Key Advantages:
✅ Pre-opened bags – no jams, no misfeeds
✅ Integrated printing – no need for separate labelers
✅ Touchscreen control – one‑tap product changeover
✅ Wrinkle‑free, smooth, and firm seals
✅ Casters for flexible mobility – single or multi‑station operation
✅ Interfaces with robotic arms, weigh feeders, MES/ERP systems
Applicable Industries: Sensors, electronic components, automotive parts, hardware tools, home appliance accessories, boxed products, and other lightweight, diversified products.
Packaging Speed: 8‑15 bags/minute
The Thermal Transfer Overprinter is a digital coding solution designed specifically for flexible packaging. It uses heat and pressure to transfer ink from a ribbon onto packaging materials, producing high‑resolution (300dpi), crisp, and durable prints of variable data such as production dates, batch numbers, barcodes, and QR codes.
In one sentence: A professional printer for flexible packaging that delivers clear, scannable, and long‑lasting codes.
Key Advantages:
✅ 300dpi high resolution – prints are sharp and scan‑friendly
✅ Vacuum bag‑flattening – holds bags flat for perfectly aligned prints every time
✅ 107×115mm large print area – covers most packaging label needs in one pass
✅ Up to 600m ribbon capacity – fewer changeovers for continuous production
✅ Industrial PC control – edit and save templates on a touchscreen, no external computer needed
✅ RS‑232 interface – seamless integration with PLCs and production line systems
✅ Adjustable print speed – 50‑600mm/s to match your production pace
Print Speed: 50 – 600mm/s (adjustable)
Applicable Materials: Plastic films, laminated films, coated paper, and other flexible packaging materials.
Applicable Industries: Food, pharmaceuticals, personal care, electronics, hardware components, and any industry using flexible packaging.
What It Prints: Production dates, expiration dates, batch numbers, serial numbers, barcodes (Code128, EAN, etc.), QR codes, Data Matrix codes, logos, and graphics.
In one sentence: Thermal Transfer Overprinter = The professional tool for printing clear, durable, and scannable codes onto flexible packaging – giving every bag a reliable “ID card.”

Single-side open roll-fed packaging film is a roll of continuous packaging material with one side (typically the top) pre-opened, specifically designed for automatic bagging machines. The film feeds continuously from the roll, and the pre-opened design allows the machine to easily separate and open each bag mouth without additional air blowing or mechanical aids.
In one sentence: Ready-to-open film on a roll that keeps automatic packaging lines running smoothly – no jams, no misfeeds.
Key Advantages:
✅ Pre-opened design – bags open effortlessly, reducing jams and misfeeds
✅ Continuous roll format – matches automatic feeding mechanisms for uninterrupted operation
✅ Versatile materials – available in PE, PP, laminated films, and more
✅ Customizable – size, thickness, printing (logos, barcodes, QR codes, text), anti-static, moisture-proof, oil-proof treatments
✅ Consistent quality – uniform dimensions and thickness from batch to batch, no need to recalibrate machines
✅ High compatibility – works seamlessly with most automatic packaging equipment

Our single-side open roll-fed packaging film is designed as the “matched consumable” for the JYZN series automatic packaging machines (such as the JYZN-350gdk). Manufactured to the exact specifications of the equipment’s feeding system, it delivers seamless compatibility – smooth bag feeding, firm seals, and precise positioning – maximizing your Overall Equipment Effectiveness (OEE).
In one sentence: Single-side open roll-fed packaging film = the dedicated roll film for your automatic packaging machine. Open, feed, seal – keeping your line running at peak efficiency.
Pre-opened continuous roll bags are exactly what they sound like: bags with the mouth already opened, rolled up in a continuous roll.
Picture this: each bag’s opening is naturally separated—no rubbing, no blowing, just grab and load. Multiple bags are connected in a roll and loaded directly onto automatic packaging machines. The machine pulls one, opens it effortlessly, loads the product, and seals it—all in one smooth flow.
Regular flat bags:
Bag mouths stick together—you have to rub them open or blow air to separate them
Tend to jam or misfeed on automatic machines
Suitable for manual bagging, but not for automated lines
Pre-opened continuous roll bags:
Bag mouths are naturally separated—pull and they open
Run smoothly on automatic machines with minimal jams
Specifically designed for automatic packaging equipment
Problem #1: Your bags keep jamming on the automatic machine?
Regular bags have sticky mouths that the machine can’t open properly—leading to empty bags passing through, machine stoppages, and workers constantly on standby to clear jams.
With pre-opened continuous roll bags: The bag mouth is already separated. The machine’s opening mechanism lightly spreads it open with ease. Every bag runs through smoothly—almost zero downtime.
Problem #2: Every time you change bags, you have to recalibrate the machine for ages?
Some bags have inconsistent material and thickness from batch to batch, requiring lengthy machine re-adjustments every time.
With pre-opened continuous roll bags: We strictly control dimensions and thickness for consistent quality batch after batch. Load them up and go—no repeated adjustments needed.
Problem #3: Worried about misaligned printing on QR codes?
Regular bags might shift when reaching the sealing position, causing unstable printing or sealing alignment.
With pre-opened continuous roll bags: With standardized dimensions and precise positioning, combined with the machine’s registration system, print positions are consistently accurate—every bag, same spot.
