SLR Shrink Wrap Bundler for Unstable Products
The SLR is a medium-speed welding-bar shrink wrap bundler built for unstable product: tall bottles, odd-shaped jars and cans, spice containers, pump bottles, RX vials, and aerosols that will not stand through a standard SIM collation.
It groups product horizontally, on its base, with a high product stabilizer. Single, double, or triple track. Straight or 90° side infeed. About 22 packs per minute on a single track; dual/triple track takes output into the 40–50 packs/min range. No corrugated pad or tray is required unless you want one.
How the SLR keeps unstable product upright
- Side infeed. Product arrives standing, straight or around a 90° curve.
- Horizontal collation. Rows are built on the base — not lifted or tumbled — into the pack pattern on the HMI.
- High product stabilizer. Guides and a stabilizer keep tall bottles from rocking while the pusher fires.
- Welding bar. Two film rolls form a curtain. The bar seals top and bottom, cuts, and remakes the curtain.
- Indexed transfer onto the tunnel. On frames such as the 82SLR, a dual pusher and intermittent tunnel belt take the sleeve without dumping a tall pack.
- Shrink + cool. Heat tightens the sleeve; bullseyes on the ends; the pack is stackable.
That transfer step is why a standard SIM fails on the same bottle: the pack is stable in film, not on the infeed.
Why plants choose the SLR
It is built for tippy product, not adapted after the fact. Stabilizer, horizontal collation, and (on larger frames) dual pusher + indexed tunnel belt are the point of the model.
Film-only when a tray is wasted board. Many grocery and pharma packs do not need a pad if the sleeve is formed while the bottle is still standing.
Speed you can staff. ~22 ppm single track; dual/triple track when the line is faster. Welding-bar cost and footprint vs. a CMOS overlap machine.
Aerosol-ready. Optional tunnel features for spray cans.
Compact stainless line. Straight or curved infeed, 90° or inline outfeed, Allen-Bradley PLC/HMI on Holland-supplied systems.

Popular Options:
Yes. If most of the work is trays, look at SLN or SIT first.
Yes, with the aerosol tunnel option.
SLO is for oval bottles that must be rotated before wrapping. SLR is for stability — product that falls over. A bottle can be both; we spec from a sample.
SIM assumes the container is stable enough to accumulate and group. SLR adds horizontal collation, a stabilizer, and (on larger frames) a gentler transfer onto the tunnel so tall packs do not dump.
About 22 packs per minute on a single track. Dual track is around 40 ppm; triple track is rated up to about 50 ppm, depending on bottle and pack size.
No. It is built to sleeve without a pad or tray. Add a pad (SLC) only if pallet strength requires it.
Anything that tips during collation or transfer: tall bottles, small-footprint jars, top-heavy pumps, spice containers, RX bottles, aerosols. If it will not stand through a SIM, it is an SLR job.
