Definitions
- the invention relates to a. Plastic film, which consists of thermoplastic materials and can be used as a flat cover or tunnel for covering vegetables, fruit or flowers.
- the film can be made of, for example, polyethylene, polypropylene, polyester, PVC and others, but preferably polyethylene, such as LDPE, LLDPE, HDPE, VLDPE, mPE and EVA, or renewable raw materials in a thickness of 10 ⁇ m to 250 ⁇ m.
- polyethylene such as LDPE, LLDPE, HDPE, VLDPE, mPE and EVA, or renewable raw materials in a thickness of 10 ⁇ m to 250 ⁇ m.
- perforated foils which are mainly used for early harvesting.
- Nonwovens which are also used for early harvesting, but also as autumn coverings against frosts.
- Slit films are mainly used 'for by growing vegetables.
- Perforated films are used in the packaging industry.
- the currently used perforated films have the disadvantage that they are very susceptible to wind and therefore exert a strong blow movement on the plant, which can lead to high crop failures.
- a major disadvantage of conventional perforated film is that pests can penetrate the film through the punched holes.
- bird damage through the perforations can lead to plant damage. Penetrating hail can also cause plant damage.
- the currently used fleece has the disadvantage that it literally sticks to the plants when it rains and crushes them. During long periods of rain, this can lead to considerable damage to sensitive plants.
- the biggest disadvantage of the fleece is the poor light transmission. As a result, the plants are not hardened against UV radiation. In strong winds, the film is often torn off the ground anchor. Perforated films are mainly used for the packaging of vegetables, fruits and flowers to keep a better microclimate under the packaging.
- the invention has for its object to provide a plastic film that allows a best heat effect and a very good microclimate and prevents the penetration of pests. Furthermore, good stabilization against wind movements should be achieved in order to avoid a striking movement. The best possible early harvest effect should also be achieved and the starting moisture of the usable field capacity should be available to the plant for longer.
- thermoplastic plastic films according to the invention with their perforation patterns can be produced on a manufacturing device practically as endless webs with a predetermined width or as a predetermined tarpaulin section and the desired perforation patterns can be made in the film using a punching or laser technique.
- Stabilizing fabric inlays can also be incorporated into the side strips or a continuous hose system can be attached to the side panels.
- thermoplastic film according to the invention is distinguished by the fact that it can be provided with various perforation patterns, the slits by means of which they are introduced being always arranged in such a way that one or more flaps are created functionally.
- the plastic film according to the invention is thus a closed film in normal weather conditions. This creates a very good heat retention effect as well as a very good retention effect of the starting moisture with a very good microclimate.
- the first self-regulating early harvest film that opens its flaps inwards or outwards, depending on the weather.
- the slotted flaps open and a breathable opening is formed.
- the flap can be determined by the slitting. For example as shown in Fig. 1 for northern regions. The variant in Fig. 2 would be more suitable for southern regions. Variants according to FIG. 3 and FIG. 4 are suitable for high-wind cultivation areas and dry areas.
- the flap to be opened or closed must point in the wind direction.
- the cross-shaped opening according to FIG. 1 or the Y-shaped opening according to FIG. 7 can be used, since they have the greatest heat effects and great wind stability. Further perforation patterns are shown in FIGS. 5 and 6 and expand the design options of the plastic film according to the invention.
