Paper or plastic: starting from the essence of the product
The question is not about which materials are more beautiful, but what your product needs to be protected from.
Choosing plastic (or plastic film) when the product needs to block moisture, gas, oil, or stay fresh. Choose paper when the product is stable and you prioritize a handcrafted, premium, easily recyclable feel. Many good packaging options combine both: paper for the exterior feel, plastic film for internal protection.
- the product is moist with oil and easily absorbs moisture, requiring a long shelf life
- sales through channels that need moisture protection for long-distance transport in humid climates
- combine outer paper box and inner film bag for protection
- choose uncoated paper for products that absorb moisture and lose fragrance
- Choose plastic for products that don't require barriers.
Paper seems like the obvious answer: beautiful, natural, easy to print, easy to tell a brand story. But if your product absorbs moisture, has a lot of oil, or needs a long shelf life, uncoated paper will let the product spoil before the customer even opens it. The right question is not "paper or plastic" but "what does my product need protection from, and which material can do that most authentically?"
Start with protection needs first, choose materials later.
All material decisions should start with a short list: what is your product sensitive to? If it’s moisture, the packaging needs to barrier moisture. If it’s oil, it needs an oil-resistant film. If the fragrance is volatile or easily absorbs foreign odors, it needs a gas barrier. Plain paper cannot achieve these functions unless coated or laminated with a functional layer. Conversely, if the product is dry, stable, and has a quick turnover, paper is usually sufficient and even better than plastic in terms of brand feel.
Vietnam's hot and humid climate is a real constraint. Products that can withstand air-conditioned storage may fail in trucks or on supermarket shelves without temperature control. The distance of the distribution channel and the duration of inventory both affect the level of barriers needed.
When is plastic mandatory
There are cases where there are no practical alternatives other than plastic or plastic film:
- Moist or liquid products, creams, pastes: absorbent and dissolving paper.
- Products high in grease, like fried snacks, roasted nuts, and oil-based seasonings: uncoated paper absorbs oil, compromising packaging integrity and visual appeal.
- Products with fragrances that need to be retained or that easily absorb strange odors like coffee, tea, ground spices: require a gas barrier film, usually a multi-layer plastic structure or metallized film.
- Long shelf life, several months: high barriers cannot come from single-layer paper.
- Long-distance shipping, warehouses without humidity control: proactive protection is needed, not just relying on ideal conditions.
When paper is the right choice
Paper excels when the product does not impose high barrier requirements:
- Dry, stable products like sugar, coarse salt, and some types of dry snacks sell and consume quickly.
- Gift boxes, secondary packaging (the outermost layer) where the inner layer has taken care of protection.
- Products positioned as handcrafted, natural, premium, where the tactile experience is part of the brand experience.
- A market where recyclability is a truly verified message, not just a sticker.
Plastic or plastic film: Active barriers, mandatory when products are sensitive or have a long shelf life. More difficult to recycle, and honest communication is needed if the brand discusses sustainability.
Combination (outer paper, inner film): The most common approach in practice. Paper conveys the feel and brand story, while the film protects the product. Note: composite structures are often harder to recycle than individual layers.
The common error when selecting materials
- Choosing paper for its beauty and "sustainability" can lead to products that absorb moisture, mold, or lose fragrance before the expiration date.
- Thinking that paper is always better recycled than plastic, forgetting that paper coated or laminated is very difficult to recycle in most current collection systems.
- Choosing plastic for products that do not require barriers, missing the opportunity to build a handcrafted feel and premium positioning with paper.
- Deciding based on competitors' templates or prices, without considering what your product needs to protect and under what conditions.
Packaging materials are not an aesthetic choice. They are a technical and brand decision at the same time. Getting either one wrong will compromise the other.
Practical experience, Sinh Vũ Studio
Sinh Vũ's viewpoint
When researching packaging for clients, Sinh Vũ starts by examining the product: is it sensitive to moisture, does it contain oil, does the fragrance need to be preserved, what conditions does the sales channel impose? From there, we balance brand feel with practical protection needs.
A common approach in projects implemented by Sinh Vũ is an outer paper box that conveys a premium feel, combined with an inner plastic bag or film to ensure freshness. This method does not force a single material to fulfill all roles and helps you communicate more honestly about both the handcrafted feel and food protection requirements.
What Sinh Vũ avoids most is choosing materials from existing samples and then adjusting them to fit the product. The correct process is the opposite: the constraints of the product and distribution channel determine the materials, not the other way around.

Frequently asked questions
Is coated paper better than pure plastic?
Coated or laminated paper combines the surface feel of paper with the moisture barrier of plastic, but this structure is often harder to recycle than pure paper. You should consider this as an intermediate option, not the best solution in every aspect. It is suitable when you need both: a premium feel and adequate protection.
Does a dry product like a cookie need plastic?
It depends on the shelf life and shipping conditions. Crispy cookies are very sensitive to moisture; if sold far away or stored for long, packaging without moisture barriers will cause the product to soften and lose quality before the expiration date. If sold directly on-site and rotated quickly, paper may suffice. But for wide distribution, moisture barriers are needed, whether inside or outside.
I want to position the brand as sustainable. Can I use plastic?
Yes, if you choose plastic because the product genuinely needs it and communicate honestly about that reason. Sustainable positioning collapses when packaging promises but the product fails early due to wrong material choices. It’s better to use plastic where necessary, paper where sufficient, and clearly explain to customers rather than avoiding the topic.
