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 insolation, 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.
