STiR coffee and tea magazine

STiR coffee and tea 47 Identifying opportunities and overcoming obstacles in the single-serve capsules industry AMI's Single-Serve Capsules conference is the forum to debate and evaluate the global trends, innovations, challenges and opportunities facing the industry through the value chain of plastic and metal capsules for capsule fillers and moulders, coffee roasters, material suppliers, technology and machinery suppliers. The program features presentations from key converters and compostability innovators in the capsule supply chain, including: • Martin Bussmann, Team Leader Biodegradable Packaging, BASF SE, Germany • Mike Walker, Global Key Account Manager, GATEWAY PLASTICS, United States • Derek Helmer, Chief Operating Officer, URTHPACT, United States • Frank Franciosi, Executive Director, US COMPOSTING COUNCIL, United States Single-Serve Capsules 2020 also provides numerous opportunities to network with key industry stakeholders and an exhibition area showcasing the latest innovations from a range of suppliers.

Historically, these were expensive muslin and silk and the bags aptly named. The combination of major shifts in tea growing and harvest- ing downgraded the quality of tea that could be cheaply bagged. That plus cost pressures shifted materials to food grade plastics and treated paper, with often heavy chemical treatment, The main- stream shapes evolved to the rectangular pillow and two-chamber folded bag. The basic method is to feed two sheets and add the 1-3 grams of tea between them, then seal and fold the resulting bag. DPH tea bag knotting machine Bio has moved from incremental improvements to fundamental transformation of materials, with abaca hemp, from a renewable source variety of Philippines banana tree, and newer uses of non-GMO cellulosic fibers all adding degrees of biodegrad- ability and compostability. Really advanced materials include electrospun hydrophilic polymeric nanofibers that have antibacterial and impurity filtration properties. The tea itself has been simplified until very recently to meet the limitations of mate- rial and shape. The key issue is how the barrier of the bag can be made porous enough for the water to interact with the tea. The flow is heavily influenced by the exposed surface area and space for the tea to unfold. Efforts to bag high quality loose leaf tea ran up against the limitations of both material and shape. By limiting the tea ingredients to broken up fannings and dust, the basic demands of fast brewing and adequate flavor were met. The legacy is the association of tea bags with inferior quality to loose leaf.
