Premade Pouch Packing Machine — FAQ

Most factories start looking at automation when they're hand-filling more than 2,000–3,000 pouches per day. At that volume, you're paying 2–4 workers just to scoop, seal, and pack — and the inconsistency in fill weight and seal quality is already costing you in customer complaints.

Here's the math: 4 workers × $15/hr × 8hr = $480/day in labor. A premade pouch machine at 20~60 pouches/minute does that volume in under 2 hours with 1 operator. ROI: 8–14 months on labor savings alone.

The hidden trigger: if customers are complaining about inconsistent fills, leaking seals, or variable package appearance, you've already crossed the threshold. The machine isn't just about speed — it's about consistency that protects your brand.

Before choosing a machine, confirm these four points:

1. Is your bag a premade pouch? — Premade pouch machines only work with pre-made bags (not roll-fed film). If your bags arrive flat and pre-sealed on 3 sides, they're premade pouches.

2. What type of pouch do you use? Premade pouch machines can handle: flat bags (3-side seal), stand-up pouches (doypack), zipper pouches, side-gusset spouted pouches, and shaped/special-form pouches.

3. Is your pouch size within the machine's range? — Check the pouch width and height against the machine's gripper range (80–400mm). Extreme sizes may need a specific model.

4. Is your product special? — Some products (highly viscous, sticky, dusty, or corrosive) require specific filling systems. This needs individual consultation with our technical team.

Best advice: send us your product and pouch samples. We'll test them and send you a video before you decide — this service is completely free.

Cost Item	Typical Range	Notes
Machine	$15,000–$100,000+	Depends on speed, filling system, options
Shipping & import	$2,000–$8,000	Sea freight + customs + duties
Installation	$1,500–$5,000	Usually 2–3 days on-site
Operator training	Included or $500–$2,000	1–3 days
Premade pouches	$0.05–$0.50/bag	THE big ongoing cost
Compressed air	$1,000–$3,000	If you don't have one
Electrical install	$500–$2,000	Dedicated circuit
Spare parts kit	$500–$2,000	Sealing bars, Teflon tape, filters
Annual maintenance	$1,000–$3,000	Wear parts, calibration, service

Surprise cost: premade pouches cost 3–5x more than roll stock film. If annual volume is over 2 million pouches, consider VFFS for material savings. Under 500K? Premade pouch is the right call.

Go premade pouch if:

• Multiple products or pouch sizes, frequent changeover (15 min vs 45–90 min for VFFS)
• Pouches have zippers, spouts, or complex shapes VFFS can't make
• Operators aren't highly skilled — loading bags is simple
• Production runs under 500,000 pouches/SKU/year
• Shelf presentation matters — premade pouches look better

Go VFFS if:

• Same product, same bag, long stretches without changeover
• Annual volume over 2 million — material savings pay for the machine
• Operators can handle film threading and collar adjustments
• Need maximum speed (60–100+ BPM vs 30–50 BPM)

Common mistake: buyers choose VFFS because the machine price is lower, then discover operators can't handle film tracking — constant downtime. If your team is new to packaging, premade pouch is the safer bet.

Common complaints and how Lintyco is different:

• "Build quality was poor" — Every machine goes through a 48-hour continuous run test with your product. We encourage factory visits or live video inspections.
• "No after-sales support" — Dedicated support team, WhatsApp/WeChat response within 4 hours. Remote video troubleshooting. Global technician dispatch.
• "Parts don't fit" — Omron PLCs, Siemens contactors, name-brand pneumatics. SS304 frame, laser-cut with CNC precision.
• "Manual was useless" — English docs with actual photos, video tutorials for every maintenance procedure, remote training sessions.

Our suggestion: ask for a live video call where we run your product in real-time. See actual performance, not a curated demo reel. We also provide customer references in your region.

1. Your product — what is it? (powder, granule, liquid, paste, solid) — send a photo or video
2. Product characteristics — bulk density, particle size, viscosity, flowability
3. Your pouch — style, dimensions, material — or send a sample
4. Fill weight — target weight and acceptable tolerance
5. Desired speed — pouches/minute (or daily target + shift hours)
6. Current situation — hand-filling? upgrading? new line?
7. Utilities available — voltage, phase, compressed air?
8. Certifications — CE, FDA, GMP, etc.

A 30-minute conversation saves weeks of back-and-forth emails.

"Up to 60 BPM" is a dry cycle speed — empty pouches, no product. Real production speed depends on filling system, pouch complexity, product characteristics, and fill weight.

Realistic field speeds:

• Powder in zipper pouch, 250g: 25–35 BPM
• Granules in stand-up pouch, 500g: 30–40 BPM
• Liquid in spouted pouch, 200ml: 25–35 BPM
• Small solid pieces in flat pouch, 100g: 35–45 BPM

Always ask the supplier to test your product and pouch and send a video of the actual run.

Pouch width ranges: 80–200mm / 120–260mm / 200–300mm / 300–400mm (varies by model)
Styles: Stand-up (doypack), flat bottom, 3-side seal, 4-side seal, zipper, spouted, gusseted, shaped/special-form.

Key spec: the gripper range. Different models cover different pouch size ranges. Tell us your exact dimensions so we confirm the right machine model.

Filling accuracy depends on your product type. Here's a reference:

Product Type	Typical Error Range	Notes
Granules / solids	±0.5–1%	Free-flowing, most stable
Powders	±1–2%	Depends on density consistency
Liquids	±0.5–1%	Piston filler, very consistent
Viscous / paste	±1–3%	Product dependent, may need special pump

These ranges are for reference only — actual results depend on product properties, pouch size, and filling system configuration.

For pharma/nutraceutical or industries requiring regulatory audit functions: we can provide a higher-grade HMI and PLC with full data logging, recipe traceability, and audit trail capabilities.

Worth it:

• Recipe storage (48+) — essential for multi-product. Changeover drops from 30 to 15 minutes.
• No-fill, no-seal detection — prevents sealing empty pouches. Pays for itself in months.
• Dust extraction — not optional for powders, it's a requirement.

Skip: Built-in embossing (standalone coder is cheaper), automatic magazine loader (only for 24/7).

• Electrical: 220V single phase or 380V three phase, dedicated circuit with grounding
• Compressed air: 0.6–0.8 MPa (85–115 PSI), clean and dry. Minimum 2–3 HP compressor.
• Floor space: Machine ~1.5×1.5×1.8m. Plan at least 4×3m total for operator, materials, and maintenance access.
• Environment: 10–40°C, humidity 30–70%. High humidity affects heat sealing.

Pro tip: get compressed air and electrical ready before the machine arrives. We provide a detailed pre-installation checklist with every order.

Premade pouch machines are much simpler to operate than VFFS. The fundamental operation: load pouches → pour product → select recipe → press start.

Training timeline:

• Day 1: Load pouches, start/stop, HMI navigation, daily cleaning
• Day 2: Recipe selection, parameter adjustments, basic troubleshooting (clearing jams)
• Ongoing: Advanced adjustments learned over the first month

Biggest challenge isn't operation — it's recognizing quality issues. Operators need to know good seal vs. bad seal. We provide a visual quality guide with defect photos.

Total changeover: 15–30 minutes (vs. 45–90 min for VFFS).

1. Product weigher can select new recipe on touchscreen (15 sec) — all parameters auto-load
2. Replace pouches in magazine (2–3 min) by setting number in touch screen
3. Adjust filling system if product changed (10–15 min)
4. Jog Run 10–20 test pouches to verify (5 min)
5. Start production

If only changing pouch size (same product): just swap pouches and adjust gripper width through HMI. No mechanical changes.

Gotcha: switching between radically different products (dusty powder → liquid) requires thorough cleaning — adds 30–60 minutes.

One machine can handle multiple products IF:

• All pouches within the same size range (150–300mm wide)
• Same filling system type (all powders OR all liquids — not mixed)
• No more than 2–3 product switches per shift

Need separate machines if:

• Both powders and liquids (different filling systems)
• Pouch sizes span a very wide range (100g snack AND 2kg pet food)
• Switching products every hour (changeover eats production time)

Most common setup: one machine per product category — one for powders, one for granules, one for liquids.

Seal temperature depends on film material, machine speed, and ambient conditions.

Fine-tuning method: Start with film supplier's recommended range, run 20 pouches.

• Seal too weak (opens easily): increase by 5°C
• Seal wrinkled: decrease by 5°C
• Seal looks good: pull test — grab both sides and pull hard. Good seal tears the film, doesn't separate at the seal line.

Save in the recipe and write the temperature on a sticker near the machine. Eliminates the "who changed the temperature?" problem.

Lintyco machines store up to 48 recipes with all parameters: gripper position, seal temperature, fill weight, machine speed, filling system settings.

Main machine: can store 3–5 pouch parameter recipes covering different pouch sizes, sealing parameters, and timing settings.

Dosing / filling system: also has its own parameter recipe function based on product type — fill weight, auger speed, agitation settings, etc. are saved and recalled together.

Recall: tap recipe number → all settings load → load correct pouches → run test → start production.

Shift start (10 min): Visual inspection → load pouches → fill hopper → select recipe → run 10 test pouches → verify fill weight and seal quality → start production.

During production: Monitor pouch magazine level (reload every 20–30 min), top up hopper, spot-check fill weight every 30 minutes, watch for seal quality issues.

Shift end (15 min): Empty hopper → clean seal bars → wipe down machine → log production count and any issues.

When	What	Time
Every shift	Clean seal bars & filling nozzles. Check magazine for stuck pouches.	10 min
Weekly	Check pneumatic lines, gripper wear, lubricate guides, drain air filter.	30 min
Monthly	Calibrate fill weight. Inspect Teflon tape. Check sensors. Full clean.	1–2 hr
Quarterly	Replace Teflon tape. Check drive belts. Inspect electrical connections.	2–3 hr
Annually	Full inspection: bearings, bushings, servos, PLC battery. Replace wear parts.	Half day

The $20 Teflon tape lesson: the most expensive "repair" is a seal bar running with degraded tape. $20 tape saves a $300–$500 seal bar and thousands of rejected pouches.

Part	Qty	Cost
Teflon tape for seal bars	5 sets	$20/set
Sealing bar (upper + lower)	1 set	$300–$500
Pneumatic cylinders (gripper)	2	$50–$100 ea
Air filters	5	$10 ea
Solenoid valves	2	$30–$80 ea
Auger/piston seals	2 sets	$50–$150
HMI fuses	5	$2 ea
Drive belts	2	$30–$60 ea
Photoelectric sensors	2	$40–$80 ea

Total kit: ~$1,000–$2,000. Covers 95% of unplanned downtime causes. Lintyco ships from stock within 24 hours via DHL Express.

After every run: Empty hoppers → remove & wash auger/piston/cups (quick-release) → wipe seal bars with damp cloth → blow out funnel with compressed air → wipe magazine and conveyor.

Weekly deep clean: Remove all product-contact components, wash with food-safe detergent → clean frame with stainless steel cleaner → vacuum product dust from enclosure → clean sensors.

Allergen changeover: Full disassembly + wash of ALL product-contact surfaces. 1–2 hours. Document in allergen control log.

Common mistake: using too much water. This is an electrical machine — use damp cloths, not hoses.

• WhatsApp/WeChat: Response within 4 hours (1 hour for production-stopped emergencies)
• Remote video diagnosis: Video call, technician watches via phone camera, walks operator through fix. Resolves 70–80% of issues.
• On-site technician: China 1–3 days. International 5–10 days.
• Spare parts: Ship from stock within 24 hours via DHL Express.

Minimize downtime: keep the spare parts kit, train 2+ operators, send photos/videos when contacting support.

1. Follow the maintenance schedule — skipping it is the #1 reason machines die early
2. Replace Teflon tape on time — degraded tape destroys seal bars
3. Keep the PLC battery fresh — replace every 2 years or you lose all recipes
4. Use clean, dry compressed air — moisture in pneumatics causes corrosion
5. Don't over-tighten — mechanical adjustments should be finger-tight + 1/4 turn
6. Train multiple operators — one operator's bad habits can shorten machine life

Factories that follow the schedule consistently see 10–15 year lifespans. Those that skip it replace machines in 3–5 years.

Systematic checklist:

1. Seal bar condition (most common hidden cause) — Remove Teflon tape, check surface. Pitted/damaged bars create uneven pressure no temperature fix can solve.

2. Seal area contamination — Look at failed pouch under good light. Product residue, dust, or moisture prevents film fusion. Fix: dust extraction for powders; check filling nozzle retraction for liquids.

3. Sealing pressure — Check air pressure ≥ 0.5 MPa. Check bar alignment (parallel).

4. Film/pouch material — Changed suppliers? Different films seal at different temps.

5. Machine timing — Speed increased without adjusting dwell time? Check recipe settings.

Quick diagnostic: seal a clean empty pouch. If it seals perfectly → contamination from filling. If it still fails → temperature, pressure, or bar condition.

Wrinkled after sealing: Temperature too high → lower 5–10°C. Pressure too high → reduce pneumatic pressure. Cooling station not working → check it's active.

Crooked/misaligned: Gripper not centered → recalibrate. Inconsistent pouch dimensions → supplier quality issue.

Tears/holes: Sharp edge on filling funnel → inspect and deburr. Gripper closing too hard → reduce pressure. Product pieces too large for filling tube → check max piece size.

1. Safety sensor — Door slightly ajar or dirty sensor. Check all doors/guards, clean safety sensors.
2. E-stop button — Bumped during operation. Check all E-stops (usually more than one) — twist to unlock.
3. Overload protection — Motor detected jam/blockage. Check pouch path, sealing station, filling mechanism. Clear blockage, reset overload on motor contactor.
4. PLC communication lost — Restart machine. If recurring, check PLC battery and communication cable.

If none work: power cycle (off, 30 sec, on). Fixes 90% of unexplained stops. Recurring = electrical issue needing professional diagnosis.

Category	Price Range	What You Get
Entry-level	$15,000–$25,000	8-station rotary, pneumatic filling, 20–35 BPM, limited recipes
Mid-range	$25,000–$60,000	PLC 48+ recipes, 30–50 BPM, more pouch styles, better filling system
High-speed	$60,000–$150,000+	High-speed, check-weigher feedback, 50–80 BPM, custom configurations

Price varies based on: product attributes (powder, liquid, granule, paste), pouch type and size, special requirements (certifications, material grade, brand-name components), and filling system complexity.

Watch out: some suppliers quote low base prices but charge extra for HMI, safety guards, or filling system. Always ask for an all-inclusive quote.

Scenario: Granular product, 500g pouch, hand-filling 3,000 pouches/day

Factor	Without Machine	With Machine
Labor	4 workers × $15/hr × 8hr = $480/day	1 operator × $15/hr × 3hr = $45/day
Material waste	~5% overfill + 3% seal failures	~1% overfill + <1% seal failures
Monthly labor	~$10,000	~$1,000
Monthly material savings	—	~$2,000
Monthly savings	—	~$11,000

Machine cost: ~$35,000 (mid-range). ROI: 3–4 months. Even conservatively ($5–8K/month savings), most operations reach ROI within 6–12 months.
