Blow molding machine is a versatile manufacturing process used to produce hollow plastic parts, such as bottles, containers, and industrial products. The most commonly used plastics in blow molding include:

1. HDPE (High-Density Polyethylene)

Features: High strength, chemical resistance, lightweight, and recyclable.

Applications: Milk jugs, detergent bottles, fuel tanks, and industrial containers.

2. PET (Polyethylene Terephthalate)

Features: Excellent clarity, lightweight, strong barrier properties (for CO₂ & oxygen).

Applications: Beverage bottles (water, soda), food packaging, and cosmetic containers.

3. PP (Polypropylene)

Features: Good chemical resistance, flexibility, and heat resistance.

Applications: Pharmaceutical bottles, food containers, and household product packaging.

4. LDPE (Low-Density Polyethylene)

Features: Flexible, impact-resistant, and good for squeeze bottles.

Applications: Cosmetic tubes, squeeze bottles, and lightweight packaging.

5. PVC (Polyvinyl Chloride – Less Common Due to Environmental Concerns)

Features: Rigid or flexible (with plasticizers), good clarity.

Applications: Medical bottles, shampoo bottles (declining due to recycling challenges).

6. PC (Polycarbonate – Used in Specialized Applications)

Features: High impact resistance, transparency, and heat resistance.

Applications: Large water bottles, medical devices, and automotive parts.

7. ABS (Acrylonitrile Butadiene Styrene – Less Common for Blow Molding)

Features: Tough, impact-resistant, good for structural parts.

Applications: Automotive components, industrial housings.

8. Recycled Plastics (rPET, rHDPE, etc.)

Features: Eco-friendly, cost-effective, and increasingly used in sustainable packaging.

Applications: Recycled bottles, containers, and industrial products.
