4 Recommended Waterproof products!


Looking for good waterproof products?


We Hagihara Industries is a leading manufacturer of blue tarp in Japan.

Not only blue tarp that we are good with,  but we manufacture many products that are made out of polyethylene.



Let us proudly introduce our Waterproof products!


First one is Aqua pressure #7000.



What is amazing about this product is that it has 5 years of weather resistance

and it has 2.5 times the thickness (24 mil)  of core weave

It is suitable for long term waterproof use.


Next up is X-water 7100



We have an achievement in selling X-water 7100 as an water tank liner

to store agricultural water in Australia and India.

Not only for agricultural water but it is certified to NSF/ANSI 61, so it can be used to store drinking water.

You may think it weigh a lot as it is strong enough to store water,


we use polyethylene instead of PVC so it is light and strong!

Another good point about this product is that it is easy to fabricate and has good welding performance.

We are more than happy to custom to your size, so please feel free to contact us.
