Below are the standard processing steps employed in the fabrication of plastic packaging products for the packaging industry:

1. Resin Processing: Raw plastic resins such as polyethylene, polypropylene, PET, etc., undergo drying, blending with additives, and melting in extruders to create a uniform molten polymer.

2. Film Extrusion: The molten plastic is extruded through a flat die to produce a broad sheet or tubing. It is then cooled, stretched, and flattened into a thin plastic film roll.

3. Blow Molding: Molten plastic is injected into a mold cavity, and compressed air is introduced to inflate and shape it into hollow containers like bottles or jars.

4. Injection Molding: Heated plastic is injected into a mold cavity at high pressure to adopt the desired shape. This process is used for manufacturing intricate products such as caps, lids, and closures.

5. Thermoforming: Plastic sheets are heated, molded into shape using matched mold tools, and then trimmed to craft shallow trays and containers.

6. Printing & Decorating: Digital or flexo printing techniques are utilized to apply brand identities and safety information. Laminating is employed to enhance barrier properties.

7. Cutting & Trimming: Plastic rolls or sheets are cut, punched, or notched using tools like scissors, lasers, or dies to create specific shapes.

8. Assembly: Individual components are brought together to form the final packaging product using methods such as adhesives and heat sealing.

9. Finishing: The products undergo a final round of inspection, cleaning, and packaging before being dispatched to end users.

These processes are instrumental in the large-scale production of plastic packaging shapes and configurations with accuracy, consistency, and cost-effectiveness to cater to a variety of product protection and branding requirements.
