What is another name for stretch film?


Stretch film is also commonly known as:
Stretch wrap
Pallet wrap
Shrink wrap (incorrectly used, as shrink wrap requires heat to shrink)
Plastic film wrap
Wrap film
Bundling film
In clear stretch film factories, manufacturers may refer to it by its specific type, such as cast stretch film, blown stretch film, hand stretch film, or machine stretch film. Different industries use distinct terminology depending on application, but the core function remains the same: securing and protecting products during storage or transportation.

What is blown stretch film vs cast stretch film?


Blown stretch film and cast stretch film are the two main types produced in clear stretch film factories:
Blown Stretch Film:
Manufactured using a blown extrusion process
Higher puncture resistance and durability
More cling and better load containment
Slightly cloudy or hazy in appearance
Noisy when unwound
Cast Stretch Film:
Made using cast extrusion, where the film is rapidly cooled on rollers
Higher clarity, making it better for scanning barcodes
Smoother, quieter unwinding
Lower cost but less puncture-resistant
Less cling, requiring more wraps to secure a load
Both types are widely used in logistics, warehousing, and packaging, and clear stretch film factories produce them based on specific customer needs.

A clear stretch film factory supplies these users with high-clarity, durable films that allow barcode visibility, ease of use, and cost savings. Businesses that rely on stretch film value its protective, flexible, and economical properties, making it a critical packaging solution for modern supply chains.

Who invented stretch wrap?


Stretch wrap technology was developed in the 1970s as a solution for securing loads efficiently. The invention is credited to John W. Castanza, who pioneered the use of linear low-density polyethylene (LLDPE) in stretch film production. His innovation revolutionized the packaging and logistics industry, reducing reliance on rigid containment methods like strapping and shrink wrap.
A clear stretch film factory today builds on this innovation by improving film clarity, strength, and sustainability. Advancements include multi-layered films, high-performance stretch ratios, and biodegradable options.
The industry has evolved significantly, with automated wrapping machines optimizing efficiency and minimizing material waste. Stretch film remains an essential tool for securing products, reducing shipping costs, and improving warehouse operations. The continued innovation in stretch wrap materials ensures that businesses benefit from stronger, lighter, and more environmentally friendly packaging solutions.

Automotive & Metal Industry – VCI stretch films prevent rust on metal parts.
A clear stretch film factory serves these industries by producing films in different thicknesses, strengths, and specifications to match varied packaging needs. As global trade expands, stretch films play a crucial role in supply chain management, ensuring that products arrive intact and undamaged.

What is VCI stretch film?


VCI (Volatile Corrosion Inhibitor) stretch film is a specialized type of packaging material designed to protect metal components from rust and corrosion during storage and transportation. It contains VCI chemicals that release protective vapors, forming a molecular shield on metal surfaces without leaving residue.
A clear stretch film factory producing VCI film caters to industries such as automotive, aerospace, military, and metal manufacturing. This film is particularly useful for shipping machinery parts, tools, and industrial equipment over long distances or in high-humidity environments.
VCI stretch film combines the benefits of standard stretch film (protection from dirt, dust, and moisture) with corrosion prevention, eliminating the need for additional rust-prevention methods such as oil coatings. This enhances efficiency and cleanliness in packaging operations, making it a preferred choice for manufacturers dealing with iron, steel, aluminum, and other metal components.

What is the purpose of a stretch film?


Stretch film is primarily used for unitizing, protecting, and securing goods during storage and transportation. It prevents shifting, damage, and contamination while ensuring stability, especially for palletized loads.
A clear stretch film factory produces high-quality transparent films that allow easy identification of products and barcodes without the need to remove the wrapping. This is essential in logistics and retail industries where quick scanning and inventory checks are crucial.
Stretch film also serves as a protective barrier against moisture, dust, and UV exposure, making it ideal for industries such as food, pharmaceuticals, and manufacturing. Some variants include anti-static properties for electronic components and UV-resistant films for outdoor storage.
Companies benefit from using stretch film as it is cost-effective, lightweight, and highly stretchable, minimizing material usage while providing excellent load containment. This makes it a preferred choice for warehouse operations, shipping, and industrial packaging.

What is the alternative of stretch film?


Several alternatives to stretch film exist, catering to sustainability and functionality. Paper-based wraps, reusable pallet netting, strapping, and shrink film are commonly used depending on the application.
For companies aiming to reduce plastic waste, biodegradable stretch film made from plant-based materials offers a sustainable alternative. Recyclable polyethylene film with reduced plastic content is also gaining popularity. Another option is pallet wrap nets, which allow airflow while securing goods, making them ideal for agricultural or perishable shipments.
A clear stretch film factory may also offer pre-stretched films, which reduce material usage while maintaining strength. Water-activated tapes and reinforced kraft paper wraps are used in industries where plastic alternatives are preferred. Businesses are increasingly exploring these options to align with sustainability goals while ensuring product safety, efficiency, and compliance with environmental regulations.

What is stretch film made of?


Stretch film is primarily made of linear low-density polyethylene (LLDPE), a type of plastic known for its flexibility, durability, and stretchability. LLDPE is produced through polymerization using a catalyst, which enhances its elasticity and strength. The film is manufactured through either blown or cast extrusion processes. The cast method results in clearer and smoother film, while the blown method creates a stronger and more puncture-resistant material.
A clear stretch film factory uses high-quality raw materials to ensure excellent cling properties and load stability. Additives such as UV stabilizers, anti-static agents, or colorants may be included for specific applications. The clarity of the film is crucial for industries that require barcodes and labels to remain visible while securing their products. Manufacturers continuously innovate by developing eco-friendly alternatives, such as biodegradable and recycled-content films, to reduce environmental impact.
