Rethinking plastic wrap in packaging
Plastic wrap · Packaging Gateway

Plastic wrap has been a staple in packaging for decades, offering durability, flexibility, and a high level of product protection.

But as environmental awareness grows, the packaging industry is re-evaluating the role of plastic wrap, considering its environmental footprint and exploring alternative materials.

This shift is reshaping not only packaging practices but also how companies align with sustainability goals.

In this article, we examine why plastic wrap is under scrutiny, assess emerging alternatives, and discuss what the future of plastic wrap might hold for the packaging industry.

The environmental impact of plastic Wrap

Plastic wrap, often made from low-density polyethylene (LDPE), has traditionally been favoured for its versatility and barrier properties, which prevent moisture and air from damaging products.

While these qualities make plastic wrap ideal for protecting goods, LDPE and similar materials are challenging to recycle and contribute to the accumulation of plastic waste in landfills and oceans.

Statistics underscore the environmental challenge. It is estimated that plastic packaging accounts for nearly 40% of global plastic demand, with a significant portion of this waste not being recycled. In the UK, for instance, packaging materials, including plastic wrap, comprise a major part of the 2.2 million tonnes of plastic waste produced annually.

As only a fraction of this waste is effectively recycled, much of it ultimately adds to pollution.

The durability of plastic, while beneficial in packaging, becomes a problem post-use, as these materials can persist in the environment for hundreds of years.

For businesses and consumers alike, the demand for more sustainable packaging solutions has become a driving factor for change, putting pressure on the packaging industry to innovate and reduce its reliance on traditional plastic wrap.

Emerging alternatives: redefining wrapping materials

In response to environmental concerns, companies are exploring innovative alternatives to conventional plastic wrap, aiming to reduce the environmental impact while maintaining essential protective qualities. Here are a few alternatives gaining traction in the packaging sector:

  1. Biodegradable films: Unlike traditional plastic, biodegradable films break down naturally, often using plant-based materials like polylactic acid (PLA) derived from corn starch or sugarcane. These films decompose more quickly than standard plastics and offer similar strength and flexibility. However, challenges remain, such as the need for specific conditions for decomposition and the limited infrastructure to process these materials effectively.

  2. Compostable wraps: Made from natural materials such as cellulose, compostable wraps can decompose entirely in a composting environment. Many brands are now developing compostable packaging that can break down safely without releasing harmful residues. The shift to compostable wraps offers a solution with minimal environmental impact, but questions around durability and the cost of scaling production still need to be addressed.

  3. Recyclable multi-layer films: Some manufacturers are rethinking plastic wrap by developing recyclable multi-layer films, which blend various polymers to create a wrap that can still be recycled after use. These advanced films provide the same benefits as traditional plastic wrap but have a reduced environmental footprint, as they can be recycled through appropriate systems.

  4. Reusable wrap solutions: Some companies are experimenting with reusable wrapping materials, especially for larger items in industrial packaging. Materials such as woven polypropylene offer durability and can be reused multiple times before disposal, thus reducing waste significantly. While not a solution for all packaging, reusables are gaining traction in areas where products require robust protection for longer periods.
