The Next Generation of Coffee Packaging—TiMELESS® Valveless Technology
TiMELESS® is a patented packaging innovation that eliminates plastic valves, reduces costs, and keeps coffee beans in good condition. Designed to replace traditional one-way valves used in coffee bags, TiMELESS® enables brands to simplify production while making a measurable impact on sustainability.
World of Coffee 2026
NAGASE & Co. is debuting TiMELESS® at World of Coffee 2026, showcasing a patented, valveless degassing technology for coffee packaging.
Doutor Coffee
Doutor Coffee has adopted eco-friendly paper packaging, which uses the valve-free TiMELESS® technology, for its Hatsugama coffee set. This packaging preserves freshness and reduces environmental impact by combining biodegradable materials with gas-control features.
PostCoffee
PostCoffee, Japan’s largest coffee subscription service, has adopted the eco-friendly TiMELESS® packaging for all its coffee bean deliveries. This technology uses microchannels to release gas, helping preserve freshness while reducing environmental impact and packaging costs.
Sarutahiko Coffee
Sarutahiko Coffee is switching all its coffee bean bags to use TiMELESS® packaging, a gas-control technology that reduces plastic by eliminating the need for plastic valves. This eco-friendly move supports the company’s sustainability goals and marks the first nationwide in-store rollout of the technology in Japan.
What is TiMELESS® ?
TiMELESS® redefines coffee packaging with built-in gas-release technology that eliminates the need for plastic valves. This innovative approach maintains coffee freshness, streamline production, and helps cut costs while reducing their environmental footprint.
The result:
- A more cost-efficient, eco-friendly, and streamlined production process.
- Coffee that maintains freshness and aroma from roastery to cup.
- A packaging solution that supports the global shift toward sustainable materials
TiMELESS®'s unique microscopic flow channels expel CO2 gas generated from coffee beans while at the same time effectively preventing the intrusion of oxygen from the atmosphere.
How It Works
Valve-Free Degassing Technology
Using micro-sealing technology, TiMELESS® forms ultra-fine flow channels within the seal of the packaging film. These channels allow CO2 released by freshly roasted beans to escape, while blocking oxygen from entering. This simple yet powerful structure maintains freshness—without any plastic valve.

PostCoffee — The Coffee You're Meant to Find is Waiting for You.
As specialty coffee continues to grow worldwide, PostCoffee, one of the largest online coffee companies in Japan, has built a distinctive experience for discovering your perfect cup — both online and in-store.
Key Advantages of TiMELESS®
Flow channels are ultrasonically formed directly into film or paper packaging—no valve parts, no manual installation. Coffee can be packed immediately after roasting, eliminating the need for aging or degassing time. That means fewer steps, fewer materials, and lower labor costs.

US alone uses approximately 1.8 billion plastic degassing valves per year (as of 2025). TiMELESS® eliminates these entirely. Because it can be produced from a single recyclable material, it supports the shift toward mono-material packaging, promotes resource recovery, and reduces overall environmental impact.

TiMELESS® Packaging Solutions to Fit Your Business
Whether you’re a small roaster or a large-scale producer, TiMELESS® offers flexible adoption paths:
For packaging manufacturers
TiMELESS Units for Converters
Designed for packaging manufacturers and converters looking to expand their product portfolios. The TiMELESS® processing unit can be seamlessly integrated into your existing pouch-making , enabling you to supply high-performance, gas-releasing packaging directly to your own brand clients.
For coffee customers
Premade bags for small start
Perfect for boutique roasters, pilot runs, or growing brands. Get to market quickly using our pre-made TiMELESS® pouches, eliminating the need for specialized inline packaging machinery. We offer flexible options to fit your stage of growth—from standard ready-to-use bags in quantities as low as 100 units, to fully customized designs (shape, size, and print) starting from approximately 20,000 bags.
VFFS machine for mass production
Engineered for high-volume producers demanding maximum efficiency. For mass production, you can operate using a vertical form-fill-seal (VFFS) machine integrated with the TiMELESS® unit.
Challenges in Coffee Packaging Today
Conventional degassing valves add cost at every step—from material procurement to installation. As prices rise and production margins tighten, cutting this extra component offers brands a smart way to lower expenses.
When gas isn’t released efficiently, bags can expand or tear during transport or on retail shelves. Beyond logistics issues, consumers often see bloated bags as a sign of poor quality, which can harm a brand’s image.
Most coffee bags combine multiple layers of plastic and foil, making them impossible to recycle. The addition of single-use plastic valves only adds to the problem. As sustainability expectations grow, brands are under pressure to reduce packaging waste and move toward circular, recyclable materials.
FAQs
Most heat-sealable films and papers can be used. If you have specific substrates in mind, our team can test and verify compatibility.
Some existing VFFS machines can be modified, though we generally recommend using equipment designed for TiMELESS® for best results.
TiMELESS® removes the need for plastic valves, reducing plastic consumption and improving recyclability—key steps toward sustainable packaging.
Beyond Coffee
TiMELESS® micro-sealing technology is also suitable for:
Fresh produce packaging
to control gas exchange and moisture retention
Frozen foods packaging
to improve freshness and eliminate unnecessary materials
The Story Behind TiMELESS®
The Nagase Group developed TiMELESS® with a mission to reduce environmental impact and preserve resources for the future. By replacing plastic valves with an integrated degassing channel, TiMELESS® lowers costs and supports a circular economy—benefiting both businesses and the planet.
