Side Sealing Bag Making Machine Selection Guide: Find the Right Model for Your Factory

Before choosing equipment, define your production workflow: a side sealing bag making machine converts plastic film rolls into finished bags, whereas a band sealer seals the openings of pre-made bags.

If your plant needs to manufacture bags in-house, this guide breaks down selected COSMO side sealing bag making machine models by bag style, dimensional capacity, film compatibility, and output speed, helping you shortlist a model for your factory.


What Is a Side Sealing Bag Making Machine?

A side sealing bag making machine (sometimes called a side sealing and cutting machine) feeds plastic film from a roll, seals the sides, and cuts the film into individual bags. Unlike a bottom sealing machine—which seals along the bottom edge—a side seal model forms seals along the sides of the finished bag.

Common applications include saddle and wicket bags, beverage carriers, handle bags, and water bags. Configurations such as punching units, handle devices, and gusset attachments depend on the specific model selected. Confirm which devices are included in the quotation.

How a Side Sealing Bag Making Machine Works

A side sealing bag making machine converts film rolls into finished bags through film feeding, sealing, and cutting. Additional operations and their sequence depend on the bag design and machine configuration:

  1. Film Unwinding: Plastic film unwinds from the roll and enters the machine.
  2. Film Feeding: The machine advances the film through the production line.
  3. Folding & Gussetting: Gusseted bag styles require suitable forming equipment; the setup depends on the bag design.
  4. Side Sealing & Cutting: The film is sealed and cut into individual bags.
  5. Handle Making & Punching: Depending on the model and configuration, equipment forms die-cut handles or adds loop handles, reinforcing patches, or draw tape.

Selection Tip: Production speeds are listed as published on COSMO’s product pages. Check the stated units and number of production lines before comparing models. We recommend confirming your expected output with your specific bag design and film sample before ordering.

Control features vary by model. For example, COSMO lists the following features for the SH-32-FC:

  • Servo Drive Control System: A standard servo motor allows adjustment of bag length and production speed.
  • Computer Control: Computer control manages the production process.
  • Automatic Film Feeding: Automatic film feeding is listed among the model’s features.
  • Automatic Stop Functions: The machine stops when film runs out, film feeding is blocked, or bags jam.

Check our model page for exact control features and automatic stop functions.


How to Request an Accurate Quote

Follow these five steps to define your requirements before requesting a quotation:

  1. Define the bag type: Identify the handle, wicket holes, gussets and sealing method, then shortlist the relevant models.
  2. Check dimensions: Compare bag length, width and gusset size with the selected model. Label the seal-to-seal dimension on your drawing to avoid ambiguity.
  3. Confirm film material and thickness: Provide the film type and thickness per layer where applicable; check both against the proposed configuration.
  4. Confirm production output: Ask for the expected output with your film, bag dimensions and attachments; compare output using the same units and number of production lines.
  5. Check installation requirements: Confirm the machine layout, electrical supply and compressed-air needs. The listed compressors are not included; obtain installation specifications before preparing the factory.


Comparing Quotes From Other Manufacturers

When comparing quotes across different equipment vendors, look beyond the listed purchase price and theoretical maximum speeds. Consider these critical operational factors:

  • Changeover time: how long it takes to switch bag types or film materials, and whether the change requires special tools or a technician
  • Warranty coverage and duration: whether the warranty covers parts only or both parts and labor
  • After-sales support: local service availability, response times and access to spare parts in your region
  • Installation and commissioning: on-site setup versus remote support only
  • Total cost of ownership: compressed air and electricity consumption, plus consumable parts such as sealing wires and blades, not just the listed machine price


Side Sealing Bag Making Machine FAQ

How long does a changeover between bag styles or sizes take?

Changeover time depends on the required adjustments, such as bag dimensions, film, handle punches, or gusset-forming equipment.

Ask COSMO for an estimate based on your bag specifications and whether a timed changeover demonstration is available.

What consumable parts are required for routine machine maintenance?

Wear parts and replacement intervals depend on the machine configuration and operating conditions. Ask COSMO for a recommended spare parts list for your configuration, including replacement guidance and lead times.

Can bag dimensions or handle attachments be customized beyond published specification limits?

The specification tables display our standard production ranges. If your target bag size falls outside these dimensions or requires a specialized handle attachment, submit your drawings to COSMO to confirm whether a suitable configuration is available.

Do these machines support regional voltage configurations other than 220V, 3-phase?

The published specifications for the models listed here specify 220V, 3-phase. If your factory operates under different local power grids (such as 380V or 415V, 3-phase), provide your voltage and frequency during inquiry to confirm the required electrical configuration.


Confirm Your Bag Type Before You Confirm the Order

To ensure you receive the most accurate proposal, simply send us your target bag samples or engineering drawings, film type and thickness, required output, and factory utility specs (power voltage and air supply).
