Sachet Packing Machine Suppliers & Manufacturers

Sachet packing machines produce small, sealed portion-pack pouches — the standard format for sauce portions, sugar, salt, coffee sachets, shampoo samples, condiment sachets, powdered drink sachets, and pharmaceutical powder or liquid unit doses. The primary machine types are: horizontal form-fill-seal (HFSS) sachet machines — the film is unwound horizontally, the sachet is formed, filled, and sealed in a horizontal process; HFSS is the standard for liquid and viscous products (sauce sachets, honey, shampoo, cosmetic sample sachets) because the horizontal orientation allows controlled filling without spillage. Multi-lane HFSS machines use multiple forming tubes side by side to produce multiple sachets simultaneously — dramatically increasing production output; standard multi-lane configurations are 4–20 lanes for small sachets (5–30mL). Vertical sachet machines (based on VFFS technology in small sachet format) form sachets vertically from a film roll — used primarily for powder and granule sachets (sugar, salt, coffee, spice, dried soup powder). Stick pack machines produce a narrow cylindrical sachet (a 'stick') — the standard format for single-serve coffee, tea, sugar, and powdered supplement sachets; stick packs are narrow and tall, fitting into a standard mug or cup opening. Doy-pack sachet machines produce small stand-up sachets — used for premium single-serve liquid products, honey, and concentrated food sachets where a premium appearance is needed. Machine performance parameters: sachet size range (width × height), fill volume or weight range, number of lanes, production speed (sachets per minute per lane), film compatibility (single-layer, laminate, metallised — the same film types used for standard flexible pouches).

Sachet film selection is critical for product shelf life and seal integrity — the film must provide adequate oxygen, moisture, and light barrier for the product shelf life, and must be sealable on the machine's jaw type and sealing temperature. Common sachet film structures for food applications: plain polyethylene (PE) — for short shelf life or ambient-temperature sauce sachets and non-barrier applications; PET/PE laminate — a standard structure providing moderate oxygen and moisture barrier, good print surface, and reliable seal performance; metallised OPP/PE or PET/aluminium foil/PE — for oxygen-sensitive products (coffee, powdered drink, pharmaceutical) requiring maximum barrier. Hermetic sealing is essential for food safety — a sachet with an incomplete heat seal provides a direct path for microbial contamination, oxygen, and moisture. Sachet machines use heated jaw bars to seal the film — the seal temperature, dwell time, and jaw pressure must be optimised for each film structure, and seal quality should be monitored by tensile peel testing during production. For sauce, condiment, and food-service sachet applications, the seal must also prevent leakage under the mechanical stresses of distribution and handling. When sourcing sachet packing machines from Chinese manufacturers, specify: product type (liquid, sauce, powder, granule), sachet size range, fill volume or weight range, number of lanes, film type, required production speed (sachets per minute), and any regulatory requirements (CE certification for EU market). Chinese sachet machine manufacturers offer competitive pricing — a standard 4-lane liquid sachet HFSS machine is typically $8,000–20,000; an 8–16-lane automatic machine is $20,000–60,000.
