In today&#;s market, customers looking for an automated L-sealer have many vendors to choose from at a variety of different price points. First and foremost, is to ensure that the product to be wrapped fits within the size specifications for an automated L-sealer. Once you have validated with your vendor that the product is within the size specifications for the machine, here are a couple of points to consider:
Since L-sealers can be used in a variety of applications, it&#;s important to consider the usage. Will you be running the machine 2 to 3 shifts a day for 5 to 7 days a week? If so, look for a more robust design in the machine. Machines at lower price points are not designed to handle the stress of continual use and will need to be replaced or maintained more often than a robust machine.
Another factor to consider is the application speed. Not all L-sealers are the same and some can perform at higher speeds more consistently than others. Working with your machine vendors to understand their L-sealer capabilities will help you to make the best choice when selecting the machine.
Also make sure to know what the top speed is the machine can run, and still consistently provide a good seal. Purchasing a machine that cannot sustain the standard speed of your application will not maximize the lines operational efficiency and may create unexpected downtime in order to service the machine.
Many L-sealers at a lower price point are not manufactured in the U.S. and as a result it is challenging to get parts and service for the machines. This may not be an issue if the usage on the machine is low, but if downtime is associated with a high cost, choosing a machine that does not have local service or service parts are not manufactured within US, this could be more important than the initial investment
Once you have validated that your product will run on an automated L-sealer, next steps to consider are usage, speed, and availability of local service. All of these are key factors in evaluating the various L-Sealers on the market and will help you find the best fit for your application.

In today's fast-paced business environments, efficient and cost-effective packaging solutions are essential. An excellent way to achieve this is by incorporating an automatic L-bar sealer into your production. This automated machine provides a range of benefits, including increased productivity and efficiency, versatile packaging options, precise and high-quality seals, and reduced labor costs.
An automatic L-bar sealer is a packaging machine that seals and wraps products in a variety of materials, including shrink film, using a heated sealing bar that creates a seal around the product. The machine automatically feeds seals and cuts the film, making it a fast and efficient way to package products. It is called an L-bar sealer because the heated sealing bar has an &#;L&#; shape, which allows it to wrap around the product's edges, creating a secure seal.
There are two categories of seal bars: hot wire seal bars and hot knife wire seal bars.
This type of bar seal uses a heated wire to cut and join the surfaces of the film together with a molten edge bead, creating a precise and high-quality seal. The hot wire melts the edges of the film to form a strong bond that keeps the product securely wrapped during transportation and storage.

Unlike the hot wire seal bar that cuts through the film, the hot knife seal bar melts the film to create a strong, continuous seal without any edges. This can be particularly useful when packaging products that require an airtight seal, as it helps to prevent any air from entering or escaping the package. Additionally, the hot knife seal bar can be covered with non-stick materials to prevent sticking to the hot tooling.
A perforated roller is an optional add-on for an L-Bar Sealer that allows air to vent out while the product is passing through the heat shrink tunnel. This helps prevent air bubbles from forming, which can cause the packaging to look unprofessional or even cause damage to the product inside. It is important to note that a specific type of film is needed to use this add-on and not all films are compatible with perforated rollers, so it is recommended to consult with a film expert before using one.
A selvage rewinder is another add-on component for an L-Bar Sealer that is designed to spool the excess film that is not used for the finished product. This rewinding process keeps the production area clean and organized and can also help reduce the amount of waste generated during the packaging process. The selvage rewinder can be located either internally or externally to the L-Bar Sealer, depending on the specific design of the machine.

If you are considering purchasing an automatic L-Bar Sealer, you may also require certain upstream and downstream equipment to ensure a smooth production line. It's worth noting that the list provided below is not comprehensive and there may be additional equipment that could enhance your operation.
The L-bar sealer is an efficient piece of equipment for manufacturers looking for a fast yet cost-effective packaging solution. These machines use a seal bar shaped like an "L" to streamline the packaging process by sealing and forming the top of the next package. L-bar sealers create crisply wrapped packages and bundles for a variety of products, including irregularly shaped items, and can wrap a group of products together.
