The packaging industry is increasingly focused on sustainability, with packing tape emerging as an essential item under scrutiny. Traditional packing tapes, commonly made from polypropylene or PVC, contribute to plastic waste and can hinder the recyclability of packaging materials.
As consumers and regulators push for more sustainable practices, innovative solutions in packing tape design are addressing the environmental impact of this everyday product.

From biodegradable adhesives to recyclable materials, here’s how packing tape is evolving to meet eco-friendly demands.
1. The push for eco-friendly materials
The drive towards sustainable packing tape often begins with the materials. Most conventional tapes are made from non-biodegradable plastics like polypropylene or polyester, making them challenging to recycle alongside paper-based packaging.
However, new tape solutions are emerging with materials that are either recyclable or biodegradable. For instance, paper-based packing tapes, often reinforced with fibres for added strength, are increasingly popular due to their compatibility with paper recycling streams.
These tapes can easily be recycled with cardboard boxes, reducing the need for separation during the recycling process.

By GlobalDataIn addition to paper-based solutions, compostable tapes are also gaining traction. Made from plant-based materials like cellulose, these tapes can break down naturally in composting environments, offering a waste-free solution for eco-conscious businesses.
Some brands have even developed tape that meets industrial composting standards, meaning it will decompose in commercial composting facilities without leaving harmful residues.
2. Advances in sustainable adhesives
While the backing material is crucial, the type of adhesive used also significantly impacts a tape’s environmental footprint. Conventional tapes typically use synthetic adhesives derived from fossil fuels, which are not biodegradable.
However, newer sustainable tapes utilise adhesives made from renewable resources, such as natural rubber or plant-based compounds. These alternatives provide comparable stickiness and durability without contributing to plastic pollution.
Water-activated tape (WAT), commonly known as gummed tape, represents another eco-friendly adhesive option. Unlike pressure-sensitive tapes, which rely on non-biodegradable adhesives, WAT uses a water-activated starch adhesive that bonds strongly with cardboard.
This type of tape creates a secure seal that is tamper-evident and ideal for high-stakes shipping, and it is also fully recyclable. Due to its enhanced security and sustainability, WAT is becoming a preferred choice for e-commerce businesses aiming to reduce their environmental impact.
Another emerging trend is the development of solvent-free adhesives. Traditional tapes often use solvent-based adhesives, which emit volatile organic compounds (VOCs) during manufacturing and application, impacting air quality and human health.
Solvent-free adhesives, in contrast, are made with safer, water-based formulations that reduce VOC emissions, making them a greener choice for both production and end-users.
3. Supporting a circular economy with recyclable tapes
As the packaging industry shifts towards circular economy principles, recyclable packing tapes play an essential role. A circular economy prioritises keeping materials in use for as long as possible, reducing the need for virgin resources and minimising waste.
Recyclable tapes are designed to be compatible with existing recycling processes, particularly paper and cardboard recycling streams, which are widely available and efficient.
Some companies are now offering polypropylene tapes with modified formulations that allow them to be recycled alongside cardboard. These tapes are designed to break down into small, manageable particles during the pulping process, ensuring they do not interfere with the recycling of cardboard fibres.
By enabling the seamless recycling of entire packages, these tapes contribute to a more efficient and sustainable waste management system.
The benefits of sustainable packing tape solutions extend beyond environmental impact, as they also offer competitive advantages. Businesses that prioritise eco-friendly packaging practices can attract environmentally conscious consumers, enhancing brand loyalty and reputation.
Moreover, with increasing regulation around packaging waste and plastic usage, companies adopting sustainable tapes are better positioned to comply with forthcoming legislation.
For example, the European Union and UK governments have introduced stringent recycling requirements that impact packaging materials, with similar trends emerging globally.
Challenges and the road ahead
While sustainable packing tapes offer promising solutions, challenges remain. For one, many eco-friendly tapes come at a higher cost than traditional options, which can deter smaller companies from making the switch.
Moreover, sustainable tapes may require specialised equipment for application, particularly water-activated tapes, which need water dispensers for efficient use.
Consumer education is another crucial factor in driving adoption. Many end-users may not be aware of the environmental benefits of sustainable tapes or how to dispose of them correctly.
Clear labelling and information campaigns can play a role in educating consumers on sustainable options, ensuring that eco-friendly tapes are used and disposed of effectively.
Finally, research and development continue to play a significant role in advancing the capabilities of sustainable tapes. Innovations are constantly being made in biodegradable adhesives and renewable materials, driving the industry closer to fully sustainable tape options that meet the functional needs of today’s high-speed, high-volume packaging operations.
The takeaway
Sustainable packing tape solutions are rapidly evolving to meet the demands of an eco-conscious market. With options such as recyclable polypropylene, biodegradable adhesives, and water-activated tapes, the industry is making significant strides in reducing its environmental footprint.
While challenges remain, including cost and user awareness, the benefits of sustainable packing tape – from supporting recycling efforts to complying with environmental regulations – make it an essential component in the future of eco-friendly packaging.
As businesses and consumers alike embrace these innovations, sustainable packing tape is well on its way to becoming a standard rather than an exception in packaging operations worldwide.
