Bag Making Machines: Bottom & Side Seal

About Bag Making Machines: Bottom & Side Seal

Bag making machines seal and cut plastic film into finished bags — bottom-seal for T-shirt/garbage bags and side-seal for pouches, mailers and retail packs. CECLE supplies 4 machines for LDPE, HDPE, PP and biodegradable films. Selection depends on bag style, material and output.

How to Choose

  • Bag style/seal — bottom seal (T-shirt, garbage) vs. side seal (pouches, mailers).
  • Film material — HDPE, LDPE, PP, OPP/CPP or biodegradable/PLA compatibility.
  • Output speed — cycles/min and lanes; bottom seal often faster for heavy runs.
  • Bag features — handle punch, zipper, drawtape, print/embossing modules.
  • Changeover and waste — setup time, scrap, tension control for mixed batches.

FAQ

Q: Should I choose bottom-seal or side-seal bag making?
A: Bottom seal suits T-shirt, garbage and heavy load-bearing bags on HDPE/LDPE with high speed; side seal suits courier pouches, garment and retail bags on OPP/CPP needing clarity. Match the seal to your bag geometry and film.

Q: Can one machine make both T-shirt bags and bags-on-roll?
A: Generally no — T-shirt bags need bottom sealing with handle cutting, while bags-on-roll need perforation and rewinding. Most lines are dedicated to one format; modular changeover exists but dedicated lines give better ROI at scale.

Q: Need a bag machine for your film and style?
A: Contact CECLE with your bag type, film and target output so we can recommend seal type and lanes, plus lead time and a quote.
