Breathable Stretch Film.

Improving product protection, reducing condensation and enhancing supply chain efficiency with innovative pallet wrapping solutions.

In manufacturing, warehousing and logistics, protecting products during storage and transportation is essential. However, conventional pallet wrapping can sometimes create an unexpected challenge: trapped heat and moisture.

When products are wrapped in traditional, non-perforated stretch film, moisture and warm air can become trapped inside the packaging. This can lead to condensation, potentially causing product deterioration, corrosion, mould growth, damaged labels and unnecessary product waste.

For businesses handling fresh produce, food products, beverages and temperature-sensitive goods, these challenges can have a significant impact on product quality, operational efficiency and profitability.

CHETO Engineering Ltd. can offer breathable stretch film solutions designed to address these challenges, providing an alternative to conventional pallet wrapping materials.

What is breathable stretch film?

Breathable stretch film is an innovative pallet wrapping solution featuring a specially engineered perforation pattern that allows air to circulate through wrapped pallet loads.

Unlike conventional solid stretch film, the perforations allow excess moisture and warm air to escape while maintaining the containment and stability required during handling, storage and transportation.

This provides an effective balance between securing palletised products and allowing the ventilation needed for certain applications.

The challenges of conventional stretch film

Traditional stretch film creates a sealed layer around palletised goods. While this provides containment and protection, it can also prevent moisture from escaping.

This can result in several operational problems:

• Condensation: Moisture builds up inside the wrapped pallet.
• Product deterioration: Fresh produce and other sensitive products may be exposed to excessive moisture.
• Corrosion: Metal components, including beverage can crowns, can be affected by moisture.
• Label damage: Condensation can cause labels to peel or become damaged.
• Cooling inefficiencies: Trapped heat and moisture can slow down cooling processes.
• Product rejection: Damaged or compromised goods can result in rejected shipments and financial losses.

For manufacturers and distributors, these issues can create additional costs throughout the supply chain.

How breathable stretch film can make a difference

Engineered breathable stretch film addresses these challenges through controlled perforations and reinforced construction.

1. Improved airflow

The perforations allow air and moisture to move through the film, helping reduce condensation around palletised products.

2. More efficient cooling

Improved airflow can help products reach their required temperatures more quickly during cooling and blast-freezing processes.

3. Better product protection

By helping to reduce moisture accumulation, breathable film can minimise problems such as corrosion, mould and label deterioration.

4. Maintaining load stability

Reinforced construction helps maintain containment force, securing palletised goods during handling, storage and transportation.

5. Flexible application

Breathable stretch film is available in both machine and hand-applied grades, making it suitable for a variety of packaging operations.

Why the quality of perforated stretch film matters

Not all perforated stretch films deliver the same performance.

The design, size and distribution of the perforations are important factors in determining how effectively air can circulate through the wrapped load.

Some conventional perforated films may have holes that do not open sufficiently during application, potentially restricting the airflow they are intended to provide.

High-quality breathable stretch film is engineered to ensure that ventilation remains an integral part of the packaging solution while maintaining the required load containment.

Getting the best performance from breathable stretch film

Correct application is essential to achieving the intended performance.

A typical wrapping approach includes:

• Starting with two revolutions around the pallet base to secure the load.
• Spiralling upwards with approximately 20–30 mm overlap.
• Applying two revolutions around the top of the load.
• Using sufficient tension to secure the goods without crushing or damaging products.
• For heavy or unstable loads, spiralling back down to provide additional stability.
• Finishing with a clean cut and securing the film tail.

The correct wrapping method will depend on the product, pallet configuration, weight and transportation requirements.

A smarter approach to packaging efficiency

Packaging should not simply be viewed as a consumable expense. It plays an important role in product protection, operational efficiency and overall supply chain performance.

By addressing condensation and ventilation challenges, breathable stretch film provides businesses with an opportunity to improve their pallet wrapping processes.

For companies handling fresh produce, food and beverage products, frozen goods and other moisture-sensitive materials, choosing the right stretch film can make a meaningful difference.

The potential benefits extend beyond the packaging itself, helping businesses maintain product quality, reduce avoidable waste and improve logistics operations.
