There are various aspects to consider while guaranteeing the safety of your final goods before delivery or sale. If you need to keep many goods from being touched, heat tunnel shrink wrap is the only option.
Shrink wrapping has gained favor as a product protection method. Wrapping most items costs pennies, making it a cheap alternative. It resists scratches and scuffs despite heavy use. It works. Easy to pack multiple items into a single box.
How Does It Work?
Shrink wrapping is easy. A hot knife seals and trims the extra shrink wrap before applying heat to shrink it down. Various tools are available now to help in this process.
Hand-Shrinkage Wrapping Machine
The smallest shrink wrap tunnel machine is an I-Bar Sealer. The I-Bar sealer uses a shrink film roll, a heating element, and a “hot-knife” wire on a hinged arm. A heat gun may also be supplied.
Again, the steps are simple. Seal the thing in the shrink film. Wrap the I-Bar around the shrink film and clamp it. The heated wire melts and cuts the wrap at the same time. Then shrink the wrap to its desired size using a heat gun. These shrink wrappers are great for small enterprises. It just takes a minute to seal and package finished shipments.
Combo Shrink-Wrap Machines
Combination machines may accomplish two things at once, as their name implies. Unlike all-in-ones, combo machines employ an L-Bar sealer and a heat tunnel to combine sealing and shrinking.
A combination machine’s L-Bar sealer may be used to seal items manually. Then a heat tunnel shrinks it. An overhead roller conveyor circulates warm air through the heat tunnel.
This machine is built for high-volume manufacturing. Consider a production process. A single person seals and feeds a package into the heat tunnel. The items may be packaged into shipping boxes while another person stands at the heat tunnel’s other end. Spiral-wrapped packages are often placed onto a second conveyor for delivery.
Automated machines do both sealing and shrinking. A special chamber powers the hot wire cutter and the heat gun. These shrink wrap tunnel machines employ an L-Bar sealer to seal the film on both sides. Fans circulate heated air through an enclosed chamber, sealing the item and shrinking the film with a hot knife wire. The complete procedure takes between 5 and 10 seconds for each item.
Comparatively, utilizing a heat gun to seal and compress containers saves time. Even on the highest setting, a heat cycle may wrap several hundred packages every hour.
Automated Shrink-Wrapping Machine
Adding an automated machine to a combination machine speeds up the process. Automated shrink wrap machines need no human involvement; just feed the items into the infeed conveyor and wait for the wrapped and shrunk products to emerge.
Automatic shrink wraps frequently incorporate an automated loading and unloading mechanism. These gadgets make more sense in a fully automated packaging process.
You may use heat tunnel shrink wrap to wrap card packs for clients or manufacture high-volume products. Volume and cost are essential factors to consider when selecting a solution. A manual shrink wrap machine might cost as low as a few hundred dollars.
