Mark
The package of products should have clear and firm mark.
It includes manufactory name, product name,date of manufacture or lot number, net volume, standard number, avoid direct sunlight and rain markings of GB/T 191, etc.
Packing
Products’ sealed package has two layers
The inner one is black polyethylene vacuum package and the outside is carton.
Transportation
In the transportation process, avoid isolation, rain
Take care of products to prevent packing damage.
Storage
Store in shade, ventilated and dry storehouse
Avoid pile up in open air and under direct sunlight.
Security
Styrene-butadiene rubber granule stores in vacuum package.
It easily causes self-ignition if left untouched for long periods of time after open it, therefore, timely seal up it.
