Dry food packaging must protect the product from moisture ingress (which causes caking, mould, and quality deterioration), oxygen (which causes oxidative rancidity and flavour loss in high-fat products), and physical damage during distribution. The packaging format choice depends on the product's water activity (aw) and moisture sensitivity, fat content (which affects oxidation sensitivity), product fragility, target retail format, and distribution logistics. Key packaging formats for dry food: flexible stand-up pouches (the dominant retail format for snack food, coffee, tea, dried fruit and nuts, spices, and premium dry goods — available in barrier laminate constructions with aluminium foil, metallised film, or EVOH for oxygen and moisture protection); kraft paper bags (the standard for flour, sugar, rice, seeds, and bulk dry goods — food-grade kraft with PE inner liner for moisture-sensitive products; multiwall kraft for heavy bulk formats); folding cartons (cereal, tea, confectionery, biscuit, snack bar, and dry pasta outer packaging — the SBS board carton with a primary flexible inner bag is the standard cereal pack format); woven polypropylene sacks (for rice, flour, sugar, seeds, animal feed, and bulk dry commodity export — see woven PP bag page for specification detail); rigid plastic jars (PP or HDPE jars for dried herbs and spices, ground coffee for food service, protein powders, and premium snack trail mixes); composite paper tubes and cans (for snack tubes, pringles-style crisps, and premium dry food with cylindrical packaging). Moisture barrier specification for the flexible pack must be matched to the product's moisture sensitivity — expressed as moisture vapour transmission rate (MVTR, g/m²/day at 38°C and 90% RH). For moisture-sensitive biscuits and crackers, a low MVTR of < 1 g/m²/day is required; for coffee (high oxygen sensitivity), an oxygen transmission rate (OTR) of < 1 cc/m²/day is the standard.
Coffee, tea, and snack packaging specifics
Coffee packaging has specific requirements: freshly roasted coffee off-gasses CO₂ for days after roasting — a one-way degassing valve is required on the pouch to allow CO₂ to escape without allowing oxygen to enter; standard degassing valves are pressure-relief membrane valves applied to the flat panel of the pouch. Coffee pouch formats are predominantly stand-up pouches in 250g, 500g, and 1kg sizes, with a recloseable zip (for ground coffee) or a one-way valve (for whole bean coffee sold in valve bags). Coffee packaging film structures typically use foil laminate or high-barrier metallised film to provide the oxygen barrier required for 12–18 month ambient shelf life. Tea packaging uses a different set of formats: primary tea sachets (the tea bag itself) produced on dedicated tea bagging machines, secondary outer envelopes (individual tea bag envelopes), and tertiary outer cartons. For retail tea, a box of 20–80 individually enveloped tea sachets in a folding carton is the standard format. Bulk loose-leaf tea uses stand-up pouches or foil-lined cartons. Snack food packaging is dominated by pillow bags (VFFS — vertical form-fill-seal) for chips, crisps, nuts, and similar low-to-medium-weight snacks, and stand-up pouches for premium snacks, trail mixes, and branded health foods. Snack film structures must balance moisture and oxygen barrier, machinability on VFFS equipment, and print quality for shelf appeal.
Frequently asked questions
What flexible packaging structure should I use for roasted ground coffee?
Roasted ground coffee requires a high oxygen barrier to prevent oxidative staling, which rapidly degrades flavour. The standard commercial coffee pouch structure is: outer printed OPP or PET print ply / aluminium foil barrier / PE or CPP sealant ply — this provides very low OTR (< 0.5 cc/m²/day) suitable for 12–18 month ambient shelf life. The foil laminate also provides complete light barrier (important for flavour protection in transparent or translucent retail shelf environments). A one-way degassing valve is applied to the finished pouch — allowing CO₂ off-gassing from freshly roasted coffee to escape without allowing oxygen ingress. For environmentally-positioned coffee brands, all-PE mono-material or compostable coffee pouches are available but may compromise the oxygen barrier performance compared to foil laminate — validate shelf life with your specific roast before committing.
What is the standard inner liner specification for flour bags?
Flour is moisture-sensitive but not oxygen-sensitive — the primary packaging requirement is moisture barrier to prevent caking and mould growth. The standard inner liner for kraft paper flour bags (both consumer retail 1–2kg bags and 25–50kg sack formats) is a PE (polyethylene) film liner — either a sewn-in PE gusset bag or a PE film inner bag inserted into the paper outer. The PE liner provides the moisture barrier; the paper outer provides the structural strength and print surface. For retail flour bags (1–2kg), the outer is typically a BOPP-laminated or kraft paper printed bag with PE inner. For multiwall kraft sacks (25kg, 50kg), a one or two-ply paper outer with a PE film or PE-coated paper inner ply is standard. Flour is typically classified as a food contact application requiring food-grade PE and food-grade paper — confirm food contact compliance documentation with your sack manufacturer.
Can I use a stand-up pouch for spice packaging?
Yes — stand-up pouches are an excellent format for retail spice packaging. For whole spices and dry herbs, a barrier laminate pouch (PET/foil/PE or PET/metallised film/PE) provides the oxygen and moisture protection required. For powdered spices (which have a tendency to cling and settle), an easy-open tear notch and a recloseable zip are standard features. Common retail spice pouch sizes range from 50g to 250g. A zipper reseal is strongly recommended for consumer spice packaging — consumers typically use spices in small quantities over many months. Some spice brands use stand-up pouches with a pour/shake spout or a perforated lid as a more convenient dispensing option. For premium positioning, matte laminate finish with foil-blocked branding on a stand-up pouch provides a strong shelf presence.
