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.
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: milk bottle, water bottle, disposable cups, etc.|
PLA: plastic cup, ice-cream cup, salad box
Melamine: disposable tableware
