Will eco-friendly packaging and sustainable development become the mainstream trend in the future?

The Real Meaning of Eco-Friendly Packaging

Eco-friendly packaging is not as simple as switching to a different material. It is a systematic issue involving material selection, printing processes, and the entire transportation and recycling chain. Many brands print the word "eco-friendly" on their packaging without any data to back it up, which actually damages brand trust.

Truly eco-friendly packaging must answer three questions:

• Are the materials sourced sustainably? Are they recyclable? Are they biodegradable?
• Does the production process feature low VOC (Volatile Organic Compounds) emissions? Is it energy-efficient?
• Can consumers correctly sort and recycle it after use?

The Four Levels of Eco-Friendly Packaging

Level 1: Reduction

The most effective eco-friendly approach is not using new materials, but using less material. GB 23350-2021 "Restriction of Excessive Packaging for Commodities" sets mandatory requirements for food and cosmetics packaging:

• Packaging layers must not exceed 4 layers (mooncakes and rice dumplings must not exceed 3 layers).
• Packaging cost must not exceed 20% of the selling price.
• Excessive packaging volume relative to the necessary space is a violation.

For brands, reduction is both a compliance requirement and a cost-saving win-win. Eliminating one layer of lamination, one inner tray, or one unnecessary base can reduce costs by 10%-30%.

Level 2: Material Substitution

There are three mainstream approaches to material substitution:

1. Monomaterial design — Traditional composite packaging (such as PE + aluminum foil + paper) is difficult to recycle. Switching to a single PE or single paper structure can increase the recycling rate from 30% to 80%. However, barrier properties will decline, requiring a trade-off.
2. Recycled paper replacing virgin wood pulp — Recycled paper has a carbon footprint approximately 60% lower than virgin wood pulp, and is suitable for most folding cartons and corrugated boxes. Note that direct food contact scenarios must comply with GB 4806.8-2022 requirements.
3. Biodegradable materials — Bio-based materials such as PLA (polylactic acid) and PHA can be composted and degraded under specific conditions. It is necessary to clearly label the degradation conditions (such as industrial composting vs. home composting) and certification standards (EN 13432, ASTM D6400).

Level 3: Greener Processes

The focus of eco-friendly transformation in the printing process is ink and energy:

• Water-based ink replacing solvent-based ink — VOC emissions are reduced by more than 70%, but some special materials (such as synthetic paper face stock for self-adhesive labels) still require solvent-based ink to ensure adhesion.
• Energy issues with UV curing processes — UV curing consumes more energy than water-based ink drying, requiring an overall carbon footprint assessment.
• Digital printing reduces plate-making waste — Traditional offset printing generates trial print waste with every plate change, while digital printing has zero plate costs and significantly reduces waste rates.

Level 4: Recycling Convenience

Even if materials are recyclable, it is futile if consumers do not know how to sort them. The recycling symbols on packaging need to be clear and explicit:

• Mark recyclable categories in accordance with the GB/T 16716 series of standards.
• Avoid using misleading symbols (such as labeling ordinary plastic as "biodegradable").
• Simplify structures so that consumers can distinguish paper, plastic, metal, and glass at a glance.

Which Industries Face the Strictest Regulation

Based on customer inquiry frequency, the following industries face the greatest pressure regarding eco-friendly packaging:

1. Food and Beverage—GB 23350-2021 is mandatory, with regular spot checks conducted by local market supervision departments.
2. Cosmetics—Also subject to GB 23350-2021 regulation, with numerous cases of fines for excessive packaging.
3. Products Exported to the EU—Must comply with RoHS and REACH regulations, otherwise customs clearance will be blocked.
4. Electronic and Electrical Packaging—RoHS Directive restricts substances such as lead, mercury, cadmium, and hexavalent chromium.

Common Misconceptions About Eco-Friendly Packaging

After years of working on packaging projects, I have come across several recurring misconceptions:

• Myth 1: Eco-friendly = Expensive — In reality, this is not necessarily true. The price of recycled paper is close to that of virgin wood pulp; water-based inks have a slightly higher unit price, but the overall cost is actually lower. Biodegradable materials are currently somewhat expensive, but the price of PLA has been dropping by more than 10% every year.
• Myth 2: Kraft Paper = Eco-Friendly — Kraft paper is mistakenly considered eco-friendly because of its plain appearance, but it is still essentially made from wood pulp, and its carbon footprint is not necessarily lower than that of white cardboard. The advantage of kraft paper lies in its high recyclability.
• Myth 3: Reducing Plastic Means Being Eco-Friendly — Paper bags sometimes have a higher carbon footprint than plastic bags (for example, heavy-duty paper bags). A full Life Cycle Assessment (LCA) is required; it cannot be judged by intuition.
• Myth 4: Printing "Eco-Friendly" on the Packaging — This constitutes unsubstantiated advertising and, according to the Advertising Law, may be deemed misleading. Eco-friendly claims need to be supported by specific data or certifications.

Trend Outlook for the Next 3 Years

Will eco-friendly packaging become the mainstream? Looking from both the regulatory and consumer perspectives, the answer is yes. However, "mainstream" does not mean a "single option"; plastic, metal, and composite materials will still retain their place in specific scenarios. The future direction is to select the most suitable eco-friendly solution based on the scenario, rather than a one-size-fits-all approach.
