'Sterilite Premium'
Polythene (720g/180mu) …      

XL Horticulture's specially developed polythene greenhouse cover has been designed to reduce disease and pests in polytunnel structures and is an excellent choice for Organic Growers, whilst Sterilite Premium Polythene's latest thermal filters can also save up to 20% on heating costs and can keep out frosts of up to 4 deg C.

Sterilite's ability to block out UV up to 380nms, reduces diseases like Botrytis and Mildew that need a certain level of UV to be able to reproduce, hence by blocking the UV to this level, you can keep diseases under control without using chemicals with no adverse effect on the growth of the plants.

Recent trials at Wellesbourne have shown that using Sterilite Premium Polythene reduced the incidence of mildew from 90.9% down to 43.7%. Flying insects also see in UV light, but because they can't see they don't fly. Trials in XL's own nurseries show that introduced aphids will form small colonies, but not spread through the house.

The benefit to you is that this all helps to reduce fungal diseases and aphid attacks, which reduces the need for harmful chemicals, and the labour costs of applying them.

Sterilite Premium Polythene Full Specification .....

• Partially UV Closed - Sterilite Premium Polytunnel Polythene blocks out UV up to 380nms. Diseases like Botrytis and Mildew need UV to be able to reproduce. By blocking the UV, you keep diseases under control without using chemicals. Recent trials at Wellesbourne have shown that using Sterilite MDF Polythene reduced the incidence of mildew from 90.9% down to 43.7%. flying insects also see in UV light. Because they can't see they don't fly. Trials in XL's own nurseries show that introduced aphids will form small colonies, but not spread through the house. The benefit to you is that this helps to reduce fungal diseases and aphid attacks, which saves you money on harmful chemicals, and the labour costs of applying them.

• Temperature Control Film - Sterilite Premium Polythene uses the latest aluminium thermal control additive which reduces the temperature in the summer better than XL's previous thermal barrier additives (Calcium). Constant research has developed the aluminium based Near Infra Red Reflector which has now replaced the previous calcium based filter to give an extra 10-15% than previously, making it cooler by day to create a much pleasanter working environment.

• Thermically Efficient - Sterilite Premium Polythene's thermal filter can save up to 20% on heating costs and can keep out frosts of up to 4 deg C. It works by reflecting the stored heat from the plants, pots and soil etc. back into the structure once the air temperature drops below the temperature they have risen to during the day. Sterilite MDF Premium Polythene can reflect as much as 86% of this heat back into the structure. Benefits are reduced heating costs and less damage from frost.

• High Diffusion - Sterilite Premium Polythene is a High Diffusion film scattering light as it enters the structure. This prevents shadows created by the framework of the structure. The benefit is that the plants don't shade each other and notably grow much more evenly and also give increased yields.

• Anti Fog / Anti Drip - Sterilite Premium Polythene has an Anti Fog / Anti Drip agent which breaks down the surface tension of the condensation droplets so that they run down the sheet, reducing drips and subsequently retaining light clarity.

• Strong - Sterilite Premium contains a special metallocene additive, which adds tremendous strength to the film.

• Thickness - 720g / 180mu film.

• Five Year Life - Sterilite Premium Polythene has a Five year life Guarantee against premature UV degradation of film (guarantee terms and conditions apply).

• Use this film - For crops that you want to grow without using chemicals and all crops that will be heated. Many growers use this for bedding plants as well as nursery stock, salad crops etc.

Please Note - Sterilite Premium Polythene will not totally eradicate all diseases and insect pests. However as part of an integrated pest management growing system it will make a significant reduction in pest and disease.
