Shrink & Stretch Hooder Film: An Overview

Shrink and stretch hooder films are specialized polyethylene (PE) films used for securing and protecting palletized loads during storage and transportation. Both films offer unique benefits depending on the application requirements, such as load stability, environmental exposure, and cost-effectiveness.

Shrink Hooder Film

Shrink hooder film is a heavy-duty plastic film that is applied over palletized goods and heat-shrunk to create a tight, form-fitting protective layer. It provides excellent load stability and protection against dust, moisture, and tampering.

Key Benefits of Shrink Hooder Film:

• Superior Load Stability:Tightens securely around the load after heat application.
• Weather Resistance:Provides excellent protection against rain, dust, and UV exposure.
• Tamper-Evidence:Any unauthorized access to the load is easily noticeable.
• Customization:Available in clear or printed options for branding and identification.

Common Applications:

• Building materials (cement, bricks, insulation)
• Beverage and food industries
• Chemical and agricultural products
• Industrial goods requiring long-term outdoor storage

Application Process:

1. The film is placed over the load.
2. Heat is applied using a shrink tunnel or gas-powered heat gun.
3. The film shrinks tightly, conforming to the shape of the load.

Stretch Hooder Film

Stretch hooder film is a high-stretch elastic film designed to stretch over a palletized load without requiring heat. It provides a strong hold and flexibility while offering significant cost and energy savings compared to shrink hooding.

Key Benefits of Stretch Hooder Film:

• No Heat Required:Reduces energy costs and enhances safety during application.
• Elastic Memory:The film stretches and contracts to hold the load securely.
• Puncture and Tear Resistance:Ideal for heavy and irregularly shaped loads.
• Sustainability:Often available in thinner, high-performance formulations to reduce plastic use.

Common Applications:

• Consumer goods and electronics
• Automotive and industrial parts
• Distribution centers and warehouses
• Retail-ready packaging requiring high visibility

Application Process:

1. The stretch hood is pulled over the load using automated machinery.
2. The film contracts naturally to secure the load in place.

Shrink vs. Stretch Hooder Film: Key Differences

Feature Shrink Hooder Film Stretch Hooder Film

Application Process Requires heat No heat needed

Load Stability Excellent after heat shrinkage Strong elastic hold

Energy Consumption Higher (heat application) Lower (energy-efficient)

Cost Higher due to energy use Lower operational costs

Protection Level Superior weather protection Good weather and dust protection

Flexibility Less flexible Highly flexible

Choosing between shrink and stretch hooder film depends on factors such as the type of products being packaged, storage conditions, transportation requirements, and operational budget.
