PP Corrugated Briefcase — Waterproof, Crush-Proof Document Protection
A leather briefcase costs $300 and gets ruined in the rain. A metal document case weighs 5 kg before you even put papers in it. A nylon bag offers zero crush protection for architectural drawings and legal files.
PPBOXY’s PP Corrugated Briefcase is the answer to all three problems in a single product. Constructed from high-impact Papan berongga PP — the same twin-wall polypropylene used in industrial protective packaging — this briefcase delivers:
- 100% waterproof protection — rain, spills, and wet surfaces pass right off
- Crush-proof twin-wall structure — protects contents from stacking weight and impact
- Under 1.5 kg empty — less than 1/3 the weight of a metal document case
- Full custom branding — your logo, colors, and design on every case
- Recyclable PP — supports corporate sustainability commitments
Unlike leather, it doesn’t stain. Unlike metal, it doesn’t dent. Unlike nylon, it doesn’t let your documents get crushed when someone stacks a box on top.

Industry & Professional Applications
Legal Professionals: Court documents, case files, and evidence folders stay dry and uncrushed — rain or shine, courthouse to car. Custom printing with firm logo projects a unified professional image.
Architects & Engineers: Rolled and flat drawings survive site visits intact. Unlike cardboard tubes that crush and leather folios that stain, a PP corrugated briefcase handles construction site conditions without compromising contents. The lightweight design means carrying plans across a job site all day doesn’t become a workout.
Sales Teams & Field Representatives: Equip your entire sales force with matching branded briefcases. Custom color-matched to corporate identity, with logo prominently displayed. They project consistency at every client meeting. When empty, they fold flat for easy storage — deploy for client visits, store between trips.
Corporate Gifts & Promotional Products: A practical, branded item that recipients actually use — not another pen or mug destined for a drawer. Customize with company logo, event branding, or employee name. Ideal for: new hire welcome kits, client appreciation gifts, conference giveaways, dealer/distributor incentive programs.
Training & Education: Training materials, participant handbooks, and certificates arrive organized and protected. Custom-printed with program branding — creates a premium learning experience from the moment participants receive their materials.
For other document and component organization needs, explore our polypropylene corrugated board dividers and custom plastic shipping containers for larger-scale transport.
Custom Branding — Your Logo on Every Case
This is where the PP corrugated briefcase truly outperforms traditional briefcases. Unlike leather embossing (expensive, limited area) or metal engraving (barely visible), PPBOXY’s PP corrugated sheets accept full-color screen printing across the entire case surface:
- Full-bleed logo printing — your brand covers the entire front, back, or both
- 1-4 color screen printing — crisp, durable, professional finish
- Corporate color matching — exact Pantone matching for brand consistency
- Variable data — individual names, department codes, or sequential numbering
- QR codes — link to digital catalogs, training videos, or contact information
The same printing technology we use for outdoor corflute signs — engineered for years of weather exposure — is applied to your briefcases. The print won’t fade, peel, or scratch off under normal professional use.

Soalan Lazim
Q1: Is the PP corrugated briefcase really waterproof?
Yes. PP (polypropylene) is naturally 100% waterproof with zero moisture absorption. The briefcase can be used in rain, placed on wet surfaces, and wiped clean without any water penetration. It provides IPX4-level splash protection for documents inside.
Q2: How much weight can the briefcase hold?
The load capacity depends on the briefcase size, sheet thickness, and structural design. Made from durable twin-wall corrugated polypropylene, PPBOXY briefcases provide excellent rigidity and compression resistance for carrying documents, catalogs, samples, and promotional materials. For heavier contents, we can customize the material thickness and reinforcement structure to meet your specific requirements.
Q3: What sizes are available?
We manufacture to your specifications. Standard sizes accommodate A4/letter documents and legal-size files. Custom sizes are available — provide your document dimensions and we’ll design the optimal case.
Q4: Can the briefcase be printed with our company logo?
Yes. We offer 1-4 color screen printing for logos, company names, and branding. Full-bleed printing across the entire case surface is available. The print is durable and won’t fade or peel under normal professional use. See the Custom Branding section above for details.
Q5: What is the minimum order quantity (MOQ) for branded briefcases?
We don’t tie you down with a minimum order requirement. Whatever your volume — a few pieces for testing or a massive bulk order — we’re equipped to handle it with ease.
Q6: How does the closure system work?
The briefcase features high-impact PP clasps that snap securely closed. The clasps are molded from the same polypropylene material as the case, ensuring they won’t rust or corrode. They provide secure closure while allowing quick one-hand operation.
Q7: Is the PP corrugated briefcase suitable for air travel?
Yes. The lightweight construction makes it ideal for carry-on use — it won’t contribute significantly to weight limits. The crush-proof structure protects documents from overhead bin pressure. Dimensions can be customized to meet specific airline carry-on requirements.
Q8: How does it compare to a leather briefcase in appearance?
A PP corrugated briefcase has a clean, modern, technical appearance — it won’t be mistaken for leather. The value proposition is different: it’s waterproof (leather isn’t), crush-proof (leather isn’t), fully printable (leather can only be embossed), and costs a fraction of the price. For field professionals, branded team deployment, and corporate gifting, these functional advantages outweigh the material aesthetic difference.
Q9: Can I order samples before bulk production?
Yes. We produce evaluation samples within 3-5 business days. For custom-printed samples, we’ll produce one unit with your artwork for approval before proceeding to full production.
Q10: Are PP corrugated briefcases recyclable?
Yes. The entire briefcase is 100% polypropylene (resin code 5) and can be processed through standard PP recycling streams. At end of life, it doesn’t need to be disassembled — the clasps, body, and handle are all the same material.
