Edible oil processing—including mustard oil, rice bran oil, soybean oil, sunflower oil, and ghee (clarified butter)—is one of Eastern India’s largest consumer staple sectors. Packaging liquid fats and oils presents two major technical hurdles: leak prevention during transport and oxidative rancidity prevention under ambient light and temperature storage.
Why Standard Single-Layer Plastics Fail for Oils
Single-layer polyethylene (LDPE) pouches are porous to oxygen and susceptible to environmental flex-cracking. When liquid oil pouches are packed into plastic crates and transported over rough roads, micro-pinholes form at film flex points, causing oil seepage that damages entire shipping crates. Furthermore, oxygen ingress reacts with unsaturated fatty acids, causing rancid odors, off-tastes, and shortened shelf life.
5-Layer & 7-Layer Co-Extruded Film Architecture
At Tirupati Traders, we manufacture high-performance multi-layer co-extruded barrier films utilizing specialized barrier polymers:
- Polyamide (Nylon) Core Layers: Nylon provides unmatched mechanical toughness, puncture resistance, and flex-crack resistance, eliminating pinhole leaks during transport.
- EVOH (Ethylene Vinyl Alcohol) Oxygen Shield: EVOH delivers extraordinary oxygen barrier performance (over 10,000 times higher oxygen barrier than standard PE), preventing oil oxidation and extending shelf life up to 12 months.
- High Hot-Tack LLDPE Sealant Layers: Formulated with metallocene PE resins to deliver instant, high-strength heat seals capable of sealing through liquid oil residue on machine jaws.

Frequently Asked Questions (FAQ)
Can your oil pouch films run on high-speed automatic filling machines?
Yes. Our co-extruded oil films are engineered with precise slip additives for smooth web movement on high-speed liquid vertical form-fill-seal (VFFS) machines.
How do you prevent light-induced oxidation in ghee?
We offer white-opaque or metallized lamination options that block UV and ambient light from degrading ghee fats and vitamin content.
