A PET Bottle Manufacturing Unit is a small to medium scale enterprise that manufactures bottles using polyethylene terephthalate resin. The production process involves resin procurement, preform making, injection molding or blow molding, heating, forming bottles, cooling, trimming, quality inspection, and packaging. PET bottles are valued for their lightweight strength, transparency, chemical resistance, and recyclability, making them ideal for packaging water, juices, soft drinks, edible oils, and pharmaceutical liquids. The unit requires moderate investment in machinery such as injection molding machines, blow molding machines, preform making units, trimming and finishing equipment, and packing machines, along with skilled and semi skilled labor. With growing demand for safe and attractive packaging, PET bottles have consistent market potential in retail, industrial, and export sectors. By producing high quality bottles with precise dimensions and finishes, the unit can achieve steady demand, repeat orders, and good profitability, while also exploring opportunities for custom printing, branding, and bulk supply contracts.
