How to identificated the plastic recycling labeling for the plastic product?(一)


Plastic Recycling Labeling was developed by the Plastics Industry Association in 1988.The recycling labeling will marked it in the container or package from number 1 to 7 in the triangular symbol.Each container has a small ID card which will helps people easy to know which material can be recycling and how to usage in the different products.Each number had represented with different material.Here will introduce the number from 1 to 7 to you.

Recycle 1

Number 1 : PETE (Polyethylene terephthalate). 

PETE with high melting point,and the heat resistance is only reach to 70℃,easy to deform.It can not packing with oil,alcohol and other substance.When the inside commodity’s temperature is higher,it may will increase the harmful substance dissolution,and easy to distort contraction.Normally we will reuse the plastic bucket.But if reuse thus plastic bucket,it will releases the carcinogen DEHP.It will harmfull for people’s health.


Number 2 : HDPE (High Density Polyethylene). 

HDPE container do not recycling if cleaning is not thorough.Normally it will be packed with detergent,shampoo,bath lotion,edible oil,pesiticide and so on.And don’t use it as drinking glass or storage container for other products.


Number 3 : PVC (Polyvinyl Chloride).

PVC with excellent plasticity and low price,it is widely used.The heat-resistant only reach to 81℃.It will release the bad substance when with high temperature,so it is rarely used for food packaging.Difficult to clean and easy to residue,do not recycle.Normally it will use for the raincoat,building materials,plastic film,plastic boxes and so on.


Number 4 : LDPE (Low Density Polyethylene). 

LDPE widely use to make the plastic bags,fresh-keeping film,plastic film.Don’t put the fresh-keeping film into the microwave.As it will release the harmful substance when it with high temperature.If the toxic substance with food go into the body,it will cause the diseases.
