A single packaging machine cannot adapt to all materials. Huapack provides material-oriented customized packaging solutions, matching exclusive feeding modes, precision metering systems, and stable discharging structures for powders, granules, liquids, pastes, and special materials. We solve full-process packaging pain points, ensuring stable mass production and high-standard packaging quality.
For powder materials prone to dust emission, agglomeration, spillage, and difficult dosing, Huapack adopts high-cleanliness, dust-control technical solutions. Equipped with closed-loop negative pressure conveying, high-precision screw metering, integrated dust collection system, anti-bridging agitator hopper, photoelectric tracking, and intelligent PLC programming, the equipment effectively reduces powder escape and solves dosing inaccuracy. It is widely applicable to corn starch, veterinary powder, dialysis powder, polyethylene glycol powder, food additives, and nutritional fortifiers.
Huapack 180N HFFS packaging machine: For fine powder packaging within 200ml, dosing accuracy ±1g, running speed 40-60 packs/min.
Huapack 240ND HFFS packaging machine: For large-capacity powder packaging, compatible with 3-side seal, 4-side seal and flat pouches.
A Malaysian veterinary pharmaceutical enterprise needed automated packaging for 40g veterinary powder. The material featured poor fluidity and high dust, requiring high precision and high cleanliness. The customer adopted Huapack 180N screw metering packaging line. After commissioning, the production speed reached 50-55 bags/min with dosing error strictly controlled within ±1g. The closed negative pressure dust collection system optimized the workshop production environment, replaced inefficient semi-automatic production, reduced labor costs, and greatly improved single-shift output and packaging consistency.
Aiming at granule material pain points such as breakage, equipment jamming, uneven particle size, and unstable discharging, Huapack’s granule packaging solution features vibratory orderly feeding, multi-head combination gravity weighing, and soft-bag horizontal forming structure. It supports multi-station independent dosing for mixed granule materials, with outstanding anti-breakage and high-adaptability performance, suitable for nuts, dried fruits, grains, quinoa, pet food, puffed snacks, and mixed granules.
Huapack 180N HFFS machine: single-lane speed up to 45 bags/min, multi-lane speed 45-85 bags/min.
Huapack 240NG-5, 180NG, 240DG and other pre-made pouch machines: compatible with stand-up pouches, zipper pouches and various sealed pouches, ideal for salt, bath salt and grain packaging.
A Vietnamese seafood processor faced low efficiency and high breakage rate in manual and semi-automatic packaging of 100g irregular crispy fish blocks. The customer chose Huapack 240DG pre-made pouch packaging machine equipped with a 14-head combination weigher. The vibratory feeding and soft-landing discharging structure greatly reduced material breakage. The stable running speed of 75-80 bags/min effectively reduced material loss, providing stable production capacity for the customer’s export business expansion.
For liquid materials with different fluidity that are prone to dripping and splashing, Huapack’s liquid packaging solution realizes full closed-loop filling. Equipped with peristaltic/diaphragm pump feeding, flow/piston volumetric dosing, and lift-type suck-back filling nozzles, it completely solves liquid dripping and bag mouth contamination, ensuring high hygiene and high precision. It is widely used in functional drinks, fruit purees, enzyme liquids, and concentrated detergent liquids.
Dual/four-lane straight-spout liquid filling machine: speed 80-150 bags/min. ZGY-6000 capping & filling integrated machine: suitable for large-volume spout pouch health drink production. 240ND/330SD HFFS machines and 180DG/400QG pre-made pouch filling lines: support fast model changeover and stable continuous production.
A Chinese health drink manufacturer suffered from dosing fluctuations and nozzle dripping in traditional equipment, leading to unqualified sealing and defective products. By adopting Huapack 400QG piston volumetric filling line with lift-type drip-free nozzles, the production speed reached 110-150 bags/min with accuracy within ±1ml. The suck-back design eliminated residual liquid at the pouch mouth, significantly improving the sealing pass rate, meeting the high hygiene standards of health drinks, and supporting export batch production.
High-viscosity pastes are easy to adhere to equipment walls, layer, and pollute sealing edges, resulting in inaccurate dosing and false sealing. Huapack’s exclusive paste packaging solution adopts temperature-controlled agitated hoppers and screw forced feeding, matched with pressure-stabilized volumetric dosing technology. Equipped with non-stick coated precision screw injection, automatic metering cup scrapers, and bag mouth cleaning devices, it effectively prevents material separation, solidification, and metering drift, ensuring clean and firm sealing.
Huapack 180DG pre-made pouch machine: stable sealing for high-viscosity materials, speed 45-80 bags/min. 240DG/280DG machines: support quick die change, suitable for multi-SKU batch production.
A Shanghai seasoning enterprise’s traditional packaging equipment had serious tomato sauce wall adhesion and sealing contamination problems, with high reject rates. After switching to Huapack 240NG packaging line with temperature-controlled stirring and non-stick injection system, the equipment stably ran at 35-40 bags/min with dosing accuracy within ±1g. The automatic bag mouth cleaning function greatly improved sealing quality, reduced defective rates, and helped the customer enter high-end retail channels.
For corrosive agrochemicals, sterile pharmaceutical materials, and easily oxidized special materials, Huapack upgrades mature standard equipment with targeted functional modules instead of redeveloping new machines. Key contact parts can be upgraded to 316L stainless steel or anti-corrosion coating, and sealing parts adopt acid and alkali resistant fluororubber, adapting to harsh production environments.
Closed isolation dust removal module: for traditional Chinese medicine powder and feed premix to control dust diffusion. Nitrogen flushing module: for oxidized and moisture-sensitive materials to extend product shelf life. CIP self-cleaning module: realizes residue-free quick switching for multi-product small-batch production. Explosion-proof module: CE certified, suitable for flammable agrochemical materials.
An East China agrochemical exporter needed to package corrosive chlorine-containing granular fertilizer. The customer customized Huapack 240NG anti-corrosion packaging line with closed dust removal system. After two years of continuous operation, no corrosion occurred on equipment contact parts, and dust emission was effectively controlled. The solution helped the product pass international import inspections and became the standard packaging line for the customer’s export orders.
For composite packaging scenarios requiring simultaneous packaging of powder, granule, and liquid materials, Huapack provides one-stop intelligent whole-line solutions covering feeding, multi-station dosing, pouch forming, sealing, case packing, and palletizing. The whole line supports MES remote monitoring, production data traceability, and quick die change, meeting customers’ long-term capacity expansion and intelligent production upgrade needs.
