What is the Most Eco-Friendly Food Packaging? | Explore Eco-Friendly Solutions

In the modern food industry, eco-friendly food packaging has become a key focus of attention for both consumers and brands worldwide.

So, what are the materials that make up the food packaging on the market? Are they environmentally friendly? After use and how to deal with it? Today, join Упаковка Zhongjia to learn more about the best solutions for eco-friendly food packaging.

Food Packaging Bag Structure Disassembly

We start from a common pouch structure, which can usually be divided into the following four parts:

• Printing Layer
• Ink
• Glue
• Inner Material

Printing Layer: Choosing the Most Environmentally Friendly Materials

Common printing materials on the market include PET, NY, BOPP, and so on. Among them, BOPP is the ideal choice for eco-friendly flexible packaging:

• PET has high strength and good printing performance, but it does not have heat sealing performance, cannot be recycled separately, has a decomposition cycle of more than 200 years, and is extremely polluting to the environment.
• BOPP is a biodegradable, recyclable material; its essence is PP plastic, which can be recycled, hot extrusion granulation, and other ways to reuse, with good recycling value, is the custom eco-friendly flexible packaging factory recommended materials.

Ink: Water-based Ink is the Choice for Green Printing.

Three types of inks are commonly used in packaging printing: ink, UV ink, and water-based ink.

Traditional Ink:

It contains a lot of toxic solvents and releases VOC (Volatile Organic Compounds), which not only pollute the air but may also remain in the packaging, posing a threat to food safety.

UV Ink

Although it does not use solvents, the UV curing process generates ozone, which poses a certain environmental risk.

Water-base Ink:

The most environmentally friendly choice only needs to add food-grade alcohol, non-toxic, non-polluting, and biodegradable, but higher requirements for the printing process, mastering the technology of eco-friendly flexible packaging manufacturing is relatively small.

Glue: Solvent-free Glue is More Environmentally Friendly

Glue is mainly divided into:

Solvent-based Adhesive: Containing solvents and releasing harmful gases during production.
Solvent-free adhesive (Solvent-free Adhesive): does not contain volatile organic compounds, is non-flammable, environmentally safe, making become the first choice for green packaging.

Inner Layer Material: Selection of Recyclable PP Structure

In the inner layer material, the unified use of recyclable plastics such as CPP or BOPE with the printing layer is the key to environmental protection. They have good heat sealing performance and can realize a single material structure, which is conducive to later recycling.

Two Ideal Recommended Structures for Eco-friendly Food Packaging Bags

Combining the above elements, the following are the two most representative environmentally friendly structures in the market today:

✅ Structure I: BOPP + ink + solvent-free glue + CPP

• Printing layer: BOPP
• Ink: Чернила на водной основе
• Glue: Solvent-free adhesive
• Inner layer: CPP

Advantages: Strong overall environmental performance, recyclable, high food safety level, suitable for most food packaging products.

✅ Structure 2: BOPE + Ink + Solvent-free adhesive (or lamination) + BOPE

• Printing layer & inner layer: BOPE (single material structure)

Advantage: Extremely recyclable, suitable for some export products that require recyclable certification.
Disadvantages: Limited appearance due to poor printing suitability, low printing precision, only applicable to specific customer groups.
