Moisture-Proof Coating Corner Guard

The production process for Moisture-Proof Coating Corner Guard is similar to our waterproof wax-impregnated cartons. We use food-grade paraffin or microcrystalline wax to impregnate the surface. This wax treatment not only forms a protective film on the surface but also penetrates the cardboard fibers, achieving molecular-level waterproofing while also enhancing strength and structure.

Product Advantages

The moisture-proof wax coating on the paper corner guard ensures that it maintains its structural strength even in high-humidity environments or during cold chain logistics, transportation, and storage. Unlike ordinary cardboard packaging, it resists moisture penetration, deformation, or even cracking.

We use recyclable kraft paper as the base material, and the glue and wax coatings comply with international packaging standards, making them directly recyclable and compostable.

Product Applications

We have conducted more targeted testing for our frequent clients. If your product or storage environment meets these requirements, you may also consider our Moisture-Proof Coating Corner Guard for packaging protection.

The first application is cold chain logistics. It can be purchased with wax-impregnated waterproof cartons. After all, cold chain transportation requires not only waterproofing but also low-temperature resistance, placing even higher demands on waterproofing and moisture-proofing. Our paper corner guards and cartons will not crack even at -40°C.

The second application is ocean shipping, especially long-distance shipping or routes through tropical regions. These routes are subject to high humidity and sometimes salt spray. Our paper corner guards have undergone at least 15 days of simulated environmental testing and have maintained their strength.

Besides these two logistics and transportation scenarios, this product can also be used in warehouses with high humidity.
