Spout couch refers to a type of flexible packaging bag featuring a tube or lip projecting from the container.
It is specifically designed for liquid or semi-liquid products and is becoming an economical and eco-friendly alternative to plastic bottles, tins, and tubs.
They come in different sizes, shapes, and styles, making it easy for you to get one that meets your preference.
Methods Of Sealing Spout Pouch
Technically, a spout pouch is sealed using specialized sealing machines.
Heat sealing is the last step in packaging a product in this bag.
Normally, two main types of plastics are used for producing spout pouches, and they include thermosetting plastic and thermoplastic.
You can close a barrier pouch made of thermoplastic material repeatedly.
On the other hand, a spout pouch made of thermosetting plastic is permanent.
Here is the main industrial technique of sealing a spout pouch;

Heat sealing is an ideal way you can use to seal a spout pouch both for domestic and industrial applications.
Essentially, it provides tidy and organized results offering ultimate satisfaction to you and the customers.
Moreover, this method enhances safety of the products inside the spout pouch by preventing them from exposure to contamination elements.
Sealing spout pouch using heat method also reassures the customers that the product has never been opened or tampered with.
However, for a successful heat-sealing process of spout pouch, the bag must have a heat-sealable laminated interior.
Besides, you need to have different materials and items to effectively heat-seal a spout pouch, such as the following;

Considering Spout Pouch To Seal
Ensure you have an excellent and solid spout pouch.
The design construction of a sprout pouch is imperative in determining the effectiveness of the sealing result.
Moreover, it needs to be unique since this allows you to maximize the profit.
Besides, ensure you have the right size, shape, and design of spout pouches for the specific products you are packaging.
It is vital since it allows you to stand out among your competition and make it easy for the customers to identify the product.
Choosing Heat Sealer For Your Pouch
It is imperative to choose a suitable heat sealer for sealing spout pouch based on the bag material.
Also, determine the thickness and width of the product since it makes it easy to buy a sealer that can guarantee effectiveness when sealing the spout pouch.
Ordinarily, you can always choose between an impulse sealer and a direct sealer.
Impulse sealer hardly warms up; instead, it seals by applying energy pulse to the particular sealing section and follows instantly by cooling.
It uses electrical power when the jaw is lowered, thus ideal for sealing spout pouch made of thermoplastic materials.
Primarily, this sealer works by warming up a part of the spout pouch then swiftly subjecting it to powerful heat followed by instant cooling.
Direct sealer, also known as hand pressure heat sealer, uses power as long as it stays on.
In essence, this spout sealing method keeps a constant temperature at the jaws, which enable a uniform heat dispersal to form a solid seal.
It has better heat penetration thus suitable for sealing spout pouches with relatively thick materials.
Roomy Working Area For Sealing Spout Pouch
Ample working space is ideal since it offers suitable space, comfort, and safety.
Choose a relatively flat surface with adequate light and ideal temperature.
Once you have all these elements, you can go ahead and start sealing the spout pouch using the following procedure;
- Lower the machine setting and adjust accordingly.
- Fill the pouch with the desired content but don’t let the product fill into the zipper area of the bag.
- Run your fingers softly across the zipper to close the pouch safely.
- Put the top of the filled spout pouch between the bar seal.
- Press moderately for about 2-3 seconds, then release, and you’ll have a sealed spout pouch.
If the spout pouch fails to seal accurately, adjust the temperature upwards until you attain a complete seal.
Additionally, you can use a double impulse heat sealer where both clamp sides are heated.
In essence, this seals a spout pouch of 10 mils easily and faster.
The Ideal Spout Pouch Sealer To Consider
Printed spout pouches
Technically, spout bags and other barrier bags are often made from numerous layers.
To make a single uniform structure, these several layers are laminated.
Heat sealers are suitable for sealing these layers and make them a single structure.
Ideally, a spout pouch sealer can seal different types of spout pouches you see around in various outlets.
An impulse sealer is usually used for sealing different spout pouches.
However, you can use other types of spout pouch sealers depending on the volume of the task.
Essentially, if you are sealing several spout pouches, using a machine is the most practical approach.
A hand sealer is not practical for sealing thousands of spout pouches.
Instead, it will take longer to accomplish, and the process will be relatively inefficient.
Cost Of Spout Pouch Sealer
There is no definite price for purchasing a spout pouch sealer.
Ordinarily, it depends on several factors, including the size and design of the equipment.
It is also dependent on the brand of the specific sealer you are buying.
However, you can find a basic spout pouch sealer at the cost of $100, primarily for domestic use.
You can also find a relatively advanced one for about $400-$500.
But for an industrial spout sealer, you can spend at least $1000 to get an ideal one with advanced features.
With such a budget, you can get a suitable spout pouch you can use for filling and sealing sophisticated bags.
