Many commercial packaging programs are built around two boxes: a printed retail folding carton and an outer corrugated shipper added solely to survive transportation.
Single Face Lamination (SFL) packaging combines the crisp aesthetic presentation of a 7-color litho-printed top sheet with the structural rigidity of microcorrugated fluting, allowing brands to engineer a single package capable of serving both retail display and parcel distribution.
Eliminate double-box packaging expenses, redundant pack-out labor, and excessive dimensional freight weight.
Rather than wrapping a lightweight folding carton in another brown corrugated box and void fill, an engineered SFL structure consolidates product protection, internal retention, and branded unboxing into one streamlined package with PM Packaging.

Why Are You Using a Secondary Shipping Carton in the First Place?
Secondary shipping cartons often accumulate over time as brands add ecommerce or expand into club stores without revisiting their foundational packaging architecture:
- Compression and pallet stacking strength
- Drop, shock, and puncture resistance
- Corner and edge impact protection
- Scuff prevention for retail gloss coatings
- Space for carrier labels and barcodes
- Internal vibration dampening
SFL merges a smooth offset-printed paperboard top sheet with fluted corrugate (N, F, E, or B flute), providing structural strength without sacrificing high-resolution graphics.

Key Engineering Factors for SFL Consolidation
Successfully eliminating the outer carton requires engineering the package around six key performance requirements:
1. Upgrading Weak Folding Cartons
Products that bow panels, crush corners, or flex bottom seams on paperboard can upgrade to microcorrugate (E-flute / F-flute) for superior vertical compression while retaining photo-quality offset print.
2. Scuff-Resistant Protective Coatings
Protective aqueous coatings, soft-touch laminates, and specialized scuff-resistant varnishes ensure that high-resolution brand artwork survives conveyor sorting, parcel handling, and transit friction.
3. Integrated Internal Retention Inserts
Die-cut paperboard trays, cradles, and roll-over partitions lock the product in place, eliminating internal movement and preventing heavy components from impacting outer box walls.
4. Strategic Flute Profile Selection
Matching flute profiles to product weight: F-flute for sleek retail folding characteristics, E-flute for balanced rigidity and cushioning, and B-flute for heavy hardware, kits, and club-store packaging.
Total Landed Cost Comparison
| Cost Parameter | Conventional Two-Box System | Consolidated SFL System |
|---|---|---|
