Agricultural & Greenhouse Plastic Films

All greenhouses are covered in agricultural or greenhouse plastic films of one kind or another. The type of greenhouse plastic film cover you choose depends on what you are growing and what you are trying to accomplish with agricultural greenhouse films. Pro-Tect offers a variety of greenhouse plastic films that can help with light filtration, light deprivation, or temperature and moisture control to suit your gardening and crop needs.

Buy Greenhouse Plastic For Your Specific Needs

Growers across the country have different greenhouse plastic films and covers that produce the best yields and harvests in their indoor growing areas. Whether you are a commercial grower or a hobbyist, we have agricultural or greenhouse plastic films that will work for you.

Benefits of Agricultural Plastic Films

  • Extended Growing Seasons
    Wrapping a greenhouse in agricultural plastic film is a common strategy used to extend the growing season of crops or plants, while also increasing seasonal yields.

  • Black & White Reflective/Absorptive Films
    Black and white reflective and light-absorbing agricultural plastic film is used for crop control management. The white side is highly reflective and directs light away, while the black side absorbs light, keeping heat and light away.

  • Temperature & Humidity Control
    Our heat shrink wrap can help manage both temperatures and humidity levels for improved growing conditions in agricultural environments.

Installation Considerations

  • Thermal Expansion & Contraction
    Thermal greenhouse plastic films will expand and contract as temperatures increase and decrease. Typically, dimensional changes of 1 to 12 inches in length and 1 to 4 inches in width can be expected under field conditions.

  • Variability in Expansion
    The actual expansion and contraction will vary depending on the width, gauge, formulation, and manufacturing conditions of the black and white poly film.

Installation Tips

  • Single Layer Installation
    Single-layer greenhouse film should be installed snugly, but not overly tight, to accommodate natural expansion and contraction.

  • Double Layer Installation
    For double poly film installations, ensure enough slack is left in the top layer to allow for 12” to 24” of inflation.

Usage Scenarios

Choosing the right greenhouse plastic film depends on your specific growing conditions. Below are a few usage scenarios to help you make the right decision:

  • For Commercial Growers: If you're managing a large-scale agricultural operation, heat shrink wrap can offer superior temperature control, creating a snug, waterproof barrier that withstands extreme weather conditions.

  • For Hobbyists: If you're a hobbyist growing plants in a backyard greenhouse, black & white light deprivation films can help you control light exposure for optimal plant growth without breaking the bank.

  • For Specialized Crops: For crops that need strict temperature regulation, like certain vegetables or flowers, thermal greenhouse plastic film can help maintain a consistent environment by expanding and contracting with temperature changes.

Frequently Asked Questions (FAQs)

What is the difference between single and double-layer installations?
Single-layer films are installed snugly but not tightly, while double-layer installations include slack to allow for inflation, providing better insulation and temperature control.

How do I choose the right thickness or gauge for my needs?
Thicker films (higher gauge) offer more durability and are best suited for extreme weather or large-scale commercial operations. Lighter films are ideal for smaller greenhouses in more moderate climates.

How long do greenhouse films last, and how often should they be replaced?
Greenhouse films typically last between 3-6 years, depending on the material and exposure to weather conditions. Regular inspections will help you know when it's time to replace them.

What factors should I consider for temperature and humidity control?
Consider the size of your greenhouse, the local climate, and your crops' needs. Heat shrink wrap is excellent for controlling both temperature and humidity, while thermal films expand and contract with the temperature for added control.

Maintenance and Durability Tips

To maximize the lifespan of your greenhouse plastic film, follow these maintenance tips:

  • Regular Cleaning: Clean the surface of the film periodically using mild soap and water to remove dust, dirt, and other debris that can degrade the material over time.

  • Avoid Sharp Objects: Be cautious when working around the film to prevent accidental punctures or tears. Sharp tools or even wind-blown debris can damage the film.

  • Repair Small Tears: If small tears occur, they can often be repaired using adhesive repair tape designed for greenhouse films, allowing you to prolong the film's life without needing a full replacement.

  • Monitor UV Exposure: Excessive exposure to sunlight can weaken the material. Opt for UV-resistant films to minimize damage and extend durability.

Proper care and maintenance will help your greenhouse films last longer, ensuring better results season after season.

Environmental Impact & Sustainability Information

At Pro-Tect Plastics, we understand the importance of sustainability. Many of our greenhouse films are made from durable, recyclable materials, making them an eco-friendly choice for your agricultural needs. By selecting films with UV resistance and longer lifespans, you reduce the need for frequent replacements, minimizing waste and helping the environment.

We are committed to providing options that allow you to grow your crops efficiently while reducing your environmental footprint.

Weather Resistance and Regional Considerations

Different climates require different levels of protection for your greenhouse, and the right film can make all the difference:

  • Colder Climates: If you live in a colder region thermal films are ideal for insulation, helping to retain heat and extend your growing season even in lower temperatures.

  • Warmer Climates: For regions with intense sun and heat, black & white reflective films are perfect for controlling light exposure and heat. The white reflective side will direct light away from your greenhouse, helping to maintain a cooler growing environment.

Greenhouse Film Thickness Options and Their Uses

Pro-Tect Plastics offers greenhouse films in three thicknesses: 6 mil, 9 mil, and 12 mil. Each thickness serves different needs depending on your growing environment, climate, and the type of crops you're cultivating. Below is an overview of each thickness and its ideal uses:

6 mil Greenhouse Plastic

  • Best For: General-purpose, year-round use in moderate climates and small to medium greenhouses.

  • Durability: The 6 mil film is the industry standard for many greenhouse applications. It provides a good balance between flexibility and durability, making it suitable for most gardeners and small commercial growers.

  • Protection: This film offers solid protection against weather conditions, including UV rays and moderate wind. It's an excellent choice for light control and moisture management, typically lasting 3 to 4 years with proper care.

9 mil Greenhouse Plastic

  • Best For: Heavy-duty applications, larger greenhouses, or areas with more challenging weather conditions.

  • Durability: The 9 mil woven reinforced film is thicker and more robust, providing enhanced protection for those needing extra durability. It’s well-suited for regions with stronger winds or more intense sunlight.

  • Protection: This option offers better insulation than the 6 mil, which helps with temperature control and moisture retention. It’s ideal for growers who want to protect their crops from extreme heat or cold while maintaining a stable growing environment.

12 mil Greenhouse Plastic

  • Best For: Maximum durability in commercial operations or extreme climates.

  • Durability: The 12 mil woven reinforced film is the thickest and strongest option available. It provides superior protection against physical damage, UV exposure, and harsh weather conditions, including strong winds, heavy rain, and snow.

  • Protection: With the highest level of insulation, this film is perfect for maintaining stable temperatures in greenhouses used for temperature-sensitive or high-value crops. It’s designed for long-term use, offering the best protection in even the most demanding environments.

How to Choose the Right Thickness

  • Climate Considerations: If you’re in a moderate climate with occasional weather changes, the 6 mil film should provide sufficient protection. However, if you experience harsher weather conditions, such as high winds, extreme heat, or heavy snowfall, the 9 mil or 12 mil woven reinforced films offer greater durability.

  • Greenhouse Size and Crop Type: Larger greenhouses or commercial operations can benefit from the added strength of 9 mil or 12 mil woven reinforced films, especially if you’re growing temperature-sensitive crops that require strict environmental control.

  • Duration of Use: If you’re looking for a long-term solution or growing high-value crops, consider investing in the thicker 9 mil or 12 mil films for better longevity and protection. The 6 mil film is ideal for more general use and shorter-term growing operations.
