Upgrade Strategy

When to Upgrade From Corrugated to SFL Packaging

Evaluate when growing brands should transition from standard corrugated boxes to high-graphics single face lamination.

Upgrade Guide

Standard corrugated packaging is an effective starting choice for growing brands.

Scaling commercial automotive packaging requires targeted engineering: Automotive replacement parts require rigorous corrosion protection, high structural crush resistance for dense cast iron components, and strict barcode readability for automated distribution centers. PM Packaging partners with high-volume brands to ensure G7 color consistency, structural durability, and predictable replenishment.

Rather than treating automotive packaging as generic paperboard, engineering teams must account for product geometry, hanging shelf wear, moisture barriers, and high-speed automated cartoning line tolerances.

Upgrade When Packaging Becomes Part of the Experience

PM Packaging manufactures engineered automotive parts packaging, line-side kits, and retail aftermarket cartons with certified Delta-E color consistency and high-speed box converting. High-speed gang printing and shared dielines reduce per-unit tooling costs while clear technical graphics guide buyers directly to the correct model.

SFL provides microflutes—F-flute (compact retail folding), E-flute (D2C mailers), and B-flute (heavy automotive accessories). SFL prevents folding cartons from bowing under heavy weights, keeping products stable in display slots.

Consolidate Packaging Layers and Simplify Inventory

SFL mailers can often function as both the branded presentation box and the shipping container, eliminating double-boxing. Right-sizing custom SFL dielines reduces excessive void space, cutting down master-case dimensions and parcel freight charges.

Portfolio brands standardize SFL structural platforms to reduce cutting die setups. Reusing standard outer boxes with customizable paperboard inserts helps manage multi-SKU product families under a single replenishment forecast.

Validate SFL Transit Strengths and Total land Sourcing Costs

Converted programs undergo drop and compression testing to verify transit protection for both DTC parcel and retail truckloads. Sourcing reviews map printing, microflute lamination, custom insert assembly, and cross-border logistics under a unified plan.

Landed cost analyses compare SFL unit rates with total component overhead—purchase orders, setups, assembly labor, freight, and obsolete packaging. Transitioning SFL templates alongside product revisions keeps your supply chain agile.

A Controlled Transition

Managing the upgrade includes a phased transition—converting one high-volume family while consuming existing corrugated carton reserves.
