Automatic 3 Side Seal Bag Making Machine | PLC & Servo Control

If you buy packaging equipment for export markets, a 3 side seal bag making machine is often one of the first machines on your shortlist. It turns film rolls into flat, sealed bags for snacks, rice, pet food, frozen meat and many other products. The machine looks simple, but small details decide your results: seal quality, bag length accuracy, film waste and downtime.

This guide explains how an automatic 3 side seal bag making machine works, which features matter and what to check before you buy. Jiangyin Xinghong Packaging Machinery Co., Ltd. was founded in 2016. We build intelligent bag making equipment in a 10,000 square meter factory in Gushan Town, Jiangyin, Jiangsu, China. Our X6003 Side Seal Bag Making Machine is made for this bag type.

Use this article to compare options, prepare a clear inquiry and avoid common buying mistakes.

What Is an Automatic 3 Side Seal Bag Making Machine?

A 3 side seal bag making machine forms flat bags from plastic or laminated film. It seals three edges, cuts each bag to length and leaves the fourth edge open. Your customer fills the bag through the open side and seals it on a packing line.

The word “automatic” means the machine runs the full cycle without manual handling. It unwinds the film, controls tension, seals, cuts and counts the bags. The operator loads the film roll, sets the bag length and watches the output.

You may also see this equipment called a 3 side seal pouch making machine, a three-side sealing bag machine or a flat pouch making machine. These names describe the same basic machine type.

Typical users include:

•      Bag converters and packaging factories

•      Food, snack and pet food brands

•      Distributors who supply bag making equipment to local customers

•      OEM buyers, engineering companies and project contractors

Key Features of the X600 3 Side Seal Bag Making Machine

The X600 is the three-side seal model in the Xinghong range. These are the features listed for our machines:

•      Dedicated 3 side seal design. The X600 is built for three-side sealed bags.

•      Panasonic PLC pulse control. This supports high bag length accuracy, a low failure rate and stable operation.

•      Bus motion control. A Xinye motion controller runs on an Ethernet bus. It computes fast, is easy to install and maintain, and allows custom functions to be added.

•      Remote function. Our engineers can connect to the machine remotely and help solve problems on site.

•      In-house CNC parts. We manufacture all key components on our own CNC machine tools.

•      Customization. We design the machine around your bag type and production needs.

For a buyer, these points mean fewer stoppages, easier troubleshooting and a machine that matches your actual bag, not a generic standard.

PLC and Servo Control System for Accurate Bag Length

Why bag length accuracy matters

Every bag is cut at a set length. If the length drifts, you waste film, get poor seals or cut through printed artwork. Accurate control is even more important when you run printed film or pay a high price for laminated material.

How the control system works

The X600 uses Panasonic PLC pulse control to manage bag length. A Xinye motion controller then coordinates the machine actions through an Ethernet bus. A bus system reduces wiring, makes diagnosis faster and leaves room to expand the machine later.

Before you order, ask our engineers to confirm the exact drive configuration for your machine, including the motor type. This makes sure your quotation matches your production target.

Technical Specifications of the X600 Bag Making Machine

The table below shows what we can confirm for the X600. Bag size, speed and power depend on your project, so we confirm them in the quotation.

To get an exact specification, send us your bag drawing, film structure and target output per minute.

How Does a 3 Side Seal Pouch Making Machine Work?

The exact layout depends on the configuration, but a 3 side seal pouch making machine follows these main steps:

1.     Unwinding. The machine holds the film roll and feeds the film forward.

2.     Tension control. Sensors and rollers keep the film flat and steady.

3.     Film guiding. The film is guided into position for sealing.

4.     Heat sealing. Heated sealing bars form the side and bottom seals.

5.     Cooling and cutting. The seals set and the machine cuts each bag to the set length.

6.     Counting and output. Finished bags are counted and sent to the collection area.

Seal temperature, pressure and time must match the film. Good machine design lets the operator adjust these settings quickly when the film changes.

Types of Bags You Can Make with the X600

The X600 makes 3 side seal bags. This flat bag style is popular for dry food, frozen food, powders and many industrial products.

Some projects need a different bag style. Xinghong also builds other bag making machines. OurCenter Seal Bag Making Machine makes center-sealed bags, and ourStandup Bag Making Machine makes stand-up pouches. Our product range also covers four-side seal, zipper and spouted bags. Tell us your bag style and we will recommend the right model.

Suitable Materials: PE, PET/PE, Aluminum Foil and Laminated Film

Buyers use a 3 side seal bag making machine with many film structures. Common examples include:

•      PE film for general-purpose bags

•      PET/PE laminated film for food bags

•      Aluminum foil and aluminum-plastic composite film for barrier packaging

•      Other laminated films for high-temperature cooking bags and vacuum bags

Film structure and thickness change the sealing settings, so each project needs a short technical check. Send us the film structure, thickness and, if possible, a sample roll. We will confirm the setup with you before production.

Applications: Nut, Rice, Cat Food, Fresh Meat and Cooking Bags

Our machines serve a wide range of bag types. The applications below are listed on our website:

•      Food bags: nut bags, bags of rice, fresh meat bags and live fish bags

•      Pet and animal products: cat food bags and feed bags

•      Heat and barrier packaging: high-temperature cooking bags, aluminum foil bags, aluminum-plastic composite bags and vacuum cooling bags

Each product has its own needs. Fresh meat and live fish bags need reliable seals and suitable film. Cooking bags need film that tolerates heat. Rice and feed bags need strong seals for heavier fill weights. Tell us your product and fill weight, and we will review the machine setup with that in mind.

3 Side Seal vs 4 Side Seal vs Center Seal Bag Machines: Which Is Better?

No single bag style is better for every product. The right choice depends on what you pack and how you fill it. This table gives a simple comparison:

If your product fills from the top and you want a flat bag with a good printing area, a 3 side seal bag is usually a strong choice. If you need a bag that stands on a shelf, look at stand-up pouches instead. Our team can help you compare styles for your product.

How to Choose the Right 3 Side Seal Bag Making Machine

Use this checklist when you compare suppliers:

1.     Define your bag. Write down the size range, film and monthly volume.

2.     Ask about control. Check the PLC brand, the motion control system and how the machine corrects bag length.

3.     Check key parts. Ask which parts the factory makes itself and which it buys.

4.     Ask for a test. Request a video of the machine running a bag similar to yours.

5.     Review support. Confirm remote support, response time and spare parts supply.

6.     Confirm paperwork. Ask for the manual, the electrical drawing and any documents your market requires.

7.     Plan for growth. Choose a machine that can handle your next product, not only today’s order.

A reliable supplier answers these questions clearly. If answers are vague, treat that as a warning sign.
