Bulk bags are highly versatile and used in various industries for storing and transporting a wide range of products. From agriculture and mining to construction and chemicals, bulk bags are a reliable and cost-effective packaging solution.
However, it’s essential to understand the temperature limits of bulk bags and ensure that the products stored within those bags fall within the acceptable temperature range. Failure to do so may have catastrophic effects on your packaging products, which may put your employees and equipment at risk.
Custom Bulk Bags is a leading manufacturer and supplier of bulk bags in South Africa. We produce up to 3.5 million bulk bags per annum, all of which have a minimum safety factor rating of 5:1 and are manufactured in accordance with international standards and regulations. When it comes to storing or transporting products in extreme temperatures, it’s crucial to consider the limitations and potential impact on the bag’s fabric.
Understanding polypropylene and temperature extremes
Bulk bags are made from woven polypropylene tapes, a thermoplastic polymer. While this creates a highly durable and strong fabric, extreme temperatures can affect its properties. In high temperatures, the polymer molecules can soften, resulting in reduced strength and elasticity. Conversely, in extremely cold temperatures, the polypropylene can become brittle and more prone to tearing or breaking.
Sticking within the recommended temperature limits for bulk bags is essential to ensure the continued strength and durability of the plastic-based fabric. Exceeding these limits can lead to compromised integrity and potential bag failure. Therefore, it’s crucial to know the ideal temperature range for the products being stored or transported in bulk bags.
Ideal temperature range for products
While temperature limits may vary depending on the specific design and construction of bulk bags, a general guideline is to avoid exposing them to temperatures below -20°C or above 70°C. Products within this range can be safely stored or transported without significant impact on the bag’s fabric.
For products that exceed these temperature limits, additional measures can be taken to protect both the product and the bag. Inner liners and insulation materials can be used to create a barrier between the product and the bag’s fabric, reducing direct exposure to extreme temperatures.
For hot products, such as materials that require insulation, custom-insulated bulk bags can be used to maintain temperature conditions during transportation or storage.
