.
Sustainability Profile
Spiral wound tubes use recycled paperboard content standard. End caps available in molded pulp rather than plastic. Entire construction recyclable as paper in standard municipal streams. Biodegradable in marine or soil environments without persistent microplastic generation.
