CHINAPLAS 2026 Preview: How High-Barrier Packaging Films Help Food Brands Meet Carbon and Plastic Reduction Goals
In March 2026, it has been two years since China introduced new regulations for prepared foods, clearly stating that no preservatives are allowed during production. This policy has effectively shifted the responsibility for extending shelf life from formulation to packaging.
Since then, food manufacturers have been facing a practical question: how to maintain product freshness without preservatives while also reducing packaging material and improving recyclability.
This shift is bringing high-barrier packaging films into sharper focus. As sustainability and efficiency become central to industry development, the role of packaging is evolving from a supporting function to a core value driver.
The upcoming CHINAPLAS 2026, held from April 21–24 at the National Exhibition and Convention Center (Shanghai), will showcase the latest innovations in plastics and rubber across more than 390,000 square meters. Among the key highlights, high-barrier packaging technologies are expected to draw strong attention from the food industry.
So, how can high-barrier packaging films help companies address both carbon reduction (“dual carbon”) and plastic reduction targets?
- A Smarter Approach: Reducing Material Without Compromising Performance
1.1 What Defines High-Barrier Materials?
The main function of food packaging is to protect products from oxygen, moisture, and external contamination. Traditionally, improving barrier performance meant adding thickness or extra layers—an approach that conflicts with plastic reduction goals.
High-barrier materials offer a more efficient solution: better protection with less material.
In general, materials with an oxygen transmission rate below 10 cm³/(m²·24h·atm) are classified as high-barrier. The most widely used types include PVDC, EVOH, and PAN, each suited to different conditions.
1.2 Why PVDC Performs Better in Humid Conditions
One key difference lies in how materials respond to moisture.
EVOH delivers excellent oxygen barrier performance in dry environments. However, its molecular structure contains hydrophilic groups, which makes it sensitive to humidity. In high-moisture conditions, its barrier performance can decrease.
PVDC film, on the other hand, maintains stable oxygen and moisture barrier performance regardless of humidity levels. This makes it particularly suitable for packaging applications such as meat, ready meals, and dairy products, where moisture exposure is unavoidable.
In practical applications, PVDC-based films can achieve high barrier performance with very thin layers. For example, a 2–3 μm PVDC layer can deliver protection comparable to much thicker conventional materials.
This enables material reduction without sacrificing shelf life, supporting both sustainability and product quality.
1.3 New Developments in Bio-Based Barrier Materials
Bio-based materials are also gaining traction. A 2025 report by Wankai New Materials and Leaf Biotech highlights that PEF (polyethylene furanoate) offers:
Around 10 times the oxygen barrier performance of PET
6–10 times better CO₂ barrier properties
PEF has already been approved for food contact applications, making it a promising option for lightweight and sustainable packaging design.
The combination of high performance and reduced material usage is becoming a key pathway toward meeting plastic reduction goals.
- Lower Carbon Impact Across the Supply Chain
2.1 Reducing Food Waste Means Reducing Emissions
Carbon reduction is not just about packaging materials—it also involves the entire lifecycle of food products.
According to the Food and Agriculture Organization, roughly one-third of global food production is lost or wasted each year. This represents a significant amount of embedded carbon emissions from farming, processing, and transportation.
High-barrier packaging helps address this issue by extending shelf life and reducing spoilage, which in turn reduces the overall carbon footprint.
2.2 Example: Meat Packaging Applications
In meat packaging, high-barrier films such as PVDC composites can extend shelf life from 2–3 weeks to several weeks or even months, depending on conditions.
This brings multiple operational benefits:
Reduced reliance on energy-intensive cold chain logistics
Lower product losses in retail due to expiration
Reduced household food waste after purchase
These improvements contribute directly to lower emissions across the value chain.
- Cost Efficiency: Looking Beyond Material Price
3.1 Lower Return Rates Through Longer Shelf Life
Although high-barrier materials may have a higher upfront cost, they can reduce total operational costs.
Longer shelf life means fewer expired products and lower return rates. For large food companies, even a small reduction in returns can significantly improve profitability.
Companies such as WH Group， have demonstrated how high-barrier packaging can support consistent product quality and reduce losses.
3.2 Material Savings Through Down-Gauging
High-barrier materials enable thinner packaging designs without compromising performance.
For example, PEF can achieve similar barrier properties at significantly reduced thickness compared to PET. While the cost per kilogram may be higher, the overall material usage is lower, helping control long-term costs.
3.3 Preparing for Future Regulations
Sustainability regulations are becoming stricter worldwide. Policies such as the EU’s Packaging and Packaging Waste Regulation (PPWR) require higher levels of recyclability and recycled content.
High-barrier packaging designed with recycling in mind can help companies:
Meet regulatory requirements
Reduce compliance risks
Strengthen their sustainability positioning
Early adoption can provide a clear competitive advantage.
- FAQ: Key Questions About High-Barrier Packaging
Q1: How to choose between PVDC and EVOH?
A: The choice depends on the application:
EVOH: Best for dry environments and dry food products
PVDC: More suitable for high-humidity conditions such as meat and ready meals
In many cases, multilayer structures combine both materials to optimize performance.
Q2: Is high-barrier packaging worth the cost?
A: When evaluated across the full supply chain, the benefits often outweigh the initial cost:
Longer shelf life reduces waste and returns
Thinner materials reduce total usage
Improved compliance lowers regulatory risks
Overall, it offers strong cost-performance value.
Q3: What to watch at CHINAPLAS 2026?
A: Key trends include:
Mono-material high-barrier solutions from LG Chem
Bio-based materials such as PEF
Advanced composites from Covestro and Kingfa Sci. & Tech.
Recycling innovations from BASF and Borealis
Industry forums held during the exhibition will also provide insights into future packaging trends.
Conclusion
For food companies, high-barrier packaging is no longer just about preservation—it is a practical solution for reducing emissions, minimizing waste, and meeting sustainability targets.
For packaging suppliers, events like CHINAPLAS 2026 provide an opportunity to showcase solutions that deliver less material, reliable performance, and clear recycling pathways.
As the industry evolves, the ability to balance performance, sustainability, and compliance will define long-term competitiveness in food packaging.
