Automotive assembly plants depend on having the correct components at the correct workstation at the exact time required.
A line-side package delivers individual components, matched part pairs, or complete assembly kits directly to active production lines. Instead of optimizing only for transport, line-side packaging acts as a physical extension of assembly ergonomics.
At high automotive production volumes, small inefficiencies multiply rapidly into lost labor and assembly delays.
Packages that take extra seconds to open, components packed in wrong orientations, or misidentified similar part numbers disrupt assembly lines. Line-side packaging must deliver parts in repeatable, intuitive configurations.
Engineer standardized paperboard outer cartons, custom inserts, SFL heavy kit boxes, and BOM verification for automotive assembly programs.
SFL Can Support Larger or Heavier Line-Side Kits
Larger automotive assemblies or multi-component kits require substantial structural rigidity to protect heavy metal, electrical, or trim components.
Single-face laminated packaging (SFL) combines a printed paperboard top sheet with a fluted structural layer, delivering superior stacking strength and panel stiffness.
SFL provides:
- Greater structural rigidity for heavy metal bracket and hardware kit loads
- Increased panel strength for line-side rack storage and stacking
- Clear, high-impact printed areas for barcode labels and part numbers
- Seamless integration with paperboard partitions and modular dividers
PM Packaging specializes in SFL, allowing automotive suppliers to use folding cartons for small component kits while upgrading to SFL for heavy assembly kits.

High-Volume Automotive Packaging Programs With PM Packaging
Automotive line-side packaging requires a combination of structural strength, accurate identification, efficient kitting, and dependable replenishment.
PM Packaging works with automotive suppliers and product manufacturers on packaging programs that may include:
- Folding cartons and line-side boxes
- Single-face laminated (SFL) packaging
- Product inserts and dividers
- Multi-component assembly kits
- Multi-SKU packaging programs
- Fulfillment and pack-out support
PM Packaging evaluates part dimensions, kit weights, workstation ergonomics, rack storage constraints, and nearshore replenishment schedules across your automotive lineup.
Treat Line-Side Packaging as Part of the Assembly Process
Automotive packaging does not stop when a truck arrives—it continues working directly beside the assembly workstation.
Standardize paperboard cartons and SFL kit boxes across part families, use modular inserts for part orientation, and enforce BOM verification to ensure flawless line-side execution.
Support high production quantities without multiplying labor, handling, and inventory complexity.
Contact PM Packaging to discuss your automotive component program, annual quantities, part-number count, kit configurations, component weights, line-side requirements, SFL opportunities, inserts, pack-out process, and replenishment needs. PM Packaging can help develop high-volume line-side packaging programs designed around repeatable production and efficient automotive assembly.
