Automatic Center Seal Bag Making Machine | PLC Control – H600

Buyers who compare a center seal bag making machine usually ask the same questions. How fast is it? How accurate is the bag length? Can it run my film? Who supports it after shipping? This guide answers them for the H600 automatic center seal bag making machine from Jiangyin Xinghong Packaging Machinery Co., Ltd.

Xinghong has built intelligent bag-making equipment in Jiangyin, China, since 2016. The H600 is its mid seal model. It combines Panasonic PLC pulse control, Xinye bus motion control, and remote diagnosis in one machine. Below, you will find how it works, its specifications, suitable films and bags, and how center seal compares with three side seal and four side seal formats.

What Is an Automatic Center Seal Bag Making Machine?

An automatic center seal bag making machine turns a roll of heat-sealable film into finished bags. It folds the film, seals a seam down the back, then seals and cuts across the film to form each bag. Each finished bag has one longitudinal seal and two transverse seals.

Suppliers use several names for this equipment: center seal bag machine, back seal machine, middle seal machine, and mid seal machine. Xinghong lists the H600 as its Mid Seal Machine. When you compare quotations, check the bag structure, not the name.

This format suits candy, nuts, frozen food, and small consumer goods. Its simple structure also supports high-speed production.

How Does a Center Seal (Back Seal) Bag Making Machine Work?

The H600 follows five stages. Each stage affects bag quality, so check all five when you evaluate any center seal bag making machine.

1.     Unwinding. The film roll feeds through a regular unwinding structure. You can upgrade to servo-driven unwinding.

2.     Folding. The machine folds the film in the middle or at the edge.

3.     Longitudinal (L) sealing and cooling. The machine seals the back seam and cools it.

4.     Transverse (T) sealing. Sealing runs under high pressure and low temperature. Many laminated films need this balance to seal firmly without damage.

5.     Cutting and collecting. Choose double cutting, CCD cutting, or die cutting. The machine also supports automatic collecting and the inspection and removal of faulty bags.

Servo motors power the main drive (one motor) and the film feed (two motors). A Panasonic PLC controls bag length.

What Types of Bags Can the H600 Center Seal Machine Make?

The H600 makes center seal (middle-seal) bags. Its listed working range is:

•        Bag width: 80–600 mm

•        Bag length: 80–500 mm

•        Machine speed: 200 CPM

Real output depends on bag size, film structure, and seal design. Send us your target bag size and daily volume, and our engineers will confirm a realistic speed.

The H600 focuses on one bag structure. Xinghong builds separate machines for other formats. The X600 handles three side seal bags, and the D600 is astand up pouch machine. The range also includes four side seal, zipper, and nozzle bag machines. If your project needs more than one format, tell us and we will plan the right combination.

Key Features of the H600 Center Seal Bag Making Machine

These features matter most to factory buyers:

•        High speed. The machine is rated at 200 CPM.

•        Wide bag range. It covers 80–600 mm in width and 80–500 mm in length.

•        Servo drive. One servo motor runs the main drive, and two run the film feed.

•        Three control layers. Panasonic PLC control, bus control, and remote debugging work together.

•        Cutting options. Choose double cut, CCD cut, or die cut.

•        Non-stop roll change (optional). A film storage of 50 m keeps the machine running during a roll change.

•        Custom width. Xinghong can adjust the machine width to your production plan.

•        In-house machining. Xinghong makes the key components on its own CNC machine tools.

Panasonic PLC Pulse Control for High-Precision Bag Length

Bag length errors waste film and cause rejected shipments. The H600 uses Panasonic PLC pulse control to manage length. According to Xinghong, this system delivers high bag-length precision, a low failure rate, and high reliability.

On your production line, that means:

•        More consistent bag length from roll to roll

•        Less film scrap from cutting errors

•        Fewer unplanned stops

•        Simple parameter adjustment for your operators and electricians

If you run printed film, ask about the optional CCD cut. CCD is a visual positioning device that controls the cutting position precisely.

Xinye Bus Motion Controller: Faster, Easier Operation and Maintenance

The H600 pairs its PLC with a Xinye motion controller connected by an Ethernet bus. Xinghong lists the benefits as fast computation, convenient installation and maintenance, simple operation, and strong expansion capability. The system also makes it easy to add custom functions.

For buyers, this design offers two practical advantages:

•        Easier upgrades. You can add functions later without replacing the machine.

•        Faster servicing. Bus control usually reduces wiring compared with point-to-point systems, so technicians trace faults faster.

Remote Monitoring and Online Support for Your Bag Making Machine

Service is a top concern when you import machinery from China. Xinghong addresses it with remote tools built into every machine:

•        Remote viewing. Engineers can check the software running status of the machine.

•        Remote debugging. The team connects to your device and helps solve problems on site.

•        Video and phone support. Xinghong offers service 24 hours a day.

•        Factory inspection and remote detection. The team checks equipment before shipment and offers remote detection with solutions afterward.

A stable internet connection at your factory makes remote support faster. Ask our team how to set it up before delivery.

H600 Center Seal Bag Making Machine Technical Specifications

The table below lists the published H600 data. Options are marked.

Please send your local voltage, film structure, and target bag size when you inquire. We will confirm the final configuration in your quotation.

Suitable Materials: Laminated Film, Aluminum Foil, PE, BOPP and More

The H600 works with heat-sealable flexible films. Xinghong machines commonly process these structures:

•        PET/PE and PET/CPP laminates

•        OPP/CPP and BOPP/CPP laminates

•        PE films

•        Aluminum foil laminates and aluminum-plastic composite films

•        Nylon laminates

Every film seals differently. Thickness, sealant layer, and surface slip all change the result. To avoid surprises, send these details before you order:

•        Film structure and thickness

•        Roll width and maximum roll diameter

•        Bag size and seal width

•        Print registration marks, if any

Xinghong can also arrange factory visits and product trials in Jiangyin so you can see your film run on the machine.

Center Seal Bag Applications: Nuts, Rice, Cat Food, Feed, Fresh Meat and More

Xinghong lists a wide range of bag applications on its website. The center seal format fits these product groups:

•        Snacks and dry food: candy and nuts

•        Grains: rice bags

•        Pet food and feed: cat food and feed bags

•        Fresh and frozen food: fresh meat bags and frozen food

•        Special packs: aluminum foil bags, aluminum-plastic composite bags, high-temperature cooking bags, and vacuum cooling bags

Each product needs the right film barrier and seal strength. Tell us your product, filling method, and shelf-life target. We will help you choose a suitable structure and machine setup.

Center Seal vs. Three Side Seal vs. Four Side Seal Bags: Which Should You Choose?

Start with your product and your filling line. Then match the bag format. This table summarizes the main differences:

Choose a center seal bag machine when you want a simple pillow-style bag at high speed. Choose a three side sealing machine when you need a flat pouch with a clean edge, such as a sachet. See our3 side seal pouch making machine page for the X600 details. Choose a 4 side seal bag machine for flat packs that need full edge sealing, such as wet wipes or single-dose sachets.

Many buyers run more than one format. Xinghong builds all three, plus stand up, zipper, and nozzle bag machines, so you can source from one supplier.
