The heat sealer machine is a professional device produced by our factory which is used to seal the plastic bags into the rounded edges by heat. The heat sealer machine is widely used in a variety of industries, such as food, pharmaceuticals, manufacturing, etc.. It can be used to keep the products from contamination and prolong the shelf life. It is especially useful for those products that are easy to get wet or be spoiled.

There are numerous types of bag sealer machines that can be identified according to their working method, material and purpose. Impulse sealers, direct heat sealers and continuous band sealers are the most popular application forms.An impulse sealer, that is a type of hand sealer, is highly energy-saving and more suitable for sealing a thermoplastic substrate. It applies heat just when you press down the sealing arm. While a direct heat sealer keeps a constant temperature and suitable for sealing thicker material like foil.The continuous band sealer is a fully automated machine and well-suited for use on a high-volume production line.

The main task of a bag sealer machine is sealing the bag’s opening in a way that it’s airtight and prevents any air, moisture and contaminants from getting in. This is especially useful in the food industry because it helps to preserve food. Furthermore, in the medical and pharmaceutical sectors, bag sealers help to keep sterile products sanitary.

How a bag sealer works depends on the type of machine, but the general principle is that the sides of the plastic bag are heated up so they melt together and form an airtight seal. Impulse sealers have a sealing bar that heats up quickly when you press down the handles, so it heats and then melts the plastic and seals the bag together. Most of these sealers have adjustable timers for the amount of time that the bar stays down while heating, which you can use to control the amount of time the bag heats, which will help you with getting a strong seal without getting holes in your bags.

A direct heat sealer works by keeping the sealing bars at a constant temperature. It has a thermostat that controls the temperature to keep it consistent. This makes it particularly useful for thicker materials but also things like cellophane and foil where the temperature must be raised higher to make a good, robust seal. A direct heat sealer is often used in industrial sealing applications.

This device automates the process of sealing. It also includes a belt that moves the bags forward into the heated jaws for sealing. These sealing devices include a continuous band method to seal packaging at very high speed, which makes them ideal for a production line or when speed in packaging products is crucial. The different types of packaging that can be used by the band make these sealers suitable for various packages. In addition, these machines can also print the expiration dates and batch numbers on the package during the sealing process when the product is inside the bag.

There are a number of different steps to using a bag sealer machine. If using an impulse sealer, you must adjust the timer depending on how thick the bag is. You then place the bag on the clamp rollers or the seal bar and press the sealing arm down. The machine will apply heat for the designated amount of time. During this time, the plastic will melt and form a seal. You will need to hold the arm down until the sealing cycle is finished to avoid weak seals.

In a direct heat sealer, the user should first set the temperature with the thermostat and place the bag between the sealing bars. Then press the button to apply the constant heat. The bag must be watched carefully because the heat can scorch the material. Direct heat sealers also tend to have a foot pedal or automatic operation for industrial applications.

Continuous band sealers are more complicated. They need setting up for the first time including the speed of the conveyor and the temperature of the sealing element. Bags must be placed on the conveyor belt which passes them through the sealing jaws. The operator must ensure that the bags are positioned correctly, as well as the temperature of the seal is sufficient for the material of the bag. Continuous band sealers sometimes have additional features such as printers with information that is applied to the sealed bags.

Pricing for bag sealer machine is always changing. The price depends on the type, features and capacity of the machine. Impulse sealers are the cheapest. Its price ranged from $20 to $200. These machines are very simple in working and inexpensive, so business owners and people in home use this machine. The reasonable machine with little extra features like adjustable sealing widths and built in cutters are bit more pricey.

Direct heat sealers work by heating up the substrate between two pieces of your packaging product so as to fuse them together. These machines are a bit more affordable than lamination sealers and typically cost the consumer between $100 and $500. The cost of direct heat sealers largely depends on the machine’s sealing capacity, temperature range and build quality. Industrial-grade direct heat sealers are on the more expensive end. These machines are fitted for heavy-duty use and are a great investment for businesses that need a more powerful and reliable sealing option.

The continuous band sealers are the most expensive of all, priced as little as $500 but as much as $5,000 or more for a high-end machine. These units are more advanced and feature faster sealing speeds, an integrated printing system, and a durable and high-quality construction. These next-level sealers are worth investing in for those that operate in production environments and need to save yardage as well as reduce their labour costs over time.

The type of bag sealing machine you need will depend on your requirements and budget. Here is our take on the main bag sealer types and some top recommended models in their class:
