When One Carton Fails, Thousands of Dollars Are at Risk
In solar PV module export, packaging is not a minor detail.
Each carton may contain:
- High-efficiency solar panels
- Tempered glass surfaces
- Aluminum frames
- Precision junction boxes
Average weight: 25–35kg
Transit duration: 30–50 days
Environment: humid sea containers, stacked pallets, global transshipment
If carton sealing fails:
- Panels shift and crack
- Moisture penetrates packaging
- Edge compression causes carton rupture
- Insurance claims increase
In PV export, packaging integrity equals shipment safety.
The Hidden Risk in PV Module Logistics
Solar modules are usually shipped in:
- Large corrugated cartons
- Palletized stacks
- Stretch-wrapped and container-loaded
During sea transport:
- Temperature fluctuates significantly
- Condensation forms inside containers
- Pallets experience compression stress
- Long stacking periods increase pressure
Low-grade OPP tape may:
- Lose adhesion under moisture
- Experience edge lifting
- Tear under compression
- Soften in high temperature
For exporters shipping 100+ containers annually, even a 0.5% damage rate can erase profit margins.
Why TONGXIE OPP Tape Is Ideal for Solar Panel Export
1️⃣ High-Tensile BOPP Film for Heavy Compression
PV cartons are heavy and tightly stacked.
TONGXIE provides:
- 50–72 micron film thickness
- High tensile strength
- Low elongation under stress
- Strong puncture resistance
This ensures the tape remains intact under pallet stacking pressure.
2️⃣ Moisture-Resistant Acrylic Adhesive for Sea Freight
Sea containers create humid microclimates.
Our high-solid acrylic adhesive:
- Maintains bonding strength in high humidity
- Resists condensation impact
- Prevents edge lifting after long transit
- Leaves no residue
Even after 45-day simulated shipment testing, adhesion remains stable.
3️⃣ Stable Performance for Automatic Sealing Lines
Large PV factories operate high-speed packaging lines.
TONGXIE tape offers:
- Consistent thickness tolerance
- Smooth unwinding
- No core collapse
- Reduced roll replacement frequency
This improves line efficiency and lowers labor downtime.
Case Study: Southeast Asia PV Exporter
A solar module manufacturer exporting to Europe faced:
- 1.2% carton corner lifting
- Moisture-related adhesive weakening
- Increased insurance inspection frequency
After switching to TONGXIE 60mic heavy-duty OPP tape:
- Carton failure reduced to 0.6%
- Improved pallet stacking stability
- Reduced annual logistics claims by 18%
For high-value shipments, small improvements translate into major savings.

FAQ for Solar Module Exporters
Q1: Is 50mic enough for PV carton sealing?
For standard module cartons, we recommend 55–60mic for optimal balance between strength and cost.
Q2: Can it withstand long ocean freight?
Yes. Our adhesive formulation is optimized for high humidity and long transit conditions.
Q3: Do you supply jumbo rolls?
Yes. 1280mm × 4000m jumbo rolls available for regional converters.
Q4: Can you support customized branding?
Yes. Printed tape is available for branding and anti-counterfeit purposes.
