Top Plastic Bag Sealing Machine Manufacturers in China

2. How Do You Choose Your Sealing Machine

Choosing a sealing machine involves considering several factors based on your specific needs and the nature of your product packaging:

2. 1 Application

Determine the type of packaging you will be sealing:

• Bag / Pouch

For example, snack, grain, powdered or liquid products such as flavored wafers, biscuits, rice, coffee, chocolate, drinks, soup, or sauce. Equipment for such an application comprises heat sealing or vacuum since it involves closing the bag.

• Blister Pack

Quite popular in the context of medicine production, electronics, and other small appliances and consumer goods. Sealing machines for this type of blister packets are developed to be so.

• Bottle / Jar

Used for liquids, powders, or granulated products. Induction sealing machines are often used for these applications.

• Box / Carton

This one is preferred on large or bulk items. It is usually preferable to apply carton sealing machines.

• Can

May be employed in food, drink, or industrial items. Sealers or double-seam sealers can be used here. Appropriateness depends on the application.

2. 2 Technology

Select the sealing technology that suits your packaging material and product:

• Impulse Sealing

Explores a quick energy boost to decrease the temperature of the sealing element. Ideal for thermoplastic materials and very frequently used in the sealing of bags and pouches.

• Induction Sealing

Induction sealing employs an electromagnetic induction to heat and seal the material. Sometimes applied to seal the lids of bottles, jams, and other jars having lids that are screwed on.

• Infrared Sealing

The sealing uses infrared radiation to heat and then seal the material in the process of carpet backing application. It is suitable for delicate materials.

• Laser Sealing

Uses laser beams to create a seal. This technology is accurate and works for many types of materials.

2. 3 Operation

Decide on the level of automation needed:

• Automatic

Most suitable for use in production lines that require many units to be produced in a comparatively short amount of time. These machines are almost fully automatic and can work through large volumes of clothes at once.

• Semi-Automatic

The one suitable for moderate production volumes. It is automatic but a little more flexible and allows you to have some control.

• Manual

Manual sealing machines are perfect for small-scale production or where volumes of production require a very special kind of control. They are cheaper and easy to use, though they are not ideal for large-scale production.

3. Production Process

The information about the specific production process of the manufacturer can inform about the quality and trustworthiness of the products. Evaluate the following aspects:

Well-selected Raw Materials

Ensure that the manufacturer employs high-quality raw materials. That may involve ensuring the origin of the materials used to compare them to the standard industry practice.

Search for quality standards as indicated by the availability of certain certifications like ISO.

Parts Processing & Inspection

Assess the manufacturer’s capabilities in processing parts with precision. This frequently results in the use of complex machinery and technology, all in a bid to perform a task.

Ask the potential suppliers about the procedures that are employed to determine if each part complies with the specifications that are regarded as standard. This can be done by using traditional methods on a computer like Computer Numerical Control machining and laser cutting just to mention but a few.

Intricate Hand Assembly

Assess whether the manufacturer has skilled workers who perform the assembly work in the production line. Hand assembly can be important, especially when it comes to creating correct and accurate fitments.

Go to them and inquire about their assembly line process on how they achieve order and quality.

Careful Machine Inspection

Ensure that the manufacturer has an efficient machine testing system that properly examines the machines to identify any problems before they are exported.

Examine the process of machine inspection, including functional tests, durability tests, and safety tests.

Strict Trial & No-load Run Test

Ensure the manufacturer gives the absolute best trial runs and no-load tests to verify its capacity in those scenarios.

You can ask for documents or reports on these tests to assess the outcomes and possibly the compliance with your needs.

Final Polishing

The last process of polishing is vital especially in the artistic look of the machine, and efficiency too. Ensure the manufacturer has this in mind.

Physically inspect the surface finish quality of the machines. It should be ascertained that the equipment is in perfect condition with no flaws and is fit for use as soon as it is received.

4. How Many Types Of Sealing Machines?

Ensure you know the full types of sealers before you choose a manufacturer to buy from. Different manufacturers specialize in various types of machines. So, identify which ones align with your needs.

Sealing machines are available in different types:

5. How Sealing Machine Works?

A sealing machine uses force and heat to join two materials to each other or to seal a material that is pumped through a tube. Here is a basic overview of how it typically operates:

• Heat source

The heating of most sealing machines can be done using elements like a heated bar or heated plate. The heat alters the state of the materials to be sealed. It could be plastic, foil, or any other flexible material.

• Pressure application

To accomplish this, the machine puts down pressure on the materials to create a closer and proper fit. It can be exerted in the form of a push/pull force, using compressed air in cylinders or even manual levers, depending on the type and size of the machine.

• Sealing process

When the materials are inserted in between the heating element or pressure mechanism, then the heat makes the surfaces that are intended to be sealed softer. Pressure is then applied to compact the materials by forcing them against each other with a firm pressure.

• Cooling and solidification

In some cases, especially for the sealed area, they take time and cool or solidify after a brief process called sealing. That helps to guarantee that the seal is not damaged and is in its correct state when placed on the product.

• Types of seals

Sealing machines can come with various characteristics that help to create different types of seals as flat seals, embossed seals, or cuts if the bags have to have some tear-open elements.

• Control and automation

Most of the present-day sealing machines are computerized. Automation ensures that the joints are sealed in such a manner that results in consistent and effective sealing on every project executed.

In general, sealing machines are multifunctional equipment, which is used in packaging industries, in the production line, and in some other sectors where the closure of some material is vital.

6. Which Sealing Machine Is Best?

Choosing the best sealing machine depends on your specific needs, such as the type of packaging material (e.g., plastic bags, pouches), the volume of packaging you need to handle, and any specific features or functionalities you require.

Assess the challenge and establish the precise specifications of your business. Selecting a sealing machine can be easier if you consider factors such as:

• Type of sealing

Depending on the packaging material, it is vital to establish the kind of sealing that would be useful, whether it is heat, vacuum, impulse, or the continuous band seal.

• Material compatibility

Ensure the machine of intended use will accommodate the types of materials, including plastic, polyethylene, and aluminum foil, and the thickness you will be sealing.

• Ease of use and maintenance

Select machines that are also easy to use and simple to assemble. The machine should also be easy to service. For instance, choose machinery with reduced blind spots. Some machines may need the services of a mechanic for routine check-ups, or sometimes, the parts have to be replaced.

• Brand and reviews

Check the credibility of the brands to know about their longevity, efficiency, and service quality that its customer support offers you.

7. How To Choose A Sealing Machine Supplier?
