Weighing Small Plastic Baggies: What's The Weight?

Plastic bags are lightweight and compact, weighing approximately 8.12g each. This is significantly less than the weight of a paper bag, which is estimated to weigh 55.2g when distributed in bulk. The weight of plastic bags has an impact on the carbon footprint of their extraction, manufacturing and transportation.

A single plastic bag weighs 8.12g

Despite the benefits of plastic bags, they do make up a large proportion of the litter in our seas. Switching to paper bags may reduce this waste, but it could also cause different environmental damages. Plastic bags are lightweight and compact, which is not the case for paper bags. This means that paper bags will produce a higher level of CO2 emissions when in distribution.

Paper bags weigh 55.2g

A single plastic bag weighs approximately 8.12g. In comparison, a paper bag of the same size weighs 55.2g. This means that paper bags are much heavier than plastic bags, which can have an impact on the environment. Paper bags have a higher carbon footprint than plastic bags due to their weight, as they produce more CO2 emissions during distribution. The extraction, manufacturing and transportation of paper bags result in a 305g carbon footprint per bag, compared to 12.8g for a standard HDPE plastic bag. This is a significant difference of 283.9%.

Despite the environmental concerns surrounding plastic bags, they have the lowest Global Warming Potential. Paper bags need to be used an unrealistic number of times to achieve the same GWP level as a plastic bag. Therefore, while paper bags may weigh more and have a higher carbon footprint, plastic bags contribute to the majority of litter in our oceans. Implementing plastic alternatives and changing to paper bags can cause different environmental damages.

Paper bags have a 305g carbon footprint

A single plastic bag weighs approximately 8.12g, compared to a paper bag of the same size, which weighs 55.2g. Paper bags weigh more than plastic bags, which means that when in distribution, they will produce a higher level of CO2 emissions. The extraction, manufacturing and transportation of paper bags has a 305g carbon footprint, per bag, compared to a standard HDPE bag which only causes 12.8g. This is a 283.9% difference. Despite what we are hearing in the media, the conventional plastic shopping bag has the lowest Global Warming Potential. Paper (and cotton bags) need to be used an unrealistic number of times to achieve the equivalent GWP level as a plastic bag.

The extraction, manufacturing and transportation of paper bags has a 305g carbon footprint per bag, compared to a standard HDPE bag, which has a carbon footprint of 12.8g. This is a 283.9% difference. Despite what we are hearing in the media, the conventional plastic shopping bag has the lowest Global Warming Potential. Paper (and cotton bags) need to be used an unrealistic number of times to achieve the equivalent GWP level as a plastic bag. Paper bags also produce a higher level of CO2 emissions due to their weight.

Paper bags need to be used many times to achieve the same GWP as plastic

A single plastic bag weighs approximately 8.12g, compared to the same size paper bag which is estimated to weigh 55.2g when distributed in bulk. This difference has a huge impact on the carbon footprint of the bag. The extraction, manufacturing and transportation of paper bags causes a 305g carbon footprint, per bag, compared to a standard HDPE bag which only causes 12.8g. This is a 283.9% difference. Paper bags need to be used an unrealistic number of times to achieve the same GWP level as a plastic bag.

Paper bags weigh much more than plastic, which means that when in distribution, they will produce a higher level of CO2 emissions. This is because more energy is needed to transport heavier items.
