Significance of UV Masterbatches for FIBC Bulk Bags

When it comes to bulk packaging, the Flexible Intermediate Bulk Container (FIBC) bags play an important role. FIBC bags ensure the safety of goods during storage and transit. However, long-term exposure to UV rays can degrade the FIBC bags, thereby compromising the safety and integrity of packed goods. Perfect Colourants & Plastics Pvt.Ltd formulates  UV masterbatches that are specially tailored for FIBC bulk bags, protecting them from degradation caused by prolonged sun exposure. Our UV masterbatches are incorporated in the manufacturing process, preventing discolouration, yellowing and cracks & tears. PCPPL has an in-house weatherometer testing facility, and we check the retention level as per the customer's requirement, 200 hrs/250 hrs/500 hrs/1000 hrs. PCPPL provides precise loading percentage of UV MB to the customer as per the desired retention, even in adverse weather conditions. 

FIBC (Flexible Intermediate Bulk Container) is an integral part of flexible packaging materials. Without UV protection, the material used in FIBC bags can degrade due to prolonged exposure to sunlight.  This can lead to:

➤ Fading & yellowing

➤ Cracks & tears 

➤ Brittleness & loss of strength

➤ Bag failure leading to serious injuries

FIBC bags are manufactured with UV masterbatches to prevent photo-degradation and extend the life of these bulk bags. Bulk bag producers rely on UV masterbatch manufacturers in India for high-performance UV masterbatches that are specifically tailored for FIBC bags. 

UV degradation occurs due to long-term UV exposure. UV rays interact with chemical bonds holding material together, which creates free radicals, weakening the bond. UV masterbatches impart long-term strength retention, maintaining bulk bag integrity and preventing bag failure. 

UV exposure creates free radicals inside the polymer matrix. HALS-active type (Hindered Amine Light Stabilizers) serves as a stabilizer to neutralize these radicals and interrupts the degradation cycle & preserves polymer integrity. In this way, UV masterbatches allow for mechanical strength retention in FIBC bags by preventing photolytic degradation, which causes brittleness, tensile strength loss and tearing of fabric. Our high-quality UV masterbatches are tested for 200 hrs/250 hrs/500 hrs/1000 hrs to ensure strength retention under different sunlight conditions. 

It imparts excellent surface characteristics, long-term UV resistance and strength retention, contributing to the overall durability of FIBC bags. 

UV masterbatches maintain load-bearing capabilities, preventing catastrophic accidents or leaks during handling. 

When it comes to choosing the best UV masterbatch for FIBC bags, take into consideration the following factors: 

➤ The Type of Material Used: Different plastic materials require different types of UV masterbatches. 

➤ Environmental Factors: Take into consideration environmental conditions like humidity, temperature and sun exposure that can impact the MB. 

➤ Food-contact Applications: If the bag will be used for food storage, agricultural products or other food-related applications. 

➤ Colour & Aesthetics: Light or transparent colours may require a higher dosage of UV masterbatches, as compared to black pigments that provide a natural UV protection and durability. 

UV masterbatches ensure the FIBC bags are protected from UV radiation, contributing to a longer lifespan, enhanced safety and superior performance. Perfect Colourants & Plastics. Pvt is India’s largest masterbatch manufacturer offering a comprehensive range of MBs and additives. 

➤ Long-term UV resistance

➤ Reduced chalking and brittleness
