What is Shrink Film? Exploring Common Materials

Shrink film, commonly referred to as shrink wrap, is a versatile packaging material widely used across various industries to protect products, enhance their visual appeal, and provide tamper-evident seals.

In this blog, we'll dive into some of the most common types of shrink film materials, including PVC, POF, OPS, PE, PET and PETG.

PVC Shrink Film

  • Characteristics: PVC shrink film has excellent transparency, good processability and high shrinkage rate. Due to its ability to closely fit products, it is widely used in the packaging of electronic products, toys and CDs.
  • Drawbacks: PVC releases harmful fumes during the sealing process, which can cause health and environmental impacts. PVC shrink film is soft when used in summer, but will harden in winter.

 POF Shrink Film

  • Characteristics: POF is a soft and environmentally friendly shrink film that does not release toxic gases during the combustion process. It can come into direct contact with food. It has high transparency, strong sealing and excellent puncture resistance.
  • Benefits: POF shrink film is versatile, capable of withstanding extreme temperatures, and is suitable for both manual and automated packaging lines.

OPS Shrink Film

  • Characteristics: OPS shrink film has high shrinkage rate and strength. It can fit tightly with containers of various shapes. It can not only print exquisite patterns, but also meet the use of various novel packaging containers of different shapes. It has excellent transparency and gloss, enhancing product visibility.
  • Application: It is commonly used for labeling and packaging applications in the beverage and pharmaceutical industries.

PE Shrink Film

  • Characteristics: PE shrink film is a durable, cost-effective material that provides excellent tear resistance. It’s commonly used for bundling multiple products together, such as in the packaging of beverages.
  • Versatility: PE is available in various densities (LDPE, MDPE, HDPE), each offering different levels of strength, flexibility, and shrinkage properties.

PET Shrink Film

  • Characteristics: PET shrink film offers high clarity, excellent printability, and strong mechanical properties. It’s widely used in labeling applications, providing a premium look and feel to packaged goods.
  • Sustainability: PET is fully recyclable, reducing negative impact on the environment.

PETG Shrink Film

While the different shrink films mentioned above each have their advantages, we are proud to introduce the advanced PETG shrink film. PETG combines the excellent properties of PET with enhanced flexibility and impact resistance, making it an ideal choice for various packaging applications.

Why Choose PETG?

  • Superior Clarity: PETG offers exceptional clarity and gloss, ensuring your products stand out on the shelves.
  • Enhanced Durability: With its robust mechanical properties, PETG is less prone to tearing and punctures, providing reliable protection for your products.
  • Environmentally Friendly: PETG is fully recyclable, aligning with growing consumer demand for sustainable packaging solutions.
  • Versatility: PETG can be used across various industries, from food and beverage to pharmaceuticals and consumer goods.
