How Is PET Plastic Different from Other Plastics

There's no denying that plastic plays a significant role in the manufacturing and packaging industries. Its versatility allows it to be moulded into various shapes and sizes, offering numerous useful properties. However, as the world takes action against the environmental impact of plastic, many companies are revising their operations to implement sustainable practices.

At Petainer, we provide innovative packaging solutions specifically designed to fit into the circular economy. Our products are crafted to be recycled, reducing waste leaking into the environment. PET plastic is a sustainable packaging option and the leading type of plastic used for beverage bottles, owing to its excellent chemical resistance to organic materials and water, and a high strength-to-weight ratio.

In this article, we'll explore what exactly PET is, assess its benefits, and compare it to other plastic types.

What is PET?

PET, or polyethylene terephthalate (also known as PETE), is a strong, stiff synthetic material that is part of the thermoplastics family. This means it can be heated, melted, and cooled into many shapes and sizes. Made from a combination of ethylene glycol and terephthalic acid, derived from petroleum and natural gas, PET is popular within the manufacturing sector for producing bottles and jars.

Almost every plastic bottle is made from PET. It's suitable for a range of beverages, including carbonated drinks, still and dilutable drinks, fruit juices, and bottled water.

Key Properties of PET:

• Chemical Resistance: Offers a protective barrier against CO₂ and light, repels microorganisms, and is EU/NSF/FDA tested and approved.
• Clarity and Strength: Has a clear appearance similar to glass once set, combined with high strength, making it both attractive and durable.
• Safety: PET is shatterproof, known as the 'safe' plastic, and does not contain Bisphenol-A (BPA), a chemical that can be harmful in large quantities.
• Versatility: Its thermoplastic nature allows it to be moulded into various shapes and sizes, suitable for different packaging needs.
• High-Pressure Processing (HPP): PET is so strong that it can undergo HPP, a heat-free form of pasteurisation.

How is PET Different from Other Plastic Types?

PET stands out from other plastics due to its unique combination of properties and sustainability credentials.

Comparison of PET with Other Plastics:

Is PET More Eco-Friendly Than Other Types of Plastic?

Yes, PET is considered more eco-friendly compared to many other plastics. Here's why:

• 100% Recyclable: PET can be recovered and recycled into new products repeatedly, reducing waste and conserving resources.
• Lower Carbon Footprint: Uses less energy during manufacturing, helping suppliers reduce overall energy consumption.
• Lightweight: Allows companies to transport large quantities more efficiently, reducing carbon emissions from transportation.
• Renewable Energy Production: At Petainer, we produce PET bottles in factories powered by renewable energy, boosting the product's sustainability credentials.
• Circular Economy Fit: Designed to be part of a closed-loop system, supporting sustainable practices.

Life Cycle of PET

The life cycle of a PET product is designed to be circular, with minimal waste if consumers dispose of it correctly.

1. Production: PET is manufactured from raw materials derived from petroleum and natural gas.
2. Usage: Used for packaging beverages and other goods due to its safety and versatility.
3. Collection: After use, PET products are collected through recycling programs.
4. Recycling: Cleaned and processed into recycled PET (rPET) pellets.
5. Reproduction: rPET is used to make new bottles and containers, reducing the need for virgin materials.

Recycled Content and the Circular Economy

• Recycled PET (rPET): PET products can be produced using recycled PET, reducing reliance on virgin materials and lowering carbon emissions.
• Our Commitment: Petainer's one-litre refillable PET bottles are made with 30% recycled content, offering an 81% reduction in carbon compared to refillable glass bottles.
• 100% Recycled Options: Some of our designs can be produced using 100% recycled content, eliminating virgin plastic and saving up to 75% in carbon emissions.
• Closed Loop Potential: PET's ability to be recycled multiple times contributes to a circular economy, minimising environmental impact.

Is PET Safer Than Other Types of Plastic?

PET is known for its safety and hygiene:

• BPA-Free: Does not contain Bisphenol-A (BPA), unlike some other plastics. BPA can interact with the body's endocrine system, potentially causing negative health effects.
• Non-Reactive: Doesn't react with food or liquids, ensuring contents remain safe to consume.
• Shatterproof: Unlike glass, PET doesn't shatter when broken, reducing the risk of injury.
• Regulatory Approval: Approved by EU, NSF, and FDA authorities for food and beverage packaging.
• Microbial Resistance: Repels microorganisms, maintaining the purity of the contents.

Additional Benefits of PET

• Economic Advantages: Cost-effective to produce and transport, making it an economical choice for businesses.
• High Strength-to-Weight Ratio: Strong yet lightweight, ideal for various packaging needs.
• Versatile Design Options: Can be moulded into a wide array of shapes and sizes, offering flexibility in product design.
• Barrier Properties: Excellent at preventing gas and moisture transmission, preserving product quality.
