The edible oil industry forms one of the largest and fastest-growing segments of the FMCG sector in India and across global markets. From sunflower and soybean oil to premium olive oil, these products are consumed daily in households, restaurants, and food industries. But beyond quality production, packaging plays a critical role in protecting oil freshness, extending shelf life, and ensuring efficient distribution across supply chains.
Among the various packaging innovations, 28mm PET preforms have emerged as the gold standard for edible oil bottles. Their ability to combine freshness protection with efficiency in FMCG logistics makes them indispensable for brands that prioritize both consumer satisfaction and operational savings.
PET preforms are essentially small, test-tube shaped pre-bottles manufactured using food-grade PET (Polyethylene Terephthalate). These preforms undergo blow molding to form bottles of different shapes and capacities.
By using standardized preforms, manufacturers ensure consistency in packaging, compatibility with capping machines, and cost efficiency.
Edible oils are prone to oxidation, rancidity, and nutrient loss if exposed to oxygen, moisture, or sunlight. 28mm PET preforms are designed to combat these challenges:
The dense molecular structure of PET offers excellent resistance against oxygen penetration and water vapor absorption. This prevents oil spoilage and ensures the product retains its original aroma and taste.
For oils rich in Vitamin E, Omega-3, and antioxidants (e.g., sunflower, olive oil), exposure to light can degrade quality. Colored preforms (amber/green) act as UV shields, extending shelf stability.
The 28mm threaded neck ensures compatibility with tamper-evident caps and induction seals, preventing leakage during transportation and guaranteeing product integrity until it reaches consumers.
By minimizing oxygen ingress, moisture contact, and UV degradation, preforms extend edible oil shelf life by weeks or even months, critical for FMCG brands distributing across long distances.
Beyond freshness, FMCG companies require packaging that enhances operational efficiency. PET preforms deliver multiple advantages:
Compared to glass bottles, PET bottles derived from preforms weigh significantly less. This reduces shipping costs and lowers carbon emissions.
Preforms occupy less storage space compared to fully blown bottles. Manufacturers and distributors save on warehouse costs and optimize truckloads.
Preforms can be converted into bottles at high speed using automated blow molding lines, supporting large-scale FMCG operations.
The standard 28mm neck finish fits seamlessly with automated filling, sealing, and labeling systems, ensuring efficiency on high-speed bottling lines.
PET is 100% recyclable. Brands can incorporate rPET (recycled PET) into preforms to meet sustainability goals while reducing dependency on virgin plastics.
For edible oil manufacturers, adopting 28mm preforms delivers both consumer-facing and backend benefits:
One of India’s leading sunflower oil brands shifted from glass bottles to 28mm PET preforms. The result was:
This shift not only improved efficiency but also aligned with the company’s sustainability goals.
As FMCG evolves, edible oil packaging will see further innovations:
The shift towards 28mm edible oil bottle preforms represents a milestone in FMCG packaging. By combining freshness protection with supply chain efficiency, they offer a strategic edge to brands competing in a highly saturated market.
For manufacturers, these preforms deliver cost savings, sustainability, and operational speed. For consumers, they ensure that every drop of edible oil remains as fresh and nutritious as intended.
In short, preforms are not just packaging—they are a vital tool for growth, efficiency, and trust in the edible oil FMCG sector.
