Product Detailed Description
The Economics of Postal Delivery
Postal services—USPS, Royal Mail, Canada Post, Australia Post, international equivalents—operate with dimensional weight pricing, machinability requirements, and handling automation. Packaging noncompliance triggers surcharges, delays, damage, or rejection. Postage mailer boxes engineer specifically for postal system integration, minimizing cost while maximizing brand presence within regulatory constraints.
We manufacture postage optimized mailers with carrier specification compliance as foundational design parameter.
Dimensional Weight Optimization
Right Sizing
Postal pricing increasingly based on dimensional weight—package volume divided by carrier divisor—rather than actual weight. Excess void space increases cost without value.
Our engineering process:
-
Content dimensional survey
-
Minimal clearance calculation
-
Structural efficiency maximizing interior volume while minimizing exterior dimension
-
Dimensional weight bracket targeting for rate optimization
Standard Postal Sizes
-
Letter size — Maximum 11.5" × 6.125" × 0.25", machinable letter processing rates
-
Flat size — Maximum 15" × 12" × 0.75", flat mail pricing tier
-
Parcel select — Dimensional weight threshold management for ground advantage
-
Priority cubic — Volume based pricing optimization for dense contents
International Postal
-
Universal Postal Union standards — Dimension and weight limits by destination country
-
Customs form integration — Exterior pouch or print area for documentation
-
Clearance efficiency — Smooth surface, readable labeling, machinable construction preventing manual handling delays
Machinability Specifications
Surface Requirements
-
Smooth exterior — Conveyor belt compatibility, no protrusions catching equipment
-
Label adhesion — Proper surface for pressure sensitive address labels, no delamination
-
Barcode scanability — Contrast and reflectivity supporting automated sortation
-
Rigid minimum — Sufficient construction preventing crush in automated handling
Prohibited Features
-
String or wire closures — Catching in equipment, manual handling requirement
-
Clasps or buttons — Dimensional protrusion, machinability interference
-
Irregular shapes — Rolling or jamming in conveyor systems
-
Exterior loose items — Additional handling, processing delay
Material and Construction
Lightweight Corrugated
-
E flute — Minimum thickness for machinability, dimensional efficiency
-
F flute — Microflute option for maximum dimensional control
-
Single wall — Adequate protection for appropriate contents, weight minimization
Folding Carton
-
24pt paperboard — Rigid enough for machinability, lightweight for rate optimization
-
Corrugated pad reinforcement — Selective strengthening without full box weight
Closure Systems
-
Tuck top with friction lock — No tape requirement, machinable profile
-
Peel and seal strip — Adhesive closure, flat profile, resealable for return
-
Self locking die cut — Mechanical closure without added material
Brand Presence Within Constraints
Exterior Print
-
Single color flexographic — Economical, legible, brand recognition
-
Two color — Logo and accent within cost parameter
-
Full color selective — Photographic imagery where margin supports
Interior Surprise
Maximum brand impact where exterior constrained by cost or regulation. Full color interior, messaging, unboxing experience.
Structural Branding
Unique proportion, die cut shape, closure mechanism creating recognition without print cost or regulatory complication.
