We all know that the plastic products can be sorting and recycling are very necessary to us. It could be conserve the resource and protect the enviorment from plastic pollution and greenhouse gas emissions. It can be reprocessing of plastic waste into new an useful products.

Normally the manufacture will be mark the plastic recycling symbol in their plastic products of bottom. It will helps us to identify the plastic products can be for sorting,and reminder us to recycling.

Here have 6 different plastic raw material for the plastic identification code:

Plastic identification code

Type of plastic polymer



Polyethylene terephthalate(PET)

Clarity, strength, toughness, barrier to gas and moisture


High-density polyethylene(HDPE)

Stiffness, strength, toughness, barrier to gas and moisture


Polyvinyl chloride(PVC)

Versatility, ease of blending, strength, toughness.


Low-density polyethylene(LDPE)

Ease of processing; strength; flexibility; ease of sealing; moisture barrier.



Strength; resistance to heat, chemicals, grease and oil; moisture barrier.



Versatility, clarity, easily formed, easily foamed

The identification code for the plastic products

These resin identification codes, often abbreviated RICs, are used internationally. It was administered by a standards organization of ASTM international since 2008. The PP raw material are in the recycling code of 5, which means is recycling. We are adopting the raw metrial of PP(polypropylene) to producing the various types of the plastic products, like plastic bucket, plastic pail, plastic bottle, plastic jar. And those could be recycling for times. It is eco-friendly raw material. Each of the plastic bucket strictly complies with the requirement of national quality standards.

The plastic products can be recycling is very important for daily life. We are using it to packing many different staffs, like food and other things. Specially, we all are very concern the food safety and health. The PP raw material also can be producing the food grade packing products, it helps us to keep the food fresh and storage, and those are offering more packing solution for us.
