• PET is clear, tough, and has good gas and moisture barrier properties, resistance to heat.
• Commonly used in bottles and many food and non-food containers.
• Stiffness, strength, toughness, ease of processing, and ease of forming.

• Soft drink
• Water
• Sports drink
• Beer
• Mouthwash
• Catsup and salad dressing bottles
• Pickle, jelly and jam jars
• Cosmetic bottles

• Unpigmented bottles are translucent, have good barrier properties and stiffness, and are well suited to packaging products with a short shelf life.
• HDPE has good chemical resistance, it is used for packaging many household and industrial chemicals.
• Pigmented HDPE bottles have better stress crack resistance than unpigmented HDPE bottles.

• Liquid laundry detergent
• Shampoo conditioner
• Motor oil bottles
• Milk and juice bottles
• Yogurt and margarine tubs

• Poor heat stability, molding and decomposition temperature range are similar.
• Poor fluidity, poor molding appearance.
• Corrosive to mold.
• Most easy to burn and generating acid gas.
• Good strength, electrical insulation and chemical resistance.
• Can softened after adding DOP.
• Poor heat resistance.
• High sp. Gravity (1.4) has burning resistance; good for printing
• Different formula has different characteristics. Wide in application range, low price, high impact on environment. Likely to decompose when molding temp isexceeding 190°C and emit corrosive gas of HCI.

• High shrinkage, easy to bend and deform.
• Need cooling time, poor molding yield.
• Sink will occur to product, need forceful mold releasing.
• Molding shrinkage is highly affected by mold temperature. Poor stability.
• Good fluidity, good heat stability, but molecular orientation lead to distortion.
• Lighter than water, soft.
• Not heat resistance, adhesive printing.

• Low fluidity, flow mark appears if filling were poor, when pressure is not enough, easy to have dent, need high-pressure molding.
• In optical use, transparency is a problem, when mixing with other material; care shall be given to decomposition.
• Excellent in molding property, mechanical strength is better than PE.
• Good water, chemical resistance and electrical insulation.
• Easy to distort, deform and dent.
• Adhesive, the lightest plastic.
• Low Sp. Gravity (about 0.90), FDA grade, good, transparency, not moisture absorption, low price, heat resistance and normal mechanical strength are poor, low foaming percentage, poor for printing.

• Catsup bottles
• Yogurt containers
• Margarine tubs
• Medicine bottles

• Of ethylene family, general plastic resin.
• Good fluidity, good molding yield and molding property.
• Easy to break, not good impact resistance.(GPPS)
• Easy to have trim.
• Colorless, transparent, easy to be dye, good insulation.
• Good in water resistance and chemical resistance.
