One of the most popular types of shrink wrapping machines are L-bar sealers. This is because they are fast, convenient and get the job done in a fraction the time it takes an I-bar sealer. Most people, once they begin looking into purchasing a machine, are amazed to discover just how many uses a shrink wrap machine has. The primary purpose of a shrink wrap machine is to package products. Most people think of DVDs or CDs when the word shrink wrap is mentioned. DVDs and CDs are packaged by shrink wrap machines, but shrink wrap machines can also be used to package food, bundle paper together, sort objects and much more. L-bar shrink wrap machines are available in several different models and sizes. Entry level L-bar sealers are typically used on a countertop or table. These models are convenient and lightweight. The actual shrinking of the film is often done using a heat gun, rather than a heat tunnel. Mid-size L-bar sealers are usually floor models. This means they have their own built-in legs and are designed to stand on their own. These types of shrink wrap machines are popular for many businesses. The heat for the shrinking process is usually some sort of heat tunnel. A heat gun could be used, but would be a bottleneck. Heat tunnels dramatically speed up the shrink wrap process. On the high end, L-bar shrink wrap machines can be used to package hundreds to thousands of products a day. These types of machines are used by factories for bulk packaging. High-volume L-bar sealers feature magnetic locks, arms that automatically come down for sealing, conveyors and custom programming. While the range of L-bar sealers varies a lot, the end result looks the same. The biggest difference between low, medium and high-volume shrink wrappers is the amount of products they can package in an hour, day or month. Most shrink wrap machines are universally capable of using PVC and Polyolefin shrink film. It is very important, before making a purchase, to analyze current needs and future needs.
