Shrink Bundler Information

Shrink bundlers are used with two single-wound (flat) film rolls to wrap and unitize multiple products together. Shrink bundlers use a heated sealing bar to seal and cut the single wound bundling film. The single seal creates two open sides on each end of the product. The open ends are often referred to as bulls-eyes.

A shrink bundler encloses the product(s) in the shrink film, but heat still needs to be applied. Some shrink bundlers are all-in-one systems that offer the bundler and heat tunnel as one unit. Other bundlers are only the bundle sealers and require a shrink tunnel to heat the film.

Shrink bundlers have large openings for stacked cases, bottles, and other heavy products. The air operated opening closes to make a seal after the product passes. The seals are thicker and stronger than other wire shrink sealers.

After the seal is complete, a conveyor transports the product(s) into the shrink tunnel. The conveyor belt features stronger motors for moving heavier products. All shrink bundlers should feature an easily accessible E-stop and additional safety features to maintain workplace safety standards.

Bundling Tunnel Information

Shrink bundling tunnels are made to handle more heat and heavier products than standard shrink tunnels. Thicker shrink wrapping materials require longer tunnel dwell times at higher temperatures.

Shrink bundling tunnels need larger heater banks to maintain hotter temperatures. Standard heat tunnels come with 7-10 kilowatt heaters while bundling tunnels come with larger 12-15 kilowatt heaters to produce more heat.

Inside recirculating shrink tunnels, blowers are used to evenly distribute the heat from the heater banks. In standard shrink tunnels can offer anywhere from 1 – 3 blowers depending on the size of the tunnel. Due to the size of most bundling tunnels, a minimum of at least 3 blowers is used. The multiple blowers can be adjusted to reach the right air velocity as the products continue through the conveyor.

One of the last differences between shrink bundling tunnels and retail shrink tunnels is the size. Due to the heating and cooling time needed to properly shrink a polyethylene bundling film, the tunnels have to be large. Most bundling tunnels have a 12” – 20” height opening to fit larger bottles and cased products. The length of bundling tunnels is longer than smaller retail tunnels. The thicker material needs more time to heat and cool, a longer tunnel ensures longer dwell times and faster conveyor speeds.
