In today's fast-paced consumer market, the packaging of liquid products must not only meet basic protection and transportation needs, but also take into account environmental protection, cost-effectiveness and user experience. As an innovative packaging solution, Soft Liquid Packaging Bag is using its unique advantages to set off a packaging revolution in many fields such as food, chemical industry, and medicine.
Traditional liquid packaging, such as tanks and iron barrels, has pain points such as high cost, expensive empty container return freight, and complex cleaning. Soft liquid packaging bags are made of multi-layer composite materials (such as 4PE+1PP, 3PE+1Alu+1PP, etc.) through ultrasonic welding, hot melting or bonding molding processes. They can perfectly fit 20-foot standard containers, with a single bag capacity of 14-24 cubic meters and a maximum storage and transportation of 24,000 liters of liquid. This design not only reduces transportation costs by 35% compared to barrels, but also completely avoids the cleaning, storage and overdue fees of traditional packaging through its one-time use characteristics.
Application scenarios: full coverage from food to industry
Food field: Products with extremely high hygiene requirements such as wine, edible oil, and concentrated juice can all be transported aseptically through food-grade soft packaging bags. Its inner layer material meets food hygiene standards, effectively avoids secondary contamination, and supports top filling and bottom drainage, which is easy and efficient to operate.
Chemical field: For corrosive liquids such as plasticizers, detergents, and lubricants, packaging bags made of special anti-corrosion materials can be selected, with anti-static grounding and temperature control design to ensure transportation safety. For example, for high-temperature liquids, an insulation layer design that can withstand 80°C can be used to meet special process requirements.
Medical field: For biological preparations that need to be stored at low temperatures, soft packaging bags can be deeply integrated with cold chain logistics, and the shelf life of products can be extended by optimizing the barrier properties of materials.
Compared with traditional packaging, soft liquid packaging bags have significant one-way freight advantages. Taking sea transportation as an example, its cost is only 1/3 of that of oil tank containers, and there is no need to pay for empty container return freight and cleaning costs. The packaging material is environmentally friendly and meets global environmental regulations. It is estimated that every 1,000 soft packaging bags can reduce steel consumption by about 50 tons and reduce carbon emissions by 40%.
Soft Liquid Packaging Bag is not only a form of packaging, but also a key tool for optimizing liquid logistics efficiency and costs. From chemical raw materials to food and beverages, from cross-border transportation to cold chain logistics, its application boundaries are constantly expanding. For enterprises, choosing soft liquid packaging bags means seizing the initiative in the fierce market competition; for consumers, it means a safer and more environmentally friendly product experience. In the future, this innovative packaging form will surely lead a new trend in the transportation of liquid products.
