Coffee packaging requires careful attention to gas management and bag format because freshly roasted coffee emits CO₂ for days to weeks after roasting. Packaging without degassing provision will balloon and burst; packaging without adequate oxygen barrier will allow the coffee to stale. Standard coffee bag formats: block-bottom bag (also called flat-bottom or box-bottom bag) — a bag with four sealed vertical seals and a flat, rectangular base formed from the bottom gusset; the premium format for specialty coffee, stand-up on shelf; requires a specialist FFS block-bottom machine or premade bag filler. Side-gusset bag — a flat bag with two side gussets, giving a more rounded cross-section when filled; widely used for ground coffee in retail; produced on a VFFS machine with side-gusset attachment. Stand-up pouch (doypack) — a flat-bottom stand-up pouch with or without zipper; increasingly common for specialty coffee. Pillow bag — the simplest VFFS format; used for commodity coffee in price-sensitive markets. One-way degassing valve: freshly roasted whole bean or ground coffee releases CO₂. A one-way degassing valve (one-way coffee valve) is heat-welded into the bag, allowing CO₂ out but preventing O₂ from entering. Valve insertion is either pre-inserted into premade bags by the bag manufacturer, or inserted inline by a valve-insertion station on the coffee packing machine. Nitrogen flushing: the bag is flushed with nitrogen gas before sealing to displace oxygen, preventing oxidative staling. In vacuum + nitrogen flushing (gas flush), the bag is first evacuated and then back-filled with nitrogen, achieving very low residual oxygen levels (typically under 1%). In nitrogen-only flush, nitrogen is injected into the bag as it is being filled and sealed; less complete but simpler.
Coffee filling machines and dosing
Coffee packing machines are typically VFFS-based for ground and whole bean coffee, or premade-pouch machines for block-bottom and premium specialty coffee bags. FFS machines for coffee: a VFFS machine with a side-gusset or block-bottom forming attachment, integrated with a linear weigher or auger filler for the ground coffee dose, a valve-insertion station, and a nitrogen-flush system. Block-bottom FFS machines are a specific type with a complex forming and bottom-fold mechanism that is distinct from a standard VFFS machine. Premade block-bottom bag filling machines: similar to premade pouch machines, but designed to open and fill the pre-manufactured block-bottom bags and seal the top. These are the standard for premium specialty coffee roasters at small to medium volumes. Dosing for coffee: linear weighers (single or multi-head) — for whole bean and coarsely ground coffee that does not flow well through an auger; auger fillers — for fine ground coffee, instant coffee, and coffee blends with consistent flowability; volumetric cup fillers — for commodity instant coffee. Key considerations when sourcing a coffee packing machine: bag format and whether using premade bags or roll-stock; valve type and inline valve-insertion requirement; nitrogen flush configuration; dosing method for the specific coffee product; target output speed; whether the machine is designed for dust management (fine coffee powder is a dust-explosion and contamination risk).
Frequently asked questions
Why does specialty coffee use block-bottom bags?
Block-bottom bags (flat-bottom bags) stand upright on the shelf without any external support, giving a premium presentation with the full printed face visible. The rectangular base is formed from the two bottom corner gussets of the bag, which fold out flat when the bag is filled. Block-bottom bags were popularised in the specialty coffee sector because they stand out on shelf, allow large label areas, and are perceived as a premium format. They are now widely used for pet food, nuts, and other premium food products that want similar shelf presence. The machines that form block-bottom bags from roll-stock are more complex than standard VFFS machines and are a specialist category.
How much nitrogen is used per bag in coffee packing?
Nitrogen consumption in coffee packing depends on the bag size, the flush method, and the target residual oxygen level. For a 250g coffee bag with a vacuum + nitrogen backfill process targeting under 1% residual O₂, nitrogen consumption is approximately 0.5–1.5 litres per bag (at atmospheric pressure equivalent). For nitrogen-only flush without vacuum, consumption is higher as the flush must physically displace oxygen from the bag cavity — typically 3–5 litres or more per bag. Industrial nitrogen is typically supplied as a liquid in bulk tanks or from on-site nitrogen generators (pressure swing adsorption or membrane separator), which offer lower cost per litre than cylinder gas at production volumes.
Can a coffee packing machine also pack tea?
Many coffee packing machines that use auger fillers can also pack fine-leaf tea, herbal tea, or tea blends — the product flows similarly to ground coffee. Whole-leaf tea requires a different dosing approach (linear weigher or volumetric) since it does not flow through an auger. Specialised tea packing machines that produce string-and-tag tea bags, pyramid tea bags, or envelope pouches are a different category of machine. A VFFS machine with appropriate dosing can typically pack ground coffee, fine-leaf tea, and herbal blends on the same machine with product changeover. Confirm with the machine supplier that the product range planned is compatible with the specific dosing and filling system.
