“Sun Plastics manufactures medium and high-barrier food packaging in Southern Africa, including vacuum bags, lidding films, base films, and dairy packaging built for local conditions.”
The dairy industry across Southern Africa is evolving, and so are the packaging demands that come with it. At Sun Plastics, we have been on a deliberate journey to develop barrier film and flexible packaging solutions that genuinely serve this industry. This is where we are in that journey, and what we are seeing in the market right now.
A market with rising expectations
Across the food packaging industry, the bar keeps rising. Retailers and consumers expect longer shelf life, better product visibility, and packaging that performs under real transport and storage conditions. In dairy specifically, this puts enormous pressure on the technical performance of every film used, from maturation through to the point of sale.
Flexible packaging continues to lead the way in food packaging across Southern Africa, valued for its durability, versatility, and cost-effectiveness across a wide range of dairy applications, including cheese, yoghurt, and processed dairy formats. Within this, medium- and high-barrier flexible packaging has become a non-negotiable for producers who need to protect product integrity from the factory floor to the consumer.
Our journey into dairy packaging
A few years ago, Sun Plastics made a deliberate decision to invest in barrier film development for the cheese and dairy industry in Southern Africa. It was not a quick process. R&D takes time, trials demand patience, and entering a market with established players requires consistency and a genuine willingness to learn.
What became clear early on was that dairy packaging is not one-size-fits-all. Each stage of production, maturation, cutting, portioning, and retail packaging carries its own technical requirements. Getting it right meant understanding those requirements from the inside, not just supplying a film and stepping back.
There were challenges along the way. But those challenges led to real improvements in our material constructions, our production processes, and the way we work with clients. We had to earn our place in this market, and we continue to do so.
Dairy & Food Packaging Solutions for Southern Africa
Through this process, we have developed a focused product range built specifically around the needs of dairy producers.
Cheese Maturation Bags
Purpose-built for the ageing process, our cheese maturation bags are available in medium (PA) or high (EVOH) barrier options and can be custom-sized to fit your machinery. A spine and K-seal design adds structural integrity, supporting longer maturation periods while retaining aroma and ensuring freshness. Our high barrier option provides a minimum 12-month shelf life, with strong puncture resistance and reliable gas and moisture barrier performance, with easy handling and no sagging.
Base films
Our speciality base films are engineered for deep draw thermoforming applications, available in 7-layer and 9-layer PA/EVOH/PE constructions. Designed for dairy, meat, seafood, and ready meals, these films offer excellent drawdown, strong mechanical properties, and maintain performance even at freezing temperatures. High, medium, and low barrier options are available, with customisable barrier structures and excellent clarity for retail presentation.
Lidding Films
Our PA/EVOH-based 7-layer barrier lidding films are formulated for use on thermoforming form-fill-seal lines and ready-made trays. Available in laminated and plain film options, they deliver strong seal integrity, hot tack performance, and high barrier protection against gas and moisture. Anti-fog and modified atmosphere packaging (MAP) compatibility make these well-suited to retail dairy environments where product visibility and shelf life matter.
Form, Fill and Seal Films
Engineered for high-speed automated packaging lines, our form, fill and seal films offer excellent machinability, reliable seal integrity, and consistent product protection for fresh, frozen, and dry dairy formats. Customisable configurations mean these films can be tailored to vertical and horizontal equipment, a practical choice for dairy producers operating at scale.
How we work with our clients
Our growth in this sector has not happened in isolation. The partnerships we have built along the way have shaped us as much as the R&D has. When a new client transitions to Sun Plastics packaging, a member of our team goes directly to the client’s facility to assist throughout the trial process, from sealing and material integrity testing to road trials and live production approvals. We believe being present and hands-on is the only way to ensure that every step genuinely serves both the packaging and the product. It is an approach that makes transitions smoother and builds the kind of working relationship that lasts.
Serving Southern Africa from the ground up
The global dairy packaging market is projected to grow significantly through 2034 (Insights, 2025), and Southern Africa is part of that story. As dairy producers in this region face increasing pressure to improve packaging performance, shelf life, and cost efficiency, locally produced flexible packaging solutions have a real role to play.
Sun Plastics operates a modern production facility in Botswana using a national warehousing and distribution network in South Africa, serviced by our trucks coming in from Gaborone in Botswana. That footprint means we can serve clients across the region with shorter lead times, reduced logistical costs, and direct on-the-ground support, without the delays and uncertainty that come with importing packaging from overseas.
We are invested in the long game, committed to our materials, our team, and our client relationships, so that we can keep growing alongside the industry we serve.
If you are a dairy producer in South Africa looking for vacuum bags, base films, lidding films, or form, fill and seal packaging solutions, we would welcome the conversation.
