FAQs about PLA Stretch Film

What is the difference between cling film and stretch film?

Cling film and stretch film serve different purposes, despite their similar appearance. Cling film, often called plastic wrap or food wrap, is primarily used in food packaging to preserve freshness and prevent contamination. Made from polyethylene or PVC, cling film has a thin, flexible texture and a self-adhesive quality that allows it to “cling” to surfaces without external pressure. This makes it ideal for wrapping food items directly or covering dishes and containers. On the other hand, stretch film is a thicker, more durable material used mainly in industrial and commercial applications. It is designed to wrap and secure large loads, like pallets, for safe transport and storage. Stretch film is typically made from linear low-density polyethylene (LLDPE) and has high stretchability and tensile strength, enabling it to keep items stable and protected during shipping. Unlike cling film, stretch film does not self-adhere but instead requires manual or machine application to achieve a tight, secure wrap. In short, cling film is ideal for household food preservation, while stretch film is best suited for securing heavy-duty industrial loads.

What is the difference between stretch wrap and stretch film?

The terms “stretch wrap” and “stretch film” are often used interchangeably, but they both refer to materials used for securing items, particularly during transport. Stretch film is the material itself, usually made from linear low-density polyethylene (LLDPE) and designed to be flexible, elastic, and highly stretchable. It can be applied by hand or machine, depending on the application. Stretch film typically comes in large rolls and is available in various thicknesses, depending on the type and weight of the load it needs to secure. Stretch wrap, however, is more about the application process rather than the material. It refers to the action of wrapping items with stretch film to create a secure hold around pallets or bundles, stabilizing them for storage or transport. In short, stretch film is the actual plastic film, while stretch wrap describes the process of wrapping items with the stretch film material. Both terms are closely related, with stretch wrap focusing more on the technique and purpose of application.

What is the difference between blown film and stretch film?

Blown film and stretch film differ in production method, properties, and applications. Blown film is produced by blowing heated plastic through a circular die, creating a bubble that is then flattened and wound into rolls. This method gives blown film unique characteristics, such as high puncture resistance, durability, and a rough texture. Blown film is often used in applications that require greater toughness, such as in heavy-duty bags, liners, and some types of stretch wrap. In contrast, stretch film is specifically designed to stretch around items and secure them, typically in palletizing. Stretch film is produced using the cast extrusion process, where melted plastic is forced through a flat die and cooled immediately, resulting in a smooth, clear, and highly stretchable film. While both blown film and stretch film can be used for securing products, blown film is generally less stretchable and is used in applications requiring a more rigid, puncture-resistant film, whereas stretch film excels in applications where flexibility and high stretch are required.

What material is used for stretch film?

Stretch film is primarily made from linear low-density polyethylene (LLDPE), a type of plastic known for its flexibility, durability, and elasticity. LLDPE provides the perfect combination of strength and stretchability, allowing the film to secure and stabilize products efficiently without tearing or losing hold. The material’s elasticity is essential for stretch film, as it enables the film to stretch and conform to the shape of the items it wraps, creating a tight, secure hold. In addition to LLDPE, some stretch films may contain additives to improve specific qualities like UV resistance, puncture resistance, or color. These properties can enhance the film’s performance in particular environments or applications, such as outdoor storage or heavy-duty wrapping. Stretch film materials are chosen to balance the need for flexibility and tensile strength, making it suitable for both hand-applied and machine-wrapped applications.
