Precision-manufactured with optical-grade TPU, dual-lock sealing latches, and high-frequency welded seams. Built for extreme outdoor performance.
As a specialized OEM/ODM factory and global exporter of waterproof outdoor phone bags, mobile pouches, and rugged outdoor accessories, our manufacturing philosophy is anchored in advanced polymer science, structural integrity, and zero-defect quality control. Outdoor smartphone protection has evolved beyond simple splash protection; modern consumers, outdoor professionals, marine navigators, and tactical operators demand total immersion protection without sacrificing device functionality.
Information Gain Insight: Standard PVC pouches suffer from plasticizer migration, yellowing under UV exposure, and structural embrittlement at sub-zero temperatures. LEVORE's OEM production lines utilize 100% pure Thermoplastic Polyurethane (TPU) engineered with ether-based molecular backbones, achieving 300% tensile elongation and total cold-crack resistance down to -30°C.
Conventional stitch-and-tape methods fail under continuous hydrostatic pressure because needle punctures create stress concentration points. Our facility utilizes state-of-the-art High-Frequency (RF) Voltage Welding machines operating at 27.12 MHz. By subjecting TPU sheets to localized electromagnetic energy under pneumatic pressure, the polymer chains fuse at the molecular level, creating a monolithic seal that exceeds the tensile strength of the raw material itself.
Water intrusion occurs most frequently at closure interfaces. Our proprietary ABS/PC injection-molded locking bars utilize a dual-stage cam mechanism with internal silicone gaskets. Furthermore, to overcome the acoustic dampening inherent in heavy-duty waterproof enclosures, our OEM solutions incorporate micro-porous expanded PTFE (ePTFE) acoustic membranes. These allow sound waves (audio calls and music playback) to pass through cleanly while blocking water molecules under high surface tension.
Certified IPX8 standard withstands 30 meters (100 feet) continuous water pressure for over 2 hours without humidity seepage.
Ultra-thin 0.2mm optical TPU film maintains screen touch responsiveness, facial recognition unlocking, and camera clarity.
Integrated perimeter air chambers prevent heavy smartphones (up to 350g) from sinking in lakes, rivers, or oceans.
When selecting an OEM/ODM supplier for international distribution, understanding material longevity and environmental compliance is crucial. Below is an engineering comparison matrix evaluated under laboratory conditions.
| Performance Metric | LEVORE Industrial Ether-TPU Bag | Standard Market Commercial PVC Bag | OEM Buyer Advantage |
|---|---|---|---|
| Waterproof Rating | IPX8 Certified (30 Meters Depth / 2 Hours) | IPX7 / Basic Splash Proof (1 Meter Depth) | Zero return rates due to immersion failure |
| Tensile Strength & Tear Resistance | > 45 MPa (High Tear Resistance) | 15–20 MPa (Prone to tearing at corners) | Withstands rugged outdoor & tactical abuse |
| Low Temperature Flexibility | Remains fully flexible at -30°C | Becomes brittle and cracks below 0°C | Suitable for winter sports & alpine environments |
| Optical Transparency (Camera Window) | 99.2% Light Transmission (Optical Grade) | 85–90% Transmission (Causes blur/haze) | Enables 4K underwater video recording |
| Environmental Compliance | REACH, RoHS, BPA-Free, Phthalate-Free | Contains toxic plasticizers (DEHP/DINP) | Seamless import access into EU, US & JP markets |
| UV Degradation Resistance | Grade 4.5+ Anti-Yellowing (1000h UV Test) | Turns yellow and sticky within 30 days | Extended shelf life & premium brand perception |
The global market for outdoor mobile accessories is undergoing a rapid transition driven by changing consumer behaviors, technological integration, and stringent regulatory policies across major B2B sales channels.
Modern consumers no longer accept single-purpose phone dry pouches. Leading distributors are requesting ODM designs that integrate internal magnetic rings compatible with MagSafe wireless chargers and magnetic mounts. Simultaneously, seamless pairing with outdoor Bluetooth headsets, over-ear noise-cancelling earmuffs, and bone-conduction audio gear requires pouches to maintain zero electromagnetic signal shielding while preserving waterproof seals.
Environmental legislation in the European Union (such as the EU Green Deal and ESG reporting mandates) is driving retail buyers toward sustainable sourcing. Future-ready factories must offer post-consumer recycled TPU (rTPU) formulations that maintain strict IPX8 physical performance without compromising crystal-clear camera windows.
With the surge in popularity of stand-up paddleboarding (SUP), kayaking, offshore sailing, and scuba diving, the addressable market for heavy-duty submersible dry bags has expanded beyond niche outdoor retailers into mass consumer electronics channels, airline duty-free shops, and lifestyle brands.
Established over a decade ago with design heritage rooted in Rome, Italy, LEVORE operates state-of-the-art OEM/ODM production facilities supplying B2B clients in over 30 countries. Our integrated ecosystem combines precise injection molding, high-frequency voltage welding, automated assembly, and strict quality assurance protocols.
We provide full-service ODM customization—from rapid 3D prototyping and custom Pantone color matching to private-label silk-screen printing, retail packaging design, and DDP international logistics management.
Clear, direct answers regarding custom manufacturing, minimum order quantities (MOQs), quality certification, and logistics.
For standard TPU outdoor phone bags with existing mold specifications and custom logo printing, physical samples are completed within 3 to 5 working days. For custom ODM projects requiring original CAD design, 3D prototype modeling, and custom sealing latch molds, sample delivery takes 12 to 18 working days depending on structural complexity.
We employ a 100% two-stage testing protocol. First, every batch undergoes pneumatic pressure testing prior to final assembly. Second, representative samples from each production run are submerged in automated hydrostatic testing chambers at 3.0 BAR pressure (equivalent to 30 meters depth) for 60 minutes. Certificates of Conformance (CoC) and laboratory test reports are provided with each shipment.
Our standard MOQ for logo silk-screen printing on existing stock colorways is 500 units. For custom Pantone color matching of TPU films, custom lanyard webbing, or specialized retail blister card packaging, the baseline MOQ is 1,000 to 2,000 units. We also support flexible low-MOQ trial orders for established global brand partners.
Yes. Our bags utilize 0.2mm high-transparency optical TPU film with dielectric properties that ensure capacitive touchscreen responsiveness. Face ID optical sensors function seamlessly through the crystal-clear lens window, maintaining less than 0.8% light distortion for high-definition underwater photo and video capture.
Absolutely. All raw materials (TPU sheets, ABS locking clips, silicone seals, nylon lanyards) undergo independent SGS/TÜV testing to guarantee full compliance with EU REACH (SVHC list), RoHS 3.0, US California Proposition 65 (Phthalates & Lead-free), and BPA-free safety benchmarks.
Our engineering team provides comprehensive ODM assistance, including integrated perimeter air-cushion floatation walls, internal card/cash dividers, dual-sided transparent camera windows, integrated audio headphone jacks, MagSafe magnetic ring alignment, and heavy-duty tactical carabiner attachment loops.
Standard mass production lead time for orders between 5,000 and 20,000 units is 18 to 22 calendar days following final sample approval and deposit receipt. Our automated RF welding machines and high-speed cutting tables ensure continuous daily production capacity of over 15,000 units.
We support EXW, FOB (Shenzhen/Ningbo/Hong Kong), CIF, CFR, and full DDP (Delivered Duty Paid) door-to-door delivery by air express, sea freight, or rail cargo. Our logistics department handles customs clearance, import documentation, and Amazon FBA warehouse prep labeling directly.
