SIEL

What SIEL does

Groupe SIEL (legal entity SARL SOCIETE INDUSTRIEL D EMBALLAGE ET DE LOGISTIQUE) is a privately held, family-owned French SME founded in 2006 in Saméon, Nord de la France. It designs and manufactures custom industrial packaging—primarily wooden crates, cradles, pallets, and specialized protective housings—for the export of heavy, oversized, and high-value equipment across maritime, road, rail, and air transport. The company positions itself as a specialist in Category 4/C (hermetic with dehydration barrier) and Category 4/B (water-resistant) crates, NIMP15/ISPM15 heat-treated wood for international phytosanitary compliance, VCI corrosion-inhibitor protection, and custom solutions including dangerous-goods packaging. Its vertical customer base spans industrial manufacturing, aerospace & defense, maritime/logistics, and dangerous goods, with named segment pain points centered on shock/vibration protection, corrosion, moisture, UV, and regulatory compliance during export.

The technical stack is centered on a 5,000 m² covered workshop equipped with two 5-tonne overhead lifting bridges and forklifts, enabling handling of loads from a few kilograms to over 50 tonnes. Core processes include thermosolderable sheathing, VCI film and cover treatment, hermetic sealing with desiccant sachets, custom calage and arrimage (lashing/wedging) inside 20ft, 40ft, open-top, flat-rack, and high-cube containers, and industrial marking. SIEL is certified under SEI member n°138 / SEILA approval, FSC sustainable forestry, and IPPC ISPM15 (certificate NC12065), and adheres to IATA and ADR transport standards. Engineering is project-driven via an in-house study bureau that analyzes each item to determine optimal crate category, dimensions, transport mode, and protective configuration.

Commercially, SIEL operates a direct B2B sales motion with no intermediaries: clients request quotes through the website or by phone, and pricing is quotation-based and exclusive of tax, tailored to dimensions, weight, packaging category (e.g., 4/B, 4/C, 2/B), and transport mode. Revenue streams are project-driven (industrial packaging execution), supplemented by ready-to-use packaging materials supply, container-loading (empotage) as a service, and short- or long-term storage with 24/7 accessibility. Marketing relies on the company website (blog with technical articles and case studies), a quote-request funnel, and a LinkedIn company page; no paid acquisition channels are identified. The company has no disclosed institutional investors, parent, or subsidiary structure and is bootstrapped under family ownership.

Direct peers

• Tri-Wall: Tri-Wall is a global heavy-duty packaging specialist producing triple-wall corrugated and wooden packaging for industrial and export applications. It competes directly with SIEL in custom-engineered crates for oversized, high-value industrial equipment across aerospace, automotive, and heavy manufacturing segments.
• GWP Group: GWP Group is a UK-based protective packaging manufacturer offering custom wooden cases, crates, and export packaging for industrial equipment. It targets the same B2B export logistics customers as SIEL with comparable engineered wood packaging solutions.
• Nefab: Nefab is a Sweden-founded global industrial packaging company specializing in engineered packaging including wooden crates, foams, and complete export packaging solutions for heavy equipment customers in similar verticals (aerospace, defense, industrial machinery). It is the closest scaled direct competitor to SIEL's core offering of custom wooden industrial packaging.
• Boxon: Boxon is a Sweden-based industrial packaging company offering custom wooden crates, pallets, and protective packaging along with packaging machinery and automation services. Its wooden packaging product lines directly mirror SIEL's custom crates and pallets for export logistics.

Broad incumbents

• DS Smith: DS Smith is a major European packaging manufacturer specializing in corrugated and sustainable packaging solutions for industrial and consumer customers. Its industrial division offers export packaging that competes with SIEL's commodity wooden crate and pallet lines as part of a much larger portfolio.
• Mondi: Mondi is a global packaging and paper group with significant operations in corrugated packaging, wooden pallets, and industrial packaging solutions. Its wide product portfolio serves similar heavy-industrial and export customers as SIEL, but at much greater scale and across many geographies.
• Sonoco Products: Sonoco is a global diversified packaging manufacturer serving industrial, consumer, and healthcare end markets with products ranging from protective packaging to reels and wooden industrial components. It competes with SIEL in the broader industrial protective packaging category though not as a focused specialist.
• Smurfit Kappa: Smurfit Kappa is one of Europe's largest paper-based and industrial packaging manufacturers with operations spanning corrugated, wood-based, and protective packaging. While not specializing in custom heavy wooden crates to the same degree as SIEL, its broad portfolio overlaps in industrial export packaging for European manufacturers.
• Sealed Air: Sealed Air is a global protective and food packaging company offering a broad range of packaging materials including foams, films, and protective systems used in industrial shipping. It overlaps with SIEL's VCI and protective films/cover offerings as part of a much wider industrial portfolio.

Regional players

• Raja Group (Rajapack): Raja Group is a France-based packaging distributor selling packaging materials, crates, and protective products to European B2B customers. While not a direct custom-manufacturing peer, it competes with SIEL in the ready-to-use packaging materials supply stream within France and neighboring markets.
