Simple Identification Methods for Common Plastics Prior to the use of various plastic recycling methods for waste plastic recycling, most plastics require sorting. Because the plastic consumption channels are many and complex, some plastic consumption is difficult to distinguish through the appearance of simple, so, can be marked on the plastic products of material types. The American Plastics Association (SPE) proposed and implemented the material variety labeling law, China formulated GB/ T16288-1996 "Plastic Packaging Product Recycling Labeling", although the above labeling method is easy to identify, but due to China's existing unlabeled plastic products are many, it is difficult to identify, in order to distinguish different varieties of degradable plastics, In order to sort and recycle, the first step is to have the knowledge to identify the different biodegradable plastics.

Appearance identification:
 

Look from plastic appearance, can distinguish plastic products to belong to thermoplastic, thermosetting or elastomer kind preliminarily. There are two types of common thermoplastics: crystalline and amorphous.
