Where to start with green materials
The question is not 'which material to choose', but 'which step to start with'.
Start by using fewer materials, not by switching to materials that sound greener. The correct order is to reduce volume first, then move to recyclable design, and finally to recycled or biodegradable materials. A green decision is only credible when based on the actual lifecycle of the packaging and the real collection infrastructure where you sell.
- packaging that reduces excess layers while still providing adequate protection
- has a stable source of recycled content.
- sustainable positioning wants to take real action, not just slogans
- jumping straight into biodegradable materials while skipping the reduction step
- the sales location lacks industrial fermentation infrastructure
When a business decides to "make greener packaging," the first step is often to find new materials: paper instead of plastic, biodegradable boxes instead of regular boxes. This is the wrong order of steps. Sinh Vũ sees this repeated in many projects: the brand spends budget on changing materials but the actual impact on the environment remains almost unchanged, and in some aspects, even worse.
The correct order to begin
The foundational principle in sustainable packaging design is: reduce first, recyclable second, special materials last. These three levels cannot be reversed.
- Reduce: Is the packaging using unnecessary layers? Can the internal space be minimized? Can the thickness be reduced while still providing adequate protection? This is a step that creates real impact and often saves costs.
- Recyclable design: Can the packaging be recycled in the actual recycling stream where you sell? This question is entirely different from asking, "Is this material theoretically recyclable?"
- Green materials: Only at this stage should we discuss PCR (post-consumer recycled) plastics, bioplastics, or uncoated paper-based materials. Even here, each option still needs to be verified under specific conditions.
A green decision is only credible when based on the actual lifecycle of the product and the real collection infrastructure at the point of sale, not on feelings about materials.

Factors to check before selecting materials
Before you sit down to choose materials, you need to answer four questions:
- How sensitive is the product inside to moisture, light, and oxygen? Poor protection leading to spoilage before the expiration date is a greater waste than the packaging.
- At the point of sale, where do buyers actually dispose of packaging after use? General trash, separate recycling, or return to a collection point?
- Does the recycling or composting infrastructure in that market handle the materials intended for use?
- What is the cost difference and the stable supply capability of that material in Vietnam?
There is no answer to these four questions; every material decision is a guess.
When to choose which direction
Prioritize reducing materials when the packaging is using excess layers, excess internal space, or the structure can be simplified without compromising protection. This is often the most suitable starting point for businesses in the early stages.
Prioritize using PCR recycled materials when you have reduced volume, a stable supply of PCR, and product contact standards allow it. Do not use PCR for food contact packaging unless testing has been confirmed.
Postpone biodegradable materials until it is confirmed that the sales location has industrial composting infrastructure or separate collection. If not, this material ends up in the landfill and does not provide any benefits compared to regular plastic.
Common errors
- Jumping straight into biodegradable materials while skipping the step of reducing volume increases costs without changing the actual impact.
- Switching to moisture-resistant coated paper and thinking it is greener than plastic. The coating often prevents the paper from entering the regular recycling stream.
- Choose weaker protective materials to look greener, leading to premature product failure. The overall environmental impact is worse than initially.
- Believing in the "eco-friendly" or "biodegradable" label on materials without asking what the specific degradation conditions are.
The viewpoint of Sinh Vũ
Sinh Vũ approaches green materials from the constraints of production and the challenge of protecting genuine products, not from slogans. When working at the stage of creating the die-cut mold and selecting materials, Sinh Vũ compares the need to protect the product with the actual printing and collection infrastructure in Vietnam. The first step is always to see how much the current packaging structure can be reduced and simplified before discussing special materials.
For projects requiring deeper research, Sinh Vũ's In-depth Package includes research on green materials such as recycled PCR plastic, bioplastics, and paper-based materials, set within the context of actual supply and printing conditions in Vietnam, not ideal conditions from foreign documents.

Frequently asked questions
Is paper always greener than plastic?
Not always the case. Coated paper or moisture-resistant paper is often harder to recycle than regular virgin plastic, as recycling plants must separate the layers before processing. Decisions should be based on actual life cycle assessments and recycling infrastructure at the point of sale, not on material perceptions.
Is biodegradable packaging suitable for the Vietnamese market?
It depends on the sales location. Most biodegradable materials require industrial composting conditions to decompose properly. If the sales area lacks the infrastructure for collection and composting, the materials will end up in landfills and decompose like regular plastic, possibly even slower. Sinh Vũ advises postponing the switch to this group of materials until the end infrastructure is confirmed.
What is PCR recycled plastic and can it be used in food packaging?
PCR is post-consumer recycled plastic. For food contact, PCR requires separate testing due to the inconsistent raw material compared to virgin plastic. In Vietnam, the supply of PCR that meets food contact standards is still limited, so you need to confirm with the supplier and check current regulations before proceeding with production.
