Plastic vs Paper Packaging: The Pros and Cons

Many companies are switching to paper packaging instead of plastic packaging to become more sustainable, especially with the new plastic tax coming into force in 2022. However, switching to paper also has its environmental issues.

For example, cardboard production is water intensive, generates emissions and runs the risk of encouraging deforestation if not sourced sustainably. On top of that it is difficult to recycle if contaminated with food or other waste.

So, are paper and cardboard really more eco-friendly than plastic? Could Bioplastics be the answer to all sustainability problems? In this article, we will look at the bigger picture and explore the pros and cons for both plastic and paper.

We know you are busy, so we decided to put in a quick table with the pros and cons of both plastic and paper, so you can see the clear positives and negatives of each that are discussed further in this article.


Plastics came into existence by accident in 1907, but it grew popular around the 1950s when high-density polyethylene was created. Plastics are made from fossil fuels which is clearly a non-renewable source. It is estimated that 4% of the world’s oil production is used as feedstock to make plastics, so this means plastic is seen as poor material in terms of renewability and sustainability.

The problem is, in modern life we now have such a reliance on plastic that it could be impossible to cut out completely due to the advantages they bring.

The Plastic Pro’s

Although they are bad for the environment, there are a number of reasons why some may find plastics difficult to give up. These are as follows:

  • Low costs: plastic is the cheapest out of all common packaging materials.
  • Excellent Durability: Plastics do not break or get damaged easily and can withstand falls or slight trauma without damage so provides great protection. Plastic packaging often does not get damaged when stacked on top of each other, making transportation of products easier.
  • Long lasting: Plastic takes about a thousand years to break down, they can last for extensive periods without damage. However, as much as this is a pro, it is also a con.
  • Light weight: Most plastic materials weigh almost nothing when compared to alternatives such as glass and wood, which is great in reducing the footprint when transporting products that are packaged with plastics.
  • Great versatility: plastic packaging has many forms that can vary from flexible and adaptable to sturdy and resilient types like plastic containers.

The Plastic Con’s

Plastics may provide a number of easy advantages for businesses as mentioned above, but this does not mean the cons should be disregarded.

Plastic production is around 381 million tons and 5 trillion or more pieces of plastic are polluting the waters around the world. However, more consumers are demanding recycled content in plastic which is driving accelerated progress in recycling plastics. Some additional cons include:

  • Large carbon footprint of production: the production of plastic also releases excessive amounts of carbon dioxide into the atmosphere which pollutes the environment.
  • Not properly recyclable: although plastic can be recycled, it has been reported that over 91% of existing plastic in the world has never been recycled.
  • Long lasting: as mentioned in the pro’s, it can take thousands of years to fully degrade, which is harmful to the environment when it does not end up in the recycling scheme.
  • Pollutes the environment: plastic pollutes the oceans and land, and animals can also choke on this material. Over a long period of time, sunlight breaks the plastic molecules which then poisons the soil, affecting the fertility of the land. When plastic does eventually break down, it can still leave microplastic remains too which is also equally bad for the environment.


If for your company the pro’s outweigh the con’s, then it might be an option to consider bioplastics. Bioplastics are made from biodegradable sources such as vegetables, rice, and other organic and plant-based compounds.

Similar to other plastics, bioplastics are not currently recyclable, but they do break down much quicker than regular plastics, provided they are properly composted at in-home compost heaps or in extensive industrial compost facilities.

Bioplastics are usually much more efficient and eco-friendly than normal plastics and help contribute to the reducing of pollution.

At Swiftpak, we would recommend trying our polylactic acid (PLA) packaging as it is made from the renewable source, cornstarch, and so decomposes well in the presence of acids. PLA can be used for grocery bags, food packaging, thermal insulation as well as for medical applications.

Paper and Cardboard

Both Paper and cardboard are seen by many brands as the quick solution to help them achieve their plastic reduction targets. Due to the explosive growth in e-commerce last year amongst other factors like Brexit and the pandemic, we are currently experiencing cardboard shortages as the demand for corrugated cardboard has surpassed the capacity of paper mills. It has even been named ‘the hunt for beige gold’. If this does not show you the popularity of cardboard, then what will?  

Many businesses are switching to paper because it is generally more environmentally friendly, as it does not pose such a threat to the environment if any should find its way into the ocean and waterways. Not only that, but there is a £200 a tonne tax coming into force in 2022 on any plastic packaging containing less than 30% recycled content, which further pushes businesses to reduce the amount of plastic they use.

The Paper and Cardboard Pro's

So, is paper more sustainable than plastic? The use of cardboard most definitely has its pros over the plastic alternative. Some of these include:

  • Recyclable: Cardboard is sourced from renewable wood pulp (processed into kraft paper) or recycled cardboard material. This means it has a high recycling rate of 85.8 in Europe, whereas plastic is mostly sent to landfill.
  • Sustainable: Cardboard has a clear sustainability benefit over plastic as it is biodegradable and breaks down much quicker.
  • Reusable: One of the greatest advantages is that cardboard boxes can be used again, and with the corners of the boxes being flexible, they can be collapsed when not in use.
  • Printing and design: Cardboard can be printed on easily making it perfect for marketing, branding, and promotional purposes.
  • Cost savings: Buying cardboard in bulk can save your business good deals of money due to their reusability.
  • Extended storage: As long as it is protected from water, cardboard can be stored for long periods of time.

At Swiftpak, we have a range of corrugated cartons that you can use instead of plastic. Corrugated cardboard boxes have many advantages that include being entirely recyclable making them more environmentally friendly than most plastics, whilst also being tear-resistant and highly affordable compared to other alternatives.

The Paper and Cardboard Con’s

Although many companies are making the switch from plastic to paper products such as cardboard, it is important to recognise that cardboard also has its own environmental issues.

  • Less durable: Cardboard is much less durable than plastic and can be susceptible to mould, fire, and water damages due to weather.
  • Stacking difficulties: Cardboard is not able to hold as much weight as plastic and so cannot be stacked as easily without breakage.
  • Moisture damage: Cardboard is not the best for weatherproofing as water and other types of liquid seep into the box and damage the contents inside.
  • Recycling rate: Paper cannot be recycled infinitely, it is said it can only be recycled 5-7 times before the fibres become too short.
  • Energy used during production: Boustead Consulting & Associates study revealed manufacturing 1,000 paper bags requires 3.4 times more energy than traditional plastic.
  • Bigger footprint during transportation: As plastic is lighter and thinner than cardboard alternatives, the logistics footprint of paper-based material is higher.
  • Global deforestation: Paper is made from trees, which is a renewable source. However, check if your cardboard or paper is FSC certified as you don’t want to add to global deforestation. At Swiftpak, we make it easy for our customers to re-plant the trees they have used.

Paper Void Fill

Paper void fill is great solution if you are looking to minimise the amount of plastic you use. It is a good alternative to bubble wrap as it is eco-friendly, recyclable, and re-usable. This void fill is also much more affordable and available on the market.

Paper void fill helps to protect your items during transit in a similar way to foam chips by filling up the remaining space, providing products with protective cushioning they need. 

Cardboard vs Plastic from Swiftpak

At the end of the day, it all depends on what you are shipping and how heavy the content is. Cardboard boxes can be a great cost-effective solution as they can be re-used. They are also generally better for the environment than the plastic alternative. However, as discussed stacking difficulties may occur, particularly if the box cannot handle the weight of the content. It also can be susceptible to liquid damages, with water much more likely to seep into the box and damage the contents.

A way around this is that you could try to switch to a bioplastic solution. Even though they are not yet recyclable, bioplastics do break down much better than regular plastics when properly composted, making them much more eco-friendly. All in all, there is no one size fits all and one needs to look at each company’s needs individually to decide what the best way forward is.
