Is Switching to Brown Paper Bags Really Better for the Environment? A Guide for NZ Retailers

As New Zealand businesses look for sustainable alternatives to plastic, brown paper bags are quickly becoming a popular choice in retail and hospitality. But what makes them a truly eco-friendly option? And what should NZ retailers know before making the switch?

This guide dives into the environmental benefits, how brown paper bags are made, and how you can choose the right type for your business needs—all while aligning with Aotearoa’s growing commitment to sustainability.

What Are Brown Paper Bags Made From?

Brown paper bags are typically made from kraft paper, a type of paper produced through the "kraft process". This method involves pulping wood chips using a mixture of water, heat, and chemicals to separate the cellulose fibres from lignin. The resulting paper is:

• Strong and tear-resistant

• Lightweight and recyclable

• Biodegradable and compostable

Kraft paper can be made from virgin pulp or recycled paper, and at Insinc Products, we offer some recycled options to help reduce demand on forests.

Why Are Brown Paper Bags Considered Eco-Friendly?

1. Biodegradability

Unlike plastic, brown paper bags break down naturally in the environment. Most decompose within weeks in composting conditions. Check to make sure they don't have a plastic or foil lining.

2. Renewable Resources

Paper is made from trees, a renewable resource. When sourced from responsibly managed forests (look for FSC or Environmental Choice NZ certifications), it supports sustainable land use.

3. Recyclability

Brown paper is widely accepted in recycling systems across New Zealand. It can often be reused multiple times before recycling.

4. Lower Emissions When Disposed

Even when incinerated, paper produces fewer toxic emissions than plastic.

The Manufacturing Process: A Closer Look

Kraft paper is made using less bleach and fewer additives than white paper, which contributes to:

• Lower energy consumption

• Fewer chemical pollutants

• Greater fibre retention (which makes the bag stronger)

Some bags also skip lamination or coating to remain fully compostable and suitable for council green bins or industrial composters.

Benefits for NZ Retailers

Switching to brown paper bags provides several practical and environmental advantages:

• Positive brand image – Consumers notice and appreciate businesses that use sustainable packaging.

• Compliance with NZ waste regulations – Local councils and national policies are pushing businesses to reduce plastic use.

• Versatile applications – Ideal for clothing shops, food outlets, takeaway services, and more.

• Cost-effective in bulk – Especially when buying from a local NZ supplier like Insinc Products.

Choosing the Right Brown Paper Bag

When selecting bags for your store, consider:

• Bag thickness and strength – Choose heavier grades for takeaway or bulky items.

• Handle options – Flat vs twisted handles based on carrying needs.

• Recycled content – Opt for high recycled fibre content for maximum eco value.

• Certifications – Look for FSC, ECNZ, Eco Choice Aotearoa or Toitū certification.

What About Grease or Liquid Resistance?

Some kraft paper bags can be lined with PLA (plant-based) coatings or come with grease-resistant finishes, still keeping them compostable. Insinc Products stocks a range suitable for food service and takeaway use.
