As the spring breeze warms up, all things come back to life. The annual birch sap collection season is approaching.

As your long-term partner, Qichen Packaging upgraded all collection bag products in 2026 in terms of materials and structure, and simultaneously launched a free traceability system - we are committed to providing you with full-process quality assurance.

1.Featured product:【Qinon II 】Airtight self-sealing collection bag

This is a classic product line that has been verified by the market and is trusted by the collection teams. In 2026, to adapt to different work intensity requirements, we divided it into "single-layer bag" and "double-layer bag", respectively,

a. 【Qinon II 】Single-layer bag - The best value choice, efficiency upgrade

•      Membrane upgrade: Fully equipped with " Qinon III" new food-grade membrane, the toughness and puncture resistance have improved by approximately 50% compared to previous products, and the transparency has further increased, making it easier to observe the liquid level.

•      Thickness increase: The single-side thickness has been upgraded from last year's 55 μm to 70 μm, and the total double-side thickness has reached 140 μm,  and the impact resistance and durability have been simultaneously improved.

•      Capacity optimization: The standard capacity has been upgraded from 8L to 10L, combined with the sealed self-sealing feature, it can effectively extend the single-time hanging bag time, reduce the frequency of changing bags, and significantly reduce the total cost of labor and consumables.

Application scenarios: Routine forest area operations, teams seeking high cost-effectiveness and collection efficiency.

b.【Qinon II 】Double-layer bag - Stronger upgrade, suitable for complex environments

•      Structural innovation: Adopt a 50μm (outer membrane) + 40μm (inner membrane) double-layer co-extrusion structure, the outer layer is anti-puncture and anti-tension, and the inner layer strengthens sealing and barrier performance.

•      Performance leap: The double-layer structure brings more excellent strength performance, especially suitable for complex terrain, dense shrubbery or long-distance transportation in harsh collection environments.

Application scenarios: Forest area environments with complex conditions, requiring higher bag strength for collection operations.

2. High-performance option:【Qinon III 】Aseptic collection bag

If you have an ultimate pursuit for the quality of birch sap, 【Qinon III 】 will be your exclusive choice.

•      Core features: Factory-ready to achieve sterile state, almost completely isolating air during collection, minimizing oxidation and microbial contamination, preserving the original flavor and active components of the sap.

•      Material upgrade simultaneously: Equipped with "Qinon III" high-performance membrane, ensuring strength and durability in addition to sterility.

•      Target positioning: For high-end brands, scientific research-level collection or customized projects with extreme requirements for raw material quality.

3. Storage and transportation accessories: Qinon Aseptic storage and transportation bag series

From the forest to the factory, high-quality birch sap need to be protected throughout the journey. We also provide a sterile storage and transportation bag specially developed for the birch sap industry, with an inner membrane using a food-grade special formula to ensure zero pollution during transportation.

•      Complete specifications: Available in 25L, 220L, and 1000L, suitable for all scenarios from temporary storage by the collection team to batch acquisition by the factory.

•      Aseptic guarantee: The same aseptic process as 【Qinon III 】 ensures stable quality of the sap during storage and transportation.

4. Free value-added service: Qinon birch sap traceability system

In 2026, we prepared a digital gift for all customers - the Qinon birch sap traceability system (mini program "Huazhiyuanzong").

This system adopts a "one bag one code " technical architecture， providing you with：

•      Traceability to the forest: Scanning the code can obtain key information such as the collection forest area, collection team, collection time, etc.

•      Traceability to the tree (optional)： Precisely bound to a single tree, creating a unique "tree coordinate" story for high-end raw materials. From now on, all customers who purchase the 【Qinon II】 or 【Qinon III】 collection bags can enjoy free access to the traceability system. We hope this service will help you provide downstream customers with verifiable proof of the source quality, allowing good raw materials to "speak for themselves".

Summary and Prospect

In 2026, Qichen Packaging will not only be an upgrade in product parameters, but also a clear reorganization of the product system and an extension of service value. We hope to offer a wider range of choices, more solid quality, and more transparent data, so that every customer can match according to their needs and ensure the quality of good raw materials from the source.

Currently, all products have started full-scale production preparation. If you need samples, consultation on cooperation, or to activate the traceability system, please contact your dedicated project manager or leave a message on the back end to get in touch with us.

As spring brings forth new growth, we meet in the forest.
