The design of on-board liquid bags must meet four key points: safety, storage, usability, and sealing. Safety primarily refers to the strength of the container bag. During design, factors such as packaging volume, weight of the contents, and number of packaging units should be considered, as well as the distance of transportation, the number of handling times, and the type and method of transportation used. Storage should be based on the user's usage conditions, with reasonable material selection and proportioning. The anti-aging ability of plastic products under sunlight exposure is a current concern and a common issue encountered in the practical use of container bags. When designing container bags, it is necessary to fully consider the specific ways and methods in which customers use the bags, such as lifting, transportation methods, and the properties of the loaded materials. Additionally, it is important to consider whether the packaging is for food, and whether it is non-toxic and harmless to the food being packaged. The sealing requirements vary depending on the packaging material. For example, powdered materials or toxic substances, or items that are sensitive to contamination, have very strict sealing performance requirements. Materials that are prone to moisture or mold also have special requirements for airtightness.  

The on-board liquid bag is primarily an alternative form of the container liquid bag, combining with the liquid bag form used by trucks to save packaging and transportation costs.

On-board liquid bag:

Flexitanks used in conjunction with flatbed trailers and heavy-duty trucks can be customized according to customer requirements and truck dimensions. On-board flexitanks solve the problem of having to use containers for domestic urban transportation of flexitanks, reducing customers' transportation and packaging costs

Flexitank is a new type of liquid bulk cargo packaging container used in combination with containers. LPT flexitank is made of food-grade low-density polyethylene (LDPE) and polypropylene (PP) through heat sealing and sewing processes, and has the advantages of safety and hygiene, high operational efficiency, and cost savings for customers in packaging.

Advantages of container flexitanks:

1. Low packaging procurement cost. Compared to traditional liquid packaging containers, LPT flexitank can save customers 50-80% of packaging procurement costs.

2. Reduce customers' logistics costs. Containers equipped with flexitanks can accommodate 25 cubic meters of cargo, representing a 56% increase in container utilization compared to traditional packaging containers.

3. Safety and hygiene. The inner material of the liquid bag is food-grade low-density polyethylene, which can directly come into contact with food-grade liquid products; the LPT liquid bag is a disposable package, requiring no cleaning, making it more compliant with food packaging requirements.

4. High operational efficiency. It only takes 20 minutes to load and unload a container flexitank, which is convenient and labor-saving.

5. Strong applicability. Container flexitanks can meet the transportation requirements of railway, sea freight, and highway.

6. Green and environmentally friendly. The material of the container flexitank is biodegradable, recyclable, environmentally friendly, and non-polluting.
