"These are light-blocking protective mats we have developed for use in Industrial Waste Final Disposal Site by leveraging the features of Needle Punched MARIX. The mats are superior not only in strength and weather resistance but in elongation, cushioning property, and light-blocking performance as well. They are used as protective buffering materials that can protect against even deformed protrusions. LN650 and L1500 are three-layer mats that use a polyethylene laminated layer on the top surface and ELEVES (polyethylene sheath and polyester core) on the rear surface, which can be bonded together using a self-propelled hot wind pressure welding machine. Their bonding performance is excellent."
