The type of liquid packaging solution you&#;ll end up with will depend on a variety of factors, including whether you want an automated or semi-automated solution.

If you&#;ve set out to find a liquid packaging system, this guide will walk you through all of the important information you need to keep in mind when making your decision. 

What is Liquid Packaging?

Liquid packaging refers to the process of packaging up any sort of liquid product, from beverages to cleaning agents. Liquids may be packed in a variety of container types with various seals and caps. 

If you&#;re looking for a liquid packaging solution, you may be seeking a machine to rinse the bottles, fill the containers, or cap and seal them after they have been filled. In general, a liquid packaging system refers to the filling machinery itself, but a complete solution will do all of the above.

How do you pack liquid products?

Packing liquid products requires extra care because liquids may spill, bubble, or overflow when not handled properly. This requires a smooth conveyor belt, at the very least, but also a liquid filling machine that is able to maintain pressure and temperature to keep the product at the right viscosity. Here&#;s a closer look at all of the factors that need to be controlled. 

Managing Fill Temperature

Managing the temperature of a liquid as it is being packaged is important for a few reasons: When dealing with certain beverages, keeping a liquid in a given temperature range is necessary for preserving the taste and freshness of the product. However, temperature also impacts the viscosity of many liquids.

For instance, while some liquids remain easily pourable at a high temperature, they may become thicker and more difficult to work with when cooled&#;and vice versa. 

Advanced liquid packaging systems will allow you to control the precise temperature of the product as it is moving through the system and into the containers. This is necessary for controlling both viscosity and quality in many situations. 

Controlling Pressure

Pressure must be controlled for a number of liquid products, especially carbonated beverages where pressure differences could cause the product to bubble or foam and overfill the container. 

Investing in a liquid packaging system with pressure control is necessary when working with these liquids in order to prevent spills and ensure staff safety and better product yield. 

Why Size Matters

When determining the amount of product you would like to package into a given container, you must make the container slightly larger. Failure to leave this room will lead to issues when it comes time to fill and ship your products because natural changes in temperature will cause the liquid to expand. 

If you do not account for enough excess volume in the container, product could burst and overflow after being filled, especially during transport or after sitting on store shelves for some time. Factoring this into your liquid packaging solution is a must-do. 

Benefits of Using Liquid Packaging Systems

By far, the primary benefit of using a liquid packaging system is that it allows you to produce that much more product. In addition to time-savings, other benefits of using a system include:

• More accurate and consistent filling
• Reduced product loss
• Less manual labor required for production

Should we use automated or semi-automated liquid packaging system?

Liquid packaging systems are able to speed up the production line, especially when they incorporate a conveyor belt to automatically pull the bottles under the filling machine. 

From there, the capping process can also be automated, and so can the sealing process. Labeling machines and other equipment can also be incorporated into the production line to create a fully-automated liquid packaging system. 

Of course, semi-automated packaging systems are suitable for many operations. With these solutions, a person is often required to place the bottle under the filling machine, place on a cap, and use a manual interface to seal the container. The best choice for your operations will depend on a few criteria. 

What to Know Before Packaging

Before packaging any liquid product, you need to think about a few key elements:

Liquid pouch packaging is becoming increasingly popular across a variety of industries. It&#;s a flexible, lightweight, and often eco-friendly packaging solution for liquid products. This packing type also offers significant benefits over traditional rigid containers like bottles and jars.  So lots of manufacturers choose it for packing their liquid products. If you are also interested, a thorough understanding is a must.

What is Liquid Pouch Packing?

This is a packaging type used to contain and protect liquid products in flexible, convenient bags. It creates a strong barrier to keep liquids safe from external elements like air, moisture, and contaminants. And they are usually made from durable materials to prevent leaks. Furthermore, liquid pouch packaging often comes with user-friendly features like resealable caps, spouts, or tear notches. So it is easy for consumers to use and store the product without causing waste. These features also help in extending the product&#;s shelf life after opening.

Pouches can also be customized in various shapes, sizes, and colors. You can choose the most suitable one to match branding and product needs. This makes your products more attractive and helps them stand out on store shelves.

Applications of Pouch Packaging:

This packing type is used in various industries.  Here are some of the main uses.

• Pharmaceutical and healthcare industry. They are always used for storing liquid medicines, syrups, health supplements, hand sanitizers, etc.
• Food and beverage industry. Common examples include juices, sauces, yogurt, cream, soups, etc.
• Personal Care and cosmetics. pouches are used to package liquid shampoos, conditioners, lotions, and liquid soaps. These pouches can be resealed, making them ideal for both single-use and refillable purposes.
• Industrial Liquids. They are are used for storing lubricants, cleaning solutions, and other liquid chemicals. Their durable, leak-proof construction makes them suitable for handling harsh liquids.

Five Types of Liquid Pouch Packaging

Liquid pouch packaging comes in various forms, each designed for specific uses and industries. These types differ in their structure, functionality, and features. Here are some popular types for your reference.

Stand-up Pouches

This is the most common type of liquid packaging. It has a bottom gusset. So it can stand upright on shelves for display. This design makes the package stable and attractive for retail products. Stand-up pouches often have resealable closures like zippers or spouts. This lets consumers use the product multiple times without leaking or contamination. Therefore, stand-up pouches are perfect for items like juices and sauces.

Spouted Pouches

This type is equipped with a nozzle or spout at the top and a wide, flat base.  The spout can be screwed or snapped shut to stop liquid from leaking, making it good for reuse. The spout can also be resealed like stand-up pouches. It is convenient for on-the-go consumption. These are commonly used for beverages, sauces, liquid detergents, and baby food.

Pillow Pouches

As the name suggests, pillow pouches resemble a pillow when filled. These pouches are typically sealed on three sides: two vertical edges and one horizontal edge. The fourth side is used for filling and then gets filled. Unlike the former two pouches, pillow pouches do not have a bottom gusset. So they do not stand upright on shelves.  They are typically designed for single-use, so once the package is opened, it is not resealable. If you want to produce sauces or condiments, pillow pouches are a good choice.

Flat Pouches

Flat pouches are also known as 2-side seal or 3-side seal pouches. They leave one side open for filling the liquid product. They can lie flat once they are filled. This makes flat pouches compact and easy to stack and transport. Same as pillow pouches, this type can&#;t be resealed, either.

Flat pouches are usually small and thin. It makes them ideal for packaging small liquid volumes, such as sauces, shampoo samples, liquid medicine, etc. In addition, there are many shapes of flat pouches to choose from. The most common shapes are rectangular and square. You can also customize the shapes to meet your production needs. For example, flat pouches in personal care may mimic the shape of a product bottle for more attraction.

Retort Pouches

Retort pouches are specially designed for products that undergo heat processing. They are typically for sterilizing and extending shelf life, without the need for refrigeration. They can withstand the high temperatures used in sterilization (usually over 120°C). It makes them suitable for cooking or preserving food directly in the packaging. So they are commonly used for ready-to-eat meals like soups, stews, sauces,etc.

Retort pouches are made with layers of flexible materials. Typically, they have an outer layer of polyester for durability and printability. A middle layer of aluminum foil act as a barrier against light, moisture, and air. And an inner layer of polypropylene is included, which is heat-sealable and food-safe. They are usually sealed with heat healing to ensure a leak-proof and airtight package.

Six Common Materials to Make Liquid Pouch Packing

The materials for liquid pouch packaging need to have several key features. They include leak proof, durability, heat-resistance, moisture-resistance, and safe for food. Common liquid pouch packaging is usually made of multiple layers of materials. Each of them has a different function to ensure the safety and shelf life of the liquid product. 

PE

PE is a widely used plastic material in liquid packing. It can directly contact with liquids, so It is often applied for the inner layer of pouches. PET is ideal for packaging drinks, food, or chemicals. It also has good sealing and flexibility, making it easy for filling operations.

PP

PP is usually used for the outer layer of pouches. Because it has strong chemical resistance and mechanical strength, along with good transparency. PP can withstand high temperatures, so it is suitable for packing goods that require microwave heating or high-temperature sterilization. This material is also good at resisting corrosion from chemicals like acids and alkalis. Therefore, many manufacturers use it to hold chemical liquids or oily products.

PET

PET features good strength, stiffness, and high barrier properties. So it is often used as the outer packaging layer. This strengthens the pouch and makes it less likely to break or wear out. PET also has good moisture and gas barrier properties, preventing oxygen and moisture from entering. It helps extend the product's shelf life. With good stretch resistance, PET is ideal for printing. It keeps patterns clear and does not fade easily. PET is often used for packaging acidic liquids, dairy products, or food that requires high protection, like juice and sauces.

Aluminum Foil

Aluminum foil is commonly used as the middle layer in pouch packaging. Because it has excellent barrier properties. This material can almost completely block oxygen, light, and moisture. So it is ideal for packing liquids sensitive to light or that require long-term storage. Aluminum foil features high heat resistance, suitable for products that need sterilization at high temperatures, such as ready-to-eat meals.

Polyamide

Although more commonly used in solid packaging, PA is also applied in some liquid pouches. It features high puncture resistance and durability, suitable for products that needs good strength and protection. It helps prevent the packaging from breaking during heat treatment or transportation. This helps extend the product's shelf life. If your products like soups require high temperature and pressure for sale, PA is a good material for packing. However, compared to other materials, PA costs much higher.

EVOH

EVOH has a high barrier against gases, making it a great material for products sensitive to oxygen, like functional drinks. It is usually not used alone but combined with other materials like PE or PP. It is more often found in high-end food and functional drink packaging, especially for products that need to stay fresh for a long time.

The End

Pouch packing for liquid offers a versatile, efficient, and eco-friendly packaging solution. It not only enhances product preservation but also minimizes waste and reduces transportation costs. If you want to make liquid pouch packaging, a high-quality liquid filling machine is a must. If you don&#;t know how to choose a suitable one, contact iPharMachine for help.
