Shrink wrapping is generally used for packages intended for retail display. These packages are totally enclosed in high-quality polyolefin film chosen for its ability to provide a clear,sparkling finished package to be placed on a shelf. From tabletop L-Bar to high-speed automatic shrink packaging machinery, Saturn Packaging offers a wide range of shrink wrap solutions depending on your needs.
Labeling and printing can be integrated with your desired Shrink Packaging system, whether its top, bottom, side corner applications.
SEALERS THAT SUIT YOUR NEEDS
At Saturn Packaging, we offer regular and industrial grade solutions adapted to your products and level of automation. L-sealers are named for the L-shaped seal pattern which consists of an end and side seal of a package as well as the front seal of the trailing package. Generally combined with a shrink tunnel, these sealers can be affordable and versatile wrappers within a certain range of product sizes. Available in different seal sizes.
The Saturn Packaging Alpha, Kappa, StarPak, Gamma, Beta and Delta semi-automatic sealers allow for greater control over the packaging of individual products thanks to the L-bar sealing system. Our combination sealers models with integrated heat tunnel, Alpha, Kappa and StarPak are compatible with options to upgrade the equipment depending on your needs while maximizing your floor space. All three types are suited to industrial mas sproduction as well as manual packaging and can be used for sealing (L-bartechnology) as well as shrink wrapping.

Shrink tunnels play an important role regarding the appearance of the shrink package. The heater size, fan velocity, volume of air, control of the direction of the air, belt type, and tunnel length are all critical factors in the choice of a tunnel.
Saturn Packaging forced air convection shrink tunnels feature digital temperature control, high velocity blowers, automatic cool down, variable speed conveyors. Saturn Packaging offers three different models (Gamma, Beta, Delta) depending on your product size. All three models can either have the standard Teflon mesh belt conveyor or rollers or metal chain conveyor belt. The Delta model can either be built with a single chamber, double chamber or triple chamber. All three models have a complete stainless steel wash down construction option.
A shrink tunnel is a heated tunnel with a conveyor system running through the tunnel. The heat settings and conveyor speed of the shrink tunnel can be adjusted to properly heat a shrink film. The heat applied to the shrink film enables the film to tightly conform to the product within the film. Shrink tunnels are used in a variety of industries for retail packaging, food packaging, and industrial packaging.
Shrink tunnels are a great option to help increase production while offering a consistent shrink rate to all products. There are a variety of tunnels and combo sealer sets to choose from. The heat shrink wrap tunnels offered online are to accommodate all ranges of production. We also sell conveyor belts, L-Bar sealers and side sealers to work with each shrink tunnel.
Each shrink tunnel has a variety of differences including: speed, chamber dimensions, legs, control panels, and more. Below is a brief description of each tunnel we offer online. Call us for other tunnel heights and widths available.
Recommended Tunnel Settings
Shrink tunnel settings are important when setting up a new shrink tunnel. The proper settings will allow packages to obtain a consistent professional look. We will go over a brief description of each setting located on the control panel. Optimal settings differ depending on the type and thickness of shrink wrap being used.
This is the internal temperature of the tunnel. The recommended temperature will vary depending on the type of film being used and the thickness of the film. The two most common types of centerfold shrink film used with shrink tunnels are 75 gauge PVC or Polyolefin shrink film. An optimal setting for the PVC shrink film is between 210 – 230 degrees Fahrenheit. For a 75 gauge polyolefin film the optimal setting is between 260 – 280 degrees Fahrenheit.
The conveyor speed is often more important than the temperature setting. Many beginners dramatically increase temperature settings when slower conveyor speeds are needed. Setting a new shrink tunnel to the lower end of the recommended heat setting with a slower conveyor speed (1.5-3) will increase the life of the tunnel. If higher conveyor speeds are needed slowly increase temp. settings until all dog ears and wrinkles are out of the shrink film.
Shrink Bundling, also known as sleeve wrapping, is generally used for packages intended for storage, where appearance is not the primary concern. The bundles are wrapped in polyethylene film to protect the goods while being shipped and handled as they are puncture resistant and durable. The “bulls-eye” method is the most popular type of shrink bundling where the ends are left open.
Saturn Packaging offers a variety of Shrink Bundlers that can be custom designed to meet your specific requirements with different infeed and collation options (inline product pushers, multi-lane infeeds).
The main bundling steps are:
1. Infeed conveying
2. Collating/ grouping (optional, as some products are individually sleeve wrapped)
6. Outfeed conveying
The products travel through a polyethylene curtain to create a film sleeve. When passed through the heat tunnel, the sleeve shrinks tightly producing the bull's eye closure style.
Labeling and printing can be integrated with your desired Shrink Packaging system whether its top, bottom, side corner applications.
Once your products are cased and placed on the pallets, a stretch wrapper is needed to complete the packaging job. This piece of equipment is important when shipping numerous items on a pallet to safely stabilize them.
A wide range of ink jet coding, automatic labelling and marking products is available. These systems can be integrated with any Saturn Packaging Equipment.
Saturn Packaging also offers a wide range of third party labelers for different product size and output speed. Whether its side, bottom, top labelling, Saturn Packaging can offer the product you need.

Flow wrapping is typically a horizontal process that wraps a product in a clear or printed polypropylene film. This system generally gets the film fitted around the product to minimize the shift in the package. This application is mostly used in the food industry.
Saturn Packaging takes pride in designing and manufacturing custom systems depending on your needs. Whether it’s a pick and place system, glass cutting, chocolate cutting, former slabber, Saturn Packaging is up for the challenge on developing your unique solution.
