- How are the tag and string attached to the tea bag?
- The tag and string are attached to the tea bag by heat sealing. All materials are fused together without the use of adhesives or similar agents. The filter, string, and tag are all made from safe materials that comply with applicable food contact regulations.
- Can a tea filter be used to brew coffee?
- Yes, coffee can be brewed using a tea filter. However, fine coffee particles may pass through the filter. For better filtration, we recommend using COFFEE MIRACLON.
- What are the advantages of tetrahedral (pyramid-shaped) bags?
- The spacious interior allows tea leaves to expand freely, helping to maximize flavor extraction.
- Are the tag and string used with SOILON tea bags also biodegradable?
- The tag laminate and string used with SOILON tea bags contain the same plant-derived PLA as the filter material. The tags, filter, and string are all biodegradable.
- Can tea bags be filled by hand?
- We also offer filters designed for hand filling. Please contact us for more information.
- Do you offer custom-printed tags?
- Yes. We also offer tea bags with custom-printed tags. Please contact us for more information.
- Are adhesives used to attach the hooks to the filters on drip bags?
- The hooks and filter material of our drip bags are joined by heat sealing, so no adhesives are used. Both the hooks and filter material are made from materials that comply with applicable food contact regulations.
- Do you offer a tea or stock bag that features a tag or string?
- Yes, for selected products. Please contact us for available materials and specifications.
- Can pre-made bags be formed into tetrahedral (pyramid-shaped) bags?
- Yes. Depending on how the opening is sealed, pre-made bags can be formed into tetrahedral (pyramid-shaped) bags.
- What is the difference between woven mesh filters and nonwoven fabric filters?
- Woven mesh filters have uniform openings and provide excellent extraction performance. In contrast, nonwoven fabric filters are suitable for packing fine powdered materials and help reduce leakage of fine particles.
- Do you have any woven mesh filters that can be heat-sealed?
- Our TEAROAD SHARP 5100 is compatible with heat sealing.
- How long does SOILON take to biodegrade?
- The rate of biodegradation varies depending on environmental conditions such as temperature, moisture, pH, and the type and number of microorganisms present. SOILON has been certified by TÜV AUSTRIA (OK compost INDUSTRIAL), DIN CERTCO, and BPI, and has met certification requirements for biodegradation within 180 days under controlled industrial composting conditions.
- Why are three types of woven mesh filters -- SOILON, SHARP, and TEAROAD -- available?
- The three products are made from different raw materials, and their suitability for ultrasonic sealing may vary slightly depending on the equipment and processing conditions. SOILON is also biodegradable, making it an environmentally friendly option.
- Are your nonwoven filters bleached?
- The white color of our nonwoven filters comes from the materials themselves. No bleaching process is used.
- What are the features of COFFEE MIRACLON?
- COFFEE MIRACLON boasts six times the fiber density of paper filters, helping to trap fine coffee powder and excess oils more effectively than conventional paper and nonwoven fabric filters.
- Are your paper filters bleached?
- Our paper filters are made using ECF (Elemental Chlorine-Free) bleached pulp. This bleaching process does not use chlorine gas and helps reduce the amount of absorbable organic chlorinated compounds in factory wastewater. We also offer non-chlorinated, unbleached paper filters in our WTF series.
- Do you offer tea bag filling services?
- We manufacture and sell filter materials only. We do not provide tea bag filling services.
- How much do your filters cost?
- Pricing varies depending on the filter material, size, and order quantity. Please contact us for a quotation.
- What forms are your filters available in?
-
Most of our filters are supplied in roll form.
