Bagasse Tableware Glossary
This glossary defines the 15 terms that appear in Jirun's specification tables, grease barrier comparison and test reports, from bagasse and moulded fibre to PFAS, KIT, Cobb and 40HQ. Each definition is one to three sentences and has its own anchor.
01Material and process
Material and process
- Bagasse
- The fibre left after sugarcane is crushed for juice. It is pulped and moulded into tableware; on this site it always means sugarcane bagasse. Jirun's tableware uses a blend of 75% bagasse and 25% bamboo pulp.
- Moulded fibre
- Products formed by depositing a fibre slurry on a mould and drying it into shape. Bagasse tableware is one type of moulded fibre. The American spelling is "molded fiber".
- Wet-press thermoforming
- The wet fibre preform is pressed between heated moulds, which dries and shapes it in one step and gives smooth surfaces on both sides. It is the process Jirun uses.
- Dry-press
- A moulded-fibre process in which the formed piece is dried first and pressed afterwards. Surfaces are usually rougher than wet-press pieces.
- Natural / unbleached
- Pulp that has not been bleached, which gives the light brown colour of the fibre. The white version is made from bleached pulp; Jirun's white pulp is bleached without chlorine-based bleaching agents (factory statement).
02Grease barrier and testing
Grease barrier and testing
- Grease barrier
- The treatment that stops oil and water soaking through the fibre. Jirun makes a fluorine-free wax-emulsion grade and a fluorinated grade; laminated or spray-coated grades, which contain plastic, are made elsewhere.
- Fluorochemical
- A fluorine-containing additive used as an oil and water repellent in moulded fibre. Fluorochemical repellents are PFAS.
- PFAS
- Per- and polyfluoroalkyl substances: a large group of persistent fluorinated chemicals, restricted in food-contact packaging in the EU.
- Total fluorine
- A measurement of all fluorine in a sample, commonly by combustion ion chromatography (CIC). It is used as a screen for PFAS, including polymeric PFAS that targeted tests do not list.
- PPWR
- The EU Packaging and Packaging Waste Regulation, Regulation (EU) 2025/40. Its Article 5 limits PFAS in food-contact packaging placed on the EU market from 12 August 2026.
- KIT test
- A grease-resistance test for paper and board (TAPPI T 559). Twelve numbered solutions of increasing aggressiveness are applied; the rating is the highest number that does not stain the surface.
- Cobb value
- The mass of water absorbed by a paper or board surface in a set time, in g/m² (ISO 535). A lower value means less water absorption.
03Packing and shipping
Packing and shipping
- Sleeve
- The inner pack: a stack of pieces wrapped together inside the carton. Jirun sleeves hold 10 to 100 pieces depending on the model.
- CBM
- Cubic metre (m³), the unit of carton and shipment volume. Carton CBM is length × width × height of the carton in metres.
- 20GP / 40HQ
- A 20-foot general-purpose container and a 40-foot high-cube container. Loading estimates on this site assume 28 m³ and 68 m³ of usable volume respectively.
