Transparent Underlayer Film

What Is Transparent Underlayer Film?

Transparent underlayer film, also known as oxygen barrier underlay film or cling film for silage, is a thin, highly flexible agricultural film applied directly onto the silage before the main cover film is installed.

Thanks to its excellent elasticity and surface conformity, the film closely follows the contours of the forage pile, minimizing trapped air pockets and creating a tighter seal than traditional single-layer covering systems.

Key Benefits of Transparent Underlayer Film

Superior Oxygen Exclusion

Oxygen is one of the main causes of silage spoilage. When air penetrates the silage mass, it can trigger unwanted microbial activity, resulting in heating, mold growth, and nutrient loss.

Transparent underlayer film:

• Adheres tightly to the forage surface
• Reduces air pockets between silage and cover film
• Minimizes oxygen infiltration
• Creates a more stable anaerobic environment

The double-layer covering solution effectively reduces mold growth and nutrient loss, improves silage quality, and provides livestock farms with a more stable, safe, and nutritionally rich feed storage solution.The result is improved fermentation and better feed preservation.

Reduce Dry Matter Losses

Every percentage of dry matter lost during storage represents wasted feed and reduced profitability.

By improving airtightness, transparent underlayer film helps:

Preserve valuable nutrients

Reduce surface spoilage

Lower storage losses

Increase feed recovery rates

This allows livestock producers to make better use of every ton of harvested forage.

Improve Silage Fermentation

A well-sealed silage pile encourages the rapid development of beneficial lactic acid bacteria.

Benefits include:

Faster pH reduction

Improved fermentation quality

Better feed stability

Enhanced palatability for livestock

Higher-quality silage contributes directly to improved animal performance and feed efficiency.

Suitable for Multiple Silage Types

Transparent underlayer film is widely used for:

Corn silage

Grass silage

Alfalfa silage

Ryegrass silage

Whole crop silage

Dairy and beef forage storage

Whether storing forage in bunker silos, drive-over piles, or clamp silos, underlayer film provides an effective additional protection layer
