An automatic L sealer is a packaging machine with multiple functions that can package several kinds of products. It comes in two main types: the cutter type and the no cutter type. The no cutter type is also called the round corner L sealer because it shapes the corners into round edges. It is ideal for businesses that want to achieve a softer look for their packaging. On the other hand, the cutter type has sharp cutters that make straight cuts on the film material to seal the edges of the packages straight. The automatic L sealer cutter is widely used and is preferable for sealing boxes or trays.
Another way to differentiate an L sealer machine is between the single and double side sealers. As the name implies, a single sealer only seals one side of the package, while a dual establishes corners of the package. Many manufacturers make single-sided sealers with automatic and semi-automatic features. Double-sided sealers are prevalent in the food industry because they hold the products tightly from both sides.
As mentioned earlier, an I sealer can be either automatic or semi-automatic. Both types perform the same function, but the automatic one does it more quickly and better. An automatic I sealer produces more than a hundred products per hour, while a semi-automatic machine can produce 50 to 100 products per hour. Automatic I sealers have a conveyor belt that moves the product into the machine, which then vertically or horizontally seals it. The sealer may or may not cut the product. Semi-automatic I sealers require manual handling before sealing.
Finally, box sealing machines differ from the type of product they are made to process. A box sealer machine, for example, would be automatic L box sealers. Similar to the L sealer, a box sealer would use a top or bottom tap to seal the box. Other types include display, intermediate, and web-seal box machines.
Automatic L sealers perform different sealing functions depending on the specifications. Here are some specifications that buyers will find when looking for the sealers.
Regular maintenance of the automatic L sealer helps it perform its tasks efficiently and prolongs its life. Here are some maintenance tips:
Automatic L sealers are suitable for packaging products in industries like food and beverage, pharmaceutical, cosmetic, hardware and tools, textiles, daily necessities, and media and entertainment, among others.
Food and beverage packaging:
Food manufacturing and processing companies use automatic L sealers to package their products, such as meat, poultry, cheese, bakery items, snacks, and vegetables. The sealers create tamper-proof, airtight packages that help extend the shelf life of perishable food products. They also reduce spoilage during transportation, storage, and retrieval.
Dairy manufacturers use automatic L sealers for bulk packaging of milk, yogurt, and cheese products. The sealers can handle high volumes of packages at high speeds, making them suitable for the relatively high production capacity in dairy industries. The resulting packages help preserve product freshness, flavor, and nutritional quality and are also easy for consumers to use.
Cosmetic and pharmaceutical products are often sensitive to contamination and degradation. Automatic L sealers create sealed packages that provide these products with an extra layer of protection against spills, leaks, contamination, or expiration, especially during international shipping. Consumers can also see that all items are new when they purchase them. This is especially important for items like medicines that require a certain level of quality and effectiveness to be achieved and maintained.
Automotive and machinery component packaging:
Automatic L sealers are used to package automotive components like car interiors, doors, windshields, clutches, bearings, and drive shafts, among others, as well as mechanical parts in other machines. The individual parts are L sealed in clamshells or printed films, with vacuum sealing used to remove most of the air within the package. The packages save space and make it easier to organize components, which is perfect for assembly line workers. Besides, sealers create durable and secure packages for automotive and machinery components that lower the risk of damage or scratches.
Textile and garment packaging:
Textile and garment companies can use automatic L sealers to package their items, such as clothing, shoes, bags, bed linens, curtains, and upholstery materials. The sealers provide airtight and transparent packages that display the products attractively and keep them wrinkle-free, dust-free, and protected from damage during transportation and storage.
Apart from the above, educational, entertainment, and media companies use automatic L sealers to package their products, such as DVDs, CDs, video games, books, and software. The sealers create sealed packages that prevent unauthorized copying, ensure product quality, and protect the packaging from tampering or damage before purchase. Hardware and tools manufacturers can also use automatic L sealers to package their products, such as power tools, hand tools, measuring instruments, and tool sets. The L-sealed packages protect valuable tools from theft, dust, and damage on display racks or store shelves.
When purchasing an L sealer (both used L sealer and brand-new ones), it is important to ensure that the packaging machinery is of good quality and will be able to package products efficiently. Buyers should purchase L sealers that can perform the intended purpose efficiently and are easy to control. Buyers should also get sealers compatible with the type of product they are supposed to package.
The L sealer chosen should be able to provide an airtight and optimal seal to ensure all products are well packaged. Buyers should ensure that the automatic L sealer has the desired features, such as foldable end plates for easy operator access. The sealer machine should also be able to accommodate all the products that are supposed to be packaged. Get L sealers that can handle product volume and offer faster cycle times to enhance overall productivity.
Also, consider getting an L sealer that is easy to use and maintain. The manuals provided should be easy to understand and offer maintenance and operating guidance. If training is required for the employees to use the sealer, factor in the additional costs and time required to go for training.
Customers and employees' safety should be a priority when choosing an L sealer. Therefore, buyers should ensure that the chosen L sealer has the necessary safety features to minimize risks and avoid accidents. These include emergency stop buttons and safety guards.
L sealers come in different prices, and it is a good idea to set a budget before starting the purchase process. When setting a budget, consider additional costs such as maintenance costs and training to ensure the amount set is enough to cover the total costs.
If buying in bulk or for commercial purposes, it is a good idea to consult with product experts or suppliers to get recommendations on the best L sealers for one's business needs. Request samples to test the performance of the L sealers before placing a bulk order. When purchasing L sealers, get ones that are energy efficient and will help to cut down operational costs.
Q: What is the difference between an L sealer and an automatic L sealer?
A: An L sealer is a machine that seals products at the infeed direction to trim them into a rectangular shape; thus, the name ""L sealer."" The seal then moves to heat shrink tunnels that directly apply the heat for sealing and cutting the product. The primary difference between an L sealer and an automatic L sealer is that the latter integrates automatic bag trimming and sealing functions. This means that in a single step, the product will be enclosed in a bag, sealed, and trimmed to fit closely to the product, all without manual intervention. Automatic L sealers may also offer higher output rates, more sophisticated control systems, and greater safety features than their semi-automatic counterparts.
Q: Is an L sealer the same as a shrink wrapping machine?
A: No. An L sealer is designed to seal packages and is usually used together with a shrink wrapping machine that applies heat to the seal, causing it to shrink tightly around the packaged items. An L machine may sometimes be referred to as a shrink wrapping machine because it includes a shrink tunnel after it has sealed the package.
Q: What kind of films does an L sealer work with?
A: L sealers are generally compatible with various types of films, provided that they have the properties required for effective sealing and shrinking. Common types of films that L sealers work with include Polyethylene (PE) film, Polypropylene (PP) film, PVC film, and Centerfold films, to name a few. The films used with an L sealer should have the proper thickness and formulation to allow for a good seal and to shrink tightly around the product.
Q: Why do people use L-sealer shrink wraps?
A: L-sealer shrink wrap machines are popular for packaging many items because they offer a tamper-evident, secure way of packaging that protects the product. The package also offers a transparent package that shows off the product inside, and finally, the wraps provide a cost-effective means of packaging materials.
