Product Advantages
The L-bar section leaves a straight seal line, which is useful for square cartons and printed packs.
Chain-stick conveying moves the box through the tunnel while the fan sends hot air around the corners.
Adjustable sealing and tunnel temperature help test POF, PE, PVC or PP film with different box weights.
BSE tunnel width can be selected by carton width and height instead of using one fixed chamber size.
Open control positions let operators watch film feed, seal pressure and the exit shape during sample work.
Main Applications
Box Shrink Wrapping Machine is used for tea boxes, food cartons, stationery cases, toy packs, small appliance boxes and promotional box sets.
It works when a product needs a closed film skin for dust blocking, grouped handling or shelf display.
Cartons with glossy printing should be tested with the display face away from the seam.
Quality Check
We check the seal line, four corner shrink, film holes and cooled package shape.
The largest and smallest box samples are run before the final tunnel setting is noted.
The accepted sample can be kept with the machine file before export packing.
