Is Cling Film Recyclable?

Cling film is a widely used kitchen item, but its disposal raises environmental concerns. While technically recyclable under certain conditions, cling film is rarely accepted in household recycling systems.

Most cling film¹ is made from LDPE or PVC², plastics that require specialized recycling processes. These are not commonly available to the public, making cling film effectively non-recyclable for most households.

Though the plastic can be reprocessed, its physical properties cause significant issues in recycling facilities³. The material’s thin, flexible nature leads to machinery tangling, which can halt operations and require manual removal. Additionally, cling film is often contaminated with food residue, further complicating recycling and increasing the risk of contaminating other materials like paper.

Why Cling Film Is Not Accepted in Household Recycling

Despite being plastic, cling film is rejected from curbside recycling due to both mechanical and contamination issues.

Its flexible structure disrupts sorting machinery, and residual food waste can compromise entire batches of recyclables, especially paper.

Mechanical Interference at Recycling Facilities

Material Recovery Facilities⁴ (MRFs) use automated equipment to sort recyclables. Cling film poses a threat due to:

• Tangler Risk: Cling film and similar soft plastics wrap around rotating machinery designed for sorting more rigid materials.
• Operational Disruptions: These tangles can force shutdowns, requiring labor-intensive removal and cleaning, which reduces efficiency and increases costs.

Risk of Contamination

Even if the material could be mechanically sorted, cling film's use in food storage introduces contamination risks:

• Food Residue: Oils, sauces, and crumbs are difficult to clean from cling film and can interfere with the recycling of other materials.
• Spoiled Recyclables: Contaminated items, especially paper or cardboard, may be deemed unsuitable for reuse, resulting in more waste.

Comparing Cling Film to Other Plastics

Different plastic types vary in how easily they can be recycled at home. The table below outlines common examples:

Plastic Item	Plastic Type (Code)	Recyclable at Home?	Why or Why Not?
Water Bottle	PET (1)	Yes	Rigid structure, easily sorted and cleaned. High value.
Milk Jug	HDPE (2)	Yes	Rigid, clean, and widely recyclable.
Yogurt Cup	PP (5)	Varies by City	Rigid but less valuable; acceptance is expanding.
Cling Film	LDPE (4) or PVC (3)	No	Too flexible, causes equipment issues, often contaminated.

Alternatives to Cling Film

Since recycling is not a viable option for cling film, alternative materials are recommended—either reusable or more easily disposable.

Reusable options include silicone lids, beeswax wraps, and glass containers. For single-use needs, clean aluminum foil and certain compostable films are preferable.

Reusable Alternatives

Reusable products offer the most sustainable and long-term solution.

1. Silicone Lids: Flexible, durable, and dishwasher-safe. They create airtight seals on various containers.
2. Beeswax Wraps: Made from cotton coated with beeswax, these wraps are moldable, washable, and compostable.
3. Glass or Stainless Steel Containers: These are long-lasting and eliminate the need for wrap-style storage altogether.

Better Disposable Choices

When disposables are necessary, more sustainable options include:

• Aluminum Foil: Recyclable if clean and formed into a compact ball to aid sorting.
• Parchment or Butcher Paper: Biodegradable and compostable when not heavily soiled.

Role of Manufacturers in Reducing Plastic Waste

Beyond consumer action, manufacturers play a crucial role in reducing plastic pollution.

Companies like BagMec® contribute by designing machines that can process biodegradable films⁵, improve recycling compatibility, and enable production of sustainable packaging.

Conclusion

Cling film is technically recyclable but not suited to standard household recycling due to its flexibility and contamination risks. Replacing it with reusable or more recyclable materials is a more sustainable option. Manufacturers like BagMec® play an important role by producing machines that support the development and use of environmentally friendly packaging.
