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
Ji-Horng Plastic 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.
Ji-Horng Plastic High-Density Polyethylene (HDPE, PEHD) Corrosion resistance, acid and alkali resistance 90~110 Plastic bags, translucent or opaque plastic bottles, etc.
Ji-Horng Plastic Polyvinyl Chloride (V, PVC) High-plasticity 60~80 food wrap, plastic egg carton, plastic Spice jar, etc.
Ji-Horng Plastic Low-Density Polyethylene (LDPE) Corrosion resistance, acid and alkali resistance 70~90 Plastic bags, translucent or opaque plastic bottles, etc.
Ji-Horng Plastic Polypropylene (PP) Acid and alkali resistance, chemical resistance, impact resistance, high temperature resistance 100~140 plastic disposable cups, pudding cups, soy milk bottles, etc.
Ji-Horng Plastic Polystyrene (PS) low water absorption, stability 70~90 plastic bottle, ice-cream cup, instant noodle bowl, etc.
Ji-Horng Plastic 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
