Bulk bags have versatile purposes for storing and transporting goods across many industries. These durable and reusable bulk containers are an economical and effective way to handle, store, and move mass quantities of products. While they are reusable, bulk bags do have a shelf life and should not be used once there are signs of wear and tear or damage to the fabric and seams.
The shelf life of bulk bags is important to know. Despite their reputation for durability and strength, they do not last forever. The good news is that, under ideal circumstances, high-quality bulk bags made from virgin polypropylene can have a lifespan of three to five years.
Custom Bulk Bags is a leading manufacturer and supplier of flexible intermediate bulk containers (FIBCs) in South Africa. We produce up to 3.5 million bulk bags per year and our products can safely hold between 500kg and two tonnes of material per bag. We offer several UN-certified designs and attachments, making our products fully customisable to meet your unique needs.
Factors affecting the shelf life
The lifespane of a bulk bag is influenced by several factors. Firstly, the quality of the polypropylene used to make the fabric plays a critical role. Bulk bags made from virgin polymers have the longest shelf life as premium plastic has exceptional strength and resistance to tearing. Recycled polypropylene is certainly an option, although it will not be appropriate for every application and can break down more quickly.
Secondly, the manufacturing method used to make the bulk bags plays an important role. Strong seams and a sturdy overall structure are the result of a well-managed and reliable production process. In addition, strict quality control processes will guarantee a longer lifespan.
Next, the conditions of storage can impact the shelf life. The polypropylene fabric may deteriorate more quickly if it is exposed to harsh conditions like direct sunshine, extremely high or low temperatures, or excessive humidity. Optimising shelf life requires ideal storage conditions. Keep your bulk bags in a cool, dry and covered environment.
Lastly, a bulk bag’s life span will be impacted by how frequently it is used and how much weight it holds. Naturally, a bulk bag that is used frequently for large loads will wear out sooner than one that is used infrequently. Always perform a close inspection of your bulk bags before filling them. Any sign of damage or weakness means that the bags should be recycled and replaced.
Getting the most out of your bulk bags
You can extend the shelf life of your bulk bags by following these suggestions:
- Avoid direct sunlight – To reduce UV exposure, store your bulk bags in a shady area if indoor storage is not an option. You can also opt to have your bulk bags sprayed with a UV-resistant coating to extend their lifespan if they have to be stored outside.
- Keep them dry – Store your bulk bags in a low-humidity, dry location. Moisture can encourage the growth of mould and damage polypropylene fabric.
- Stack them correctly – To prevent moisture build-up and ensure adequate airflow between bulk bags, you need to stack them correctly. Place wooden or plastic pallets on the floor of warehouses and storage areas, and stack your bulk bags neatly in a pyramid configuration. Avoid packing stacks too tight or high since this can put undue strain on the bags.
- Examine them often – Inspect your bulk bags regularly for indications of deterioration, such as splits, punctures, or weakened seams. To prevent spills or mishaps, damaged bags should be replaced immediately.
Reusing bulk bags for extended lifespan
Although bulk bags have a limited lifespan, their value proposition is further enhanced by their reusability. Depending on the weight of the items they hold and how often they are used, premium bulk bags made from virgin polypropylene can be reused several times if they remain in good condition. This lowers long-term packaging expenses and improves sustainability.
