XSR-1200 Heat Sealing & Cold Cutting Bag Making Machine

The XSR-1200 is a servo-driven bag making machine that combines heat sealing and cold cutting in a single production line. It produces T-shirt bags, flat bags, and shopping bags from HDPE, LDPE, and biodegradable film at up to 150 pcs/min. Designed for 24/7 continuous operation in medium-to-large bag factories, the machine uses PLC-controlled registration, German SICK material-stop sensing, and Japanese NSK main bearings for repeatable seal quality across shifts.

Applications

The XSR-1200 covers the most common bag types in retail, food, and industrial packaging. Each application maps to a specific machine configuration for optimal cycle time and seal strength.

• Supermarket T-shirt bags — HDPE or LDPE, 0.008–0.025 mm, produced at 120–150 pcs/min with inline punching and stacking.

• Flat shopping bags — LDPE or biodegradable film, 0.03–0.10 mm, with reinforced bottom seal for heavier loads.

• Garment / soft-goods bags — Thin LDPE, 0.015–0.04 mm, cold-cut edges for clean presentation on retail shelves.

• Food pre-packaging bags — Food-grade PE, 0.02–0.06 mm, precise seal width control to prevent leakage.

• Industrial liner bags — Heavy-duty LDPE, 0.08–0.20 mm, with optional gusseting and perforation.

Application vs Configuration

Who This Machine Is For

• Medium-to-large bag production factories running 2–3 shifts daily, needing consistent output above 100 pcs/min with minimal operator intervention.

• Export-oriented bag manufacturers who need CE-compliant equipment with documented component traceability (SICK, Panasonic, NSK, AIRTAC components as standard).

• Factories transitioning from manual/semi-auto lines — the PLC with 7-inch MCGS touch screen stores 50+ job recipes, reducing changeover time from 30 minutes to under 5.

• Operations running mixed-material jobs — HDPE in the morning, LDPE in the afternoon, biodegradable film for specific orders — without mechanical adjustments between runs.

• Producers targeting waste reduction — servo-driven feeding with Inovance servo and SICK material-stop sensor cuts registration error below ±0.5 mm, reducing film scrap by 3–5% vs pneumatic feed systems.

Who Should NOT Buy This Machine

• Startup bag shops producing under 500 kg/day — a smaller cold-cut-only machine like our High-Speed Cold Cutting Bag Making Machine costs less and fits lower volume better.

• Factories producing only ultra-thin produce bags below 0.005 mm — these need specialized winding and don't benefit from the XSR-1200's heat-seal station. Consider a dedicated film blowing + inline winding line.

• Operations that only run one bag size, one material, one shift — the XSR-1200's quick-change features and servo registration add cost that won't pay back in a single-SKU environment.

Technical Advantages

Servo-Driven Heat Seal & Cold Cut in One Pass

The XSR-1200 runs both heat sealing and cold cutting stations on a shared servo drive train, synchronized through the Ouxin PLC. Unlike two-step systems where bags transfer between separate heat-seal and cold-cut units, this single-pass design eliminates registration drift between stations. The Inovance feeding servo adjusts film tension in real time — when the SICK sensor detects a splice or gauge variation, feed compensation happens within 0.02 seconds. Result: seal-to-cut alignment stays within ±0.5 mm even at 150 pcs/min.

Multi-Material Temperature Control with ±1°C Precision

Each heat-seal blade has independent PID temperature control via the Yatai controller, with a working range of 80–300°C. When switching from thin HDPE (seal temp ~140°C) to thick LDPE (~180°C), the controller ramps to target within 90 seconds. Unlike fixed-temperature systems that over-seal thin film or under-seal thick film, the independent channels let you store material-specific profiles in the MCGS touch screen and recall them with one tap. The solid-state relay (FOTEK) controls heater cycling with zero-crossing switching — no electrical noise that can drift the PLC clock or corrupt encoder counts.

Component Stack Built for 24/7 Duty

NSK main bearings (Japan), Panasonic photoelectric sensor (Japan), SICK material-stop sensor (Germany), AIRTAC/SMC pneumatics. The XSR-1200 doesn't use unbranded alternates on these wear-critical points. NSK bearings at the main drive shaft and sealing cam handle the cyclic load of 150 strokes/min — that's 216,000 cycles per day. Panasonic's CX-400 series photoelectric sensor maintains registration through film opacity variation (clear to white to printed), which generic sensors lose tracking on. This component selection matters most on night shift when maintenance staff isn't on site.

Real Production Issues It Solves

Seal strength drifting between morning and afternoon shifts. Two-shift factories see ambient temperature swings of 10–15°C from morning to afternoon, especially in non-AC workshops. The Yatai PID controller on the XSR-1200 recalibrates every sealing cycle — if the blade temperature deviates by 1°C, heater duty cycle adjusts immediately. Customers report seal strength CV (coefficient of variation) below 3% across a 24-hour run, vs 8–12% on machines with on/off temperature control.

Registration loss after film splice. When the operator tapes in a new roll, the splice thickness is 2–3× the film gauge. Pneumatic-feed machines lose registration for 5–10 bags after every splice. The SICK material-stop sensor on the XSR-1200 detects the splice as a thickness anomaly, and the Inovance servo compensates feed rate through the splice zone. Registration recovery happens within 1–2 bags.

Cold-cut blade wear in high-humidity environments. Factories in coastal or tropical regions (humidity above 70%) see accelerated blade corrosion on cold-cut stations. The XSR-1200 uses D2 tool steel blades with Cr12MoV specification — 12% chromium content provides corrosion resistance while maintaining hardness at HRC 58–60. Blade life in these conditions averages 3–4 months vs 4–6 weeks for standard carbon-steel blades.

Seal bar sticking on biodegradable films. PLA and PBAT blends have a melt temperature window only 15–25°C wide, compared to 50–70°C for LDPE. Standard seal bars with PTFE tape stick to biodegradable film within 2–3 hours of continuous running. The XSR-1200's seal bar uses a ceramic-coated surface (optional upgrade) that reduces sticking — operators report 8–10 hours between cleaning vs 2–3 hours with standard bars.

Production Scenarios

Typical Production Configurations

How It Works

1. Film Unwinding: Motorized unwinding station with pneumatic tension control pulls film from the roll at constant tension. The SICK sensor monitors film presence and triggers auto-stop at roll end.

2. Registration Sensing: Panasonic photoelectric sensor reads printed registration marks (or detects bag length by encoder count for plain film). Position data feeds to the Ouxin PLC in real time.

3. Heat Sealing: Heated blade descends at the programmed position. PID controller maintains set temperature (±1°C). Dwell time is servo-adjustable from the touch screen based on film type and thickness.

4. Cold Cutting: Immediately after sealing, the cold-cut blade shears the film at the registration point. The mechanical linkage between seal and cut stations ensures alignment — no separate timing adjustment needed.

5. Bag Stacking: Finished bags exit onto the stacking table. An optional automatic stacker counts and collates bags into preset quantities (50, 100, 200 pcs) for direct packing.

6. Optional Folding: For T-shirt bags requiring folded presentation, the inline folding unit (optional) folds at up to 6 pcs/min with 1050 mm max width and 1500 mm max length.

Frequently Asked Questions

Performance and Material Compatibility

What bag types can the XSR-1200 produce?

T-shirt bags, flat bags, shopping bags, garment bags, and industrial liner bags. The machine handles HDPE, LDPE, LLDPE, and biodegradable films (PLA/PBAT blends) from 0.02 to 0.20 mm thickness. Bag width up to 1050 mm, length up to 1500 mm.

Can it run biodegradable film without modification?

The standard XSR-1200 runs PLA/PBAT blends, but we recommend the ceramic-coated seal bar upgrade for continuous production. Biodegradable films have a narrower melt window, and the ceramic coating reduces sticking that leads to seal defects and downtime for bar cleaning.

What's the actual output difference between HDPE thin bags and LDPE thick bags?

On 0.010 mm HDPE T-shirt bags: 130–150 pcs/min. On 0.06 mm LDPE shopping bags: 90–110 pcs/min. The speed difference comes from seal dwell time — thicker film needs longer heat penetration for a consistent seal. The machine auto-adjusts cycle rate based on the recipe you load.

Purchasing and Delivery

What's the lead time for an XSR-1200?

Standard configuration: 25–30 working days. With optional upgrades (folding unit, ceramic bar, auto stacker): 30–40 working days. Sea freight transit time varies by destination — typically 15–25 days to major ports in Africa, 20–30 days to South America, 10–15 days to Southeast Asia.

Do you provide local installation support?

Yes. One or two MINGYANG engineers travel to your factory for installation, alignment, and training — typically 5–7 days on site. For regions where we have partner service centers (select countries in Africa and Southeast Asia), local engineers are available for follow-up visits.

How are spare parts handled after warranty?

We stock all wear parts (seal bars, cold-cut blades, heating elements, sensors, belts, bearings) and ship within 48 hours of order confirmation. We provide a recommended spare parts list with part numbers and expected service life so you can stock locally. Most customers keep 3–6 months of wear parts on hand.
