Recyclable Plastic Material

Products which are made with plastic can be found everywhere in our daily life, the features of plastic including light-weight and low cost make it indivisible part of our life in this era, but meanwhile, it results in the over-utilization of plastic which causes serious environmental problem in these decades. 

Identification Code

Thus "Society for the Plastic Industry" promoted the importance of recycling plastic products and developed a set of recycling guideline, each product with Resin Identification Code on it can be recycled.
Recyclable plastic material can be grouped into seven categories, the is based on the feature of material, heat resistance, etc. 

Resin Identification Code	Material	Feature	Heat-Resistance Temperature(℃)	Usage
	Polyethylene Terephthalate(PET, PETE)	High hardness and toughness, lightweight, involatile, acid and alkali resistance	60~85	plastic bottles, juice and drink bottles, oil buckle, etc.
	High-Density Polyethylene (HDPE, PEHD)	Corrosion resistance, acid and alkali resistance	90~110	Plastic bags, translucent or opaque plastic bottles, etc.
	Polyvinyl Chloride (V, PVC)	High-plasticity	60~80	food wrap, plastic egg carton, plastic Spice jar, etc.
	Low-Density Polyethylene (LDPE)	Corrosion resistance, acid and alkali resistance	70~90	Plastic bags, translucent or opaque plastic bottles, etc.
	Polypropylene (PP)	Acid and alkali resistance, chemical resistance, impact resistance, high temperature resistance	100~140	plastic disposable cups, pudding cups, soy milk bottles, etc.
	Polystyrene (PS)	low water absorption, stability	70~90	plastic bottle, ice-cream cup, instant noodle bowl, etc.
	Other plastic material (OTHER, O) e.g., Polycarbonate (PC) Polylactic Acid (PLA) Melamine resin (Melamine)	PC: lightweight, transparent, high mechanical strength, high temperature resistance PLA: lightweight, transparent Melamine resin: high temperature resistance	PC: 120~130 PLA: ≒50 Melamine: 110~130	PC: milk bottle, water bottle, disposable cups, etc. PLA: plastic cup, ice-cream cup, salad box Melamine: disposable tableware
