Носик is an innovative and practical packaging solution that is being widely used in food, напиток, daily chemical, pharmaceutical, and other industries.

It is not only convenient to carry and store, but it can also effectively reduce packaging waste, which is in line with the current trend of environmental protection. ​

The selection of appropriate Spout Pouch Materials plays a decisive role in the performance, function, cost, and environmental protection of Spout Pouch. Wrong material selection may cause product leakage and deterioration, affect brand image, and increase costs; on the contrary, the correct material selection can improve product quality and market competitiveness, and bring more commercial value to the enterprise.

1 、Product characteristics and requirements for spout pouch materials

Capacity

Currently, the spout pouch can accept a customized demand from 30ml to 10 liters

When supporting large-volume products, the key material required is NY (Nylon) – it is characterized by its elasticity and ability to effectively prevent the package from being punctured, ensuring the integrity of the product and the sealing of the package.

Special temperature and usage requirements

Many liquid products, such as milk or sauce, have requirements for filling temperature,long-term storage and need to be pasteurized 100degree or sterilized at high temperature 121degree-135degree . They usually require materials that can withstand high temperature filling, High barrier properties and cooking.

Aluminum Foil and Vmpet foil are both barrier materials that meet the above requirements.

Storage method and cost

The storage method also has high requirements for the spout pouch material such as If the product needs to be frozen to -18°C or stored at room temperature for more than 1 year, the material must be able to protect the contents well and prevent deterioration and leakage.

In addition, compared with traditional bottles and glass jars, spout pouches are relatively cheap, have low transportation costs, and are highly safe.

Filling method

The high usage of daily necessities also requires a large daily production volume. This also requires a high production speed, and machine filling is an indispensable production method for spout pouches.

The precise nozzle size perfectly docks with the machine, which reduces leakage during filling, improves efficiency, reduces labor costs, and protects the cleanliness and hygiene of the product packaging.

2、Commonly used spout pouch material combinations and their functions

PET+NY+PE

PET can meet the design requirements of spout pouches, whether they are glossy, matte, or UV-effect. Basically, it is the first layer of the spout pouch.

Nylon has strong toughness, whether it is a liquid or a product with particles. It can protect the safety of the bag itself during transportation and storage.

This combination is the most common and most frequently used structure

PET+NY+WHITE PE

The difference with PET+NY+PE material structure is that the last layer of this structure, that is, the WHITE PE .

This structure is most commonly used in chemical products, such as laundry detergent, cleaning agents and other products with acidity and alkalinity, but do not require strong barrier properties. Поэтому, white PE is a relatively low-cost option compared to pure aluminum and aluminum plating.

PET+NY+ALUMINUM FOIL+PE

Aluminum foil is a relatively expensive intermediate layer structure, widely used in products with a long shelf life that need to block oxygen, moisture, and ultraviolet rays.

This material structure is widely used in high-quality cleaning products, sauces, and daily condiments

PET+NY+VMPET+PE

VMPET (metallic) has a lower cost than Aluminum foil, but it also has the same barrier effect. It is also suitable for products that require barrier properties but have lower cost and sales value.

In addition, the metallic luster of VMPET foil can enhance the appearance of the packaging, making the product more eye-catching on the shelf and attracting consumers’ attention.

PET+NY+ALUMINUM FOIL+RCPP

This material structure is currently the most widely used for products that require high temperature sterilization and retort product.

Replace the last layer structure with RCPP. It can withstand high temperatures up to 135 degrees and has a strong barrier effect.

Currently, milk products, children’s complementary foods, etc., have high food safety requirements and need to prevent food from spoiling easily, and this material structure will be chosen

Selecting the material of Spout Pouch is a complex and critical process, which requires comprehensive consideration of product characteristics, packaging functional requirements, cost budget, and sustainable development. Different materials have their own unique properties and characteristics. No material is suitable for all situations.Enterprises need to make the best choice based on the specific needs of their products.

 In this process, it is a wise choice to cooperate with a professional packaging company. Professional packaging companies have rich experience and professional knowledge. They can provide personalized packaging solutions according to the needs of enterprises, help enterprises choose the most suitable materials, optimize packaging design, improve packaging quality, and reduce costs.
