Unlike conventional packaging machines limited to single-chamber liquid filling, MP-350 supports multi-cavity molding (single, dual, triple, eight-chamber customizable), liquid, powder, granule, paste dual-mode filling, and laser custom irregular contour cutting, enabling enterprises to launch differentiated premium pod lines including multi-functional laundry pods, composite dishwasher capsules, agrochemical pesticide fertilizer soluble sachets, and personal care single-dose cleansing pods with zero additional equipment investment. With a core cycle speed of 0.75 seconds per row regardless of cavity configuration, the machine balances peak productivity and consistent molding quality, positioning itself as the most cost-effective high-throughput flatbed packaging core equipment for enterprises scaling soluble product market share across Europe, Southeast Asia, North America, and Latin America.

The MP-350 adopts an advanced closed-loop flat annular circulation structural frame, abandoning the intermittent feeding limitation of linear packaging machines and the mechanical fatigue risk of high-speed rotary drum devices, achieving synchronous coordination of film unwinding, constant temperature pre-conditioning, vacuum thermoforming, multi-channel filling, constant-pressure heat sealing, laser cutting, finished product separation, and automatic material recovery within a unified cyclic workflow. Its core row cycle speed reaches 0.75 seconds per row, supporting scalable adjustment of lane quantity and cavity layout, with maximum comprehensive output up to 800 pieces per minute under standard single-row multi-chamber configuration, far exceeding the production capacity of mid-tier 350-class packaging equipment in the global market. To resolve the inherent brittleness and cracking risk of PVA film under long-time high-speed tension, POLYVA integrates a constant microclimate protection cabin inside MP-350, maintaining stable environmental parameters of 25±2°C temperature and 40%–45% relative humidity throughout the film conveying path; this patented humidity-temperature locking technology keeps PVA film flexible and uniform during high-speed stretching and molding, reducing film breakage rate to below 0.8% even under 7×24-hour continuous industrial operation, a benchmark level superior to mainstream competitors. The whole machine frame is constructed with thickened SUS304 stainless steel welded structure, reinforced load-bearing base and anti-vibration buffer foot pads, eliminating resonance vibration during high-speed cyclic movement; all transmission components adopt imported precision gear reducers and synchronous belt drive systems, ensuring zero displacement deviation of mold positioning after 10,000 hours of cumulative operation. For large factories pursuing uninterrupted mass production, MP-350 is certified for non-stop continuous operation with built-in heat dissipation optimization module for servo motors, filling pumps and sealing heating plates, avoiding thermal shutdown failures caused by long-hour load operation, and realizing annual stable production capacity support for tens of millions of soluble pods without major downtime maintenance. Compared with traditional low-speed packaging machines requiring frequent shutdown cooling and component replacement, MP-350 cuts production downtime loss by 65% and significantly boosts effective production time ratio.

One core competitive advantage of POLYVA MP-350 lies in its fully modular interchangeable filling system, designed to adapt to five major filling mediums: low-viscosity cleaning liquid, high-viscosity fabric softener gel, fine detergent powder, slow-release fragrance granules, and thick emulsifying paste, covering all mainstream soluble pod formulation requirements in home care and agrochemical industries. Each independent filling station is equipped with a servo-driven high-precision plunger metering pump with closed-loop feedback correction, delivering filling accuracy of ±0.02ml for liquid materials and ±0.05g weight tolerance for solid powder/granule materials, completely eliminating underfilling leakage and overfilling raw material waste problems plaguing ordinary packaging machines. The filling pipeline adopts detachable SUS316L food-grade corrosion-resistant material, resistant to alkaline detergent, acidic stain remover, enzyme-containing biological formula, and agricultural chemical solvents, with no chemical reaction or contamination risk to packaged products, fully complying with FDA, HACCP and EU REACH hygiene standards. MP-350 supports independent multi-channel separate filling for multi-cavity molds: dual-chamber pods can simultaneously inject detergent and fabric conditioner, triple-chamber pods match stain remover, bleach and fragrance agent, four-chamber composite pods realize four-component functional separation, enabling manufacturers to develop high-margin differentiated products without purchasing multiple standalone filling machines. The machine integrates an automatic filling parameter compensation algorithm, which dynamically adjusts pump stroke, filling speed and material feeding pressure in real time according to material viscosity, ambient temperature and batch formula changes; manual parameter re-calibration is unnecessary during raw material batch switching, maintaining consistent filling precision across all production batches. The removable integrated filling head assembly allows one-piece disassembly and replacement within 10 minutes, greatly accelerating product formula switch efficiency for enterprises with diverse SKU layouts.

Addressing the universal industry pain point of long mold changeover downtime for soluble pod equipment, POLYVA equips MP-350 with proprietary one-key rapid conversion technology, realizing full production switch between different pod specifications, cavity quantities and shapes in 15 minutes or less, a breakthrough improvement from the 2–4 hour changeover time of conventional flat packaging machines. The mold base adopts quick-lock pneumatic clamping structure with positioning pin automatic locking, no manual bolt tightening required during mold replacement; mold cavity groups are modular standardized design, compatible with all POLYVA standard molds and customer custom molds, covering pod weight range of 1g to 30g, the mainstream specification interval for consumer soluble pods and agricultural unit-dose sachets. Beyond standard square, round and oval pod shapes, MP-350 is fitted with high-precision laser contour cutting system, supporting personalized irregular shape molding including star, heart, dolphin, logo embossed contour and brand exclusive custom silhouette; the laser cutting head features closed-loop positioning correction, ensuring smooth cutting edge without film pulling damage, maintaining complete water solubility of PVA film edge sealing area. The intelligent HMI touchscreen stores up to 50 groups of preset product recipe data, with one-click recall of molding temperature, film tension, filling volume, sealing pressure and cutting position parameters for each SKU; new product parameter settings can be saved directly to the recipe library after trial production, eliminating repeated debugging during re-production and lowering technical threshold for novice operators. For small-batch trial production and large-batch mass production switching, MP-350 flexibly adjusts operation speed and mold activation quantity, supporting semi-load low-speed trial run and full-load high-speed mass production mode switching to meet brand new product testing and bulk order delivery dual demands.
