Impact of Additives on Plastic Bucket Durability and Lifespan

Plastic buckets are used in diverse applications covering a wide market. To some extent they are nearly as ubiquitous as the common plastic bags in some parts of the world. Their use can be as simple as serving as a decorative item to collecting harvest from farmland to  hurling several kilos of material into the hopper of an industrial machine. Some of these applications require the buckets to be exposed to rather harsh conditions such as UV exposure, heat, reactive chemicals, solvents, oxidation and humidity. Without the protection of additives, the plastic in its neat form might begin to fail or experience degradation under these conditions. In other cases the plastics are used in heavy duty work where it needs to withstand high impact and hold heavy loads and withstand non uniform pressure during lifting.‎‎Very commonly, plastic buckets used for packaging of products such as paints are even re-used beyond their packaging function. This keeps the used plastic out of the waste stream for longer. Therefore making plastic buckets more durable with a longer lifespan improves their sustainability.‎This article explores how additives are used to make plastic buckets more durable and last longer.‎‎

Factors that determine durability and Lifespan of Plastic Buckets

‎In order to understand how additives impact the durability and lifespan of plastic buckets, we first explore the factors that determine their durability and lifespan.‎‎

Application‎

The application will determine the nature and magnitude of stress the plastic bucket will be exposed to. Ensuring that the intended application is considered during the product design makes for more durable buckets.‎‎For instance, if a bucket is going to be constantly exposed to a hot sunny environment, this should be considered and the type of plastic compound to use in the manufacturing should be one that offers resistance to such conditions‎‎‎Plastic buckets can be applied in general purpose for storage and packaging of:‎‎‎‎

• Food items ‎‎
• Chemicals‎‎
• Paints ‎‎
• Fertilizers‎‎
• Pharmaceuticals
  ‎
• Pet food‎‎
• Seeds and grains‎‎‎‎

They are also used industrially for:‎‎

• Conveying feedstock into hoppers‎‎
• Bulk materials handling ‎‎
• Containers for mixing‎‎
• Waste collection and storage‎‎
• Storing semi-finished items for further processing
  ‎‎Manufacturers may produce plastic buckets targeting specialty applications such as those used for storing paints. They can also target more general applications such as household usage where they can be used for several applications like holding water or storing pet food.‎‎

  Plastic type‎‎

  The bucket can be made out of PP, HDPE, LDPE, ABS or other plastic. The grade of the plastic used in the production of the bucket is also important. To buckets can be made out of HDPE however, the HDPEs could be of different molecular weight or polydispersity. This will reflect in their strength and durability.‎‎‎

  Storage and Usage environment

  ‎‎Where the plastic bucket is stored and used significantly affects the lifespan. A plastic that is frequently exposed to intense sunlight and heat might experience UV and thermal degradation faster than that stored at room temperature indoors. ‎‎Similarly, the stress the plastic is exposed to. A plastic bucket that is constantly used for heavy duty lifting of cement on a daily basis is more likely to experience structural failure than one that is used to store fertilizer and hardly gets moved.‎‎

  Design Parameters

  ‎These include parameters like shape, thickness, color, features (handles, covers, ribs), and labels. The shape and thickness of the bucket affects how stress is distributed. This consequently affects how well the bucket can resist impact and carry load.‎‎‎‎The color affects how the plastic absorbs radiation. Black plastic buckets will absorb more heat while a white one will reflect more heat. This determines how much heat penetrates the polymer structure causing thermal degradation. Different pigments at different concentrations are used to achieve certain colors. These often interact with the polymer differently and affect the mechanical properties.‎‎‎‎

Types of additives used in plastic buckets

‎The intended application of the plastic bucket is considered when determining the additives to use. The additives for buckets used for storing frozen yoghurts for example, will be different from those used for collecting harvested grains from the field.
‎
‎
‎The additives used in plastic buckets are more often a combination of more than one additive serving different purposes. The overall durability of the bucket is as a result of the combined effect of all the additives, the polymer and fillers used.
‎

‎BASF presents a portfolio of additives at Chinaplas 2026 in Shanghai. This range of additives is aimed at improving UV stability of polymers which includes HDPE and PP commonly used in plastic buckets manufacturing. The Valeras range of additives comprises of a number of additives working in synergy within a polymer compound to provide optimum protection from light, heat, moisture, and oxidation experienced by plastic products used outdoors.
‎

Pigment

‎Color of the plastic bucket is very important for marketing and branding. Some brands are identified with certain colors and consumers identify certain colors with attributes like cleanliness, edible or function. Because the pigments interact with the polymer, this may also affect the mechanical properties hence durability and Lifespan.
‎

Plasticizers

‎
‎Plasticizers improve the flexibility of the bucket. This improves the flexibility and strength and makes the bucket more resilient. Without plasticizers the bucket becomes brittle, especially when used at low temperatures.
‎

UV stabilizers

‎Exposure to UV from sunlight or other sources can cause plastic buckets to become brittle. This is a form of biodegradation where the secondary bonds between polymer chains get broken by UV radiation. This causes the plastic to weaken and fragment into small pieces. This leads to formation of microplastics. UV stabilizers are added to shield the plastic from this, a sort of "sunscreen" for plastics.
‎

Antioxidants

‎
‎Other than thermal or UV degradation, plastics degrade by oxidation. Antioxidants serve as scavengers of free radicals, preventing them from reaching the plastic. Example of antioxidants used in plastics manufacturing are Irganox 1010, Irganox 1076 and Lowinox CPL.
‎

Impact modifiers

‎
‎These are often specialised polymers that toughen the plastic and make it . durable and resistant to mechanical impact. An example is EPDM that is commonly used with polyethylene.
‎

Biocides

‎
‎Some plastic buckets like those used in food and pharmaceuticals may use biocides to prevent microbial degradation of the plastic. Examples of these are silver compounds that are known to have antimicrobial properties. Other than protecting the plastic from microbial degradation, the biocides may also be used with the intention to prevent microbes from contaminating the contents of the bucket. An example is where the buckets are being used for fermentation or storage of food items or pharmaceuticals.
‎

Conclusion

‎
‎Additives can significantly improve the durability and lifespan of plastic buckets. The type of additives used should be properly matched with the intended application of the plastic buckets to optimize cost and performance. In improving the durability and lifespan of plastic buckets, additives consequently improve their sustainability. The overall impact of additives on a plastic bucket is often the combined effect of all the additives present in the product. Therefore manufacturers ensure that the additives being used are working in synergy rather than having contradicting effects.
