Tea packaging is more than just a container—it is the bridge between product quality, flavor, and brand experience. From protecting freshness and influencing brewing performance to communicating a brand’s sustainable values, every material choice—from the tea bag itself to the outer layer—shapes how a consumer perceives the tea.
For modern brands, packaging is a critical design decision to tell a story and define market positioning. As a leading food-grade non-woven fabric manufacturer, Yi Ting Non-woven Co., Ltd. has created this guide to help you understand every aspect of tea packaging—from exploring the main types of tea bags and comparing key materials to choosing outer packaging strategies that balance functionality, flavor, and sustainability.
What Is Tea Bag Material? The Heart of the Brew
The tea bag material determines how a tea brews, tastes, and even aligns with a brand’s sustainability goals. Below, we explore the main materials used in modern tea manufacturing.
1. Filter Paper — Traditional and Cost-Driven
Made from wood pulp and abaca (banana fiber), filter paper remains the most widely used material globally.
Advantages:
- Efficient water flow and quick brewing.
- Compatible with high-speed heat-sealing machines.
- Cost-effective choice for flat and double-chamber tea bags.
Limitations:
- Opaque appearance with limited visual appeal.
- Not ideal for premium loose-leaf teas that need more space to expand.
Best For:
- Mass-market, price-sensitive products.

2. Food-Grade Nonwoven Materials — Yi Ting’s Core Specialty
Modern tea brands are shifting toward food-grade nonwovens for their structural stability and consistent sealing. Yi Ting specializes in food-contact materials with several series:
- PLA Series: 100% plant-based and industrially compostable; the top choice for premium and sustainable brands.
- EP / ET Series: Global mainstream materials offering a balance of cost, filtration, and production stability.
- OHP Series (For Heat Sealing): Engineered for high-speed automatic heat-sealing production lines.
- PO3 Series (For Ultrasonic): Designed for ultrasonic sealing, ensuring clean edges without adhesives.
Key Advantages of Nonwoven Tea Bag Materials:
- Stable Flavor Release: Even fiber structure for smooth water flow and flavor release.
- Stable Sealing: High consistency in seal strength and reduced risk of bag breakage.
- Safe and Hygienic: Produced in cleanroom standards and compliant with food safety regulations.
- Customizable: Adjustable fiber composition, weight, and roll width for different packaging machines.
Among all, Yi Ting’s PLA Food-Grade Nonwoven stands out as the eco-friendly flagship option, combining silky transparency, heat resistance, and industrial compostability—ideal for premium pyramid tea bags and sustainable brands. Yi Ting’s food-grade nonwoven fabrics are trusted worldwide for their safety, consistency, and performance in tea and food packaging.
3. Nylon (Polyamide) and PET Mesh
Beyond non-woven fabrics, the market uses Nylon and PET meshes for pyramid bags. These offer high transparency and strength but come with significant environmental drawbacks.
Advantages:
- High tensile strength and stability for automated pyramid bag forming.
- Excellent transparency for premium product presentation.
- Smooth infusion and uniform pore size.
Limitations:
- Petroleum-based and not compostable.
- Less aligned with sustainable packaging trends.

Types of Tea Bags and How They Affect Flavor
The Pyramid Tea Bag
The pyramid bag is a relatively recent innovation that has revolutionized the premium tea market. This shape is what most people mean when they search for a “tea bag pouch.”
- Why it’s better: This design’s true genius is the three-dimensional space it creates. It allows whole tea leaves, large botanicals, and fruit pieces to fully unfurl and “dance” as they would in a loose-leaf infuser. This results in a much richer, more complex, and aromatic brew.
- Best Material: This shape is impossible with paper. It relies exclusively on a high-quality, flexible nonwoven mesh like PLA Food-Grade Non-Woven Fabric or Compostables.
The Standard String-and-Tag Bag (Pillow or Flat Bag)
This is the most common and recognizable tea bag in the world. It is typically a flat, rectangular, or “pillow” shaped bag made of paper, sealed on two or four sides.
- Why it’s used: Its primary advantage is cost and production speed. It is incredibly cheap to produce at high volume.
- The Drawback: The flat shape severely restricts infusion. To get any flavor, these bags must be filled with “fannings” or “dust”—tiny particles of tea leaves that infuse quickly but often result in a bitter, one-dimensional flavor.
The "Fuso" or Gusseted Tea Bag
This type of tea bag is a hybrid between a flat bag and a pyramid bag. It’s essentially a flat bag with a gusset (a fold) at the bottom, which allows it to expand slightly when filled with hot water.
- Why it’s used: It provides more room for infusion than a standard flat bag and can be used for better-quality broken-leaf teas. It’s often made of paper or a non-woven fabric, making it an affordable option for brands that want improved brewing performance without switching to pyramid bags.
- The Drawback: Although it expands more than a flat bag, the space is still limited compared to pyramid designs. It cannot fully accommodate whole-leaf teas, and its appearance is less visually appealing, making it more suitable for mid-range tea products rather than premium lines.
Tea Packaging Materials: Protecting Flavor, Freshness & Brand
Flexible Packaging (Pouches & Overwraps)
This category, which includes the other kind of “tea bag pouch,” is one of the fastest-growing in the industry due to its light weight and excellent barrier properties.
- Stand-Up Pouches (SUPs): The mainstream choice for retail packaging, offering convenience and visibility on shelves.
- Individual Sachets: Commonly used for high-end selections and the hotel industry, providing the best protection for each individual serving to lock in aroma.
Rigid Packaging
- Paperboard Boxes/Cartons: The most common packaging for mass-market teas. Since paperboard itself lacks a barrier, it must be paired with an inner bag to prevent the tea from going stale.
- Metal Tins (Caddies): The premium choice for high-end teas. They offer the highest level of protection against environmental factors but also come with the highest production cost.
- Glass Jars: A clean and aesthetic option, but they require a light-blocking design (such as dark-colored glass) because light exposure quickly degrades tea quality.
Making the Right Choice – A Supplier's Perspective
As a specialist manufacturer of core materials, we guide brands through these critical decisions every day. Selecting the ideal combination of tea bag material, bag structure, and outer packaging depends on three primary pillars:
1. Look at the Tea - Your Tea Type (Whole Leaf vs. Fannings)
- Whole Leaf: Use Pyramid Bags + PLA. This allows the leaves enough space to expand and release their full flavor.
- Tea Fannings/Dust: Use Paper Flat Tea Bags. This remains the most cost-effective choice for smaller tea particles.
2. Look at Brand Positioning - Your Brand Positioning (Premium vs. Value)
- High-End / Sustainable: PLA Non-Woven + High-Barrier Outer Packaging. This combination ensures premium quality and protects the tea’s integrity.
- Mid-Range: Standard Non-Woven. A balanced choice for durability and filtration performance.
- Value / Mass-Market: Filter Paper + Paper Box. Focuses on production efficiency and price competitiveness.
3. Look at Sustainability - Your Sustainability Goals
If a brand promotes itself as “Natural, Organic, or Eco-friendly” but continues to use petroleum-based plastic tea bags, the brand message becomes inconsistent and loses credibility.
The Clear Solution: By combining PLA Non-Woven Pyramid Bags + Compostable Outer Sachets + FSC-Certified Boxes, brands can establish a consistent and verifiable sustainable product line.
