Overwinter Greenhouse Plastic — Clear, Better Tear Strength, Higher Winter Light Transmission

Clear Overwinter Greenhouse Plastic for Winter Growing

Clear Overwinter Greenhouse Plastic, also called clear overwintering film, is a 5-layer co-extruded greenhouse film designed for seasonal plant protection during colder months. It helps reduce heat loss, protect crops from harsh winter conditions, and maintain strong natural light transmission inside the structure.

This clear overwinter film is stabilized for single-season use and offers better tear strength for hoop houses, greenhouses, and temporary winter covers. It can be cut to length for the structure, helping growers reduce gaps, improve coverage, and protect crops during winter production.

Use clear overwinter plastic when you want a simple winter cover that helps protect plants from wind, cold, and seasonal weather while still allowing useful sunlight to reach the crop.

Seasonal Protection for Winter Crops

Winter growing conditions can expose plants to cold air, wind, frost, and rapid temperature changes. Overwinter plastic helps create a more protected growing space by covering the structure and reducing direct exposure to harsh seasonal conditions.

This makes it useful for overwintering vegetables, ornamentals, perennials, nursery crops, and other plants that need protection during colder periods.

Clear Film for Strong Winter Light Transmission

The clear version is useful when growers want to maintain strong light penetration during the winter season. It allows natural sunlight into the greenhouse while still helping reduce heat loss from the covered structure.

For growers who need softer light or more light diffusion, overwinter plastic is also available in a white / diffused option.

Better Tear Strength for Seasonal Covers

Overwinter Plastic is designed with better tear strength to help it hold up through seasonal weather, installation tension, and normal winter greenhouse use. It is a practical choice for temporary and seasonal structures that need protection without the cost of a long-term greenhouse cover.

Cut-to-Length for Greenhouses and Hoop Houses

Overwinter Plastic is available in custom cut-to-length options so growers can match the cover to the structure. A better fit helps reduce waste, improve installation, and limit gaps that can allow heat loss or wind exposure.

When to Use Overwinter Plastic

• Seasonal winter crop protection
• Temporary greenhouse or hoop-house covers
• Nursery and ornamental crop protection
• Cold-weather growing and season extension
• Structures that need a single-season protective film
