3. Filling method of liquid pouch

Liquid pouches can be filled using fully automatic, semi-automatic, or benchtop pump-filling machines. The pump helps move the liquid product through the channel into the waiting liquid pouch. The type of pump filler used depends on the nature of the product, the size of the liquid pouch, and other packaging tasks. These machines can also measure liquids during the filling of liquid pouches using a timer.

4. How to seal a liquid pouch?

There are two main types of equipment used to seal liquid pouches with heat:

1) Direct heat sealer:

The direct heat sealer connects directly to the liquid pouch layer by sending vibration energy to the bag. This type of sealer is relatively inexpensive because it does not require a lot of energy.

2) Pulse heat sealer:

An impulse heat sealer is suitable for the conventional sealing of liquid pouches. This type of sealer is cheaper because it consumes less power.

Some factors to consider before choosing heat-sealing equipment for liquid pouches include:

  • Material: What material the liquid pouch is made of must be considered.
  • Size: The thickness and width of the liquid pouch material will determine the sealing device to be used.
  • Speed: Consider how fast you want to seal the liquid pouch and choose the most effective sealing device.

12. How to test the quality of liquid pouches

Liquid products’ packaging plays an important role in determining their quality. Liquid pouches should ensure the safety of the product, therefore, specific tests may be carried out to determine the quality of the liquid pouches. Tests that can be used to determine the quality of liquid pouches include:

  • Bar code
  • lot number

Available liquid pouch printing options include:

1) Digital printing

Digital printing is widely used by liquid pouch manufacturers because it can provide a clean, shiny finish for liquid pouches. Digital printing is preferred due to its accuracy, versatility, relatively low cost, and availability of packaging materials. Digital printing is a bit expensive and it works by using inkjet printing on liquid pouches. It is a bit expensive compared to other printing methods. It offers neat and clear prints and is highly recommended. Because of its accuracy and performance, this printing option helps companies save a lot of money, labor, and time. The biggest advantage of digital printing is that it does not require printing plates. Some of the best features of digital printing options include:

  • Digital printing produces photographs and fine art printing.
  • Digital printing makes desktop publishing of high-quality printed products possible.
  • Digital printing enables variable data printing and advertising, allowing for a large number of printed products and personalization.
  • Optimal customization and accessibility are possible with digital printing.

2) Offset printing

In offset printing, the image of the device is transferred to a blank or plate cylinder by burning the image into a liquid pouch using a laser beam. After the ink is air-dried or UV dried, the liquid pouch is complete and ready to use. Offset printing is an efficient printing option because it can handle various types of materials. It also has a large capacity material that produces about 15,000 impressions per hour. In addition to being durable and versatile, offset printing is also very cost-effective.

3) Flexographic printing

The flexographic printing option uses flexographic letterpress. This printing option can accommodate a wide range of materials. Once the digital image is ready, the laser engraving plate prints the design using methods such as a central imprint roller, inline, or stacked. The liquid pouch is then finished, including cutting, folding and stapling. Flexographic printing uses very fast-drying ink, strong adaptability, and large ink coverage.
