Description
Technical Field
The utility model relates to the technical field of films, in particular to a food packaging composite film.
Background
The food packaging film is a high polymer material used for wrapping the surface of food, isolating and decomposing microbial bacteria and entering foreign pollutants, and preventing and prolonging the deterioration of the food. The food packaging film mainly comprises a photocatalytic inorganic antibacterial film, a natural and high molecular antibacterial film, a composite antibacterial film, an inorganic antibacterial film and an organic antibacterial film.
At present, the existing food packaging film is generally rolled into a cylinder, when the food packaging film is required to be used, one end of the outermost side of the packaging film can be pinched and lifted, the packaging film is lifted to a required length and then is torn, the torn packaging film covers the surface of food to exert the effect, however, the food packaging film is generally a film, the smoothness is poor, the lamination between layers is very tight after rolling, the end of the outermost side of the packaging film is difficult to lift, and the operation of lifting the packaging film is very troublesome.
Disclosure of Invention
The utility model aims to provide a food packaging composite film for solving the problems, which is convenient to uncover.
The utility model realizes the aim through the following technical scheme that the food packaging composite film comprises a base layer, wherein an inner layer is arranged on the lower surface of the base layer, a plurality of protruding blocks are arranged between the base layer and the inner layer, the protruding blocks are hemispherical, the protruding blocks are made of resin materials, the positions, corresponding to the protruding blocks, of the surface of the inner layer are provided with protrusions, and gaps are formed between the adjacent protruding blocks.
As a further arrangement of the utility model, the upper surface of the base layer is provided with a corrosion-resistant coating, and the corrosion-resistant coating is a polytetrafluoroethylene layer.
As a further arrangement of the utility model, the base layer comprises a core layer made of TPU material.
As a further arrangement of the utility model, the upper surface of the core layer is provided with a first cushion layer, and the first cushion layer is made of PE material.
As a further arrangement of the utility model, the lower surface of the core layer is provided with a second cushion layer, and the second cushion layer is made of EVA material.
As a further arrangement of the utility model, the inner layer is made of PVC material.
Compared with the prior art, the utility model has the beneficial effects that:
the utility model has better corrosion resistance, the bulges are arranged on the surface of the inner layer, gaps are formed between the adjacent bulges, and the top surfaces of the bulges form a blocking plane together, so that when the film is rolled, the layers cannot be completely tightly adhered due to the blocking of the bulges, so that the gaps can be ensured to exist all the time, one end of the outermost side of the packaging film can be conveniently found when the film is required to be used, and the application of force can be conveniently carried out to lift the one end of the outermost side of the film due to the existence of the gaps, so that the operation of uncovering the packaging film becomes easier and more labor-saving.
