Carton sealing machine from China

A carton sealer is cheap and simple, and the costly mistake is a fixed-size model in a warehouse that ships many box sizes, where someone stops the line to reset it.

Carton sealing machine

01

What you are actually comparing.

Two quotes, one machine name

What hides inside the price
01

Fixed or adaptive

A fixed sealer is set by hand for one box size. An adaptive sealer senses each box and moves its belts and tape head itself.

02

Side belts or top and bottom belts

Side belts grip the box walls. Light, soft or tall boxes can need top and bottom belts.

03

Flap folding

Top flaps folded by an operator, or by the machine.

04

Tape heads

Tape width, knife guarding, and how easy the heads are to buy again.

02

Decode the model code.

Many sealers put the largest box in the model number. On an FXJ-5050, one listing stated a largest box 500 mm wide and 500 mm high. Measure your largest box first.

  • FXJ-5050: 50 = 500 mm width, 50 = 500 mm height.

03

Before you ask for a price.

Send these with the enquiry. Without them, any number a factory gives you is a guess dressed as a quotation.
