How to Store and Transport Liquid Products in Spout Pouches Safely

Spout pouches are rapidly changing the way liquid products are packaged, stored, and transported, with superior flexibility and leak-proof properties compared to rigid containers. For a spout pouch to truly deliver value, especially in terms of safe storage and transportation, its design, materials, and processing must meet high-performance standards. As a spout pouch manufacturer that can support customer customization, let me take you to learn about spout pouches.

Why Do Spout Pouches have Advantages in Transportation？

The impact resistance of the spout pouch is a highlight of their transportation. Because spout pouches are made of soft film materials, they can better absorb external impacts than hard containers such as glass bottles or plastic bottles.

The structural design of the spout pouch also enhances its stability during transportation. Spout pouches usually adopt a reinforced double heat-sealed edge design, which enables them to withstand a certain amount of pressure and weight during transportation without being prone to cracking or leaking. Spout pouches can be stored and transported in a variety of ways, such as roll packaging, stacking, and box packaging, which not only increase the loading density of goods but also effectively save storage and transportation space. Compared with traditional containers, spout pouches have the characteristics of sealing, impact resistance, stability, and flexible packaging forms.

How to Ensure the Safe Transportation of Liquid Products in Spout Bags

Choosing the Right Liquid-resistant Material

From a manufacturing perspective, material selection is critical when designing a spout pouch for liquid applications.

For food-grade liquids such as juice, puree, or milk, PET/NY/PE multilayer composite films, which have a strong seal layer and good barrier properties, are highly recommended. For more sensitive or oily substances such as detergents or industrial chemicals, PET/AL/NY/PE structures with aluminum foil layers have excellent oxygen, moisture, and oil barrier properties. For customers who need high-barrier, recyclable solutions, co-extruded films with EVOH barrier layers are also a wise choice.

If you need custom spout pouches, all our materials meet FDA or EU food safety standards and are ensured to pass rigorous puncture and seal strength tests before mass production.

Structural Design to Prevent Leakage and Bursting

Leak-proof transportation depends not only on high-quality materials but also on reasonable structural design. Reinforced gussets help the packaging bag stay upright during transportation and retail display, while double heat-sealed side seams enhance anti-burst performance. Tamper-proof bottle caps ensure the integrity of the product during long-distance logistics, and choosing the right nozzle and bottle cap size according to the viscosity of the liquid can significantly reduce the risk of leakage.

GQ PACK custom spout pouch factory also provides custom mold nozzle solutions to meet unique dispensing needs, whether it is a high-flow sports drink or a thick cosmetic gel.

Key Storage Considerations

Temperature control is the most important storage factor. Extreme heat can weaken the seal, while cold temperatures can cause the film to become brittle. We recommend keeping the storage area between 10-25°C (50-77°F) and relative humidity below 65%. Proper stacking techniques are also important; use corrugated dividers between layers and limit stack height to 3-5 bags to prevent crushing. For long-term storage, light-blocking materials can protect UV-sensitive items such as vitamins or essential oils from degradation.

Optimize Transport Safety

Bags are at greatest risk of damage during transport. We recommend using strong secondary packaging, such as corrugated boxes with internal dividers. For pallet transport, stretch wrapping provides the necessary stability while ensuring ventilation. Avoid stacking other heavy objects directly on top of the bags, and always use cushioning material around the nozzles.

For international shipments, GQ PACK ensures that all bags and their packaging comply with the regulations of the destination country, especially important when transporting flammable or corrosive liquids.
