What bean packers are asking for
Coffee, cocoa, pulses and roasted snack beans share one problem: they lose aroma and gain moisture. Buyers now ask for structures that hold a tight oxygen and moisture barrier, run at speed on existing fillers, and still meet a recyclability or compostability brief. The pouch format has to fit the roaster's degassing window, not the other way round. That is the shift behind most current bean packaging briefs.
Three requests come up again and again. A high-barrier laminate for whole bean coffee that still allows CO2 to escape. A mono-material PE or PP pouch for brands under extended producer responsibility fees. And a shorter run length, so a limited roast or a test SKU can launch without committing to a full rotogravure cylinder set.
Choosing the barrier structure
Barrier is a number, not a slogan. Whole roasted beans release carbon dioxide for several days after roasting, so the pack needs a one-way degassing valve plus a film that blocks oxygen and water vapour. PET/AL/PE gives the strongest barrier and the longest shelf life. PET/NY/PE trades a little moisture resistance for better puncture and flex-crack performance on a fast vertical form-fill-seal line.
For ground beans and flavoured products, oxygen transmission matters more than aroma retention. Metallised PET or an EVOH layer can sit between the print web and the sealant web. Kraft paper laminates suit a matte, natural look but need an inner barrier layer if the pack will sit on a shelf for months. Ask for the transmission figures before you approve artwork.
Recyclable and compostable options
Mono-material PE and PP pouches are the main recyclable route for bean packs. They run on standard fillers, accept a zipper and a valve, and avoid the multi-material laminate that most kerbside schemes reject. The trade-off is a higher sealing temperature window and slightly lower barrier than an aluminium foil laminate, so the shelf life claim has to be tested, not assumed.
PLA/PBS compostable films and degradable options exist for brands selling into collection schemes or events. Compostable structures usually have a shorter shelf life and a narrower heat-seal range. They also need a certified composting route at the point of disposal. Check the local rule before you put a compostable claim on the front of the pack.
Formats, valves and fill rates
Flat bottom pouches stand on the shelf and hold a large print area. Stand up pouches cost less per unit and run fast on existing lines. Side gusset bags suit 1 kg and 5 kg wholesale packs. Spout pouches, including corner spout and STANDCAP, work for cold brew concentrate and liquid products rather than dry beans. Rollstock film is the lowest unit cost at volume.
Add-ons change the fill process. A one-way degassing valve must sit above the fill line, or beans block it. A zipper needs a wider seal area and a slower jaw close. A tear notch has to line up with the top seal. Send the filler's jaw width, fill weight and line speed with the brief so the structure is built around the machine, not after it.
What drives the unit price
Four things move the price: print method, material, order quantity and add-ons. Rotogravure printing runs up to 10 colours and gives the lowest cost per pouch at volume, but needs cylinders and a longer setup. Digital printing skips the cylinders and suits short runs, variant packs and test launches. Flexographic sits between the two for simple designs.
Quantity sets the floor. Low MOQ runs start from 100 pcs for pouches and 10 kg for film with digital printing. Rotogravure runs start from 10,000 pcs or 200 kg. Lead time follows the same split: digital print runs ship in 10-15 working days after artwork approval, rotogravure in 20-25 working days. Free stock pouch samples are available; the customer pays courier only.
Mistakes that cost a run
The most common error is approving artwork before the structure is fixed. Colour, seal position and valve placement all depend on the film build, so a design approved against the wrong laminate has to be redone. The second is forgetting the degassing window: a valve that is too small lets the pouch balloon, and one that is too large lets oxygen in.
Specifying a recyclable film without checking the filler's seal temperature - Choosing a window patch that weakens the barrier - Ordering film without confirming the core diameter and unwind direction - Leaving no space for the valve above the fill line - Assuming a compostable pouch will match the shelf life of a foil laminate
Send the fill weight, line speed, shelf life target and disposal route with the enquiry. Those four answers decide the material, the print method and the order quantity, and they prevent a reprint.
