L-Type vs Reciprocating Sealing Machine
Which shrink packaging machine is right for your production? This guide compares the two most popular machine types across speed, seal quality, applications, and cost.
Quick Answer
Choose an L-type sealer if you package boxed products, need strong vertical seals, or work with irregular shapes (40-45 bags/min). Choose a reciprocating sealer if you need high speed (80-120 packs/min) for flat products like cards, books, or food items. Both require a shrink tunnel for final film shrinking.
