Customer Needs
- Reduce total packaging cost — find the optimal thickness and roll-length configuration that meets protection requirements at a per-SKU unit cost aligned with Brazilian market resale margins, without downgrading film performance
- Improve downstream distribution efficiency — standardized packaging dimensions and brand markings allow resellers to identify SKUs quickly during warehousing and shelving, reducing manual sorting errors
- Custom logo-printed cartons and proprietary labels — white-label products struggle to build reseller loyalty in Brazil’s building materials distribution channel; branded packaging is a baseline condition for entry into established distributor warehouses
- Custom film color matched to client brand palette — black or dark-toned PE film creates high contrast on white and cream marble slabs, simultaneously signaling product quality to resellers, differentiating from generic clear film common in the local market
- One-stop sourcing — film production, carton printing, and export packaging handled by a single supplier, eliminating lead time misalignment and quality accountability gaps that arise from coordinating multiple vendors
- Zero product damage throughout — marble countertops are high-value fragile goods; downstream resellers have strict arrival condition standards. Any return caused by film adhesion issues or transit damage directly damages the wholesaler’s standing in their distribution network
Why the Customer Chose Us
Plashield conducted an SKU-by-SKU review of the client’s existing film specifications, reducing over-specified film thickness to the minimum required for each application scenario, and standardizing roll lengths to whole-meter configurations compatible with Brazilian standard pallet dimensions. Unit packaging cost decreased by approximately 12% without requiring any change to downstream customer usage habits.
Plashield delivered full-package branding: logo cartons printed with single-color silkscreen process, color tolerance ΔE ≤ 1.5 for batch-to-batch visual consistency; custom labels with Portuguese-language product description, roll specifications, and SKU codes; film color matched to client brand swatch, providing clear visual contrast on white and cream marble substrates.
The core quality risk in marble protective film is the interaction between the adhesive layer and polished stone — too much tack leaves residue on porous marble surfaces at removal; too little causes edge lifting and detachment during transit vibration. We configured a low-tack adhesive formulation for this client’s polished marble application, running a 24-hour dwell peel test on polished marble substrate before each production batch. No client complaints have been recorded since first cooperation in August 2023.
Brazil’s import customs clearance timelines carry meaningful variability. For each shipment, Plashield provide a complete customs documentation package — commercial invoice, packing list, certificate of origin — with HS code classification verified against actual goods to reduce the probability of triggering Brazilian customs inspection. Production schedule is locked at order confirmation, allowing the client to incorporate arrival timelines into their downstream distribution planning.
Customization covers: film thickness (40–80μm, selected by marble surface type), roll length (standard and custom whole-meter configurations), film width (600–2000mm, covering mainstream marble countertop dimensions), film color (clear, blue, black, and brand-specified colors), and carton structure (single-wall corrugated and double-wall reinforced). All parameters can be independently specified per SKU within a single order — no split ordering required.
Sea freight from China to Brazil spans approximately 35–40 days through tropical high-humidity shipping lanes. Plashield export packaging includes: PE moisture-barrier inner bag sealing each roll (preventing adhesive softening from humidity absorption during transit), double-wall corrugated carton construction for stacking loads during container handling, and pallet configuration verified against container load plan to ensure rolls remain upright and uncrushed throughout the full voyage.
Solutions Provided
- Developed packaging configuration aligned with Brazilian distributor warehousing and shelving standards — carton dimensions compatible with local standard pallets, logo silkscreen printing with ΔE ≤ 1.5 color tolerance, Portuguese-language labels with SKU codes and roll specifications supporting barcode-based distributor inbound receiving.
- Produced custom-color PE film per the client’s brand swatch — primary supply in black, providing high visual contrast on white and cream marble surfaces and differentiating from generic clear film in the local market. Batch-to-batch color consistency maintained within the client’s brand tolerance to ensure visual uniformity across multiple shipments.
- Conducted per-SKU thickness review of the client’s existing specification: polished marble countertop protection configured at 50μm low-tack (balancing protection strength with clean removal); rough-honed and antique-finish marble configured at 60–70μm medium-tack (improved edge adhesion to prevent detachment under transit vibration). Post-optimization unit cost per SKU reduced by approximately 12%; protection performance validated against actual shipment results with no degradation.
- QC protocol for marble substrate covers four checkpoints:
- 24-hour dwell peel test on polished marble surface (180° angle, g/25mm value recorded per batch)
- Zero-residue verification on polished stone after 7-day accelerated aging
- Adhesion uniformity sampling across full roll width
- Carton compression test before shipment (compliant with international export packaging standards).
- QC records included with each shipment, available for the client’s downstream distributor quality documentation.
- The China-to-Brazil sea route spans approximately 35–40 days through high-humidity Indian Ocean and Atlantic shipping lanes. Export packaging uses PE moisture-barrier inner bags sealing individual rolls, double-wall corrugated cartons rated for 4-tier stacking static load, anti-slip pallet stretch film, and a container load plan confirmed before dispatch. Since August 2023, every shipment to this client has arrived with no recorded crush damage or moisture ingress.

Results Achieved
Per-SKU unit packaging cost reduced by approximately 12% following specification optimization, confirmed across actual shipments — the client improved resale margins without adjusting end-customer pricing
Since first cooperation in August 2023, all production batches have passed polished marble substrate peel testing — zero complaints recorded from downstream resellers or end customers across the full supply period
Custom-printed film and logo cartons have established brand recognition across multiple Brazilian building materials market distributor channels — the client reports a measurable improvement in reseller reorder rate since branded packaging was introduced
Continuous repeat orders since August 2023, with annual purchase volume maintained at approximately USD 40,000 — the supply relationship has progressed from trial validation to a stable long-term procurement arrangement
