About greenhouse plastic film

Types of greenhouse plastic film

Greenhouse plastic films come in various types, each suited to different environmental and agricultural conditions. The greenhouse plastic film type greatly impacts crop growth, energy efficiency, and cost-effectiveness.

Long-term durable film

Compared to normal film, this structure is specially formulated to last longer in harsh weather and UV exposure. It is thicker, resists wear and tear, but harder to work with due to its weight. It’s good for places with strong winds or lots of sun that need extra weather protection.

Temperature retention film

This film helps maintain warm or cool temperatures inside the greenhouse as needed by the crops. It has special glazes that keep heat better than regular films. It is ideal for places where temperatures fluctuate too much for plant health. It helps define the climate for growing all year.

Inflatable double-layer film

This type includes two layers of film that are separated by a small amount of air, which acts as insulation. The air space reduces heat loss, improves energy efficiency, and lowers heating costs. It is useful for regions that require efficient temperature control and energy savings.

Anti-drip film

Water condensation on the greenhouse plastic film can drip back onto plants, harming them. Anti-drip films solve this by evenly spreading condensation along the film so it doesn't fall in drops. This protects crops and increases humidity levels for better growth. It is ideal for any greenhouse where condensation is a problem.

Colored films

The colored greenhouse film allows specific wavelengths of light for better growth. For instance, red film promotes flowering, blue film boosts foliage. It is useful for tailoring light conditions to particular crops or growth stages. This optimizes photosynthesis and crop yields.

Polyethylene film

Polyethylene, or PE plastic film, is the most commonly used greenhouse covering worldwide. It is cost-effective and provides good light transmission, typically around 85%. The film is affordable and practical for small to large-scale commercial greenhouses, as well as DIY home gardening solutions.

How to choose the greenhouse plastic film

Selecting the right greenhouse plastic film involves considering factors such as the local climate, crop requirements, and film durability. Here are some guidelines to choose the most suitable plastic film for various growing needs:

Environmental conditions

Consider typical weather patterns and temperatures. Look at the anti-drip film if condensation issues have been reported. The polyethylene film is best because it is simple to apply and very tough.

Crop needs

Determine what crops will be grown. The colored films provide special light to make particular crops grow better. The temperature film helps keep the right heat or coolness inside for plants. Select films based on desired crop yield and quality.

Clarify greenhouse

Identify what kind of greenhouse will be used. The double poly film is great for homemade greenhouses that need more energy savings. Inflated plastic is excellent for large commercial buildings to save on heating bills. Pick a film that suits a small or large growing space.

Longevity and expense

Analyze how long each film option lasts and its cost upfront. Condensation control films drape dew and humidity better. Long-lasting plastics are worth the money up front because they stay in place during storms. Weigh the budget against durability for a wise choice in the greenhouse.

comerciais and agricultural uses

Greenhouse plastic films have diverse applications and serve many purposes in commercial and agricultural spaces, providing a controlled environment for plant growth.

Scope of commercial application

The growth of vegetables, fruits, and flowers all year is possible, increasing sales. The plastic increases yields by allowing crops to be ready faster. Producing out-of-season plants makes extra money. Market value and profit go up from using the right film for crop needs.

Protection from weather and pests

The greenhouse plastic film keeps bad weather and bugs out. It protects against rain, snow, wind, and insects, which boosts production. Less damage means more healthy plants. Proper films cut down pest problems and disease spreading, allowing farming in peace.

Fruit

Berries like strawberries, raspberries, and blackberries thrive inside plastic films. The film maintains ideal conditions for berries, leading to sweeter fruit. They grow reliably all season, which makes the supply steady. Greenhouse growing provides fresh, healthy berries year-round for happy customers.

Flower production

The film is critical for producing flowers and ornamental plants profitily. Plastic maintains the right temperatures and light for floriculture. Flowers can be cultivated year-round and delivered consistently. Production quality improves, offering vibrant, in-demand blooms to distributors and retailers.

Tropical and subtropical fruits

Greenhouse plastic film allows tropical fruits like bananas and pineapples to be grown in non-native regions. It creates a suitable environment for these heat-loving plants, enabling their production outside tropical zones. This expands the variety of fruits available locally, increasing accessibility and freshness for consumers.

Herbs and specialty crops

Plastics aid the growth of herbs and unique greens all year. Demand for fresh oregano, basil, and other herbs stays high. The film improves orders by enabling consistent supply. Specialty greens flourish inside, offering health-conscious clients fresh salad ingredients any time.

Energy-efficient production

Low heating costs allow greens to be grown cheaply. Plastics help temperatures stay stable, cutting energy bills. Dans or heating up pays less each month, keeping expenses down. More profits can be reaped since crops can grow affordably in the greenhouses all year.

How to DIY and replace the greenhouse plastic film

DIY and maintaining the greenhouse plastic film requires proper care and attention. Choosing the right film is essential depending on the local climate, crop requirements, and budget. Durable films such as polyethylene or anti-drip films are ideal for protecting plants from harsh weather conditions, UV exposure, and condensation.

Removing old film

The old plastic film should be carefully removed by starting at one corner and slowly pulling it off, taking care not to damage the structure. The film must be carefully rolled up and disposed of properly or recycled, as some areas have recycling programs for greenhouse plastics. A thorough cleaning of the frame is necessary to prepare for new film installation.

Measuring and installing new film

Measuring the greenhouse size precisely is important for an accurate fit. Buyers should buy a new film that perfectly matches the dimensions of the greenhouse structure. Before applying the new plastic, a helper is required to hold the film while the frames are rolled out. The film should be draped evenly all around the greenhouse.

Securing film

Starting from one side, the film should be pulled tight to remove any wrinkles or bubbles. Use clips or a construction stapler to secure the film tightly to the frame, beginning from the base and working upward. Use at least 1 inch wide strips of wood or 2 x 4s to secure the plastic film on the frames firmly.

Cutting excess film

For a neat finish, any extra plastic film should be carefully cut using a sharp utility knife along the edges of the frame. Tension should be re-checked after cutting to ensure the film is still tight against the frame. The film should then be stapled securely to prevent wind or weather from loosening it.

Applying tape and repairing film

Special repair tape made for greenhouse films should be used on areas where the film has punctured or torn. Repairs should be carried out immediately to prevent further damage from spreading. The tape should be applied cleanly and firmly over punctures to protect plants and maintain a controlled environment.

Q&A

Q1: How long does a greenhouse plastic film last?

A1: Generally, greenhouse films last from one to four years, depending on the type. Standard polyethylene endures one to two years, while tough UV-resistant film spans three to four years.

Q2: When should greenhouse plastic film be replaced?

A2: The plastic should be replaced when clarity declines, allowing less light, or when tears and elasticity wear out. Ageing plastic compromises temperature control and crop growth.

Q3: What thickness greenhouse film lasts the longest?

A3: A 6-mil thick greenhouse film endures the longest. The increased thickness shields against UV rays, winds, and elements' harshness, extending the film's lifespan. It strikes a balance between visibility and strength.

Q4: How do you extend the life of a greenhouse plastic film?

A4: Coatings like anti-dust or anti-condensation films shield the plastic from scarring and internal moisture. Regularly cleaning the film further reduces UV degradation exposure.
