What do you mean by grade 1, class two or class three in plastic?
Two material is that the raw material has been used once, but high pressure granulation except high-pressure granulation using imported large majority, if import large industrial film has not been exposed to the weather, so the quality is very good, the processed particles with good transparency, then it should be judged according to the brightness and surface whether the rough particles.
A material refers to the raw materials used for scrap without landing, or called under the angle of material, some material floolwing, plastic head material, quality is also quite good, is not used, in the process of new material processing, while the remaining small angle, or the quality of the raw materials. The particles which are made of the wool have better transparency and can be compared with the new material, so they are grade materials or superfine materials.
Three grade material refers to the raw material has been used two times or more times, the processing of particles, and its elasticity, toughness and other aspects are not very good.
