Double adhesive plastic packaging covering consisting of a main surface 1 in the form of a quadrilateral 1a or parallelogram 1b or rhombus 1e or triangle 1d or polygon 1c or round 1f or with a hole 1g or tube 1h which is made of polyethylene or agricultural quality plastic or soft or hard plastic or heat-shrunk plastic, reinforced or aeroplast or double plastic to ensure durability. The size of the main surface 1 varies depending on the object to be covered and its shape. The main surface 1 may be made from material with different colours. At the ends of the main surface 1 there is double adhesive. Around the ends of the main surface 1 a plastic surface is stuck 2, a peripheral surface 3 and, after millimetres, there is further adhesive 2 to ensure the strength of the weld of the main surface with the peripheral surface 3. The weld may be 0.3 millimetre and is a thin weld for plastic coverings of small dimensions, the width of the weld may be from 1 millimetre to 3 centimetres. The peripheral surface may be of transparent simple plastic or peripherally reinforced plastic or reinforced plastic on one side for greater strength where needed. The double adhesive plastic packaging covering main surface 1 may have the shape of a parallelepiped 1i and have the two parallel sides and the base open. There is double adhesive at the ends of these sides 2a which unites the main surfaces 1i with the adjoining surface 4. The basic idea of the invention is to cover materials of any shape or dimensions which are in an outdoor area or in containers or lorries or anywhere else and which require protection or packaging. The advantages of the invention are that the covering or packaging can be carried out anywhere on any volume, object or shape. It is applied to and embraces the material. It is simple to position and has a low cost. |
