Comprehensive Plastic Manufacturing Services

The core of the business lies in the extrusion of mono and co-extruded low and linear low-density polyethylene films. We specialize in creating wide-width sheeting, a capability pioneered by the company over forty years ago. This technical expertise allows us to produce materials for a variety of critical applications, from heavy-duty industrial sacks to precision liquid packaging. Our production team handles everything from raw resin to finished, printed rolls, guaranteeing traceability and consistent quality.

Packaging Solutions

Our packaging division provides flexible materials tailored for fast-moving consumer goods (FMCG), industrial products, and agricultural outputs. We manufacture side, bottom, and spine seal bags, gusseted bags, and sheeting designed for automatic form-fill-seal machines. We also produce high-tensile pallet wrap, shrink wrap sleeves, and shrouds that offer superior load stabilization for cement, glass, and beverage industries.

Agricultural & Geosynthetic Products

Swazi Plastic Industries has been a market leader in plasticulture for more than twenty-five years. Our agricultural films are developed to optimize crop yields, reduce water consumption, and protect valuable harvests. We were the first company in the region to manufacture products like greenhouse films, plastic mulch, hydroponic membranes, and wide-width silage covers, making us a key partner for the modern farming community.
