Bag Sealing Machine Selection Guides

Choose a bag sealer by film structure, seam length and package geometry. Compare handheld jaws, impulse sealers and continuous rotary sealing.

How to Choose a Bag Sealing Machine

Use bag material, working seam length and package access to choose between bench impulse sealers, handheld jaws and a rotary sealer.

Foil laminates

Check the sealant layer of a foil laminate pouch, choose a jaw length and use an actual bag test before selecting a FABLE FDR sealer.

Flat poly bags

Choose a PFS bench impulse sealer for compatible flat poly bags, with practical checks for jaw length, cooling and electrical supply.

Wide bag openings

Measure the complete bag opening and choose an HI long-length hand sealer when a short impulse bar cannot cover the seam in one pass.

Bulky packages

Evaluate ROS-25 for accessible continuous seams on large packages. Check wheel access, material, seam support and production conditions.

Machine comparison

Compare FABLE FDR, FKR and FIS by published seal width, jaw length and control layout, then test the actual packaging material.

Coated paper

Learn when lined kraft or coated paper is a heat-sealing candidate, and when adhesive or another closure is the appropriate shortlist.

Gussets and multilayer seams

Qualify gussets and overlap zones separately. Select jaw or rotary geometry by access, then test weak points across the seam.

Troubleshooting

Troubleshoot weak bag seals, burn-through and wrinkles by isolating material, contact and process conditions before replacing a machine.

Sample tests and RFQs

Build a sample-sealing and wholesale acceptance checklist covering the actual bag, test setup, repeatability, strength and leak requirements.
