A guide to polythene and shrink film

In the world of packaging, versatility and durability are key factors.

Polyethylene (polythene) and shrink film have emerged as essential materials for packaging companies across retail and industrial sectors. Having a comprehensive understanding of these materials is vital for businesses aiming to implement cost-effective and resilient packaging solutions. In this guide, we will delve into the realm of polythene packaging and shrink film, examining their applications, advantages, and the distinguishing features that render shrink film a valuable option.

What is polythene?

Polyethylene plastic, often referred to as polythene, stands as the most extensively utilized plastic globally. Belonging to the polyolefin family of plastic resins, it primarily comprises ethylene, a hydrocarbon compound. Available in diverse forms, including low-density polyethylene (LDPE), high-density polyethylene (HDPE), and linear low-density polyethylene (LLDPE), each variant presents distinct properties suitable for various applications. Low-density polyethylene (LDPE) finds widespread use in numerous packaging products, such as carrier bags, stretch film, and bubble wrap. Its versatility and flexibility make it an ideal choice for these applications, offering reliable protection and ease of use in packaging solutions.

What is shrink film?

Shrink film, also known as shrink wrap, is a plastic packaging material that contracts or shrinks when subjected to heat. This material is utilized for various purposes, including packaging, presentation, and ensuring tamper resistance, across both retail and industrial environments. Shrink wrap can be manufactured from polyethylene (polythene) as well as other plastics like polyolefin. Its ability to conform tightly to the shape of the item being packaged makes it a popular choice for a wide range of applications. Whether used to bundle products together, protect goods during transportation, or enhance the appearance of retail packaging, shrink film offers versatility and reliability in packaging solutions.

Types of polythene packaging products
