Top 10 Best Sealers for Plastic Bag
for May 2023

Sealers for plastic bags have become an indispensable tool in the modern world, aiding in the preservation and storage of various items. But where did it all start?

The history of sealers for plastic bags dates back to the early 19th century when one of the first forms of plastic, celluloid, was introduced. It was a revolutionary material that replaced ivory and tortoiseshell for making items such as combs, buttons and photographic film. However, it was not until the early 20th century that the first patent for a heat-sealing bagging machine was granted to Belgian inventor, Erlanger.

Fast forward to the 1960s, and polyethylene bags had become increasingly popular. In 1963, the first automated bag sealer was invented by Texwrap, a company that was founded just two years earlier. This machine cut, sealed and shrunk a bag in three separate stations, revolutionizing the way products were packaged.

The introduction of impulse sealers in the 1970s added a new layer of efficiency. These machines used less electricity and were more compact, making them ideal for smaller businesses. They also allowed for a better seal on thinner materials, such as those used for food packaging.

As the plastic bag industry continued to grow, sealers became more specialized. For example, vacuum sealers were introduced in the 1980s, which allowed for the removal of air from bags containing perishable items, greatly extending their shelf life. In the 1990s, continuous band sealers were introduced, which allowed for the sealing of bags in a continuous stream.

Today, sealers for plastic bags are ubiquitous, found in everything from small businesses to large manufacturing operations. They have come a long way since the early days of celluloid, and their impact on the modern world cannot be overstated.

It's fascinating to think that such a simple device, like a plastic bag sealer, has transformed the way we store and package goods. From Erlanger's heat-sealing bagging machine to the modern, high-tech sealers we have today, the history of these devices is a testament to human ingenuity and innovation.

The product described in the context above is a tabletop heat impulse sealer. The key design choices made by the manufacturer include the use of a manual sealing mechanism and the employment of energy conservation features, such as the use of a non-toxic, odorless, durable, reinforced, and compression material for the sealing strip.

Additionally, the product's extra durability is achieved through the use of a pure copper transformer, high-quality electric heating wire, and high-temperature resistant cloth. These design choices, combined with the manual sealing mechanism, ensure that the product is easier to use and has optimal sealing results.

The manual sealing mechanism helps users control the sealing process and achieve more consistent results, especially when sealing different types of poly bags. The energy conservation features make the product environmentally friendly and lower the operating costs, providing a compelling value proposition to the users.

Overall, the design choices made by the manufacturer of this tabletop heat impulse sealer have resulted in a user-friendly, durable, and cost-effective product that is capable of sealing a wide range of poly bags.

FAQ About sealers for plastic bag

1. What can I use to seal plastic bags?

There are several ways to seal plastic bags, including using a heat sealer, an impulse sealer, a vacuum sealer, or even a simple twist-tie or binder clip. The best sealing method will depend on the type of plastic bag and the intended use of the bag.

2. How do you seal a ripped plastic bag?

If a plastic bag is ripped, it can still be sealed using a heat sealer or an impulse sealer. Simply place the top of the bag between the sealing jaws and press down firmly to create a new seal above the rip. For larger tears or holes, it may be necessary to use a patch or tape to cover the damaged area before sealing the bag.

3. How do you seal thick plastic bags?

Thick plastic bags can be sealed using a heat sealer or an impulse sealer with an adjustable heat setting. The sealing time and temperature may need to be increased to accommodate the thicker material. It is also important to use a sealing tool with a wide sealing jaw to ensure a secure seal.

4. How do companies seal plastic bags?

Companies use a variety of methods to seal plastic bags, depending on the type and quantity of bags being sealed. Small bags may be sealed using a manual heat sealer or impulse sealer, while large quantities of bags may be sealed using an automated high-speed heat sealing machine. Some companies also use vacuum sealers or specialized sealing methods, such as ultrasonic welding or RF sealing, for certain types of plastic bags or products.
