NWJ113 Modified Asphalt Polyethylene-Reinforced Waterproofing Membrane

Packaging, Storage, and Transportation

Packaging: Sealed in special packaging film.
Storage: Products of different types and specifications should be stacked separately and must not be mixed. Protect from direct sunlight and rain, and ensure adequate ventilation. The storage temperature should not exceed 45°C. Rolls should be stored flat, with stacks no higher than three layers. Under normal transportation and storage conditions, the product has a shelf life of one year from the date of manufacture.
Transportation: Prevent tilting or lateral pressure; handle with care when loading and unloading; do not throw the cargo; cover with a tarp if necessary.

Applicable Standard: GB 18967-2009 “Modified Asphalt Polyethylene-Reinforced Waterproofing Membranes”
