Differences between PVC shrink film, polyolefin and polyethylene

Packaging plays a key role in the protection and presentation of products. However, choosing the right shrink film can be an extremely important issue for many businesses. The three main types of shrink film, PVC, polyolefin (POF) and polyethylene (PE), have different properties and applications that are worth knowing in order to make an informed choice. In this article, we look at the main differences between these three types of shrink film to help you make the best decision for your packaging needs.

What is shrink film?

Shrink film is an integral part of today's packaging processes, providing not only protection but also an aesthetically pleasing appearance for products. It is a transparent plastic film used to package a wide range of products. It is characterised by the fact that, when exposed to temperature, it shrinks, wrapping itself around the item being packaged. The shrinking process involves heating the film, which causes it to shrink, providing a perfect fit to the shape and size of the product being packaged.

Shrink film parameters:

Lightweight and easy to process: Shrink film is extremely lightweight and easy to handle, making the packaging process easier and production more efficient.
Excellent optical properties: Thanks to its excellent optical properties, the shrink film provides clarity and transparency, allowing products to be presented in a way that is attractive to customers.
Relatively low shrink temperature: The shrink film reacts to relatively low temperatures, minimising the risk of damage to the packaged product during the shrinking process.

POF shrink film

Polyolefin shrink film (POF) is a true gem among packaging materials. Considered a premium material, it stands out not only for its excellent strength and clarity, but also for a number of other benefits that make it the ideal choice for aesthetically pleasing product packaging.

POF film parameters:

High tensile strength: One of the key features of POF film is its exceptional tensile strength. This makes packaging made from POF film extremely durable and resistant to damage, which protects the packaged products during transport and storage.
Excellent transparency: Another advantage of POF film is its excellent transparency. It makes products packaged in POF film look particularly attractive and professional, which increases their appeal to customers.
Food safety: An important advantage of POF film is also its food safety. By meeting stringent norms and standards for food contact materials, POF film ensures that packaged products are safe to eat, which is of key importance particularly in the food industry.
Protection and presentation in one: with its combination of high strength, excellent transparency and food safety, POF shrink film is the ideal solution for manufacturers who care about both protection and attractive presentation of their products.

That is why POF shrink film is not only a packaging material, it is also a guarantee of protection, aesthetics and safety. Thanks to its unique properties, it is the perfect choice for anyone wishing to give their products not only the best protection, but also an attractive presentation.

PE shrink film

Polyethylene (PE) shrink film is an indispensable solution for packaging heavier products. Compared to other types of film, PE film is relatively thicker, making it the ideal choice where exceptional packaging strength and durability are needed.

PE film parameters:

Increased strength and durability: This is its main advantage, thanks to which packaging made of PE film is able to protect even the heaviest products from damage and loss of quality, which is of key importance, especially in the case of transport and storage.
Approved for food contact: Other important strengths of PE film are its compliance with food contact standards. This means that PE film is safe for use with food products, which is extremely important, especially for packaging intended for the food industry.
Perfect for packaging heavy products: Thanks to its thicker structure and increased strength, PE shrink film is an excellent choice for packaging heavy products such as building supplies, metal goods or other items with a high weight and volume.

Differences between shrink and stretch film

It is also worth highlighting the differences between shrink film and stretch film, which are often confused with each other. While shrink film shrinks when exposed to temperature, providing tight and damage-resistant packaging, stretch film is flexible and is mainly used to secure goods during transport and storage, preventing them from moving.
PE shrink film is a reliable solution for packaging heavier products, providing not only strength and durability, but also compliance with food contact standards. The differences between PE film and stretch film are important, as each has its own unique properties and applications that need to be considered when choosing the right packaging material.
Choosing the right shrink film can have a significant impact on the protection and presentation of your products. Understanding the differences between PVC film, polyolefin and polyethylene will help you make the best decision for your packaging needs.
