What is an Automatic L-Bar Sealer?

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.

Different types of seal bars

There are two categories of seal bars: hot wire seal bars and hot knife wire seal bars.

Hot Wire Seal Bar

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.

Hot Knife Seal Bar

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.

Options to add to the L-Bar Sealer

Perforated Roller

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.

Selvage Rewinder

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.

Have you ever wondered how your favorite snack products are properly packed to keep them fresh and crispy? Are you a business owner trying to streamline your packaging process? What precisely is an automatic sealing machine, and how does it aid your manufacturing process?

Different from semi automatic sealing machine, fully automatic sealing machine is a piece of machinery that automates the process of sealing bags, pouches, cans and other packaging materials. It is intended to provide a quick, effective, and consistent way of sealing products, keeping them fresh and protected during transportation and storage. In this blog post, we&#;ll go deeper into the realm of automatic sealing machines, looking at its functionality, benefits, and uses.

How Do Automatic Sealing Machines Work?

The primary function of an automatic filling and sealing machine is to form airtight seals on a variety of packaging materials. The method typically includes the following steps:

Feeding: Packaging material is fed into the machine, either manually or automatically.

Sealing: The machine employs heat, pressure, or a combination of the two to seal the edges of the packaging material, resulting in an airtight closing.

Cutting (optional): Some machines may have a cutting feature that removes superfluous packaging material, resulting in a clean and professional finish.

Automatic sealing machines use a variety of sealing processes, including heat, ultrasonic, and induction. The choice of sealing method is determined by the packaging material and the product&#;s specific requirements.

Types of Automatic Sealing Machines

There are various types of automatic sealing machines, each of which is built for a certain packaging material and sealing procedure. Some typical categories are:

Tray Sealing Machines: An inline automatic tray sealing machine designed for medium to large-scale production. It features a vacuum and gas function for modified atmosphere packaging (MAP), enhancing the shelf life of food products. It operates at approximately 5 cycles per minute and can accommodate various tray sizes

Continuous Band Sealers: These machines employ a conveyor to transfer packing material past a heated sealing device, resulting in a continuous seal along the length of the package.

Impulse Sealers: These sealers use a quick, regulated pulse of electrical energy to generate heat for sealing. This kind is ideal for sealing heat-sensitive materials since it reduces the chance of harm.

Rotary Sealers: These machines employ a rotating wheel to impart heat and pressure to the packaging material, resulting in a strong and lasting seal. Rotary sealers are ideal for high-speed production lines.

Canning Sealing Machines: Designed for sealing canned products, these machines ensure that food remains uncontaminated and extends shelf life

Vacuum sealers remove air from packages before sealing them, resulting in an airtight seal that maintains product freshness and extends shelf life.
