Corrugated Plastic Mailer Box Manufacturer & Supplier
Zhejiang Zhapu Plastic Co., Ltd. is a specialized manufacturer of corrugated plastic mailer boxes, offering a range of foldable, waterproof, and shockproof PP mailers designed for secure e-commerce, logistics, and industrial shipping. Our boxes are produced in-house from virgin polypropylene twin-wall sheet, ensuring consistent quality, durability, and recyclability.
As a Corrugated Plastic Mailer Box manufacturer and supplier, we combine extrusion, die-cutting, and printing capabilities under one roof. This vertical integration allows us to control every step—from raw material to finished box—and deliver custom solutions that meet your dimensional, branding, and performance requirements.
Our Mailer Box Range
We supply several standard mailer configurations, each suited to different shipping and handling conditions. All are foldable for flat storage and quick assembly.
| Product Type | Key Features | Typical Applications |
|---|---|---|
| Tuck Top Mailer Box | Self-locking tuck flap, waterproof, foldable | E-commerce, apparel, documents |
| Airplane Mailer Box | Twin-wall construction, impact-resistant, anti-moisture | Electronics, spare parts, fragile items |
| Shockproof Mailer Box | Enhanced cushioning, waterproof, rigid | Automotive components, medical devices |
Material and Construction
Our mailer boxes are made from polypropylene (PP) corrugated plastic board, also known as twin-wall or hollow board. The fluted core provides high strength-to-weight ratio, while the smooth outer walls accept high-quality printing.
- Thickness: 2.0 mm to 12.0 mm, depending on protection needs.
- Board width: up to 2200 mm, allowing large-format boxes.
- Colors: standard white, black, and custom colors; UV-stabilized options available.
- Additives: anti-static, conductive, flame-retardant grades for specialized applications.
For shipping environments where moisture or impact is a concern, our twin-wall structure offers superior resistance compared to single-wall corrugated cardboard. The material is non-toxic, odorless, and fully recyclable, supporting circular economy goals.
Customization and Branding
We provide complete customization—from dimensions and wall thickness to closure style and printing. Our in-house die-cutting and box-nailing equipment ensures precise folds and consistent dimensions.
- Size: any length, width, and height to fit your product.
- Printing: water-based ink printing (introduced 2024) for eco-friendly, high-resolution graphics.
- Closures: tuck top, airplane (self-lock), adhesive strip, or Velcro.
- Add-ons: die-cut handles, ventilation holes, or custom inserts.
Our engineering team reviews your product dimensions, weight, and shipping method to recommend the optimal board thickness and box style. We provide samples before mass production to verify fit and performance.
Quality Assurance and Compliance
Every production stage—from raw material intake to final packing—is inspected under our ISO 9001 quality management system. Our products have passed SGS testing for safety and performance.
- ISO 9001:2015 Quality Management
- ISO 14001 Environmental Management
- ISO 45001 Occupational Health & Safety
- GRS (Global Recycled Standard) certification
For export orders, we provide test reports and certificates as required by your destination market. Our quality team conducts drop tests, compression tests, and moisture resistance checks on sample boxes to ensure they meet transit conditions.
Production Capacity and Lead Time
Our factory in Pinghu, Zhejiang, operates 9 extrusion lines and supporting die-cutting and printing equipment. With a production team of over 160 people, we handle both large-volume standard orders and smaller custom runs.
Typical lead times are 15-25 days after drawing approval, depending on order quantity and printing complexity. We offer flexible packaging—flat-packed for easy storage and transport—and can arrange sea, air, or express delivery.
