Hopefully, this shift will lead to a cleaner, greener future. From food packaging to shipping supplies, even eco-friendly boxes are becoming more popular. They are made from earth-safe materials that don’t hurt the ecosystem. In this comprehensive guideline, you will walk through some amazing biodegradable packaging materials and how they help protect the planet. Continue to read ahead for more information!

A Detailed Breakdown of Biodegradable Packaging Materials

Here is a detailed breakdown of biodegradable packaging material options you need to know;

Corrugated Cardboard

Corrugated cardboard is made from paper, which comes from trees. It is completely natural and safe for the planet. When you throw away this packaging material, it breaks down with the passage of time. Rain, sun, and tiny bugs help it turn into soil. That means it doesn't stay on the ground forever like plastic. Not only this, but people can also recycle this material and use it again and again. This makes it an eco-friendly choice for packaging that keeps things while being kind to nature. As a business owner, investing in what is good for the planet is a smart move.

Corrugated Cardboard

  • Single Wall - About 1/8 inch (3 mm) thick
  • Double Wall - About 1/4inch (6 mm) thick
  • Triple Wall - About 3/8 inch (10 mm) thick
  • A Flute - Up to 1/4 inch (4.8 mm) thick
  • B Flute - Up to 1/8 inch (3.2 mm) thick
  • C Flute - Up to 11/64 inch (4.2 mm) thick
  • E Flute - Up to 1/16 inch (1.6 mm) thick
  • F Flute - Up to 1/32 inch (0.8 mm) thick

Recycled Paper

If you're looking for sustainable packaging, recycled paper is a great choice. It is made from old paper used by people, schools, and businesses. Instead of throwing this paper into the trash, it gets turned into new packaging. This helps stop pollution as well as saves water and energy. According to the Environmental Protection Agency (EPA), recycling one ton of paper can power a home for 6 months, save 7,000 gallons of water, and stop 60 pounds of air pollution. Choosing this kind of biodegradable packaging material helps the Earth and keeps waste out of landfills.

Recycled Paper

Thickness

  • Standard Paper - 0.05 mm to 1.5 mm
  • Lightweight Paper - 0.01 mm to 0.08 mm
  • Mediumweight Paper - 0.05 mm to 0.12 mm
  • Heavyweight Paper - 0.3 mm to 1.5 mm

Reusable Packaging Materials

Another biodegradable option for custom packaging boxes is reusable materials. They can even be reused for future shipments, such as bins, bags, boxes, or anything else that can be used again. It eliminates the need to use many new materials for creating the packaging. Reusable materials are not only strong but also last longer. This helps prevent your fragile things from breaking down during transit. These perks make reusable packaging materials an economical option for businesses and consumers alike. With so many options available, it can be hard to decide which material to pick, right? Well, going for reusable materials is a suitable option here.

Reusable Packaging Materials
