Optional Value

We also provide a range of optional upgrades for the machines. Let's find out what extra value you may need.

Kissing conveyor

Kissing conveyor

The distance between the front and rear conveyor belt can get closer for packing small products. When sealing happen, the rear conveyor will pull back for sealing bar to go downward.

Conveyor speed control

Conveyor speed control

This option offer user can adjust the front and rear conveyor speed on L-bar sealer. When dealing with unstable or slippery surface product (such as bottles and a pile of books), the inertia of conveyor may affect the product alignment. Slow down the conveyor speed can improve this problem.

Stainless steel version

Stainless steel version

Stainless steel machine are available allow the machine to be working stably under high moisture and low temperature working condition.

Eye-mark sensor

Eye-mark sensor

To use with color printed films for ensure preset bag length per pack.

Automatic grouping and feeding device

Automatic grouping and feeding

Feeding devices with grouping function are specially designed to feed products to form a multi packing. Several products can drive together on the same time to prohibit misalignment happen. Packaging quality is improved because of this. It can increase production speed compare to feed multi products by hand. Connecting to the existing production line can accomplish a fully automatic production.

Flight bar conveyor

Flight bar conveyor

A guide rail pushing system is employed to pushing product in muti-packs format. Depends on products height and shape, different guide rail pushing systems are available.

Finger conveyor

Finger conveyor (lug conveyor)

Finger conveyor contains quick change flight lugs with stainless steel surface. With product guide rail, it is mostly used for driving a cluster to fit a wide range of products. Program connected to subsequent shrink wrapper and missing products detection is provided. Tailor made in different specifications are available.

Automatic Feeder
