Key Benefits
- Transparent film lets consumers see the whole leaf or flower inside, building trust in tea quality
- Allows tea to fully expand and release flavor during brewing, improving taste and extraction
- Supports repeated brewing due to strong, durable material that resists tearing
- Ultrasonic sealing creates a seamless, tight seal without heat or adhesive
- No additional filter layer needed during bag making, simplifying the production process
- Tasteless and odorless material preserves the original aroma and flavor of the tea
Application Scenarios
- Tea producers packaging single-origin whole leaf tea for retail sale with visible quality
- Herbal and health tea brands needing transparent bags to show natural ingredients
- Contract packers running multiple blends where visual quality assurance is important
- Coffee roasters using the film for drip coffee hanging-ear bags with a clear view of the beans
Who It Is For
- Tea blenders moving from paper filter bags to transparent pyramid bags
- Brands that want consumers to see the quality of the tea inside the bag
- Producers using whole leaf, flower or root blends that need room to expand
- Packaging material distributors supplying film for automatic pyramid tea bag machines
Problems It Solves
- Paper filter bags restrict tea expansion and limit flavor release during brewing
- Opaque bags hide the quality of the tea, reducing consumer confidence
- Traditional filter bags require an extra filter layer, increasing material and labor cost
- Low-strength films tear during sealing or brewing, leading to product loss
- Non-transparent films prevent visual inspection of the tea, increasing risk of rejection
Technical Features

How It Compares
| Paper filter tea bag | Nylon film allows full tea expansion and repeated brewing, while paper restricts movement and degrades after one use |
|---|---|
| Non-woven filter film | Nylon offers higher clarity and transparency, while non-woven is opaque and less visually appealing |
| PET biodegradable film | Nylon has better heat resistance and durability for repeated brewing, while PET may soften under high temperature |
Use Guide
- 1Unroll the film carefully to avoid creases or damage before loading into the machine
- 2Ensure the film is aligned with the machine's guide rollers and sealing head
- 3Check that the film size matches the machine's set format (120x50, 140x58, or 160x65 mm)
- 4Run a test batch with 10 bags to verify seal integrity and bag formation
- 5Clean the film path and sealing head after each batch to prevent residue buildup
- 6Store unused film in a dry, cool place away from direct sunlight to prevent degradation
