Two clip sizes cover almost every bag closing job in a produce pack house: 506
and 711. They are not interchangeable, and using the smaller one where the larger
belongs is the most common cause of bags opening in transit.
The short version
| 506 clips | 711 clips | |
|---|---|---|
| Profile | Smaller, standard | Larger, standard |
| Holds | Net bags up to about 5 kg | Thick net bags, heavy loads |
| Typical material | Extruded PE mesh, poly bags | Woven mesh, thick film, casings |
| Closers | 506 manual and pneumatic heads | 711 manual and electric clippers |
If your bag is extruded mesh and the finished weight is under about 5 kg, 506 is
almost always correct. If the mesh is woven, the film is thick, or the bag
carries more than 5 kg, use 711.
Why the wrong size fails quietly
A 506 clip on a thick woven bag closes — the machine does not jam and the bag
looks fine. What has actually happened is that the clip has not been crimped
around the full bundle of material, so it holds by friction alone. The bag
survives the packing line and the pallet, then opens in a container in transit.
If you are between sizes, the safe move is to step up to 711. The clip costs
slightly more; an opened bag costs a customer.
Matching clips to your machine
Both profiles are available for the manual and powered clippers in the same
range. Keeping the clip profile and the die in the machine matched is what
delivers a consistent crimp — a 506 die will not form a 711 clip properly even
if the clip physically fits in the channel.
Ordering
Clips ship carton-packed for export. Tell us the bag you are closing and we will
confirm the profile, the die you need and the number of clips per carton so you
are not reordering mid-season.
