Types of Stretch Film

Stretch film comes in various types. Each one offers unique benefits based on the intended use. Below are the most common types:

• Hand Stretch Film

  Many people like hand stretch film because it is simple to use. Workers can apply it quickly by hand, wrapping pallets or items in a tight and secure manner. In small packaging and shipment preparation, hand stretch film is perfect. It also works well for lighter loads that do not need machine application.

• Machine Stretch Film

  They specifically designed machine stretch film for automated wrapping systems. High-volume operations usually prefer this due to its consistent application and high adhesion. A machine usually applies the film in warehouses and distribution centers where wrapping speed is essential.

• Casting Stretch Film

  Casting stretch film comes into being after a process of casting extrusion. This film provides a shiny appearance and clear visibility, which is outstanding. It is also thin and lightweight. Many users have found this type of film helpful when they want flexible and tear-resistant packaging.

• Blown Stretch Film

  Around very high loads, users advise using blown stretch film. It gives a thicker and sturdier wrap than many other films. Blown stretch film also has excellent stretch resistance. These features improve protection during shipment. Several manufacturers like to use this film for products that require more wrapping strength.

• Pre-Stretched Film

  Users have already stretched pre-stretched film before packaging it. This stretching reduces its elasticity, which makes it easier to handle. Buyers use this type of film where a tighter wrap and minimal film usage is necessary. They mostly benefit from it in manual or machine processes.

Design of Stretch Film

Several factors influence the design of stretch film. Below are the factors:

• Thickness

  The thickness of stretch film affects its strength and stretchability. Retailers usually measure this parameter in mils. Most hand stretch films fall within the 60 to 90 mil range. On the other hand, machine films can go up to 120 mils. Thicker films usually offer better puncture resistance and durability. However, they also become heavier and harder to handle. Films with lesser thickness provide easier handling. However, they may not give enough strength for heavy or irregularly-shaped loads.

• Clarity and Transparency

  Manufacturers design many stretch films to have high clarity for quick identification and inspection of wrapped items. They also add transparent films to protect goods from uv lights. That helps prevent damage to sensitive materials. Using opaque stretch film provides additional security. This feature deters theft and protects items from unwanted visibility.

• Edge and Core Design

  Many stretch film rolls feature specific core and edge designs. These designs improve film delivery and handling. Manufacturing companies usually make most hand rolls using 1-inch cores. On the other hand, machine stretch films have 3-inch cores for automatic dispensers.

• Grip and Handle Options

  A large number of manufacturers design the handles of stretch film dispensers with comfort and control in mind. Options include padded grips, trigger-style handles, and adjustable tension controls. Those features improve wrapping consistency and reduce operator fatigue.

• Custom and Color Stretch Films

  The purpose of custom stretch films is to meet certain brand packaging requirements. Moreover, they enable companies to personalize their packaging solutions. Color stretch films perform more than this function since they offer load identification and tamper evidence. Often, they manufacture these films in distinctive patterns or textures that improve grip and functionality.

Uses of Stretch Wrap

People use stretch films for several purposes. Below are the use cases:

• Protection of Items During Shipping

  Companies usually wrap products with stretch film before dispatching them. The tight sealing that comes with this process minimizes movement during transportation and reduces the risk of damage. Besides, it protects items from moisture and other environmental elements. These factors make it an integral part of the shipping process. Companies have to wrap their items to maintain their integrity and quality by the time they reach their destination.

• Warehouse Storage

  In warehouses, manufacturers use stretch film to stack and store items efficiently. A stretch-wrapped pallet takes up less space than individual items. It also makes inventory management more efficient. Furthermore, it offers a simple system of tamper evidence. This feature allows for easy monitoring of product security while in storage.

• Load Stabilization

  At construction sites, contractors have to deal with various materials. They often need to ensure these materials remain stable when stacked. Using stretch film brings several loads together to create a unified mass. This situation reduces the chance of toppling over during movement. Therefore, it becomes an essential tool for on-site safety.

• Retail Packaging

  In retail settings, retailers apply stretch film to bundle products. This technique makes handling and merchandising easy. For instance, wrapping groups of items together simplifies restocking on shelves. Also, it improves the items' overall presentation. Further, stretch film deters theft in retail stores. It offers an extra layer of security around products.

• Use at Home

  People widely use stretch film at home as well. They normally wrap fragile items, including dishes or decorations, for storage or moving purposes. Also, they use it to wrap food. This method provides an airtight seal that keeps leftovers fresh in the refrigerator. The versatility of stretch film for protection and preservation makes it a common choice for individuals who need to store or transport items.

Specification of Stretch Film

Below are some key specifications for stretch films:

• Length and Width

  The standard width of stretch film ranges from 12 to 18 inches. On the other hand, the length varies. For instance, a typical roll for hand wrap extends around 1,500 feet. But a machine wrap can go up to 6,000 feet in length. The sizes users choose usually depend on the size of the load and the type of wrap required. Users need to consider this aspect to ensure they have the proper width and length for their usage.

• Elongation and Stretch Percentage

  Manufacturers have to ensure that the stretch film has a high elongation percentage. This feature allows the film to extend significantly without tearing. Also, optimal elongation ensures a tight wrap around the load. Users also prefer films with consistent stretch memory. This quality enables the film to return to its original shape after use.

• Tensile Strength

  Tensile strength is the key issue when it comes to load, weight, and size. Look for films with higher tensile strength. It results in safer transport for heavier items. Furthermore, films that come with balanced tensile strength in both directions offer more stability to irregular-shaped loads. This quality minimizes the risk of slipping or toppling.

• Core Size and Type

  Hand-held stretch films normally have 1-inch cores. On the other hand, machine films usually have 3-inch cores. This feature ensures compatibility with the dispensers. Depending on the type of application, films with either plastic or cardboard cores are more suitable. Users should replace plastic-core films easily in production environments.

• Cling Properties

  The best cling properties maintain the film's layers, tightly without the need for adhesive. One way of achieving this is through the use of built-in cling technology. It helps manufacturers reduce waste by eliminating the need for additional adhesives. Also, good cling properties ensure the load remains securely wrapped until it reaches its destination.

How to Choose Stretch Film

When buying stretch films, there are several factors business owners need to consider. Here are some of them:

• Type

  Buyers can choose from two main types of stretch films, manual and machine-based. They normally use the former for low-volume packaging tasks. In contrast, they use the latter for high-speed packaging. Therefore, choosing the right type is critical for achieving the desired wrapping performance.

• Material

  Most manufacturers make stretch films using linear low-density polyethylene (LLDPE). They prefer this material since it provides a good balance between strength and elasticity. It also conforms to irregular loads, which gives them more security during transportation. Therefore, they should consider the films' material properties to avoid compromising quality.

• Thickness

  Normally, the thickness of the stretch film affects the stretch and strength. Most films range from 50 to 120 mm in thickness. Buyers who need lightweight protection prefer the former. On the other hand, those requiring heavy-duty packaging usually go for the latter. Therefore, they should choose films with consistent thickness for uniform applications.

• Cling

  Manufacturers treat some stretch films with a cling agent. This feature enhances self-adherence between layers. It also eliminates the need for extra adhesives. So, to minimize wastage, business owners should look for films with built-in clinging properties. This property ensures that the film lays flat on itself for easy application.

• Color and Clarity

  Some buyers use opaque or colored stretch films for security and load identification. Others, however, prefer clear films for product visibility. They should, therefore, consider the film's color based on the intended application. Retail environments may require clear films for product visibility. However, warehouses might need opaque films for security purposes.
