Which plastic is best for buckets?

Plastic buckets are durable and practical tools used for various purposes. When it comes to choosing the right plastic for buckets, two common options stand out: HDPE (High-Density Polyethylene) and PP (Polypropylene). Both materials offer distinct characteristics that make them suitable for various applications. But, you might be wondering which one is better. Here’s a comparison of the characteristics of the two materials:


What is HDPE?

HDPE, or High-Density Polyethylene, is a versatile thermo plastic made from petroleum. It is known for its strength, durability, and resistance to chemicals, making it an ideal choice for various applications, including bucket manufacturing.

What is PP?

Polypropylene is another widely-used plastic that is known for its chemical resistance and high melting point. PP bucket are lightweight, strong, and can withstand high temperatures. They are commonly used in the chemical and pharmaceutical industries, and are also suitable for food and beverage storage.

What is a Plastic Bucket Made of?

Both HDPE and PP buckets are manufactured using plastic resin, which undergoes a melting and molding process to create the desired bucket shape. The plastic resin used in the production of these buckets is derived from either crude oil or natural gas. Through processing, the resin is transformed into a polymer that can be molded into different shapes and sizes, including buckets. This manufacturing process allows for the creation of durable and versatile buckets that meet the specific needs of various industries.

What is a Suitable Material for a Bucket?


HDPE and PP are popular choices for bucket manufacturing. While HDPE is commonly used in the United States, polypropylene (PP) buckets are more practical due to their affordability and durability.

PP buckets find widespread application in various industries globally, including the chemical, pharmaceutical, and food and beverage sectors. They are known for their safety, making PP the preferred choice as a plastic raw material for bucket production.


Is a Bucket Waterproof?

HDPE and PP buckets are both highly waterproof, making them suitable for storing liquids without the risk of leakage. However, it is crucial to understand that not all plastics offer the same level of water resistance. For instance, polycarbonate is a type of plastic that can be permeable to water, and therefore, it is not recommended for liquid storage purposes. When choosing a plastic bucket for liquid storage, it is important to opt for materials like HDPE and PP, which provide excellent waterproof properties to ensure the contents remain secure and free from leaks.

Are Plastic Buckets Safe?

Polypropylene (PP) is widely recognized as one of the safest plastic materials for bucket production. It possesses desirable properties such as recyclability, food safety compliance, and suitability for custom printing. PP buckets are considered a reliable and secure choice.

High Density Polyethylene (HDPE) buckets are also popular in the United States due to their safety and reliability. They meet stringent industry standards and offer excellent durability and chemical resistance.

However, it's crucial to be aware that certain plastics, such as PVC (Polyvinyl Chloride) and polycarbonate, can pose potential hazards and should be avoided for bucket applications. PVC, for example, may contain harmful additives like phthalates, while polycarbonate can release bisphenol A (BPA) under certain conditions. It's advisable to prioritize the use of PP and HDPE buckets for their known safety and reliability.

Are All Buckets Food Safe?

It's important to note that not all buckets are suitable for storing or transporting food. Only designated food-grade buckets should be used for such purposes. Food-grade pails are made from materials that have been deemed safe for direct contact with food, ensuring the preservation of food quality and safety.

Other Bucket Materials

Polyethylene Terephthalate (PET): PET buckets are lightweight, transparent, and possess excellent resistance to impact and chemicals. These materials are commonly used for packaging food and beverages.

Polyvinyl Chloride (PVC): PVC buckets are known for their durability and resistance to impact, chemicals, and temperature changes. However, PVC is not recommended for food packaging due to the potential release of harmful chemicals.

Polycarbonate: Polycarbonate buckets are one of the strongest and most impact-resistant types of plastic. They are commonly utilized in industrial applications but are not suitable for food packaging.

Acrylonitrile Butadiene Styrene (ABS): ABS materials are lightweight, durable, and resistant to impact and chemicals. They find common use in industrial applications.
