PP vs PET Strapping: Selecting the Best Packaging Solution

Strapping or bundling is an important step in the packaging process. It involves securing items or bundles together by applying a strap. It is to ensure safe transportation and storage of the goods. Strapping makes it easy to handle the bundles of products and stack them in proper order. 

Strapping materials used are Polypropylene (PP) and Polyethylene Terephthalate (PET).  

What is PP Strapping? 

Polypropylene (PP) strapping is a lightweight strap used for lightweight packages as it has moderate tensile strength. Due to its high elongation, it is flexible and easy to use. It has limited resistance to extreme temperatures and hence can’t be used in hot conditions. It is cheaper as compared to PET strapping. PP strapping is used in industries such as food and beverage, textiles, and paper products. 

Advantages of PP Strapping: 

• It can handle light to medium loads and hence cost-effective solution for small businesses. 

• It is flexible and hence it is easy to use for strapping.  

• It is recyclable and is an environmentally sustainable option.  

Disadvantages of PP Strapping: 

• Due to its lower tensile strength, it is not suited for heavy-duty applications. 

• It can’t endure extreme temperatures and UV exposure. 

• It could stretch over a period of time and it could lose its tension and may impact the safety of the goods. 

What is PET Strapping? 

Polyethylene Terephthalate (PET) strapping has a high tensile strength and is best suited for heavy-duty applications. It has lower elongation and hence it has less stretch. So, it is often rigid in its application. However, it is a strong and durable polymer and is resistant to impact and high temperatures. Due to its strength and durability, PET strapping is comparatively in the high price range. It is utilized in industries like construction, automotive, and metalworking. 

Advantages of PET Strapping: 

• It has excellent tensile strength to secure heavy loads. 

• It is durable and withstands temperature fluctuations and UV exposure. 

• It has low elongation and does not lose tension over time. 

• It is recyclable and hence an eco-friendly option. 

Disadvantages of PET Strapping: 

• Due to its strength and durability, it is more expensive than PP straps.  

• It is challenging to handle it in certain applications due to its low flexibility. 

• It needs specialized tools for strap application and removal. 

How to select the Best Packaging Solution?

PP strapping is the best choice when: 

• You can use it for light to medium loads that do not require high tensile strength.  

• If you are looking for a cost-effective packaging solution, then PP is the best choice. 

• The application of PP strapping is for indoor environments with moderate temperature conditions. 

PET strapping is the preferred option when: 

• You need to secure heavy, palletized loads that require high tensile strength. 

• If you need to ship heavy pallets that will be exposed to outdoor conditions which include high temperature and UV light, then PET strapping is the best option. 

• You want the strapping to maintain tension over time and be durable to handle rough transportation and storing conditions. 

• If your brand promotes environmental sustainability, then you need to opt for PET strapping due to its recyclability.  

Conclusion 

The right strapping material is vital to ensure the safety and integrity of the goods, so you need to consider the advantages and disadvantages of both the strapping material and make an informed decision.
